Much More Than a Fish Story I have had the good fortune of experiencing some amazing things in my lifetime, and I can say without hesitation that snorkeling an ocean reef ranks at the top of the list. My first venture into the magical and almost incomprehensible world of undersea life is decades behind me now, but I was awestruck then and the sense of wonder I felt left a lasting impression. These days, my close encounters with marine life tend to involve bait and a boat, but I am still fascinated by the notion that fish live out their lives completely unaware of the world that exists beyond the water’s edge. On the rare occasion that a fish finds itself on the end of my line, I imagine that for the fish, the experience of being caught, reeled aboard a boat and released back to the water must be the equivalent of a human being abducted by aliens. I acknowledge the strong possibility that my fascination might not be reciprocal. Maybe the fish don’t care at all about the who, what, where and how of what happens on land, but I’m certain I am not alone in my very human curiosity about what goes on in the world below the sea. Here in St. Louis, the idea of developing a premiere marinelife attraction has been floating around for long time. Some of the country’s first tank exhibits made their appearance at the 1904 World’s Fair, and those of us who have been around awhile probably remember a scheme to establish a major aquarium feature as part of a master plan for the St. Louis river front that surfaced in the early ‘90s. Like other big concepts that require a great deal of vision and commitment, this one has taken some time to materialize, but St. Louis-based Lodging Hospitality Management has finally made the long-held local dream a reality. The St. Louis Aquarium at Union Station will open in December with 44 exhibits and 130,000 animals representing 257 different species. As you can imagine, building a two-story, 120,000-square-foot aquarium inside a National Historic Landmark structure dating back to 1894 presented some unique challenges. From demolition to site preparation to completion, St. Louis building companies large and small have contributed their expertise and creative genius to overcome those challenges and bring this project to

fruition. We are pleased to bring you their story in this issue of St. Louis CNR. When the doors open next month, visitors entering the aquarium lobby will be dazzled by a 14-foot-tall clock tank holding 10,500 gallons of water and a collection of colorful discus fish native to South America. Arched ceilings will add to guests’ sensation that they’re embarking on a train journey, especially as their ticket (which includes a specific “boarding” time) is called out and they enter simulated, life-size train cars to begin their tour of the aquarium. The River Monster exhibit, designed and constructed to look like the ruins of a South American temple, will house enormous fish native to South American rivers and lakes. Not surprisingly, the Piranhas will be housed in their own separate exhibit. No doubt one of the most talked-about experiences will be an exhibit known as Shark Canyon, which will house 60 sharks and rays. A walkway will lead visitors down below the 250,000-gallon tank, some 18 feet deep at its deepest point, for a close-encounter moment with schools of sharks swimming all around and directly over their heads. I can’t wait to check it out and I am excited to think that with the opening of the St. Louis Aquarium, I won’t have to don flippers and a snorkel to hang out with the fish on their own turf. I wonder if the aquarium’s residents will be as impressed as we are by the genius that went into creating their new home.

Architect’s Mechanic’s Lien Filed Too Late: Timing Is Everything, Appellate Court Says Missouri’s Eastern District Court of Appeals recently decided that an architectural firm filed its mechanic’s lien too late. Consequently, the lien was not enforceable. The case is Bates & Associates, Inc. v. Providence Bank & Vision Ventures, LLC, 2019 WL 4419698, September 17, 2019. Architects rarely file mechanic’s liens in Missouri. Their liens are against real estate. Architects typically work for real estate owners. Liens tend to compromise such working relationships, both on current matters and future opportunities. The architectural firm in this case is Bates & Associates Inc., a licensed architectural firm under Missouri law. The original owner of the real estate was Vision Ventures LLC. Providence Bank became the owner through a non-judicial foreclosure. Bates sued both to enforce its mechanic’s lien. While filing an architect’s lien is uncommon, the facts in this case, although somewhat complicated, are not that uncommon for architects and owners on construction projects. In 2013, Bates entered into a contract with Vision for architectural design and construction services for a senior care facility. The project was located at 17655 Wild Horse Creek Road in Chesterfield. Financing was involved to make the project a reality. There was an initial loan secured by a deed of trust for $2.48 million in 2008. An additional promissory note secured a modification to the deed of trust for an additional $1.37 million. Vision defaulted on the loan and note by failing to make all of the payments when due. Vision also filed for Chapter 11 bankruptcy in March 2015, listing Bates as an unsecured creditor. Bates filed its lien on July 15, 2015 for the work performed for Vision. By doing this, Bates obviously hoped to become a secured creditor in the bankruptcy estate. Under Missouri law, a mechanic’s lien relates back to the first day of work, regardless of when the lien was filed – provided it was timely filed. This can provide a potential priority when there are several secured creditors. Two days later, the non-judicial foreclosure took place. Providence obtained title to the property. Bates filed a three-count petition against Vision and Providence. In Count II, the mechanic’s lien count, Bates sought $305,279 against both, asserting its lien was superior to Providence’s interest in the property. Bates sued Vision in Counts I and III for breach of contract or in the alternative quantum meruit (for services rendered where there is no specific contract). After a bench trial, the trial court awarded Bates $276,000 on its breach of contract claim. Expressly finding there was a contract, the court denied the claim for quantum meruit. Under Missouri law you can recover for one or the other, but not both. The trial court also denied Bates’ claim to enforce its mechanic’s lien and granted Providence’s counterclaim to quiet title to the property. This gave Providence ownership over Bates. The trial court concluded that the architectural services were not directly connected to any construction or other improvements to the property. It also concluded that Bates did not timely file its lien. The appellate court focused on the timing issue.


CNR St. Louis Construction News and Review - www.stlouiscnr.com

What makes the facts of this case somewhat common is that the architect performed design services under an original 2013 contract. Then Bates did work later that it alleges was pursuant to this original contract. Architects often find themselves in this situation. If Bates was correct, its lien could have applied to all the work it did from the first day of work until the last. The reason the timing is important is because a mechanic’s lien under Missouri law must be filed within six months of the last day of work performed by that party. Missouri law affords no grace period. A lien filed one day too late is the same as a lien filed one year too late. Under the original contract, Bates’ last day of work was July 7, 2014. A lien for that work expired on January 7, 2015. Bates filed its lien on July 15, 2015. Bates claimed that it performed additional work between January and March 2015 and this work was an extension of the original contract. Bates’ timesheets showed internal meetings about the project. In February 2015, Bates sent Vision a proposed contract for additional services in the amount of $70,000. Bates’ proposal included removing kitchens from the secondfloor apartments and a redesign on each floor to reduce overall square footage. This work did not advance beyond discussions in meetings. There was a fact dispute as to whether Vision agreed to the additional services. Appellate courts defer to the trial court’s determination of fact questions. The trial court found there was an agreement for the original work, but it is unclear if the court’s judgment included any of the later work under the breach of contract claim. Appellate courts decide for themselves legal questions. In this case, the legal question on appeal was whether the work from January through March 2015 was in accordance with the original 2013 contract and thus lienable according to Section 429.015 of the Revised Statutes of Missouri. The contract between Bates and Vision required that any additional changes to the original scope of Bates’ work required written authorization. In this case, there was no written authorization. The appellate court concluded for this reason alone, the later work was not within the original scope of the contract and thus not lienable. In addition, the Eastern District also concluded that the additional work to develop and communicate its proposal was not necessary to complete the original contract. The drafting of a proposal for additional services, according to the court, did not constitute a lienable improvement upon the land. The court concluded that a “proposal for a contract for additional services is not the same as a partial or complete set of designs.” James R.

