Blackstone River Viaduct Bridge Contractor Support Services LINCOLN / CUMBERLAND, RHODE ISLAND
The Blackstone River Viaduct Bridge No. 750 was built in 1963 and carries Interstate 295 northbound and southbound over the Blackstone River and the Blackstone River Bikeway. The 688-foot bridge includes four continuous spans with haunched steel plate girders. Rehabilitation is expected to be completed by 2013. Northbound/southbound traffic is carried by separate bridges, both of which are being rehabilitated. For most of the construction, at least one direction of the interstate will have a traffic split. Steere Engineering prepared several shop drawing submittals for both Cardi Corporation and J.R. Vinagro Corporation. Steere prepared deck demolition and deck placement analyses using finite element models of the multi-span bridge to quantify concrete deck and steel girder stresses from the demolition and pouring sequences and equipment to avoid overstressing the girders or cracking of the deck. Steere was also responsible for the overhang bracket and temporary shielding design as well as the formwork design. Steere collaboratively worked with Cardi Corporation to develop a design for the shielding and formwork that was both constructible and cost-effective to the contractor and owner.

Branch Avenue Bridge Contractor Support Services PROVIDENCE, RHODE ISLAND
The Branch Avenue Bridge carries two-way traffic over the West River in Providence, Rhode Island. The bridge is located in a tightly confined urban setting, with two lanes of traffic in each direction and low-lying power lines directly above the north side of the bridge. Steere Engineering was tasked with the design of the pile-supported temporary bridge abuments and development of erection procedures for both the temporary bridge and permanent bridge. The permanent bridge structure consists of 11 precast concrete girders spanning approximately 48 feet over a single span. The bridge carries pedestrian traffic on both sides and supports utilities under the deck. The permanent erection sequence was complicated by the powerlines located directly above the north side of the bridge. OSHA requirements for construction near powerlines were held by using a tandem pick for the affected beams. The construction site was very tight and phased construction was required, making use of the prefabricated temporary bridge to keep at least one traffic lane open at all times during construction for this heavily traveled, urban roadway.

I-195 Ramp Bridges PROVIDENCE, RI
The I-195 Relocation Project in the city of Providence, RI relocated the junction of two major interstate highways, I-95 and I-195. The original intersection, built at the inception of the interstate in the late 1950s, had many substandard highway alignment features including left-hand exits as well as deteriorating bridges. As part of the project to correct and bring the highways up to modern standards, a series of seven ramp bridges were built.
The seven ramp bridges are multi-span steel, trapezoidal box girder bridges with the longest ramps over 1,500 feet in total length. Spans are up to 250 feet long. The bridges feature three integral pier caps and uneven span lengths due to the congested urban site where they were built. High performance steel was used for the fracture critical integral pier caps, as well as the two-girder bridges. The bridges were modeled in three dimensions using a combination of SAP2000 and Descus. They were designed in accordance with AASHTO Standard Specifications for Highway Bridges, 17th Edition for an HS-25 loading and seismic loads.

Whigville Dam & Spillway Improvements New Britain Water Department NEW BRITAIN, CT
The exposed face of the Whigville Dam’s 350-foot-long retaining wall had deteriorated, particularly below the high water level. Earlier proposed repairs exceeded New Britain’s budget. We developed a program of high-quality, prioritized repairs that would extend the life of the dam and make best use of the City’s available funds. Most damage to the wall face involved cracking and delamination of an earlier surface facing from the original concrete, in generally good condition. Field evaluation of concrete removal techniques assured careful removal of the deteriorated concrete without damage to the sound concrete substrate. Local repair of deep spalls and injection of cracks was done as needed. Attention to the details of dowelling between new and existing concrete layers, concrete design mix, additives, bonding agents and repair materials assured compatibility and maximum durability. Repairs also included repointing of the stone face of the spillway interior, repair of the spillway bottom and resurfacing of the concrete spillway cap, requiring precision to match existing profile and elevations for compatibility with the Water Department’s measurement procedures. Involvement in the construction process helped assure quality repairs and enable quick and effective response to field conditions as they were uncovered.

The design of the wall elements included no structural reinforcing steel, which should greatly prolong the life of the concrete in the corrosive ocean environment.
This project was advertised as an emergency repair by the City of Newport. The designbuild team, consisting of Contech Construction Products, Gary K. Munkelt & Associates, and Mello Construction Co., was coordinated and led by William G. Young. Together the team developed a completely new, custom/hybrid Re-Con®/Tensar® Geogrid and Armorflex® complete replacement solution for a failing section of seawall, circa 1930s. Of the nearly twenty teams who submitted proposals, the team led by Mr. Young was the only one to propose a complete replacement of the failing wall. The proposed solution was still well within the total project budget and competitive with other teams who were only proposing a “cap and repair” solution. The project was federally funded with RIDOT acting as the liaison. Therefore, all materials used on the project as well as the design were submitted and concurred with by RIDOT acting on behalf of the Federal Highway Administration (FHWA). It should be noted that this first-of-its-kind wall performed as intended during Hurricane Sandy in late October 2012.

