INDUSTRIAL PROJECTS

Nestles Waters North America (Dallas TX) – In conjunction with documents prepared and provided by SMRT, Price Structural Engineers, Inc. (PSE) performed the necessary stamped structural design for a series of renovations at the Nestles plant. Tasks included the design of a 33’ long cast-in-place underground storage tank covered by a structural slab rated for a 250 psf floor live load. Other requirements included the foundation design for two 55’ high x 11’ diameter silos (130 tons each) supported by deep reinforced concrete piers and a shared reinforced concrete cap. Interior requirements included the design of roof bar joist reinforcement to support suspended conveyors along with the structural design of several reinforced mat slabs on soils with low bearing capacity. Due to the complexity and layout of the large processing equipment column forces, the mat slabs were designed using “Ram Concept,” a well-established structural computer program which analyzes the mat slab using finite elements (for multiple load combinations) and then specifies the size and locations of the required reinforcement.

Portsmouth Naval Shipyard (Kittery, ME) – PSE was the structural engineer of record for the design of  two 20’ high x 33’ wide structural steel classified structures adjacent to the wharf at the naval shipyard. Requirements included overseeing the acquisition of field measurements identifying existing materials and developing a cost-effective design that interfaced the shipyards proposed concepts with actual field conditions. Once approved by the general contractor and the shipyard, PSE performed the structural analysis and design of the structure including the design of the connections. Field observations were made by PSE during construction to review the structural assembly work by the contractors.

Rumford Dam: Temporary Supports for Repair Barges (Rumford, ME) – PSE was retained by H.E. Callahan contractors to perform the structural design services needed during the wall restoration renovations at Rumford Hydro. Specifically, PSE was responsible for the connection design of cables to the dam wall so that floating barges supporting equipment, assorted materials and manpower could be held securely in place in the presence of the moving water during the wall restoration. Tasks included reviewing the barges, the barge connection points, and calculations identifying water flow drag forces, including angled prying forces, for the varying water level heights that could occur during the restoration process.

Carbon Fiber Waffle Slab Reinforcement, EMMC (Bangor, ME) – PSE was retained by Eastern Maine Medical Center to identify the structural effects caused by renovation loads being proposed for the existing 2nd floor waffle slab at the Grant building. The renovations included extensive modifications to the kitchen area along withTAVR operating equipment suspended below the floor. The structural analysis was based on architectural and equipment shop drawings, field measurements, and the original structural drawings for the building. The preliminary analysis confirmed that the floor would need to be reinforced. Due to the limited clear height below the waffle slab and the presence of extensive ceiling piping, the use of structural steel beams below the slab was not possible. Further analysis by PSE showed that carbon fiber reinforcement, along with structural steel at selected areas, was capable of supporting the anticipated loads. In order to use carbon fiber, however, ACI requires minimum capacities in the unreinforced slab so steps to reduce the renovation loads, including changing to lighter floor tile, were introduced to satisfy the ACI requirements. PSE used a combination of Staad-Pro finite elements design and hand calculations to identify areas needing reinforcement. Both shear and flexural reinforcement were required. Sika carbon-fiber products with corresponding resins were used and the installation of these materials was performed by trained workmen. 

Buxton Public Works Garage (Buxton, ME) – David Price was the structural engineer of record for the 9,600-square-foot public works garage containing 10 vehicle bays, an office area, overhead bridge crane, mezzanine jib crane, and mezzanine storage. Tasks included the structural design of masonry shearwalls and a high load garage floor slab at truck storage areas.

Western Avenue Fire Station (South Portland, ME) – David Price was the structural engineer of record for the steel framed two–story fire station with masonry shearwalls. The facility contains a fully equipped dormitory along with a hose tower and emergency equipment bays.  Special structural design was provided for the concrete slab to support the 80,000 pound vehicles while still providing in-floor heating. A basement was designed with an extensive drainage system to accommodate the seasonally high water table. 

Fort Buchanan Building 2 Maintenance Facility (Puerto Rico) – Working with engineers at SMRT during 2012, David Price performed the structural design for the new 270’ long steel framed maintenance building. Tasks included the design of a steel bracing system capable of resisting 145 mile per hour hurricane forces and corresponding wind uplift. The bracing was also designed to resist the substantial seismic loads that occur in the Caribbean caused by the precast exterior cladding and interior masonry block walls.

Wells Public Works Garage (Wells, ME) – David Price was the structural engineer of record for the public works garage containing 10 vehicle bays, an office area and mezzanine storage. Tasks included the structural design of masonry shearwalls and a high load garage floor slab at truck storage areas.

Brunswick Fire Station (Brunswick, ME) – David Price was the structural engineer of record for the 14,000 square foot fire station at Cooks corner in Brunswick. The facility has accommodations for eight firefighters, four drive-through bays, a hose tower with drying capabilities and serves as a back-up emergency control center for the town.  The apparatus garage bay is constructed of reinforced concrete block with a steel roof system. The dormitory is  constructed with a wood truss roof system creating a contemporary exterior appearance while effectively controlling construction costs.

Pedestrian Truss Bridge and Wharf Waterfront (New Orleans, LA) – Price Structural Engineers performed the structural design of the 114-foot steel truss bridge spans over an existing river in New Orleans.  Our firm’s challenges included designing for lateral hurricane forces from 140 mile-per-hour wind, slide bearing for expansion/contraction, bolted field splice connections, and resistance to corrosion. Restoration of the existing wharf included redesign of the existing platform for the automated gangway system and loading crane.

Anheuser-Busch Beta Tank Replacement (Merrimack, NH) – David Price was structural engineer for the renovation involving the design of structural steel frames supporting new 200 ton elevated tanks.  Other requirements included evaluation of floor live load requirements and temporary removal of both structural masonry and steel components to obtain access to the second floor of the existing building.

Manchaug Dam Steel Gate Repair (Sutton, Massachussetts) – Based on design parameters and recommendations provided by Devine, Tarbell & Associates, David Price performed the structural design and detailing for the replacement of the existing operable gate. Tasks included developing the installation sequence to minimize risks for underwater divers while still meeting the client’s aggressive construction schedule.

Rathdrum Power Plant (Rathdrum, Idaho) - Working with engineers at IEA Associates, both David and Teresa Price provided the structural design for multiple components within the new power plant. Their tasks included designing the four-story structural steel frame for the zero waste system, the foundation design for the cooling tower, the boiler feed pump monorail framing, the bracing design for the primary operating floor and numerous underground concrete tanks. Both firms used identical structural computer software (STAAD-Pro) to facilitate electronic transfer of structural files.