Sales Excuses in Place of Sales Effort: Smart Sales Professionals Ditch the Excuses I’ve worked with hundreds of people responsible for their company’s sales effort. I’ve seen some incredible individuals who seem to be in the mix on every deal they go after. They nail it and ask little in return, except for their bonus or commission check. Their companies thrive and their profit margins are strong. The economy – whether poor or booming – doesn’t affect them. They are producers, simple and true. They may not be the thriftiest among us, but who cares if they bring home the bacon? For those of you out there who fit in this category, I salute you. Then there’s the other category – folks who complain about every aspect of sales, who blame the economy and who complain that everything is about price. They find fault with their own company and are seldomly proactive. They argue with you that sales work doesn’t make a difference, but when they get a deal, they’ll tell you how they learned the inside track on the project. It can drive a manager crazy. These responses are very simple to explain. They’re excuses. I have contractor clients who are securing work in minimum or no-bid competition. They are winning without being the low number and are getting good margins and repeat business. Their clients call them first or keep them on a short list. These contractors set aside time in every work week specifically for sales work. They understand there is no more important aspect to their business than sales. They market properly and do the extras to develop relationships. These folks are networking and not qualifying away opportunity. They don’t discount those who are consultants regarding sales and marketing as less than valuable. They are regularly looking to grow and learn in relation to their sales skills. Not all of them come by it naturally. Some of them were also excuse makers at one time. The change came for some when there was virtually nowhere else to go but sales work to gain profitable business. A few were sweating things out before they turned the corner. The first step to excelling in the way you sell is to quit with the excuses. When I begin working with a someone who is a sales agent for his or her company, the first place I start is to discover how that individual is using his or her time. Most of us get things thrown at us regularly that lure us off task. Having a plan in place that forces you to incorporate sales time can begin to stabilize your schedule. The more you learn and train your customers, the more control you have over your schedule. My next step is to find out why they feel they’re not enjoying the sales success they’d like. This flushes out the excuse. Trust me, there are only three to four excuses in total within the construction industry. These excuses might have slight variations, but really, they’re all very common – although they feel unique to each person. Setting a sales strategy for specific customers and targets is the next step. If you were to do only these few steps, you’d be doing more than most contractors, or for that matter, companies in general. The pressure to perform in a construction environment as competitive as the current one is great. Many experience failures at a rate they’ve never seen before. The easiest explanation is to find fault in some other area besides one’s sales work. The more difficult response is to adjust your sales approach and focus the same level

of attention on that effort as you would to finding profitability on a project. Refreshing marketing collateral, finding time to connect through business-oriented, physical social networking, establishing a strong digital footprint and setting an aggressive call schedule takes time when combined with planning. Finding excuses not to take that time will only result in the same pattern of sales. If that pattern is trending down, deeper it will go. So many contractors are looking for ways to get an edge or find new opportunity. How do you propose to do this if you are continually excusing a weak or ineffective sales effort? Multitudes of contractors across the country are struggling with the challenge of getting business. Productivity for most contractors is at an alltime high. Field performance is at a premium. Many are working ridiculous hours and giving the operations aspect of their business everything they have. They’ve cut costs to the bone. Still, there’s no light at the end of the tunnel. As we head into the winter, we are entering a prime sales season. Filling your pipeline with quality opportunities now will bring results in the spring. Evaluate your sales work and determine if you need to make adjustments as opposed to excuses. If you are not an excuse maker but things aren’t where you want them, change your sales strategy. Find areas of weakness and correct them. Maximize your strengths and invest in the customer relationships you have. Expand your network and get out of the office because there aren’t a lot of customers there. I’ve been watching the continued trend of reducing personal contact with customers. Technology has made it easier to do so. I’ve watched young, millennial sales personnel sit in front a potential customer and blast them with data and information. The datadriven sales processes coming into prominence will do nothing more than increase pricing focus. Unfortunately, in construction, price is a poor decision-making factor if the facility is poorly built or not built to the project owner’s wants and needs. Safety, quality of materials and skill of labor begin to become watered down in the quest for the lowest bid possible. If you don’t think that’s true, you’re not really looking very closely. Construction lives and breathes with sales. The competitive differences are very real. With millennials becoming decision makers, sales agents need to realize they’re selling the value of relationship, skill and reputation, not simply the project. Construction has never been black and white. Just ask the excavator who hits bedrock unexpectedly, the demo contractor who discovers an environmental hazard behind a wall or the masonry contractor who discovers the plans are an 1/8 of an inch off. There is still a lot of selling to do in construction, and it needs to be done effectively. One of my most consistent points is simply this: If sales is the most important part of your business, why in construction does it not get the same level of attention that it merits? Without sales, you have nothing else. Construction isn’t so unique that you don’t need to focus or improve in the area of sales. You must, just like in any other business.

More than 500 windows and 700 pieces of glass have been replaced – with more to come – in the redevelopment of a Midtown St. Louis landmark remembered for its military and sporting presence over many decades. By KERRY SMITH


CNR St. Louis Construction News and Review - www.stlouiscnr.com

The Armory, located at Market and 36th Streets, is a massive 260,000-square-foot structure that was recently added to the National Register of Historic Places and developer Green Street St. Louis’ $83.4 million redevelopment venture. Bounded by Highway 40 on the south and Market Street on the north, the enormous structure was completed in 1938 to house the 138th Infantry Missouri National Guard, who remained there for 33 years. During the 1950s and 1960s, the building hosted tennis tournaments, bugle corps competitions, Saint Louis University dances and even the Grateful Dead. Green Street purchased the Armory structure in 2016. Although it had stood vacant since 2005, the bones of the building remain strong. In 2017, Green Street began working with Arcturis on a master plan and the vision began for the Armory’s segue from hosting military, athletes and artists to attracting young urban entrepreneurs and tech firms into Class A office space. Between 750 to 1,000 people are expected to work in the space when it is fully leased. The Armory is located within two blocks of the Grand (Avenue) MetroLink station and one stop from Cortex. “The Armory represents a unique building with a rich history,” said Phil Hulse, managing principal and CEO of Green Street St. Louis. “Our interest here is driven by the $8 billion of investment that’s already in existence in the Downtown-Midtown corridor. Of the mix of projects currently in play, the Armory is the largest. We’re excited to be developing what we envision as another mecca for innovative firms.” The two-phase, multi-year redevelopment includes phase one – the Armory building itself – and a future phase across the street, directly to the east, which will consist of leasable residential living units. Hulse said the goal of the project is to retain the history of the Armory while building out the stately structure’s interior to accommodate growing start-up firms and others. The residential component will offer employees a live-work-play environment. “The synergy that’s already around us with Saint Louis University, Cortex, City Foundry STL, The Grove, Washington University in Saint Louis, Forest Park and more

In addition to serving as a future hub to multiple office tenants, The Armory is one component of The Armory District, a dynamic development featuring upscale living options, a restaurant, structured parking, a Greenway path connector and a location that's central to surrounding major commercial and mixed-use destinations. Vantage points from atop The Armory afford panoramic views of downtown St. Louis. is providing us with momentum as we program what we’re creating here,” Hulse said. “As with any city that is undergoing a vibrant transition, we’re all working in tandem to program how best to put the pieces together,” he added, “and the Armory is a significant piece.” Pete Arman, president of Green Street Construction, said transforming the 81-year-old building is moving forward now that major environmental remediation and replacement of key structural elements have been accomplished. More than 6,000 tons of debris and materials were removed during the demolition phase. Scores of tennis balls – a nod to a chapter of the building’s past when tennis greats such as Arthur Ashe spent time there honing their craft – are but one example of the artifacts left behind and discovered as Green Street began its work. Extensive tuckpointing of the Armory’s brick exterior was another task that Green Street completed over the past 12 months, in addition to major stone repair. Arman


said exterior work also included new glazing on the upper clerestory portion of the structure’s gabled high roof that runs hundreds of feet along the entire length of the roof ridge, as well as two levels of punched windows. Windows surround the flat roof system on four sides. New construction included replacement of 100 percent of the structure’s massive, sloped roof that included roof plank, insulation and shingles. Drilling micropiles into place under 36 of the structure’s more than 150 original columns was another big facet of the construction work thus far. “The real meat and potatoes of the new construction will entail building two levels of steel decks as part of the full shell buildout,” said Arman. Stairways, highspeed elevators and drywall for corridors and common areas and restrooms will also be part of the buildout. “We’ve proactively proceeded with shop drawings and orders for the elevators and other long-lead items, and we’re anticipating that the remaining project financing will be in place by the end of this year.”

