The California Department of Transportation (Caltrans) began a major project on the 60 Freeway July 22 to repair deteriorated pavement slabs from Euclid Avenue in Ontario to the 60/91/215 freeways junction in Riverside. Caltrans is also about to begin a bridge replacement project this fall that will replace Pipeline Avenue, Monte Vista Avenue and Benson Avenue bridge structures on the 60 Freeway.

These projects, along with other local interchange jobs have been dubbed the “60 Swarm” as a reference to the long stretch of work going on over the next two years on this freeway from Chino to downtown Riverside.

Caltrans awarded the concrete removal and paving portion of this nearly $135 million project to J. McLoughlin Engineering, Inc. out of Rancho Cucamonga. Most all of J. McLoughlin Engineering’s work is for Caltrans, and on this particular project they are performing the freeway concrete slab removal and replacement for traffic lanes and shoulders, along with upgrading pedestrian sidewalk ADA ramps and rehabilitating all of the on and off ramps over a 9-mile stretch of work on both the State Route 60 east and westbound lanes. As a part of this project, Sema Construction of Riverside will replace three bridges along SR-60 at Pipeline Avenue, Monte Vista Avenue and Benson Avenue at the cost of approximately $23 million.

Their work began a few weeks ago and is being completed during nighttime freeway closures over 18 months.

J. McLoughlin Engineering officially began work on the 60-rehabilitation project July 22 and are scheduled to have everything complete by June 2022. Caltrans began multiple projects in July 2019 to improve safety, traffic flow and ride quality for motorists on State Route 60. Most of the concrete rehabilitation work is being done over a 55-hour weekend schedule, beginning Friday nights at 10 p.m. and ending Monday mornings at 5 a.m. The construction will last into November 2019 with the duration of the project performed through the use of conventional lane closures.

According to reports, the full closures are allowing the project to proceed at twice the speed of the standard partial lane closure methodology.

The project is being funded,

in part, with $16.9 million from the Senate Bill 1 (SB 1), also known as the Road Repair and Accountability Act of 2017.

Joe McLoughlin is the president and owner of J. McLoughlin Engineering, Inc. and he has been doing work for Caltrans over his entire career. In 1991, he decided to go on his own with an initial $40,000 project, and it all grew exponentially from those humble beginnings. This State Route 60 rehabilitation project is one of the largest and most high-profile jobs that J. McLoughlin Engineering has performed for Caltrans in their 28-year history. “This is a good job for us, and we are tasked with replacing the three and four lanes for a nine-mile stretch on both the east and westbound lanes of the 60 Freeway,” says McLoughlin.

Above Right: Wirtgen TCM 180i flexible secondary texture curing machine from Nixon-Egli Equipment Co. uses automatic spraying and tining broom system to protect pavement from drying out and cracking.

“Our goal is to pave a mile of 12foot lane in a 55-hour weekend.”

To meet this goal, J. McLoughlin Engineering crews will remove the existing concrete section, excavate down to 30 inches in depth, and then install 8 inches of aggregate base, 6 inches of lean concrete and 16 inches of concrete pavement. The newly paved concrete will then need to cure for 10 hours before opening to traffic by 5 a.m. Monday morning.

Joe McLoughlin estimates that they will utilize approximately 120,000 cubic yards of aggregate base, 60,000 cubic yards of lean concrete base, and 250,000 cubic yards of concrete 8

pavement. “At the peak of construction, we have around 30 individuals working on the job site each weekend. This includes an excavation crew, lean concrete crew, and a concrete slab crew,” says McLoughlin.

The crews are supported by four excavators, around 40 semi end dumps and two Wirtgen paving machines. “We recently purchased a Wirtgen SP 94i inset slipform paver and a Wirtgen TCM 180i texture curing machine from NixonEgli Equipment Co. and these two machines are performing beautifully for us on this project.”

The Wirtgen SP 94i inset slipform paver begins by paving

CON C RETE CO NS TRU CT I O N / 2 0 1 9

the concrete section, and it is then followed directly by the Wirgen TCM 180i flexible secondary texture curing machine designed for large concrete pavers. The newly placed concrete must be protected without delay to prevent drying out, as this can cause shrinkage, leading to cracks forming in the new concrete surface. The Wirtgen dual function TCM 180i is a four track self-propelled tine/ cure unit that follows behind the slipform paver and equipped with both an automated tining system to produce the desired pavement surface macro texture { Continued on page 10 } C A LCO N T R AC TO R .CO M

and an automatic spray system for application of the curing compound to the freshly paved concrete to assist in concrete hydration. The TCM 180i is capable of accepting a range of various cure compounds, and can be set up for longitudinal or transverse texturing, and the modular frame design allows for paving widths from 14 feet to 60 feet.

