STRUCTURES

Design specialists bring a broad range of expertise in seismic retrofit, building design, bridges, transportation structures, pump stations, water treatment plants, culverts, channels, bulkhead walls, and infrastructure projects including the full range of retaining wall systems. The goal, as always is to create innovative designs to meet client objectives with economical results.

BUILDING STRUCTURES

Provide complete structural design and construction support services for public and private clients. Project types include multi-story commercial buildings, school and church buildings, industrial facilities and retrofit of structural systems.

HYDRAULIC STRUCTURES

Provide complete structural design services and construction coordination through project completion for public and private clients. Project types include utility buildings, pump stations, water treatment plants, culverts and headwalls, channels, bulkhead walls, and special foundation systems.

BRIDGES

Services include rehabilitation of aging infrastructure, seismic retrofitting of deficient structures, widenings for increased capacity, staged removal and construction, constrained right-of-way or access, and new or replacement structures.

Analysis and design, development of contract documents (plans, specifications/special provisions, and estimates), and construction engineering support for the full spectrum of structure types, including prefabricated, cast-in-place, and precast bridging structures utilizing conventional reinforced concrete, precast/prestressed/post-tensioned concrete, and structural steel members. Substructure and foundation designs include single piers and multi-column bents, Type I and II pile extensions, standard spread footings, small and large diameter cast-in-drilled hole piles, driven precast concrete piles, driven HP-shape and pipe piles, and large diameter cast-in-steel-shell piles.

TRANSPORTATION STRUCTURES

Develop and design buried steel and concrete closed-cell culverts and cast-in-place and prefabricated three-sided or bottomless arch culverts. Vast experience with a wide range of earth retaining structures, covering standard cast-in-place reinforced concrete cantilever walls, sheet pile and soldier pile walls with or without tiebacks, walers, soil nail and tieback wall systems with architectural facing, mechanically stabilized earth systems, rigid and flexible gravity walls with or without an integral soil reinforcement matrix, secant pile and tangent pile walls, and cement-soil mix walls. Design and integration of appurtenant connection facilities such as aerial ramps, buried tunnels, and guideways and stairways.

Project Case Study

ELVERTA ROAD/ SR99 INTERCHANGE PROJECT

COUNTY OF SACRAMENTO, CALIFORNIA

Wood Rodgers led a multi-disciplinary project team to complete management, planning, programming and funding authorization, environmental clearance, preliminary engineering and approvals, final design, right-of-way permits and acquisitions, and construction engineering support for a new local agency partial cloverleaf intersection with overcrossing structure to remove one of the last unsignalized intersections on SR99 in Sacramento County.
Key elements included:
o Integration of direct stakeholder interests, including Sacramento County, Caltrans, RD1000, utility owners, and regional interests for future expanded capacity along the SR99 corridor
o Development and delivery of planning documents (interchange GADs and Project Report)
o Assistance with environmental clearance and permitting, final Contract Documents (Plans, Specifications, and Engineer’s Estimate) for comprehensive transportation and structure improvements, canal realignment, utility coordination and relocations, Caltrans permitting and approvals, pedestrian and bicycle access, temporary and permanent traffic controls with intersection signalization, and street lighting