CNR St. Louis Construction News and Review - www.stlouiscnr.com

Adding two new floors where the drill hall once stood, said Liz Austin, vice president of marketing at Green Street, is accommodating the infrastructure needed to offer the massive space as a Class A office. The first floor alone spans 80,000 square feet. Second floor square footage totals 72,000. The third floor’s square footage is 39,500 square feet. The basement level, in excess of 62,000 square feet, will offer indoor parking for 200 vehicles. The one-acre rooftop will offer event space and a garden. Solar power will be harnessed to heat the building’s interior. Project partner Arcturis joined Green Street early on in taking a sustainable approach to master planning what will eventually be known as the Armory District – inclusive of both office and residential phases – with the long game in mind, according to Hulse. Arcturis is project architect for phase one of the project. Arcturis Principal Megan Ridgeway said the whole approach to the Armory

redevelopment has been to preserve the iconic nature of the historic building while repositioning the building’s function to attract creative office users. “Our responsibility architecturally was to honor a historic structure that is so robustly built with exquisite exterior detailing, to continue to restore it and let it shine while infusing the building with more modern elements that catapults the Armory into the future,” Ridgeway said. The design represents a dichotomous nature, according to Ridgeway, that includes the building shell and the exterior envelope. “When you enter the building, that’s when things feel very new and dramatically different,” she said. An 11,000-square-foot atrium filled with natural light pouring in from the secondstory windows defies the dark interior core that one might expect when looking at the exterior shell. Arcturis’ and Green Street Construction’s task of replacing the hundreds of windows called for acoustically sensitive glass, particularly on the north façade, to buffer the sound produced by vehicles traveling along nearby Highway 40 for future occupants working in the building. KPFF provided structural engineering services on the project. Project Manager Alan Scott and Project Engineer Joe Carpenter began working on the Armory three years ago. “The building is uniquely configured,” said Scott. “You have a domeshaped, low, flat roof with the domed portion over what originally served as the drill hall.” KPFF strengthened portions of the low, flat roof to support the rooftop amenities. Strengthening the existing low roof reinforced concrete structure proved challenging, said Carpenter, due to three different standard strengths of rebar utilized when the building was originally constructed decades ago. KPFF’s scope of work also included identifying selective sampling of small sections of existing rebar in different locations throughout the building since no documentation existed as to what the original strengths of the rebar were. Underpinning – strengthening the additional foundations to support the two additional floors that were being built – was another chief facet of KPFF’s work on the Armory. KPFF performed many loading design requirements on the building’s original concrete columns, which ultimately

required installing four tubes around each existing footing and drilling holes down to bedrock to facilitate the installation of micropiles. A critical artery that ties the Armory and nearby developments together is the Chouteau Greenway. The trail system, according to Great Rivers Greenway CEO Susan Trautman, will connect the Armory District with City Foundry STL, the future Iron Hill mixed-use development adjacent to the new SSM Health SLU Hospital, and on to the Gateway Arch, Forest Park, Tower Grove Park and other well-traveled St. Louis destinations. “The Armory is at the

crossroads of these routes,” Trautman said. “Bridging between the decks of Interstate 64 will connect the (City) Foundry (STL) to the Armory and beyond. We’re looking at equity and economics and thinking comprehensively about how this (Greenway) can transform the city.” The Armory’s first office tenants are anticipated to move in during early 2021. Residential design work on phase 2 is expected to conclude in late 2020 with residents moving in sometime in 2022. Green Street is currently developing 15 other projects in and around St. Louis.

Acoustics Specialists Urge Owners to Consider Sound Implications at Project’s Start


CNR St. Louis Construction News and Review - www.stlouiscnr.com

Open concept layouts of commercial spaces are great for attracting and retaining workers. But without the proper acoustical considerations, these environments and others can be at best distracting and at worst unbearable in terms of noise. According to acoustical consultant Patty Gaus, owner of Maplewood, MO-based Gaus Acoustics, bringing acoustical needs into the conversation with owners and contactors very early on in a project’s life cycle is critical rather than bearing the cost and dissatisfaction of having to face noise mitigation on the back end. “Our approach to the entire building envelope and system is holistic,” Gaus said. “From the outside on in, we’re looking intently at how each component impacts another as the building is being constructed.” What’s the use of the space, and how are the walls being built? How are the spaces being separated? Are the walls being built to the deck? What are the specifics of the wall ceiling assembly? What type of ceiling tile is being specified? What are the insulation particulars? All these factors and many more, Gaus said, impact the kinetics of noise control. “Let’s say you have a workout room within a corporate environment but it’s sitting above a training room,” she said. “How can you built it to make sure that noise isn’t transferring between the spaces? Sound works like water. Anywhere there’s a leak, sound Your specialty subcontractor for acoustical will travel.

Acoustics is indeed a science. Every single room and every single building are different. Many times, we’re able to specify and procure acoustical products that integrate seamlessly into the building design.” One such example is the stretch fabric acoustical wall that Gaus Acoustics provided for the new Centene Community Ice Center in Maryland Heights, the St. Louis Blues’ new practice facility. Gaus Acoustics took the owner’s graphic design and output it on the custom acoustical fabric, material that possesses permeable, sound-absorbing cells yet is acoustically transparent to accept paint. The result is a signature element in the hockey rink’s design paired with the practical purpose of sound absorption. Kevin Tankersley is president and senior engineer of Designed Acoustics, headquartered in O’Fallon, MO. For 20 years, he has been consulting on major building projects across St. Louis. Assessments Consultations Material Procurement “There’s incredible value in bringing on an acoustical engineer at the front end Design Project Management Installations of a project,” Tankersley said. “We’ve found that owners are happier when sound issues can be prevented rather than accommodated afterward.

building has been built, we’re limited as to how we can fix those issues, and the cost is often much higher to fix them.” A straightforward acoustical analysis of the building’s project specifications, according to Tankersley, is the best means of addressing sound considerations. His firm was brought in early to consult on two new St. Louis County police buildings to weigh in on potential noise and privacy issues well before construction begins. “Our analysis includes reviewing the products specified in the building design to be sure that the frequencies will be ideal,” he said. “The sound frequency tests we perform guide the owner and project partners as to what they’ll need to be using in terms of the best product given the room conditions and function, and it guides owners are to where to invest their money.” Great acoustics, compared with good acoustics, equals absorption plus diffusion and knowing the precise amount of each, said Tankersley. “We need some of those (sound) reflections,” he said. “We don’t want to go into an office plan that’s dead. The answer isn’t to deaden everything so that anyone in the space can hear everything that’s being said. There’s a fine line in every room that an acoustical engineer needs to discover. Frequency analysis helps greatly in this discovery.” G&S Architectural Products is a longstanding, St. Louis-based manufacturer of acoustical treatments and other specialty building products. Director of Sales Dennis Voss said the ceiling is generally

the first place a building owner should look when beginning the acoustics conversation. “In the past, many commercial spaces featured lay-in tile ceilings, where now they have an open bar joist ceiling,” Voss said. “When the ceiling is open and many of the surfaces are hard, it makes for an environment in which the sound is bouncing around. This look is really cool and offers a great industrial vibe to the space, but if it’s not acoustically treated it can hamper productivity and minimize what could be a pleasant working environment.” G&S’ goal is to offer acoustical products that complement the company’s preferred office design. Voss said simple shapes with muted colors that disappear within the space but accomplish the objective of noise control are a popular choice. “Twenty years ago, most of the (acoustical) product out there was based upon the walls, such as simple wall panels,” he said. “Now, acoustical solutions have evolved into the ceiling.” One example of this product evolution are Serenade panels, a signature product manufactured by G&S. The flat, 4x4-foot, custom-shaped sounds absorbing panels hang independently from the ceiling, and all mounting hardware is embedded in

each panel’s fiberglass core to give owners a visually and acoustically attractive solution for sound absorption from above. While all of these subject-matter experts agree that front-end design alignment is the preferred time to get “sound advice,” Jenny Sturm, owner of Signature Craft, said there are many circumstances where businesses, healthcare facilities and restaurants don’t realize they need to be concerned with sound-related issues until they are already in the space – or in some cases when they are repurposing areas in their buildings. “When companies transition from individual office environments to openspace floor plans, most don’t think about the ‘knowing-everything-about-yourneighbor’ effect,” said Sturm. “Employees need to be able to make phone calls or handle private meetings in their designated workspaces without having to leave their desks and go into conference rooms. And since this frequently happens after the new design/construction phase, knowing options to correct such situations is critically important to secure the wellbeing and productivity of patrons and staff.” Be it long, noisy hallways that create echo chambers, bar spaces that distract from the desired overall diner experience

or corridors that leak noise and personal information into patient rooms, Sturm says there are numerous products that provide solutions for clients. “For instance, we often retrofit stretch fabric wall systems, like our Snap-Tex line, into existing or modified spaces to solve problems that weren’t discovered until clients started using the space or utilizing it for different purposes,” she said. “It’s especially important to modify noise problems in healthcare spaces because patient care and recovery depend upon optimal environments. “In restaurants,” Sturm added, “and this is very true for those eateries catering to multiple generations or the lunch crowd holding mid-day businesses meetings, utilizing a combination of acoustical ceiling and wall treatments – which can incorporate art or logos, therefore serving as both acoustical resources and decorative elements – can ultimately increase the restaurateur’s bottom line. After all, who wants to dine in a place where you can’t carry on a conversation, or all you hear are rambunctious children? People know the best places to enjoy leisurely meals or conduct business…and they avoid restaurants, even if the food is great, if they can’t hold a conversation there.”