The state-of-the-art Wirtgen SP 94i is a Tier 4F compliant, fully modular four track slipform paver for paving widths from six to 31 feet. It is equipped with Smart Steer and 90 degree track steer for enhanced jobsite versatility, hydraulic leg swing for ease and speed in changing configuration from paving to transport, the 1300wi mold system complete 10

with spreader plow/grout box auger combination and the new Wirtgen automated dowel bar insertion (DBI) system which allows for automatic insertion of tranverse dowel bars into the pavement on-the-go. “Both of these Wirtgen machines have been an invaluable investment to us, especially on this high-profile State Route 60 project,” says McLoughlin. “We purchased these machines through NixonEgli Equipment Co. and our representative, Jay Rosa, and the entire staff at Nixon-Egli and Wirtgen have provided us with exceptional service and support.”

McLoughlin points out there has been and will continue to be numerous challenges on the State Route 60 rehabilitation project, from traffic control

CON C RETE CO NS TRU CT I O N / 2 0 1 9

to strict time management practices. “There are so many individuals that continue to do such a great job on this important project. I wish to thank them all, especially Ryan Vanderhook from RV Concrete out of Anaheim,” continues McLoughlin. “He has the enormous responsibility of providing us with around 3,200 yards of concrete for each weekend closure, and he is going a terrific job. J. McLoughlin Engineering is very proud to be associated with this inspiring project.” J. McLoughlin Engineering, Inc. is based out of Rancho Cucamonga.

GRANITEROCK OFFERS GREEN CONCRETE ALTERNATIVES AS DEMAND INCREASES FOR SUSTAINABLE CONSTRUCTION MATERIALS

By Brian Hoover, Editor

The sustainable recycled construction materials industry has grown in demand exponentially over the past several years with reports projecting it to be a $364 billion industry by 2022. Various green building material offerings like fiber cement siding, thermally modified wood, bamboo, hempcrete, flyash, ashcrete, and recycled plastic are growing in demand in the commercial/ residential building industry and civil general engineering infrastructure development business. The reasons for the demand and excitement include energy-efficiency, moisture-resistance, durability, reduced maintenance, emission reduction, and cost savings.

As the construction industry continues to focus on reducing energy consumption and CO2 emissions, the demand for recycled aggregates and green construction materials continues to rise.

A recent study reports that 2018 witnessed the sale of more than 3.7 million tons of recycled

12

construction aggregates in the United States. Part of this recycled aggregate supply went into the production of green concrete, which has been defined as concrete that utilizes waste material as at least one of its components. Other defining aspects include high performance and life cycle sustainable

CON C RETE CO NS TRU CT I O N / 2 0 1 9

products that do not contribute to environmental destruction.

Portland cement is one product supplemented with 25 to 100 percent fly ash. Portland cement is produced through the use of natural gas or coal, which uses significant amounts of energy to heat the materials used to manufacture Portland cement.

C A LCO N T R AC TO R .CO M

Above: Graniterock installing a green alternative mix design on the San Jose Airport $58 million Terminal Expansion Project.

Less Portland cement in concrete means lower energy utilization and lower CO2 emissions. Fly ash is a byproduct of other industrial manufacturing and can be reused in producing green concrete, which cuts the amount of Portland cement needed and results in lower CO2 emissions and drastic energy savings.

California developers, owners, and government officials are faced with growing environmental and economic mandates. Because of this, they are continually seeking innovative and efficient building solutions that will conserve energy, lower emissions, and save limited financial resources.

Green concrete is one solution currently used in California, and Graniterock is on the leading edge of its production and use in a long list of projects across the San Francisco Bay Area and

CALCON TRAC TOR .CO M

Central Coast. They recently completed several projects with green concrete, including work at the San Jose Airport expansion project, the San Francisco International Airport, and currently at the Avaya Stadium, home to the San Jose Earthquakes.

Zack Booth has been working for Graniterock since 2002 and currently serves as sales manager. Along with overseeing relations with contractors, he also manages volume and revenue for the company’s concrete plants in San Jose and Redwood City.