Design and Construction Support Providence River Bridge PROVIDENCE, RHODE ISLAND Photo Credit: Steven Wilkinson
The Providence River Bridge, also known as the IWAY Bridge, is a seven-span, 1,250-foot-long bridge carrying Interstate I95 over the Providence River. The main span is a 400-ft-long network arch bridge. Based on research into network arch bridges it was decided to use the network arch cable arrangement to reduce the moments in the arch and tie cross sections and obtain a light weight and structurally efficient design. Network arches had been used in Europe and Japan, but the Providence River Bridge is the first such bridge in the United States. The Providence River Bridge carries the heavily travelled Interstate 195 in downtown Providence. The bridge is designed to carry five lanes of traffic in each direction resulting in a 165-ft-wide structure. Due to its large width, it uses three arches rather than two. Three arches were used instead of four due to the site-specific space constraints caused by the Fox Point Hurricane barrier to the north and a 110-year-old brick sewer siphon running to the south.
Network arch bridges save considerable amounts of steel because they behave like trusses as long as the cables do not relax under loading. This reduces the bending moments caused by uneven live loading and enables the arch and tie cross sections to be reduced. The bridge was built offsite and floated into place. This type of construction was made feasible by the lightness of the bridge. Self-propelled modular transporters (SPMTs) were used for the first time in Rhode Island to transport the bridge from the pier at Quonset Point to barges and floated to Providence. The move was featured on the History Channel’s Mega Movers program on “Really Big Bridges” in 2007.
Patricia Steere, while with a Northeast engineering firm, was the Lead Design Engineer from preliminary through final design, and Engineer-of-Record for this bridge. Design was completed in 2003, and the bridge opened to traffic in 2007. OWNER: Rhode Island Department of Transportation Two Capitol Hill, Providence, RI 02903 T: 401.222.2450 | E: email@example.com

Rhode Island Truss Ratings VARIOUS LOCATIONS IN RI
As Part of a continuous effort to inspect and assess the State’s bridges, Steere Engineering is performing bridge ratings for the Rhode Island Department of Transporation.
The inspections and inspection reports were completed as a separate contract by others. Steere used the inspection reports to assess the condition of the truss members and gusset plates. The trusses and gusset plates were rated in accordance with the latest AASHTO Manual for Bridge Evaluation, RIDOT Guidelines for Load and Resistance Factor Rating (LRFR) of Highway Bridges, and latest edition of AASHTO LRFD. SAP 2000 was used to conduct the moving live load analysis on the trusses. Forces from SAP were then exported to Excel for rating purposes.
The first round of bridges completed by Steere Engineering, as a sub-consultant to WSP Sells, was a group of five truss bridges. The bridges, located in Woonsocket and Coventry, are steel trusses dating from the 1950’s with the exception of one wrought iron truss built in the 1890’s and made famous by the Phoenix Bridge Company. The Phoenix Bridge Company patented the Phoenix column, an innovation of the time, which used wrought iron segments rivited together into a single column. This allowed for a significant weight reduction over soild wrought iron columns, allowing for much longer spans.

Structural Analysis & Anchorage of Water Treatment Equipment SIEMENS INDUSTRY, WATER TECHNOLOGIES KEMPER COUNTY IGCC, MS Steere was engaged to provide structural engineering services to Siemens Water Technologies Unit for its submerged microfiltration membrane water treatment systems. The Siemens installation for Kemper County, Mississippi, required structural engineering expertise to analyze the equipment, support framing and anchorage to assure its compliance with local building codes as well as operational functionality.
The Kemper County installation includes steel framing that supports its â€œMemsapâ€? (membrane service access platform), a motorized platform that travels over tanks containing the membrane filters and contains hoists for removal of filters for maintenance. At this installation, the Memsap travels on rails across concrete tanks and steel moment-connected support frames at each end of the tanks. Steere Engineering analyzed the steel moment frames, using SAP 3-dimensional analysis software, for the loads imposed by the moving Memsap, the lifted filters and associated equipment, including motion-induced impact forces and seismic forces. Frame member capacities, frame connections and operational deflections were checked for compliance with IBC and AISC code criteria and with serviceability needs. Steere also designed anchorage for the bases of the frame columns, for process air and filtrate headers and other equipment that Siemens is supplying, based on operational and seismic demands in compliance with ACI 318, Appendix D anchor design requirements.