Living Walls Offer Owners Opportunity to Breathe Life into Buildings By KERRY SMITH 14

CNR St. Louis Construction News and Review - www.stlouiscnr.com

Living green walls offer building owners the option of integrating a component that adds beauty and contributes to the wellbeing of their occupants and guests. Panels of plants, grown vertically via hydroponics on freestanding structures or those attached to walls, are comprised of greenery inserted into a growing medium such as lightweight soil that enables the plants to root. For owners whose goal is to maximize the beauty in a common area while occupying a minimal amount of valuable real estate, living walls afford that opportunity. “As owners are building offices, hospitals, hotels and more, real estate is at a premium,” said Roel Ventura, ambient designer for Ambius, a firm that has been designing, installing and servicing sustainable spaces since 1963. “Clients can integrate a great deal of

creativity into their living design, and we work with them to help bring that vision to life.” One example of living design here in St. Louis can be seen in the center of Terminal 1 at St. Louis Lambert International Airport, where two 15-foot-wide by 8-foot-tall living walls face each other. These walls are maintained via tray systems. The slanted trays are stacked, and 4-inch to 6-inch potted plants are slotted into holes in the trays, which are then built into the wall. “Another type of living wall system is a panel system,” said Ventura, “wherein 1-foot by 1-foot square panels with soil or a similar fibrous growing medium connects them.

The West St. Louis' lobby is an example of a local hospitality space that brings nature indoors. Living walls are gaining popularity among building owners seeking to improve indoor air quality and create a calming, more natural environment. Selection of plants and the design of vertical gardens are influenced by factors such as the existence of natural vs artificial light

is that the plants can be pre-grown in a nursery well before installation of the system.” Living design firms often work in tandem with developers and engineers because each area of expertise brings instrumental insight into an overall living wall facet of living wall project. “It’s crucial if a developer wants something of this caliber for the design and engineering of a living wall to be part of the initial build-out phase planning,” Ventura said. “Considerations such as the load weight of the wall, the system by which it is attached, whether an accompanying irrigation system is desired, and the selection of proper grow lighting are all essentials to plan for early in the building’s overall construction. Ongoing maintenance is also an important factor. When clients come to us and inquire about installing a living wall, we walk them through the process to make sure it’s a fit for them and their budget five to seven years down the road. Deciding to outsource maintenance of a living wall by a trained horticulturalist is often a wise plan for the overall longevity of the investment.”

The Westin St. Louis in downtown St. Louis is an example of Ambius’ work. The firm works with Westin hotels to select plants and lighting that promote the hospitality company’s brand, Ventura said. The lobby of Cushman & Wakefield’s downtown headquarters on Washington Avenue is another example of the firm’s work, where three 16-foot-tall by 4-footwide walls are suspended and positioned 12 inches apart to create one cohesive piece of artwork. “The interesting aspect of these walls is that they’re comprised of replica (artificial) plants,” he said. “The developer had already completed the building’s remodel but wanted to add a signature, low-maintenance feature to the lobby. We’re flexible in working with owners with various budgets and maintenance requirements.” David Blakely is sales and design specialist at Growing Green, Inc. in St. Louis, a firm founded here more than 40 years ago. The green industry leader is consulting on an increasing number of projects spanning the gamut from Class A office to healthcare to restaurants and beyond. What do these clients have in common? The desire to create and retain employees and customers with environments that are healthy and sustainable. “Humans’ innate desire is to be around nature,” said Blakely, whose firm assists companies with myriad living design components. “What architecture and construction industry leaders are realizing is that there is a huge bonus to be building these live features into spaces to foster wellbeing and productivity. “Live walls create an environment that increases creativity and satisfaction and decreases stress. Research solidly shows how biophilia translates into ROI.” According to Tracy Backus, director of sustainable programs at global office furniture designer/manufacturer Teknion, 10 percent of employee absenteeism can be attributed to a lack of access to nature. Integrating natural elements into the work environment effects an 11 percent gain in productivity, a 25 percent increase in functioning memory and a 15 percent higher level of wellbeing. “Ten years ago, the first green wall was attempted in St. Louis, but project partners specified the wrong system and it failed… so the A&D community was skeptical for some time after that,” said Blakely. “It took several years for the St. Louis community to overcome this, but now we’re seeing and

doing living wall design across the region and it’s a beautiful thing.” World Wide Technology’s global headquarters at Westport Plaza features a green wall in its lobby, evidence of Growing Green’s work. Another local project at a global operations center in O’Fallon, MO features a 20-foot by 20-foot green wall designed by Growing Green.

Green walls for lit spaces and moss walls for dark spaces present owners with an array of growing alternatives, according to Blakely. “Owners have the ability to be as creative as they envision,” he said. “We frequently design mossed logo applications and other unique, livable branding components.”

Today, concrete can be so much more than just a utilitarian material for construction. With the growing popularity of stamped, acid stained, engraved, polished, sculptured and overlaid concrete options, the utilization of this product is expanding in ways most designers and constructors never dreamed it could. Bev Garnant, executive director of the American Society of Concrete Contractors, headquartered here in St. Louis, said her organization’s Decorative Concrete Council has seen some incredible ways concrete is being used. “Today our members are more artists than simply concrete workers,” Garnant said. “We are seeing so many astonishing things ranging from unique applications of polished concrete work to statues and sculptures all around the country.

Concrete is now seen as something to be used for esthetic enhancements on projects, not just as an integral part of a structure, according to Rhett Dunlap, technical sales rep at Breckenridge Material Company. “The beauty of it is that it can be both strong and durable while being visually appealing too,” he said. Dunlap cites one of Breckenridge’s projects, the St. Louis Art Museum’s new East Building, as an example of this duality in concrete applications. “Polished dark concrete walls and the coffered concrete ceiling that provides

Mechanical contractors’ scopes of services are expanding to embrace the latest technologies and innovations in serving their clientele across St. Louis and beyond. Grant Wiegmann, director of preconstruction of St. Charles, MO-based Wiegmann Associates, said the core of his company remains central to new construction and major renovations, yet the firm’s role as an owner’s rep continues to expand the offerings in value engineering, design-build expertise, energy solutions and preventative maintenance. “Working directly for owners has given us insight on how they think,” said Wiegmann, “and it has given us better insight on the total cost of ownership. We’re able to relay that information to general contractors as we’re bidding the work. We always say that buying HVAC is not like buying flooring or drywall. There are a lot of implications for the owner down the road,” he added, noting that operational costs, comfort, reliability acoustics/ sound and controllability are part of the overall equation. Wiegmann Associates is the “M” in the MEP. As a mechanical contractor, the firm has delivered projects of up to $35 million across 42 states. Modeling buildings to anticipate what their future energy performance will be is an avenue of expertise that the company has grown into over the years. And right along with modeling is the company’s related expertise in designbuild value engineering – a service sector that has grown mightily since the firm began in 1995. “The design-build work we do is much more prevalent here in St. Louis than in other parts of the country,” Wiegmann said. “This is a very design-build market, as compared with plan-spec markets elsewhere. With design-build, an owner is essentially placing the design responsibility on the contractor. We see this as a benefit for project owners because as the firm that buys and installs the HVAC equipment, duct work and piping, we have a much keener idea of the costs than a consulting engineer normally would. We think the designbuild approach presents a much more cost-effective solution for the owner.” Performing analyses of HVAC and lighting systems to guide owners into applying for Ameren rebates is another service area that Wiegmann Associates has grown in recent years. “If we don’t initiate (the rebate application), a lot of times it doesn’t happen because the owner is not aware of the opportunity,” he said. “Speaking of a lighting system, it’s more of a prescriptive rebate whereas an HVAC system rebate is more customized, requiring detailed calculations. We include this analysis in our cost estimate, so the owner doesn’t have to hire an energy consultant to provide it.” Mark Bengard, senior vice president of sales and preconstruction at Murphy Company, said this mechanical contractor with a 100-plus-year history continues to expand not only in expertise and services but also geographically. The firm’s headquarters is in St. Louis and it currently has four regional offices in Colorado. “We’ve been expanding to meet customers’ demands,” Bengard said. “We will travel with clients as they continue to grow.” Data centers are a true service category that Murphy Company has grown significantly over the past few years, according to Bengard. Calls come to the firm’s dispatch headquarters in