After graduating from UC Santa Cruz in 2002, Zack started in the company’s research laboratory, where he became an expert on the chemistry of concrete. He then moved on to work at Graniterock’s concrete and building materials branch in Santa Cruz before getting the call to take over as the

Bay Area concrete sales manager.

Zack has been instrumental in Graniterock picking up large pours in recent years for highrise apartment buildings, bridge decks, parking structures, and highways.

The concrete division has since grown to the point where Graniterock has expanded with improved and increased concrete plant capacity, and the addition of several new mixer trucks, and two additional sales team members.

“Our focus was to get new customers, so we started bidding on larger work that Graniterock hadn’t historically gone after.

We started putting our name out there and got a few jobs where the big contractors figured out we know what we are doing,” says Zack. “At the end of the day, it’s about keeping Graniterock people working. We know if we can

serve our customers better than anyone else, they’ll keep coming back, and Graniterock people will continue to have the opportunity to do good work and provide for their families.”

Going Green at the San Jose Airport Expansion Around a year ago, Graniterock was asked to produce and install a green alternate mix design for the $58 million terminal expansion project at the San Jose Airport. Graniterock’s contract included restructuring the southeast cargo ramps with more than 42,000 yards of concrete made with supplemental cementitious materials, slag and fly ash, resulting in remarkable CO2 savings, and reduced

14

cement use by more than 10,000 tons. They also utilized 50 percent less virgin aggregate in the production of the lean concrete base, with recycled aggregates, along with a 50 percent cement replacement.

Graniterock teamed up with Vanguard Construction to place the low slump concrete with a specialized concrete paving machine. The mix design called for replacing a portion of Portland cement with 15 percent fly ash, which was also used in the first phase of construction.

“We finished the final Terminal B Phase in April 2019, and we were originally tasked with producing a green mix design for a base course and for the taxiway itself,” says Zack. “Over the entirety of the project, Graniterock produced

CON C RETE CO NS TRU CT I O N / 2 0 1 9

and installed more than 50,000 yards of sustainable green concrete, made with industrial byproducts that significantly reduced the carbon impact and overall cost on this important project.”

San Francisco International Airport Parking Garage Built with Environmentally Friendly Concrete Providing travelers with more parking options is part of the ongoing strategic plan at San Francisco International Airport.

Graniterock has been doing their part to help meet that demand most recently by supplying around 40,000 yards of green concrete for a new parking garage next to the airport. The five-story parking

garage is a 1.2 million square feet structure with 3,600 spaces. The job began in August 2017 by the general contractor, Nibbi Brothers, and concrete contractor, Bomel Construction of Las Vegas.

Graniterock provided a concrete mix of 50 percent supplemental cementitious materials for the foundation and 30 percent in the garage decks. They also offered a green mix for the numerous square columns that included 10 percent of supplemental cementitious materials and a foundation with 45 percent recycled materials to meet the contractors green building requirements. The parking structure was completed in June 2018 after Graniterock was awarded the supply contract for the second portion of the job. “We went greener than the mandated 30 percent due to the

16

soil conditions,” says Zack. “Our crews and production personnel are the best in the business. Katha Redmon and Angie Solorio did an excellent job with creating and testing the mix designs, while Don Birt, Jennie Stewart, and Nick Martin made sure the numerous loads were all scheduled and delivered on time. Mike Baker and his operating team at the Redwood City plant went the extra mile to make it possible to batch the different green mixes.

Additionally, Nick Pereira worked closely with the mixer drivers so the pours that started at 4 a.m., all ran smoothly, and nothing was missed.”

Graniterock is a Californiabased construction materials and contracting company operated by the same family since 1900.

Their flagship quarry is located in Aromas, and Graniterock is

CON C RETE CO NS TRU CT I O N / 2 0 1 9

the Monterey and San Francisco Bay Area’s premier supplier of high-quality aggregate, sand, concrete, recycled aggregate, hot mix asphalt, and other building materials. Their construction division is a leader in heavy civil infrastructure projects, known for executing high-quality paving, excavating, grading, cold-inplace recycling, concrete finish work, and underground utility services. Graniterock’s research and technical services team has developed over 1,000 concrete mix designs to meet the most exacting specifications.

A & S Cement Contractor, Inc.