Stillwater Viaduct Bridge Rehabilitation SMITHFIELD, RHODE ISLAND
“We are definitely pleased with the results …it was gratifying to put the bridge back into service five weeks early…. “We are fortunate to have had such an accomplished team… Accelerated bridge techniques are relatively new to RIDOT, but… we plan to use similar techniques on future projects.” Heidi Gundmunson RIDOT Spokesperson
The Stillwater Viaduct is 898-foot multi-span structure consisting of two approach spans and a main span arch over the Woonasquatucket River. The original Stillwater Viaduct was constructed in 1927. Steere Engineering, as the consultant for contractor, Northern Construction Service LLC, was responsible for preparing the demolition and shielding procedures in addition to the procedures for erection, temporary jacking and shoring, deck pouring, and formwork design. The demolition and erection procedures included the use of 275-ton hydraulic cranes on the bridge. The existing structure was analyzed for crane loadings during both travel and picking operations. Prefabricated 200-kips shoring towers were used to support the structure beneath the crane outriggers during picking operations. To accelerate the superstructure demolition, full span sections of double cast-in place beams, deck and diaphragms were picked and lowered to grade to be hauled off-site for complete demolition. In addition, Steere Engineering was responsible for the design of the shielding support anchorages fastened to the existing arches and columns as well as the cantilever support framing for the debris nets above the river. The erection procedure consisted of a multitude of precast components to be erected and checked for stability including: approach span beams, bent caps, transverse floor beams, deck panels, and parapet railing. Lastly, to support the contractor’s accelerated construction schedule, a jacking procedure was developed to allow for the erection of the precast transverse floor beams prior to the installation of the isolation bearings at the precast bent caps. Originally RIDOT considered phased construction that would have kept the bridge partially open to traffic but would have taken years to complete. RIDOT closed the bridge in March 2012 to allow crews to work more quickly; with accelerated construction techniques, the historic bridge opened five weeks ahead of schedule in October 2012.

Veterans for Tomorrow HISTORIC MILL BUILDING RESTORATION PROVIDENCE, RI
The three-story Cowing & Heaton Mill is a timber-framed, historic mill building being converted from its original use to residences for veterans, incorporating apartments and public spaces. The building was originally constructed in the 1840s with subsequent additions and modifications including a fire early in its life. Abandoned for a period of time, the building showed significant water damage to areas of the structural flooring and timber girders. Steere also found decay at the bases of columns that had been encased in concrete during one of the building’s renovations. Steere’s work included evaluating the structure’s capacity to support loads for the building’s new use, repairs of deteriorated and damaged elements, and structural modifications for new features. Repairs included reinforcing damaged beams, replacing badly decayed timber framing and modifying column bases to replace areas of decay and to raise them out of the concrete floor where they were exposed to moisture. A three-story elevator shaft was fit into the building footprint with foundations, including new footings under existing columns that would be undermined by the new elevator foundations.

Contractor Support Services Washington Pedestrian Bridge PROVIDENCE / EAST PROVIDENCE, RHODE ISLAND
This project involves rehabilitating the 1,660 foot historic concrete arch viaduct and converting the former vehicular bridge into a plaza style multi-use recreation path linking the East Bay/West Bay. Steere Engineering, as consultant for Cardi Corporation, provided the designs behind the contractorâ€™s means & methods. This project includes the design of multiple spans of temporary access bridges, associated erection procedures, and temporary abutments providing the contractor much simpler access, as opposed to barge-only access assumed as part of the design contract. Cardi sought to utilize self-owned steel plate girders to construct the temporary access bridges. Steere analyzed these girders, designed multiple field splices, and prepared drawings and supporting calculations per current AASHTO codes, which allowed their use. The bridges were designed to accommodate heavy construction equipment as well as crane travel used to supply materials to the bridge deck above. In addition, Steere analyzed the existing +75-year-old viaduct to accommodate both track and axle load crane travel, using finite element analysis to aid in the erection of these temporary bridges. The erection of these bridges was conducted using a phased procedure. Span 1 was erected with a crane located on top of the existing bridge in tandem with a secondary crane below at the approach. Span 2 was then erected with a crane on top and a secondary crane down below placed on the Span 1 access bridge. Steere also provided structural engineering services for demolition/shielding procedures, jacking and shoring procedures for bearing replacements, deck pouring procedures, and formwork design.

Road /RRX Reconstruction WESTERN AVENUE | STATEN ISLAND, NY
The Western Avenue project in Staten Island required complete reconstruction of roadways, railroad crossings, sidewalks, drainage and a water main. Multi-agency involvement included PANYNJ, NYCDOT and NYCDEP. The design complexity is evident in the project profile (above). â€˜
This 2,700-ft urban roadway / utility reconstruction project was triggered by the PANYNJâ€™s (Port Authority of New York/New Jersey) desire to install three, new, at-grade railroad crossings across right-of-way owned by the City of New York. To adequately protect the crossings from tidal impacts, the city street had to be re-profiled, and the hydraulics changed significantly. The project involved complete reconstruction of the roadway, sidewalks, drainage, and a 12-inch domestic water main along its length. The project was designed in accordance with NYCDOT and NYCDEP standards, but was advertised using PANYNJ standards.
There were numerous utility conflicts within the project limits; perhaps the most notable are privately owned twin 14-inch petroleum pipelines that run from New York Harbor to the Gulf of Mexico. This road and utilities reconstruction project was
conducted in connection with the proposed New York Container Terminal expansion at Howland Hook.
William G. Young, while at a different firm, was Senior Engineer for this work on behalf of the Port Authority.