St. Louis and a team is dispatched to nearly 80 data centers across the country, all maintained by Murphy Company. “That was a true expanding need,” he said. “We already have Data Center Services as an established provider, but some of our key clients required multiple data centers as the backbone of their operations. We’re constantly building new data centers for our big clients and we also maintain them. These systems automate and back up data for A/C controls, HVAC controls and related equipment that supports all of a company’s IT systems.” Designing temperature controls for HVAC and plumbing systems is another category of service offering that Murphy Company finds itself growing to meet demand. “Lean construction and the reinforced practice of teamwork across all specialties is what enables us to continue expanding what we provide,” Bengard said. “The whole team – the GC, electrical contractor and mechanical contractor are working together on complex commercial, industrial and institutional systems for the benefit of all. Particularly on some of the large, centralized systems at plants such as the chillers and boilers, it’s often

less expensive if the owner does not build a wall until all our equipment is in place. Lean construction brings all that to the forefront,” he said, adding that the new SSM Health SLU Hospital, scheduled to reach completion in 2020, is an example of where Murphy Company performed a significant amount of systems prefabrication in the firm’s shops, utilizing CAD/CAM and working in tandem with the GC and the project’s electrical contractor. “We’re getting away from all the silos,” he said. Murphy Company, too, is a Certified Energy Manager, evaluating complex lighting and energy systems for large clients. The company is an Ameren Partner for the energy efficiency incentives and as such has obtained incentives of more than $600,000 for its customers. Over the past five years, Kirkwood, MO-based Rock Hill Mechanical Corporation has rebuilt its engineering and building information modeling (BIM) department to be one of the largest in the market, according to Jamison Bloebaum, professional engineer and vice president. “We’re the only local (mechanical) contractor that is doing all the BIM

coordination and the spooling entirely within Revit,” Bloebaum said, noting that spooling is taking the drawings and putting together all the parts and pieces into an 3D model (via Revit software) with a detailed bill of materials and installation documentation for assembly of the duct work, piping and fabrication. “Our approach is unique in that because, unlike other contactors, we don’t begin the process in Revit, transfer it into AutoCAD and then pull it back into Revit. There’s a data loss risk in transferring between platforms. When we deliver an as-built drawing we also have an as-built model that has been in the same format from beginning to end, ensuring it is accurate and zero data has been lost.” Pursuing more design-build and designassist projects are other examples of how Rock Hill is evolving over time. Bloebaum said the firm is completing more designassist projects in which it is performing a lot of the systems engineering work in tandem with a mechanical engineering consulting firm. Tim Decker is president of Bridgeton, MO-based C&R Mechanical Company and current board president of the Mechanical Contractors Association of Eastern Missouri. Decker said his industry and related industries are adapting and investing a tremendous amount of capital in people, hardware and software. “With the advent of BIM and the 3D coordination required in our business, the expectations from our clients have also grown tremendously,” Decker said. “The investment in all this technology has definitely increased our business. We’re able to be more efficient with our design and installation.” In addition to 3D modeling software, field hardware and tools that take the Revit data and transfer it remotely to construction workers on project sites is also expanding in leaps and bounds. “Everything that is produced in the 3D world has to be transferred to those who need to access it to build,” Decker said. “Tools that appear as a surveying tripod are being used to pinpoint each hanger location, each floor penetration and precisely where every access point needs to connect to the (system) structure. We’re continually investing time up front to build the virtual model so it’s an exact fit when we get to the field,” he added. Offering owners the opportunity to don virtual reality goggles to “walk” through the space before it has been

constructed is part of C&R’s service offering that has grown increasingly more widespread among clients who are able to request changes well before any building has taken place. “An owner can literally walk through (virtually) where the ductwork, piping and equipment is located,” said Decker. “If it’s a hospital client, for example, the owner can see the connections for all the intricate mechanical systems, including all the specialty medical gas systems and more.” Greg Harty is director of sales and marketing for Charles E.

This area of our service offerings has grown materially due to the commercial and industrial demand for efficient, environmentally friendly operations control. When a company has estimating, engineering, CAD, BIM, controls, energy, management, project management, accounting, prefabrication facilities, construction labor and service/ maintenance all under one roof, it allows for a lot of vertical integration, streamlining, efficiency and reduction in fees.”

Building a two-story, 120,000-square-foot aquarium within a National Historic Landmark structure dating back to 1894 is replete with design and construction challenges that project partners continue to meet head-on and creatively solve as they prepare for December’s public opening of St. Louis’ indoor aquatic wonderland. Lodging Hospitality Management (LHM), owner of St. Louis Union Station, is also the owner of St. Louis Aquarium. Construction manager McCarthy Building Companies, paired with attraction designer and master planner PGAV Destinations, have been working with a team of specialty subcontractors and local trades since the project’s start in November 2017 to deliver a world-class family destination that is expected to draw more than one million visitors annually. “This is definitely a new adventure for us,” said Chad Smith, vice president of design and construction for LHM. “We bought Union Station in 2012 and are continuing to transform this 30-plus-acre development.

Key construction phases of St. Louis Aquarium included: structural work of

evaluated the possibility of building all new (aquarium) construction rather than fitting the St. Louis Aquarium within Union Station, but we’re passionate about the rich history of this landmark. Being able to stand in the aquarium, look up and see a 125-year-old structure above you is priceless. We’re committed to providing that level of experience to visitors, incorporating St. Louis’ unique train and river legacy in the process.” Initial interior demolition in order to open the space for aquarium construction presented a formidable challenge early on, according to McCarthy Project Manager Shawn Brinker. Leaving the historic infrastructure of the original 1894 train shed intact as a Landmark-designated property, controlling noise and dust while working close to the operational 567room hotel and adjacent restaurants, and working from “as-built” drawings created more than a century ago all contributed to the complexity of the work. “We had limited access to certain areas, sometimes affording us as little as a few inches of space, as we worked to protect and preserve original columns, footings, foundation, underground piping and more,” said Brinker. Geotechnology’s purview was front-end engineering and geotechnical evaluation of subsurface conditions prior to the design and installation of structural support systems for the aquarium. “The Union Station property has a lot of geotechnical history dating back to the 1850s,” said Tony Roth, project manager and geotechnical engineer for Geotechnology. “Most of Union Station including the aquarium site was built over Chouteau’s Pond. The nearly 30-foot-deep pond was drained back in the 1850s, some 40 years prior to the construction of Union Station, when foundations for the train shed were then built. Additional foundation systems were built in the 1980s to support the mall. We had maps to indicate details associated with the stacked limestone footings and timber pile foundations underneath the train shed – and the 50-foot-deep driven concrete piles that supported the mall – but the creative challenge was working with PGAV Destinations’ design team to increase loading capacities for the mall’s foundation to support features of the aquarium. Reusing some of the existing foundations while installing additional micropile systems around them became the ideal solution,” Roth added, noting that

the aquarium project denotes the third iteration of the classic structure over the past 125 years. During geotechnical exploration, one remaining tenant operating in the food court of the mall required additional project considerations specific to venting drill rig exhaust fumes, according to Roth. The process was complicated by the existing maze of halls and corridors on what would become the aquarium’s lower level. Direct push sampling using a dynamically driven tube sampler paired with manual auger borings were techniques Geotechnology employed within the historic structure’s tight space constraints. Jeff Klein, principal engineer in Geotechnology’s materials testing group, said the firm was tasked with special inspections, construction observation and materials testing. “We also employed concrete scanning to locate reinforcing in the existing concrete, which allowed the contractor to make perforations through existing concrete without damaging the existing reinforcing steel,” said Klein. The testing encompassed the foundations, soil, concrete and structural steel for the project, with team member ABNA Engineering providing some of the concrete testing. Hunt Vac Services served as a subcontractor to McCarthy on the interior demolition of the retail spaces that had been home to shops and restaurants. Susan Hunt and Project Manager Jevon Poncez said the demo spanned two phases. The initial phase was a soft, non-structural demolition removing everything from floor to ceiling. Phase two was more structural in nature, taking out concrete on the first and second levels and removing the HVAC system from the third level. “For Hunt Vac, this is the largest interior demolition project we’ve taken on,” said Hunt. Helitech Civil Construction installed the deep foundation micropile system capable of supporting exceptionally heavy loads driven by the water-filled exhibits and back-of-house animal life support systems. The system designed for the aquarium includes capabilities to support shear and compression loading. “There are huge weight issues to contend with in terms of the loading requirements of aquariums,” said Jason Courtney, president of Helitech. “The system we engineered and built allows for that capacity amidst a lot of