Proudly Serving the Concrete Construction Industry with Family Owned and Operated Pride Since 1976

By Brian Hoover

Albert Madrigal started doing small concrete site work jobs in the late 60s that consisted primarily of simple place and finish projects.

Then in 1976, Madrigal acquired his contractor’s license and started A & S Cement Contractor. His next step in the evolution came in 1984 when Madrigal incorporated and added a specialized truck and equipment to begin taking on curb and gutter projects. There were a glut of tilt-up construction jobs going on around this time and Albert would walk from one job to the next and ask if they would like a bid on concrete work. They grew one project at a time with slow and steady progress from that time forward. Albert struck up a conversation one day with an estimator friend who asked him if he 18

had ever considered getting into the tilt-up construction business. The man emphasized that he had some excellent carpenters who would gladly join him if he chose to give it a try. Albert jumped at the chance and stayed busy until around 1988 when the economy took a hit, and A & S began to struggle financially.

Albert decided to go back to what he knew best, and that was small site work and curb & gutter contracts. He maintained a small crew and was doing pretty well until 1993 when another economic downturn took him down to just five or six employees. Albert studied the situation and decided that he needed a talented estimator and eventually found one that he liked and trusted. His business began to grow again, as he took on

progressively larger jobs, and this is when his son, Sergio, joined the company fulltime. “I didn’t work for the compnay in high school or college, but my dad’s eyesight started fading, and I stepped in to help him out. The next thing I knew, I was jumping into the deep end feet first.” [ Continued on page 20] C A LCO N T R AC TO R .CO M

A & S Cement Contractor, Inc. was still doing sidewalk and small curb and gutter jobs around the time that Sergio joined the company full time in 1998. “We were lucky enough to get a big site work job with McCarthy, and another large project in Anaheim for Summit Builders when they came into town from Arizona.

From there we landed a couple of huge public works contracts with Tai Sei out of Hawaii and Japan,” says Sergio. “Both jobs were around $2 million each, one at Los Angeles Trade Technical 20

College, and the other for East LA College. Other great jobs at other community colleges followed, and we were on a roll.”

Albert Madrigal died in 2009, and the business moved solely into the hands of Sergio Madrigal.

Sergio says that his father, Albert, was his mentor and insists that he taught him everything that he knows about the concrete construction business. He adds that his father was not necessarily an easy man to get along with or please but was a hardworking man who had his son’s best interest at heart. “I remember my first job as a foreman for my

CON C RETE CO NS TRU CT I O N / 2 0 1 9

dad. It was for McCarthy over at the California Science Center in Los Angeles back in 2004. My father entrusted me with entirely overseeing this $1.5 million job, and I was scared out of my mind,” says Sergio. “When things slowed down, I started helping out in the estimating department, doing what I could to pick up as much work as possible for the company. I landed a good job at the Metrolink Station in Corona, and we made some good money on that project.” Sergio’s father taught him well, and it was now his time to make use of all those years of training and experience.

A & S Cement Contractor, Inc. has anywhere from 45 to 60 individuals working hard for them at any given time, depending on the workload. They are signatory to the Laborers, Cement Masons, and Carpenters union. “Site concrete and projects with small outbuildings is what we do best.

Around 95 percent of our work is on public works projects for schools or government jobs,” says Sergio. “We do a small amount of private work, but public works is our bread and butter.” One of A & S Cement Contractor’s most significant contracts was a $2.5 million job for the San Bernardino

Transit Center. A & S performed site and grading work that included a lot of flatwork, and construction of pedestrian walkways and building construction from block wall footings to structural concrete.

They also perform smaller, more unique, and intricate projects, like the work they did for Kemp Brothers at the Monsignor Oscar Romero Charter Middle School in Los Angeles. “We worked in extremely tight quarters, and our crews did an incredible job throughout the project, including some pretty amazing colored concrete sections,” says Sergio.

“Every day is a challenge, and

CALCON TRAC TOR .CO M

each job has its unique challenges, because you have to interpret the plans and what the owner or landscape architect wants. We need to see the job through their eyes and give them exactly what they are visualizing. That means asking questions and being aware of exactly what the client’s expectations are at the end of the job.”

