SMG is experienced in a variety of water-front design services such as docks wharves, cofferdams, trestles, dolphins, and pile templates. SMG has also designed water-related equipment and structures such as barge hoppers and associated equipment, barge super-structures, bubble curtains, and underwater equipment. Many of SMG's employees are in possession of TWIC cards.
New Dock and Processing Facility
This new waterfront fish process facility that SMG designed includes a new 12,000 square foot concrete dock and a 75,000 square foot facility. The dock was designed for unloading of fishing vessels with unloading cranes connected to the dock. The dock was also designed to support a section of the new two story fish processing facility which included heavy equipment loading. SMG met unique design requests including crack-less concrete slabs to deal with stringent food industry requirements.
SMG completed the structural design of the dock, the building code review for the entire fish process building and ancillary buildings. SMG also procured building permits for these structures. The structural building designs included a wood office building, a wood infeed building, a masonry equipment building and an additional two story steel building. SMG coordinated with many different disciplines including the site civil engineer, USACE permit specialist, mechanical engineers, electrical designer, refrigeration designers, contractors and fabricators. SMG provided design and support services from concept through construction completion for this facility.
Bay Area Bulk Terminal
SMG designed this bulk commodities terminal. The facility receives bulk petroleum coke from trucks, transfers the coke to storage, and then delivers it to Panamax-sized ships. SMG led the design portion of the design/build project. Provisions were made for future phases to receive by rail and ship, and to ship by rail and truck for a variety of bulk commodities. The system is completely enclosed with tubular conveyor galleries and concrete domes to meet stringent air quality requirements. Work included conceptual and feasibility design, civil design, foundation design, mechanical design, structural design, design of support utilities, coordination of electrical and controls design, permitting and on-site engineering coordination.
Replacement Dock for Recycled Steel Handling
SMG designed a replacement dock for a steel recycling company to support a container crane retrofitted to be a bulk ship loader and to support a variety of heavy duty mobile equipment. The concrete deck, steel substructure dock was designed to berth ships and barges. The design included a relieving slab as a transition to the land, used tensioned soil anchors to resist seismic loads, and incorporated the use of existing piles that could be reused. This dock was approximately 660 feet long by 90 feet wide.
Waterview Barge Loading Facility
Columbia City, Oregon
SMG designed a barge loading system and feed conveyors for the Waterview site on the Columbia River. The facility receives aggregate from an adjacent deposit and transfers them onto a barge. The barge loader can telescope and luff to distribute product for efficient barge loading. The facility can load over 2,000 TPH of aggregate. The dolphins and moorage are sized to accommodate a variety of barge sizes.
Port of Portland Terminal 5
SMG designed this bulk export terminal. The terminal is designed to handle a variety of bulk commodities. Up to 100,000 MT of potash is received from unit trains (100 railcars) through a continuous dump rail unloader, and stored in a 160-foot-wide by 1,500-foot-long by 85-foot high corrosion-resistant wood building. The product is automatically reclaimed with twin 4,000 MTPH maximum reclaimers, and loaded to Panamax-sized ships. The terminal is designed with two loop tracks to accept two unit trains at a time. SMG's design work included transfer conveyors for the distribution of the product, specifications for buyout equipment, support buildings and offices, civil and foundation design, support utilities, and dock and shiploader modifications. SMG led the project through the initial feasibility, preliminary design, final design, and provided continuous on-site engineering coordination during construction.
Aggregate Loading Berth
SMG designed, drew, and permitted this aggregate barge loading berth. The berth included mooring and breasting dolphins and slope protection. SMG's services included site investigation and initial layout, design and drawings, and obtaining local municipal and Army Corps of Engineers permits.
Dock Assessment and Repair
SMG was retained to review, assess, and create a repair plan for this existing dock for loading scrap steel to vessels. This dock is a combination of wood, steel and concrete construction. SMG reviewed and assessed deteriorated members and provided replacement and repair plans. The work also involved developing repair schemes that could be constructed in very difficult access and space limitations.
Pipe Pile Driving Template
SMG designed a barge mounted pile lead template to drive production piles to a tight tolerance dictated by the agency for a large scale dam project. The template has four leads with hydraulically actuated guides to accurately position piles in the horizontal axis. The template allowed rough positioning of the barge and fine positioning of the pile without moving the barge. This template accelerated the installation of hundreds of piles placed on this project. This design required both SMG's structural and mechanical capabilities.
Aggregate Barge Unloading System
SMG provided initial layouts, conceptual designs, final design documents, and permit assistance for this aggregate unloading system and conveyance. The design included pile supported receiving system with hopper and conveyor to land-based aggregate storage. This system receives product from a self-unloading barge allowing efficient transport of aggregates from a remote site to the Portland metropolitan area.
Shiploader Bearing Replacement Plan
Long Beach, California
SMG provided structural and construction engineering services to jack a one million pound shiploader up to allow for removal and replacement of a 20-foot diameter slewing bearing. SMG's services included sequence, design of lifting and handling devices, and on-site support during the jacking.
Barge Mounted Mixer Stands
SMG designed barge mounted stands to support four 14-cy concrete mixers mounted on a barge to provide a concrete delivery system for conventional and tremie concrete to be placed for a dam construction on the Ohio River. The design supported the mixers, transferred loads to the stiffened locations of the barge and included maintenance and operation access around the mixers.