space limitations and overhead height limitations. Most of our micropiles are designed to hold between 70,000-150,000 pounds per pile, and we installed in excess of 200 piles on this job,” he added, “supporting more than 20 million pounds of structure in all.” Installing a micropile system, Courtney noted, eliminates the need to bring large drilling equipment onto a site, complying with historical landmark requirements and enabling support structures to be built within tight spaces. The micropiles installed at St. Louis Aquarium are supporting the exhibits, river gallery, ocean gallery mechanical pump rooms and other front and back-of-house systems.

Waterhout Construction supplied and installed the wood blocking, hollow metal and wood doors, hollow metal frames, door hardware, custom millwork/casework, expansion joints, exterior benches, fences, restroom partitions and more for the aquarium project. Waterhout Vice President Jeff Bunge said the firm also supplied and installed fiberglass catwalks around the shark exhibit and other exhibits. The contractor also supplied and installed reclaimed barn siding from San Francisco for the Bait Shop, where visitors may acquire food to feed the aquatic animals. Bunge added that the St. Louis – Kansas City Carpenters Regional Council assisted Waterhout in the work.

“Anytime you add an animal to the equation, you add a biological element. Mechanical, chemical and biological filtration are layered to achieve the best possible conditions for the animals. A total of 17 independent systems at the St. Louis Aquarium are each tailored to support the particular animal in each exhibit.” Rock Hill Mechanical performed the HVAC piping and ductwork that will heat and cool the facility. Jamison Bloebaum, vice president, said supplementing the installation workforce of Longhorn Organics – the Forney, TX-based firm specializing in animal life support systems – was also a major aspect of the work that the local MEP contractor performed. Creating and delivering customized animal life support systems (LSS) is Longhorn Organics’ specialty. Co-Owner Holly Dempsey said the firm provides water filtration and infrastructure systems for aquariums, zoos and theme parks.

Animal life support systems are similar in scope to human aquatic systems such as those designed for swimming pools, she said, and yet the layered, sequenced systems that support animals are decidedly more complex. “Anytime you add an animal to the equation, you add a biological element,” said Dempsey. “Mechanical, chemical and biological filtration are layered to achieve the best possible conditions for the animals,” she added, noting that the St. Louis Aquarium LSS are designed to accommodate animals that live in rivers, oceans, freshwater and saltwater. “A total

of 17 independent systems at the St. Louis Aquarium are each tailored to support the particular animal in each exhibit,” she said. For the touch tanks wherein visitors are able to interact with species, Longhorn Organics prebuilt a skid filtration system on a mounted platform for a single point of contact and an on/off button allowing staff flexibility if they decide to change out the specific species of animal at any given time. The system also features easily interchangeable components. Examples of system components, both in the public exhibits and in the back of the house, are separate holding tanks, quarantine tanks, piping to provide individualized, treated water to each unique exhibit of animal life, ozone and temperature control systems. Working directly for LHM, Longhorn Organics began as a project partner during the excavation phase. Most of the pipelines connecting the LSS are underground, Dempsey said. Underground systems work took nearly eight months as high-density polyethylene – a material with a longer life than PVC – was welded and fused together. “Our pipe size ranged from two-inch up to 24-inch,” she said, noting that the flow rate for each exhibit dictated the size of piping. More than 10,000 linear feet of pipe was

built for the aquarium. The five back-ofhouse basins alone hold 100,000 gallons of water. Both mechanical and chemical layers of filtration systems were engineered and built. Large sand filters measuring 96 inches tall and several feet in diameter were installed by Longhorn Organics, each with varying layers of gravel and sand. Dempsey said on-site machines are producing ozone gas as an animalfriendly means of chemical filtration rather than chlorine. The aquarium’s biological filtration system introduces the right strains of bacteria to promote animal health. “They’re the soldiers who are doing the real work,” she said. Local Union 562 Plumbers & Pipefitters, under the direction of Rock Hill Mechanical, assisted the firm in construction of the systems. The Companies of Nassal is the project’s scenic fabricator for all the artificial rock work both in and beyond the exhibits that visitors will appreciate at St. Louis Aquarium.

McCarthy self-performed much of the aquatic concrete work for the exhibits, carefully maneuvering between existing, 120-yearold concrete columns to create habitats for the abundance of aquatic life that will now inhabit the historic former train station. A total of 1,145 cubic yards of aquatic concrete was needed as a critical component in the walls of each fish habitat. The pressure per square inch of aquatic concrete is typically 6,000 psi compared with standard concrete that has a psi of 4,000.

A 14-foot-tall clock tank that holds 10,500 gallons of water and numerous colorful discus fish indigenous to South America serves as a dramatic entry to St. Louis Aquarium. The fish species, also known as symphysodon, is a genus of cichlids native to the Amazon river basin. Due to their distinctive shape, behavior, bright colors and patterns, discus are popular freshwater aquarium fish. Once open in late December, St. Louis Aquarium's operating hours will be 10am to 6pm. Hours during holidays and special events will vary. General admission tickets allow access to the aquarium and to programs within its exhibits and galleries. Tickets to The St. Louis Wheel, the ropes course, miniature golf course and mirror maze may be purchased separately. Guests are also able to purchase combination passes to multiple venues at a discounted price.

animals,” said Ohlsen. “Secondly, they need to enhance the visitor experience. The rock work in this aquarium is very stout at 5,000 pounds per square inch, and concrete tanks are built to an even higher standard than that.” Nassal employed a custom concrete mix design that met both the structural and artist needs of the client. Breckenridge Material Company supplied the aquatic concrete mix for the aquarium exhibits. Ryan Bohon, director of sales with Breckenridge, said the mix included antimicrobial and moisturemitigating admixtures. The subcontractor worked in tandem with Vee-Jay Cement Contracting Company in pouring more than 2,200 cubic yards of concrete and alongside McCarthy, pouring another 1,800-plus cubic yards, much of it aquatic concrete. Local trades including Ironworkers Local 396, Plasterers’ Local 3 and Painters District Council 58 worked alongside Nassal on pivotal tasks. One formidable task, according to Ohlsen, was

delivering and applying shotcrete – sprayed concrete – through a hose from a longer-than-usual distance. “The closest we could park our (concrete) trucks was along 18th Street, which was several hundred feet from where the shotcrete needed to be applied,” he said, noting that a lane of traffic on 18th Street at Market Street had to be blocked off from traffic for a full day, with a series of trucks arriving every 35 minutes to convey their loads through a hose that stretched 300 feet from the curb to the project site within the aquarium. “The logistics of pumping exact mixtures and pneumatically projecting it at a high velocity onto the surface, as a half dozen sculptors directly followed the concrete teams and molded the product into place, was an unusual challenge,” said Ohlsen. PGAV Destinations Architectural Designer Andrew Schumacher said the firm worked closely with owner LHM and construction

manager McCarthy to meet the goals associated with theming of the exhibits and overall historical significance of the destination. “Part of the whole concept of working within a historic train station was to really play up that story,” Schumacher said. “Not only will visitors experience a first-class aquarium, they’ll do so via the lens of historic train travel. Visually we’ve worked hard to mimic the city’s rootedness in train transportation and to overlay St. Louis’ significant river history.” As visitors enter the aquarium lobby, they’ll behold a 14-foot-tall clock tank holding 10,500 gallons of water and a collection of colorful discus fish native to South America. Arched ceilings will add to guests’ sensation that they’re embarking on a train journey, especially as their ticket (which includes a specific “boarding” time) is called out and they enter simulated, life-size train cars to begin their tour of the aquarium. Exhibits include the Mississippi-Missouri River – complete with an enormous underwater tree made of sculpted shotcrete. “Once you set off on your train journey, you immediately gain the sense that you’re at the bottom of the river,” said Schumacher. “One thing about this project that is truly unique is that we did all of our rock work design on a computer. A computer program known as Zbrush allowed us to virtually sculpt and model, similar to how we used to model in clay. We were able to bring it all into BIM, edit it and were then able to 3D print it to see it in the field and bend the rebar to hold the rock work. This method enabled us to create precise models in order to coordinate with the custom acrylic (exhibit-viewing) panels that were fitted into the aquatic concrete.”