A & S Cement Contractor, Inc. recently finished a project at Sherman Oaks Center for Enriched Studies in Reseda where they were contracted to remove and replace existing concrete slabs, seat benches, sidewalks, and add

ADA compliance sections. “This was our first job doing the demo, scarification, and recompaction soil work,” says Sergio. “We poured around 400 cubic yards of concrete on this job, and our guys did a great job of getting this education center ready for opening day. We are also just finishing up work for Dale Jr. High School in Anaheim and a job out at Willowbrook-Rosa Parks Station, as well as concrete site work at the Yorba Linda Library Community Center.”

A tremendous amount of physical human labor goes into every job that Sergio Madrigal and his crews take on each day, but much of the work requires the use of sound, reliable construction machinery. “We purchased a brand-new John Deere 332G skid steer loader from Coastline Equipment specifically for the project that we just completed in Reseda at the Sherman Oaks Center project,” says Sergio.

“Many of these school projects call for the excavation, grading, and compaction of new base material and our John Deere skid steers to the job effortlessly.” A & S Cement Contractor, Inc. owns and operates three John Deere skid steers, including the 320E, 326E, 22

and the new 332G. They also have a Hitachi 50U compact excavator that they use for excavating planter and seat bench walls and footings.

Additionally, they own a Volvo compact excavator and a 1999 New Holland skip loader. “For me, it comes down to customer service, and you are not going to find anyone better than JR Van Osten and Kenny Carpio who sold us our most recent skid steer loader,” says Sergio. “JR was relentless in a good way when he was going after our business. He just kept coming back with ideas and specific machines to look at and demo. He eventually called on me at the exact right time when I needed additional equipment, and we have gotten along famously ever since. Coastline takes care of our every heavy equipment need, and I would rather own than rent.

Working with Coastline Equipment has made that process a no brainer.”

Sergio Madrigal points out that maintaining a reputation for excellence and attention to detail only comes from the people that you have working for you on every job site large or small. “We have some great foremen and an awesome set of core operators

CON C RETE CO NS TRU CT I O N / 2 0 1 9

and laborers working here at A & S. It is about performing as a team because it is true that a team is only as strong as their weakest member,” says Sergio.

“My best friend is Michael Schunk, our preconstruction manager who heads up our estimating department, and our wonderful foreman, Jose Diaz, has been with me since I finished my first job on my own at the California Science Center back in 2004. His son, Fernando, serves as one of our superintendents who joined us in 2006. My sister, Marina Rodriguez, is our office manager, and we all work together as a family to keep every job measuring up to our client’s expectations. We plan on building on the momentum we have experienced over the past several years. That will mean looking for new talented individuals and advancing the best that we currently have to foremen and superintendents. I am excited about what the future has in store for us here at A & S, and I think that my dad would be very proud of our progress.” For more information on A & S Cement Contractor, Inc., please call (714) 220-2694.

A&P DEVELOPMENT AND CONSTRUCTION, INC. COMBINES TRADITIONAL VALUES AND TECHNOLOGY TO SOAR ABOVE EXPECTATIONS IN BOTH THE PRIVATE AND PUBLIC CONSTRUCTION SECTOR

By Brian Hoover

A&P Development and Construction, Inc. is a family-owned and operated company founded in 1989 by the father and son team of Armando and Peter Ocampo. As a full-service commercial/industrial general building contractor, A&P Development and Construction, Inc. has built upon its reputation for maintaining only the highest quality standards. As a general contractor with both an A and B license, A&P Development and Construction, Inc. self-performs many of the trades with their professional workforce. Ray Clantz is the company’s operations manager and oversees all of the office and field level procedures. Their major self-performed trades include 24

structural concrete, concrete, and civil demolition and earthwork, seismic upgrades, carpentry, as well as metal stud framing and drywall. “We perform both public works and private construction equally on general civil, structural and concrete flatwork projects throughout Southern California,” says Clantz. “Anything from the ground down, we will self-perform, as well as above ground structural concrete projects where we do all of the forming and pouring with our in-house crews. We subcontract out the mechanical, electrical, and plumbing duties to the industries top subcontractors.”

A&P Development and Construction, Inc. will take on

anything from an $8 million renovation project like the one they are on for Los Angeles Metropolitan Transit Authority (MTA), all the way to small ADA upgrade projects for private clients that are mandated to meet current compliance standards. A&P Development and Construction, Inc. recently started their work at the MTA Division 1 Renovation project where they are performing a full facility upgrade and stripping most everything from the roof down. They are also doing the excavation and installation of new upgraded underground utilities for the newly renovated structure.

