Tetra Tech INCA provided preliminary and final design for the Sitka Dock. INCA developed alternatives for the shore connections and mooring system; analyzed loads, tidal fluctuations, and wind loads; evaluated and developed alternatives for pontoon reinforcement; and provided siting of the pontoon. Special features included the design of ramp connections using a specially fabricated set of elastomeric and steel bearings for kinetic energy absorption in the event of docking collisions.

This design was named an “Outstanding Example of Excellence in Concrete Construction” by the Washington Aggregates and Concrete Association.

The Rhododendron Trail, a 10-foot wide, 1.6 mile long, paved multi-purpose transportation and recreation trail, begins at the intersection of SR 20 and Main Street in Coupeville and terminates at the intersection of SR 20 and Rhododendron Park Road. The trail begins across Main Street from the end of the Kettles Trail along SR 20 from Main Street and continues with a wide shoulder to accommodate equestrian use. Where existing wetlands were crossed, the trail is served by an elevated bridge and boardwalk structure. INCA prepared plans, specifications and estimates for construction.
 

Tetra Tech INCA provided project management support services to the Washington State Department of Transportation (WSDOT) Northwest Region Real Estate Services (RES) team, assisting real estate agents and management by providing budget monitoring and analysis services for the region’s active and future right-of-way acquisition projects. This support provides the RES Office and Northwest Region Program Management with accurate forecasting of expenditures to better anticipate and react to project changes.

The key features of this project are enhanced communication between RES staff and management on the forecast schedule and budget for right-of-way acquisition projects. Acquisitions were part of the design projects and are key to delivering these projects. In order to accurately plan project delivery at the program level, individual project forecasts and schedules need to be as accurate and up-to-date as possible. The project greatly assisted in overall program forecast.

Tetra Tech INCA provided a complete master schedule and time phased budget plan for the design of a Combined Maintenance Facility and access road to the Facility for Pierce County. INCA’s scope of work included project performance monitoring throughout the life of the design project by using earned value techniques. INCA provided monthly reports on performance to the design and management teams, and expert guidance to the design team on project delivery risks based on the continual performance monitoring.

Key elements provide by this project included:

• Multi project master critical path schedule (CPM) with progress updated monthly
• Budget expenditure plan based on the CPM
• Monthly earned value performance monitoring
• Monthly report of progress in the form of an updated CPM, Milestone chart and earned value charts

The residents of the Lake Hills neighborhood wanted a trail/walkway system running the circumference of Phantom Lake, and connecting the Lake Hills Greenbelt Trail with access to Lake Hills Greenbelt Park on Phantom Lake, and Weomna Park just west of 168th Avenue NE. A bond issue to fund the project was passed, and Tetra Tech INCA was selected to design the trail system and two pedestrian bridges.

The trail, which is approximately three miles long and ten-feet wide, is located in an environmentally sensitive area and affects over 65 parcels of land. The INCA Team and City of Bellevue officials met with property owners, both on an individual basis and by holding community group meetings, to incorporate citizen input into the design and to respond to concerns about noise issues, the potential for vandalism, property damage, and environmental impacts.
