Washington State Patrol Light Industrial Facility
Tumwater, Washington
The Washington State Patrol Light Industrial Facilities project was the first of its kind in the state and was the result of six years of effort by the Washington State Patrol to allow for an integrated land swap and design-build construction process within the regulations of the State of Washington. The new WSP facilities in Tumwater, Washington, include three separate buildings, which house approximately 50,000 s.f. of vehicle maintenance, equipping and other industrial applications and approximately 20,000 s.f. of administrative office space. The corollary project, Martin Way Station, was the retail development of the former WSP site consisting of 20 acres in Olympia, Washington.
This project received the “Governing for Results 2002” Quality Recognition Award from the Washington State Governor’s Office.

Satsop Site Restoration
Near Elma, Washington
Osborne Construction Company’s scope of work consisted of performing the design and construction necessary to make the structures functional, eliminate potential safety hazards and demolish several other existing partially completed structures.
Two unique structures were Cooling Towers (CT-3&5). Osborne’s scope of work required the completion of concrete work, seismic repair and installation of a new FAA lighting system on a structure that was 3' thick x 422' in diameter and 500' tall. One of the Reactor Buildings (RB-5) required the installation of twelve concrete wall in-fills. The other Reactor Building (RB-3) required the removal of approximately 1,000,000 pounds of existing rebar, construction of a new parapet wall around the perimeter of the structure and installation of a weather tight roofing system on the existing steel dome roof. These work items were complicated by the fact that the structures were 164' in diameter, 200' tall at its exterior face and 245' deep at its interior face.
The Associated Builders and Contractors of Western Washington awarded this project the “Excellence in Construction” Award for Specialty Construction in 2001.
Eek Airport Relocation
Eek, Alaska
This $2,100,000 project was constructed for the Alaska Department of Transportation at Eek, Alaska. The village is located 60 miles south of Bethel, Alaska on the Eek River close to the mouth of the Kuskoquim River. The project was located in a tundra area underlain with frozen silt, ice lenses and warm permafrost. This area has an active layer in the summer months of 1.5’ to 3’ and has many shallow lakes around the 
new airport location. The material designated to be used for the embankment was a high moisture content silt. These conditions required that the work be accomplished during the coldest part of the year after there was sufficient frost depth to allow haul units to cross the tundra and shallow lakes. Local residents were hired and trained to operate the equipment allowing us to achieve an eighty percent native minority work force. The remote location dictated that all equipment and supplies be barged into and out of the jobsite. The project was started in January and completed in April.
The major items of work on this project were mobilization and demobilization, 350,000 cy of borrow embankment, nearly 10,000 lf of erosion protection berm and approximately 70 acres of seeding.
Mather Memorial Highway
Mt. Rainier National Park
Near Enumclaw, Washington
This $4,667,000 project is located approximately 65 kilometers southeast of Enumclaw, Washington on State Route 410 in Mount Rainier National Park. This Federal Department of Transportation rehabilitation project was the first portion of Phase 1 work to correct structural problems and make safety improvements to the deteriorating stone masonry retaining, parapet and guard walls constructed by the Civilian Conservation Corps in the early 1930's.
The project was completed in just four months. In addition, Osborne Construction Company was required to keep the 
road open to the public from 5:00 p.m. each Thursday thru 5:00 a.m. each Monday. The work was done in two shifts since the contract only allowed five single weekend lane closures with both lanes opened on the remaining weekends for motorists.
This project won the National Excellence in Construction - Infrastructure / Heavy Award from the Associated Builders and Contractors of America.

The Osborne-TIC Alaska Joint Venture constructed the ore-handling and milling facilities for this gold mine near Fairbanks, Alaska. The Scope of work for this $40,000,000 project included installing milling equipment and support utilities, including: a gyratory crusher, a 1/2-mile long conveyor and support framework, 
a semiautogenous grinding (SAG) mill, 2 ball mills, 6 carbon-in-pulp tanks and 2 cyanide detox tanks. Components of this equipment and framework included: 1600 tons of structural steel, 80,000 l.f. of process and utility pipe, 570,000 l.f. of cable, 38,200 electrical terminations, 21,000 l.f. of metal cable support trays, 23,000 l.f. of grounding wire, 5 unit substations, and 42,000 units of connected horsepower.
A part of the mill infrastructure for this gold mine included installation of 6,300 feet of high density polyethylene (HDPE) water and sewer lines and an on-site sewage treatment system, consisting of two septic tanks and two drain fields.
Chulitna River Bridge
Trapper Creek, Alaska
This project involved a complete structural upgrade to the 800-foot Chulitna River Bridge located in Trapper Creek, Alaska. This Bridge is part of the Parks Highway, which links Anchorage with Fairbanks, and was required to remain open to traffic at all times throughout the project.
Two rolling platforms were construed under the entire width of the bridge deck to provide a safe working surface during the extensive structural upgrade.
The new bridge deck included 196 prestressed concrete panels, asphalt paving and slip-formed guard rails.
The site work, sheet piling, demolition of existing bridge deck, concrete work, structural steel, extensive welding work and precast panel installation were all performed by Osborne Construction Company personnel.
Red Dog Mine
Kivalina, Alaska
Portside Facilities
Osborne completed nearly $25 million of Portsite Facilities construction with its own forces for the Alaska Industrial Development and Export Authority. The project is located at a remote site 60 miles Northwest of Kotzebue, Alaska. All construction materials and equipment had to be transported to the jobsite via air or sealift.
The dissimilar stratified rock formations underlying this structure required the development of special techniques for drilling, placement, pressure grouting and post tensioning of 500 foundation rock anchors.
Formwork for building foundation. A C.S. Johnson Model 524 portable batch plant was utilized to batch more than 5,000 c.y. of concrete on site.
Concentrate Storage Building
The lead and zinc Concentrate Storage building structure is 214 ft. in width by 1,425 ft. in length clearspan and rises to a height of 135 ft. This building covers more than seven acres and required the installation of 540,000 s.f. of specially fabricated roofing and siding.
Fort Yukon Bank Stabilization
Fort Yukon, Alaska
This unique project involved construction of nine flood control dikes at Fort Yukon, Alaska. Built for the USDA Soil Conservation Service, this $1,900,000 job was constructed during the winter of 1992 to prevent spring thaws from further eroding the river banks and destroying the Fuel Tank Farm. Winter mobilization of this project required airlifting over two million pounds of armored block, two dump trucks, two hydraulic excavators, five heavy duty pumps and a D-8 Dozer to Fort Yukon, Alaska, from Fairbanks, Alaska.
USCG Loran Stations
States of WA, IN, NV, CA
Osborne Construction was awarded a contract with the U.S. Coast Guard, which included upgrades to five Loran station sites in the continental United States as follows: George, Washington; Dana, Indiana; Fallon, Nevada; Searchlight, Nevada and Middletown, California. The new transmitter buildings, which are approximately 2,211 s.f., house new solid-state transmitters for the Loran signal. The projects consisted of standard foundations, architectural precast concrete walls cast off site, and a hollow core plank roof structure capped by an upside down Irma roof system. The interior is a painted structure with access flooring. Air conditioning and electrical systems were required to accommodate the new equipment including two new UPS systems. In addition, all metal components had to be welded to an extensive network of grounding radials.
As general contractor, Osborne Construction Company’s management team worked closely with the Coast Guard and their design team to coordinate customer changes. The projects have been completed in less than four months with no interruptions to the existing facilities.
The Seattle office of the U.S. Coast Guard rated each of the five Loran station projects with “Outstanding” Performance Evaluations.