“The design and construction of this exhibit makes it appear to be the ruins of a South American temple. This exhibit will house enormous fish that hail from South American rivers and lakes.”

River Monster is another exhibit that will entertain aquarium goers, according to Brinker. “The design and construction of this exhibit makes it appear to be the ruins of a South American temple,” he said. “This exhibit will house enormous fish that hail from South American rivers and lakes.” Visitors will then move on to behold the nearby piranha exhibit. No doubt one of the most talkedabout experiences, Brinker said, will be negotiating the ramp running to the side and underneath the 250,000-gallon, exhibit known as Shark Canyon, which will include 60 sharks and rays. The walk

leads visitors down below the tank (18 feet, 6 inches deep at its deepest point), where they’ll be able to gaze straight ahead and upward as schools of sharks swim directly over their heads. Installing the oversized, curved acrylic panels into place within a tight space prior to the concrete walls being poured required precise, detailed measurements. Height and sound restrictions also played a role in the complexity, as the exhibit is located directly below and adjacent to hotel rooms. Designing and building access to and from each of the animal exhibits was critical, allowing staff to feed, shelter and

What Is Success?

Before we start any project, we ask ourselves the question, “What does success on this project look like?” Two epiphanies evolve from that question: 1.) We realize that success, whether that’s a satisfied customer or meeting a tough deadline, is a process, not a destination. 2.) We recognize that we need to savor, and applaud the smaller victories of our team along the way, as well as acknowledging shortfalls and acting to improve the process. It’s human nature to believe we’ll be more successful later than we are at any given moment. We should always be growing and trying to be better than we were before. Tony Robbins calls it CANI: Constant And Never-ending Improvement. At Drilling Service, we’ll celebrate all our team’s successes in 2018 – not just the big ones. As always, we’ll own and learn from our mistakes and have the courage to try new things. Our future and that of our customers, depends on it. Number two in “Murphys’ Laws,” the creed under which we operate is: “Plan for success before we ever set foot on the job.”

St. Louis Aquarium visitors will behold a 250,000-gallon shark habitat, Shark Canyon, that includes 60 sharks and rays. The exhibit will also serve as a backdrop for private and special event space. Some 53,000 pounds of permanent acrylic panels equivalent to 1,552 square feet have been utilized in various exhibits throughout the aquarium, much of it in conjunction with this exhibit. Panels ranging from 3 feet by 3 feet up to 16 feet by 18 feet required long materials lead times as well as precise installation. Building the aquatic life in St. Louis from accredited zoos and aquariums, rescue facilities and additional organizations that follow sustainable sourcing practices is a top priority.

interact with the aquatic wildlife and to clean the habitat spaces, Schumacher and Brinker said. Several of the exhibits span more than one level, adding to the beauty but also the construction complexity. The upper level of the St. Louis Aquarium plays host to an above-waterviewing otter exhibit, a waterfall feature, several touch tanks, laboratory space, veterinarian quarters, the Bait Shop, kitchens where animal food will be prepared, a power generator and more. McCarthy self-performed much of the aquatic concrete work, according to Brinker, who said the strength of aquatic concrete is typically in the range of 6,000 pounds per square inch, as compared with standard concrete that has a psi of 4,000. “Working with 120-year-old concrete columns and elevating the (second-story) deck so we could successfully place the concrete without affecting these existing train shed columns was a hefty construction challenge,” he said. “Utilizing cranes and lifts with serious overhead restrictions was another related obstacle that we needed to surpass.” Hydrotesting the animal exhibits with water to ensure that the pH, oxygen level, temperature and other conditions are exactly as they need to be for each species of animal life – was a vital aspect of the project. Caring for the 13,000 aquatic creatures who will live in the St. Louis Aquarium, as well as overseeing all operations of the new destination, is San Francisco-based zoOceanarium Group. Founder and CEO Chris Davis’ company operates aquariums, dolphinariums and zoos worldwide. “LHM brought us into this project at an early stage so we could collaborate with PGAV Destinations to create a top-notch destination that cares for the well-being of each aquatic animal and provides an exceptional visitor experience, too,” Davis said. “A lot of times, aquariums are built without the operators in mind. Not so in this situation. LHM invested generously on the front end and had the vision to enable the collaboration of design, construction and operation that has been taking place for two years. There are nuances along the way where the operations side can provide input into design and construction to make the end product the very best for the animals and for the guests. We’ve been able to do that here.” St. Louis Aquarium will employ approximately 90 full-time and part-time

staff members who are directly involved with aquarium operations, according to Davis, and another 30 to 50 workers staffing the destination overall. An animal care staff includes a cadre of veterinarians as consultants, a curator, on-site biologists and weekly visits from a dedicated aquatic veterinarian who will receive daily records on each animal. In addition to the aquarium, zoOceanarium is the operator for the facility’s indoor ropes course and mirror maze.

Construction Workforce 2030: Who Will We See Working? What Technologies Will They Be Leveraging? By KERRY SMITH


CNR St. Louis Construction News and Review - www.stlouiscnr.com

When construction owners visit the jobsites of their projects in 2030, who will they see working? The year 2030 sounds far away, but it’s only a decade hence. Here are what construction industry leaders are predicting:

Brian Turmail, Vice President of Public Affairs & Strategic Initiatives, AGC of America: Second-generation exoskeletons – battery-charged robotic suits that allow workers to hydraulically lift and manipulate up to 200 pounds – will likely dominate the jobsite, enabling workers to remain in physically demanding jobs for longer periods of time. Exoskeletons will allow craft workers to do more safely than they can today with less risk of injury and fatigue. Other robotics that will be even more commonplace on jobsites in 2030 include bricklaying and rebar-tying robotics. RFID (radio-frequency identification) microchips that craft workers wear on their equipment will continue to be used to ensure productivity on the jobsite and promote more methodical use of labor such as the organization of tools at the jobsite. Because there will be a lot more technology at a project site and a lot more innovation, workers are as likely to have an iPad attached to their belt as they will a hammer.

Frank Jacobs, Business Manager, IBEW Local 1: The construction workforce in 2030 will be more diverse than ever before. Right now, our workforce is comprised of 19 percent

minorities. Since 2011, our incoming workforce has averaged 25.8 percent minorities, and it’s most attributable to an increase in females and African Americans. We predict that this increase in diversity will continue, which will increase our numbers to meet the diversity needs of the industry. Prefabrication propelled by continual advancements in BIM (building information modeling) will continue paving the way for expediting projects and working year-round. Most of our larger contractors have prefab shops at their warehouses already. By 2030, many tradespeople will be working in climate-controlled prefab environments and even more assembly will be taking place long before the components reach the jobsite. The precise location of each component will be pinpointed prior to materials ever arriving onsite.

Al Bond, Secretary-Treasurer, St. Louis – Kansas City Carpenters Regional Council: Fast-tracking building construction is here to stay and expand. Ten years from now, there will be fewer people working on the jobsite because they’ll be working in the prefab shop. Most everything will be 3D modeled. We’ll all continue to be doing more with less, with lean teams working 12 months out of the year, thanks to controlled environments. More and more women and minorities will replace the baby boomers who’ve retired. The future workforce’s command of rapidly evolving building technology will demand those with a fierce work ethic who are committed to a career that provides exceptional pay, benefits and ongoing educational opportunities for them and their families.

Dave Gralike, Missouri Branch President, Guarantee Electrical: Ten years from now, the youngest baby boomer is going to be 65. That whole bubble of available workforce is going to be out of the industry and will have to be replaced. No doubt, a total renaissance of technology will drive the industry to take a completely different approach to work. We’re predicting that every construction project will be fully modeled and sent to contractors for pricing. A fully modeled project not only provides a fully engineered product, it also identifies the exact footage of every conduit, wire type, distribution, etc. The components of the job will be detailed down to connectors and locknuts. This means that every contractor will be working from the same design and takeoff. This new delivery method mitigates the advantages of contractors that have robust design, modeling and estimating capabilities. Only the specialty contractors most proficient in building efficiently will survive.