The MTA job is a LEED recertification project that will replace much of the outdated C A LCO N T R AC TO R .CO M

technology with energy-efficient units, along with recycling demoed materials wherever possible. The project will be completed sometime in the first quarter of 2020 and will include new administration offices, new roofing, and new HVAC systems, among other things.

A&P Development and Construction, Inc. has a long list of other projects going on right now, including the construction of a parking structure in Palos Verdes, and the demolition of a two-story retail shopping strip mall and bank in Rolling Hills Estates. “We are demoing out the existing two-story retail center and putting in a new shoring system from the ground up. This job also includes sidewalk upgrades and the installation of new approaches, CALCON TRAC TOR .CO M

as well as concrete demolition, recycling of reusable materials, site clearing and the addition of a new parking structure. One of the most interesting and complicated parts of the job would be the storm water retention and percolating system we are installing that includes four 20,000 gallon tanks excavated and placed under the new parking structure,” says Clantz. “This system is required to capture runoff from the structure to keep toxic chemicals, oils, and other pollutants from entering the storm drain. These tanks collect the runoff and percolate and filter the water.

When the tanks are full, they pump the water into four large concrete planters that we are constructing that are designed to keep the water on-site. Any overflow will

then be pumped out into the storm drain system.” Clantz explains that they are constructing the concrete planters using a stepdown construction method where the first planter is around 20’ x 6’ and 8 feet deep with 10” thick walls, and then steps down to the other basins to eventually land in a larger 40’ x 20’ planter box.

Another exciting project that A&P Development and Construction, Inc. is currently on is being constructed for an Air Force base in Southern California.

“We are removing an existing 50,000 square foot concrete courtyard area that will be replaced with a new paver system. We will be pouring a ribbon of concrete around the perimeter as well as a square

section on the inside of the new courtyard area,” says Clantz. “We started the project a few months ago and will be finished within the next few weeks.” Additionally, A&P Development and Construction, Inc. is performing another project for a new plaza in El Segundo.

“The owners of this particular project have specified the use of a top cast finished concrete surface, along with specialized architectural concrete benches. Special requests like this keep our job interesting, and our craftsmen are the best in the business.”

The type of work that A&P Development and Construction, Inc. does each day requires the use of robust, reliable equipment, and Ray Clantz only owns one particular brand. “We go with Caterpillar equipment, and Quinn Company Cat is the dealer we have trusted for many years,” says Clantz. “I have learned from owning past businesses that it always pays off to do business with companies that have a proven track record and a long history of quality and excellence. Cat is one of those companies and our representative, Derek Miller, has 26

done a great job of looking after our every need.” Clantz also points to the fact that his equipment is utilized in some pretty harsh environments, and he goes with Cat because it is proven dependable and backed by research and development that goes back nearly 100 years. “We use our three Cat skid steer loaders in one capacity or another on most all of our job sites because they are our most maneuverable machines and are capable of handling a multitude of tasks. We use them to break up existing concrete, to excavate, grade, and load or unload trucks,” continues Clantz. “We currently own three Cat skid steer loaders (Cat 236D, 246D & 262D), one medium (Cat 315F) and one compact sized Cat excavator (Cat 305.5E2), a Cat compaction roller (Cat CB24B) and an older Cat 420E backhoe. We have owned our Cat backhoe since 2006, but the other Cat machines have been purchased within the past three years, and operating newer, low hour Cat machines is how we want to keep things around here.

We recently purchased a couple

CON C RETE CO NS TRU CT I O N / 2 0 1 9

of Cat skid steers with 800 lb. hammers and I admit that I was a bit skeptical about the potential performance of the smaller hammers. I am happy to say that both the skid steers and hammers have exceeded my expectations.

We will be adding a few more Cat machines soon.”

Clantz says that his company has been experiencing impressive growth over the past three years, most notably in the last 18 months. “The future looks positive and bright as long as we continue to set realistic goals and not get ahead of ourselves. Our infrastructure system in Southern California is aging, and our state is currently involved in a catch-up cycle right now. There will need to be a tremendous amount of new infrastructure to support this modern technology, and we want to be a part of that development while maintaining our plan for controlled and sustainable growth.”

California Building and Sitework Business

Above and Left: Overall structural layout and closeup of concrete pour in Anaheim for the Theodore Roosevelt Elementary School.

