CIVIL ENGINEERING
SMG provides a wide variety of civil engineering designs for our clients. These designs are tailored to the unique nature of our projects. Some of these designs have included; innovative soil retention structures, shallow and deep foundations, dock facilities, grading plans, storm and process water management plans, industrial recycled water systems, and concrete flatwork. In addition, SMG has provided heavy civil contractors with design in conjunction with our other fields of expertise.
Gear Locker BuildingVancouver, WASMG designed a new 25,000 square foot facility for the Port of Vancouver to be used as a storage and maintenance shop for a Port tenant. It was critical to balance the needs of the Port, the needs of the future tenant, and plan for additional operations and projects around the immediate site. Time was a major constraint for this project and SMG was able to meet the stringent time requirements to provide design, permitting, and construction documents.
Scope of work included stormwater design, site utility design, structural design of foundations and mezzanine, construction cost estimating, full technical specifications, coordination of electrical and plumbing designs, permit acquisition (land use, civil, and building), and on-site engineering observation during construction. |
Irving Elevator Slope Stability Retaining WallPortland, Oregon
SMG designed this 600-foot-long riverfront wall to stabilize the soil under the grain elevator. The slope had failed and was sliding towards the river, taking the structures along with it. SMG designed the retaining wall in two primary sections; one was driven 30-inch-wide flange soldier piles with steel plate lagging; the other was auger cast concrete soldier piles, 4-foot diameter, 7-foot on-center. Both walls have pre-stressed strand tie-backs into the stable layer. These walls had to be placed through fill that contained rubble and other debris, making both driving and drilling of the piles very difficult. Other project restraints were a very narrow site with poor access, the need to continue facility operations, and the existing damage to the structures due to the slope failure. SMG provided civil and structural design, obtained the permits (including Corps of Engineers and greenway permits), and coordinated the contractor and geotechnical engineer.

Stockpile Dust Suppression System and Recycled Water System
Chicago, Illinois
SMG designed a dust suppression system for an open stockpile of bulk storage. The system consisted of approximately 45 water cannons mounted on 60’ high masts to distribute water over the 60 acre site. The system is separated into zones and controlled by a Programmable Logic Controller (PLC) to control the duration and active zones. This system is capable of remote manual operation, automatic menu operation, and is connected to weather monitoring equipment to adjust the operation by wind direction, rainfall, temperature, and storm activity. In addition, the design of this system included collection of all of the dust suppression water and rain water for storage and reuse through a recycled water system. The recycled system included a multiple pump system in response to the required pressure in the system. This resulted in a zero discharge site.

Recycled Water System
Pittsburg, California
SMG designed a water collection and recycle system for this truck to ship terminal. The system includes collection of process water from dust suppression, free water draining from the product, and wash down water. This water pretreated through a concrete settling and skimming pond system and a system to further treat the water, if necessary. This water is fed via a multiple pump system back into the system for reuse for dust suppression and wash down water. This system also included a separated storm water collection system which allowed the use of rainwater to be used as make-up water for the recycled system when necessary. This system significantly reduced the need to purchase and discharge water, resulting in both ecological and economic advantages.

Concrete Truck Wash and Settling PondSherwood, OregonSMG designed a three-bay truck wash station and settling pond. The plant's goal was to capture and recycle wash water and rainwater to reduce fresh water consumption. Twenty-five to fifty trucks per day use the truck wash area. Water from the final settling pond is recycled to outgoing trucks the following day.