A S S O C I AT I O N S The Illinois Dept. of Transportation Last Mile Infrastructure Project at America’s Central Port is on track to be the first project completed under the new competitive freight grant program. Federally funded, the Illinois Competitive Freight Grant Program marks the first time in Illinois' history that funds have been specifically designated for freight projects. This IDOT program, which required a 10 percent to 20 percent funding match on the part of the awardee, has awarded a total of $245 million in grants for 23 projects in program years 2018-2022. These projects include roadway reconstruction, grade separation, intermodal infrastructure, port improvements, technology deployment, truck parking and interchange construction. With materials libraries dwindling in design firm offices across the St. Louis metro area, a local chapter of The American Institute of Architects is opening the doors on an all-new resource to supply designers with a plethora of materials and space to plan and interact with those who rep them. A dedicated team of eight at AIA St. Louis has been working for three years to build out and supply the Resource Center, located at 911 Washington Avenue downtown, adjacent to the AIA’s existing bookstore and offices. AIA St. Louis 2019 Board President Lucy Williams, herself a licensed architect and firm owner, has helped spearhead the effort. The 1,800-squarefoot center is managed full-time by David Charles, according to AIA St. Louis Executive Director Michelle Swatek, and is now open from 9am-4pm Monday through Friday. While the center is also open to non-AIA St. Louis members, members will have additional access to the space. Students in three Saint Louis Public Schools are benefiting from the next generation of lighting designed to improve outcomes in classes and athletics. The SHINE STL installation is a unique pilot


program sponsored by the Electrical Connection, St. Louis Cardinals and Cardinals Care, PLANLED and the Saint Louis Public Schools Foundation. SHINE STL introduced higher quality LED human-centric lighting to a computer lab at Lyon Academy, the gymnasium at Gateway Elementary and the multi-purpose room at Gateway Michael schools. A welding teacher from Sikeston, MO has won first place in the 2019 Harbor Freight Tools for Schools Prize for Teaching Excellence, earning his high school skilled trades program $70,000 as part of $1 million awarded nationally. Brent Trankler, who teaches welding at Sikeston Career and Technology Center in Sikeston, was surprised in his classroom by a representative from Harbor Freight Tools for Schools with the news that he and his school will receive $100,000, $70,000 for the school’s skilled trades program and $30,000 for Trankler. The Kwame Foundation raised more than $50,000 at its 16th Annual Golf Tournament at Top Golf in Chesterfield, MO. Proceeds will fund scholarships for first-generation, collegebound students at Washington University, Maryville University, Saint Louis University and the University of Kansas and several other higher education institutions. The St. Louis Council of Construction Consumers hosted its annual Owner's Roundtable Event to offer the professional construction community an opportunity to have face-toface interactive discussions with owners on 21 different topics relating to best practices in project delivery. The group also discussed projects on the horizon in 2020 and beyond. A new Hoyt Advisory Services Study commissioned by the National Apartment Association and National Multifamily Housing Council reveals that the apartment industry and its residents annually contribute $18 billion to the St. Louis

metro economy, $38.4 billion to Missouri’s economy and more than $3.4 trillion – or $9.3 billion daily – to the national economy. The new report, available at WeAreApartments. org, provides a detailed breakdown of the economic impact nationally, by state and in 50 metro areas. In St. Louis, the apartment industry supports 96,358 jobs. Other financial contributions break down as follows: resident spending contributes $16.1 billion to the local economy, operations add $780 million, new construction contributes $810 million and renovation and repair add $320 million. On behalf of the Home Builders Charitable Foundation, 2019 HBA President John Suelthaus (Kingbridge Homes) and HBA Executive Vice President Celeste Rueter presented a $15,000 donation to Deirdre Schaneman, resource development operations manager for Habitat for Humanity Saint Louis. The donation will be used to support Habitat for Humanity Saint Louis’ 2019 build program. The funding will play an integral role in helping HFHSL reach its goal of building 10 new homes in the La Saison neighborhood. Once the homes are completed, they will be purchased by hardworking, low-income families who will each perform 350 hours of sweat equity to qualify for their purchase and assume a 30-year, affordable mortgage payment. The HBA is a local trade association of more than 600 member firms representing the residential construction industry. The Herculaneum High School Black Cats saluted the Electrical Connection for donating a new scoreboard to enliven football games.

Change for Change’s Sake: With Technology, Is Newer, Faster and Fluffier Better? Change for change’s sake – or should I say tech for tech’s sake? The more I mulled over my last column (the one about having dinner with a real live rocket scientist) the more I realized I hit on one of many symptoms of the problem the tech industry has in dealing with customers. It’s no wonder most people dislike dealing with technology. First off, most in our industry don’t even call you customers or clients anymore. You’re now an end user. Catchy, isn’t it? In the eyes of the manufacturers and designers, what you the customer want really isn’t important. It’s all about what they see fit to drop on your plate. Like that last column when I wrote of how much useful data was gleaned about Mars from a download speed that would make the average teenager go into a meltdown over its slowness, we’re bombarded with garbage through our cable, fiber or DSL lines, all taking up useful space and making us wait for the useful stuff. Fast forward to very recently. After about five years, I finally replaced the PC on my desk. I really must raise my energy and courage whenever I replace my primary machine since no matter how easy the industry tells all of us it is, it often winds up being a 20- to 30-hour project. And so it was again. Transferring the documents and data aren’t the problem anymore. It’s having to reinstall each application, then configure it. I’m close to the last person to use a new technology for myself, since most of our clients are small businesses. I need to see what they see, and most prefer to stay away from the bleeding edge of technology and wait until proven benefits are shown. Not to say I don’t learn the new things. I spend about 10 hours a week just keeping up with product announcements and updates, but as someone who’s dealt with tech for more than 40 years, I don’t want to be constantly fiddling with my own. I just want it to get the job done for me. Now that I have Windows 10 on my primary machine, I become more irritated by the day. Microsoft, just like Apple and all the others it seems, has decided that those who pay for the products shouldn’t be able to use them as they’d like – only as the makers envision. Thus Windows 10, for all the new things it can do, is now very much like a Mac in that all the customization has been removed. Stupid little things like changing the icon title size or font, spacing or increasing the size of text inside a program but not on the desktop have become tedious to accomplish. You can’t remove Word or Excel, even if you use competing products. And setting up a machine without creating a Microsoft account (can you say Big Brother?) takes some fancy work. On the tech discussion boards, the Microsoft techs are

instructing people to load third-party tools to hack into Windows to make even the most cosmetic changes which used to be a menu away. Macs have always been that way, paraphrasing the Henry Ford quote, “You can have it any way you want as long as it’s our way,” but now Windows is the same, much like Adobe, that has tried to push its pay-by-the-month cloud for years now. We see this dumbing down happening in all facets of technology. Automobiles now become more irritating each second, reminding us that our seatbelt is not attached (even if we’re driving five miles per hour down our driveway). Aircraft pilots now need more simulator time. Because automation is so prevalent in the cockpit, it’s feared pilots have lost their edge when they need to take manual control in an emergency. With good old Windows, the settings page now takes the entire screen to present all of 14 items instead of the dozens of options we used to have. As for icons, we’ve gone back in time to hieroglyphics since it seems the designers don’t think you can read. We no longer tape record any show we want on TV as we gave up the old VCR in the name of progress. We’re now stuck with DVRs which can’t permanently save anything. Please remind me which icon means high beams and which is for running lights. This constant push for faster internet connections, bigger screens to show larger icons (which accomplish less with each version) and exponential increases in the use of storage space (both locally and in the cloud) aren’t really bringing us any meaningful increases in productivity, are they? Do you get more done at your computer now than five or 10 years ago? Or are you presented with more fluff and junk using up the productivity gains from newer technology? Not sure what the answer is, but more and more of us are keeping our gadgets longer and longer, so maybe there’s hope. Be sure that when your business is told it’s time to upgrade, update or replace technology that there is a compelling reason and productivity benefit. If not, perhaps it’s time to look at technology from another perspective.