Hamel Contracting, Inc. was founded by Grant Hamel in 2008 to build and provide industrywide, project-specific solutions for both the public and private sector. With more than three decades of hands-on experience, Mr. Hamel has made it his purpose to help streamline the extremely complex general construction business for his company.

From general contracting to pre-construction, design and construction management,

28

Hamel Contracting, Inc. has done it all including work for schools, hotels, manufacturing, warehouse, distribution, civic and themed parks, office complexes and more. To date, the company has managed more than $450 million in high-quality construction projects.

Hamel Concrete, Inc. (Hamel Concrete) is a division of Hamel Contracting, Inc. and was established in 2016.

Jeff Hale is the operations manager for Hamel Concrete,

CON C RETE CO NS TRU CT I O N / 2 0 1 9

and he joined Grant Hamel in starting the division after owning his own structural concrete business for 18 years. The company is currently on an exciting job for Theodore Roosevelt Elementary School in Anaheim that began in April 2019 and is scheduled for completion in September 2020. “We are performing all of the structural concrete, waterproofing and concrete reinforcing, as well as the site architectural concrete

and integration of concrete pavers within some of the site work,” says Hale. “Once the general contractor has erected all of the buildings, we will be doing the remaining site concrete work like sidewalks and curb and gutter.”

Hamel Contracting, Inc. has the specialties/ miscellaneous package on the Theodore Roosevelt Elementary job, and according to Hale, the two companies often work together with separate contracts on the same project. Hamel Concrete’s contract is just over $5 million for this particular project, and it is not your everyday concrete flatwork project. “The sheer volume

CALCON TRAC TOR .CO M

and size of the footings and deep excavations on this job have made it unique and a bit of a challenge. There is also the challenge of the steel bolt templates and coming up with a method where we can support them while we place rebar around and on top and then finally pour the concrete over the forms,” says Hale.

“The job is unique if only by the grand size of certain portions of the project. Some of the footings are up to 4-feet thick, 13 feet wide and over 70 feet long, and around 230 yards of concrete is required to fill just one of them.”

Hale also points out that out of the 7,000 total yards of concrete expected to be used on the Theodore

Roosevelt Elementary project, 3,000 yards will go into the building foundations alone. “These are twostory classrooms being constructed, and that is one of the reasons why the foundations are so large,” says Hale. “I have been doing this work for 34 years, and these are probably the largest foundations we have ever poured right here at this elementary school.

“Additionally, we will be pouring on the second story, and there will be quite a bit of concrete placed on the roof level as well.”

Hamel Concrete is self-performing the concrete work on the Theodore Roosevelt Elementary project, and they have

subcontracted the reinforcing work to Upland Contracting.

“We have these unusually large structural steel bolt tablets that we are having to set and pour concrete around, with some weighing up to 2,600 pounds each,” Hale says that some of these bolt tablets are 5 feet long, 5 feet tall and around 2 feet wide, and the entire project calls for the use of nearly 100 steel bolt templates. “This is a unique and challenging project, and I want to thank and recognize all of our crew members and foremen, Trevor Hoffer and Dominic Garcia,” says Hale. Hamel Concrete is on numerous other school projects, including one just around the corner from the Rooselvelt Project. “We are currently on the Sunkist Elementary School project with general contractor Pinner Construction. It is less than

30

2 miles from the Roosevelt Project and is another goodsized project with around 4,000 yards of concrete expected to be placed,” says Hale.

Hamel Concrete is always looking into equipment and technology that will give them an edge in the competitive concrete construction industry. “We recently started using Giatec Bluerock 2 sensors on slab pours that are designed to monitor the relative humidity and temperature of the concrete wirelessly. The results can be downloaded using a mobile app or downloading to a tablet or smartphone,” continues Hale. “Concrete is a sort of living animal, and we use this new technology to monitor slab curl and vapor emissions from coming through the slab. By the time the floor coving guy comes

CON C RETE CO NS TRU CT I O N / 2 0 1 9

on-site, he is checking for relative humidity as well, and we can compare our data for optimum consistency and results.”

It looks like the next three to five years will remain busy for Hamel Concrete in the public works arena.

“The only way we can grow from this point forward is to find good foremen and superintendents that can run the work up to our stringent standards,” says Hale. “You can’t be driven by revenue alone. You must have the right people on these projects, or you are going to lose money. If we can pick up exceptional talent in the future, then we will continue to grow.”
