Design Build (DB)
SCE is dedicated to ensuring our clients receive the best value possible with every project regardless of size. Our experience has proven that opportunities exist for costs savings during all phases, from schematic design through construction. We implement VE measures in each project we design, and regularly provide consultant services as value team members. Our experience and multi-disciplinary approach allow us to quickly understand project goals, constraints, and to offer constructability review and value analysis services that have a track record of added value to our clients.
The VE process allows it to transcend project typology. Most successful when conducted during the end of the schematic design phase, it helps the owner and design team validate the project goals are being met within budgetary and schedule constraints. The “brainstorming” phase is an invaluable instrument where the team states observations and identifies opportunities to reduce cost, improve function, reduce risks, reduce overall schedule, etc. These ideas are then evaluated by team members and narrowed to reasonable level for further development. All observations and ideas generated during the session are shared with the owner and design team with a clear indication of which the VE team believes will add the most value. This allows the design team an opportunity to request further development of an idea not scheduled to be developed as a chance to head off ideas they’ve previously found unviable.
design build projects
Sequim City Hall
SCE was the civil engineer and surveyor of record on this design-build team with Lydig Construction and Integrus Architects for this 35,000 gsf including 43 city staff and public parking stalls, street frontage, and public plaza. Our team won the work competing against three other teams as part of a series of workshops and presentations to City staff and elected officials. SCE completed a full topographical survey and utility survey of the site and permitted all site civil works associated with this 2 acre site in the core civic area in the City Sequim and adjacent to the Clallam County Transit Center. SCE engineers have worked closely with City staff, PUD, and Transit representatives to arrive at an agreeable and sustainable design with LEED silver certification goals. Occupancy was 2015.
The SR99 Bored Tunnel Project replaces the Central Waterfront Section of the Alaskan Way Viaduct. As team members to the STP-JV general contractor, SCE is currently serving as the utility civil/structural engineer. This project is a fast track Design-Build. SCE is performing the engineering design, supporting the contractor to relocate the Seattle City Light (SCL) 115kv, 26kv, and the 13.8kv network services, water main design for temporary relocation, PSE and other utility temporary or permanent relocations to clear the way for the excavation of the open cut and bored tunnel, at both north and south portals. This effort has required close collaboration with the utility contractor, SCL, WSDOT, and SDOT as is typical with Design-Build projects. There are significant de-construction and reconstruction elements to this project requiring special attention to phasing of the work. Construction began in March 2012 and will continue until 2018. SCE is also supporting the settlement monitoring of the excavation and tunneling of this project as a sub-consultant to Sol-Data Incorporated, an expert construction deformation monitoring firm with strong international experience. SCE is performing the professional field surveying; providing vertical and horizontal control, the field survey monitoring and engineering services throughout the excavation and boring of the tunnel for the duration of the project.
RACON Water Supply and Recharge system reconstruction
SCE was the civil engineer for this 1800 LF of water main supply-distribution replacements by utilizing trenchless technologies. Larkor and Buno construction were our partners in this design-build competition and later in the execution of the project. SCE was able to develop a strategic phasing of the replacements by means of pipe-bursting methods and achieve the desired results by meeting NAS tight shut down schedule to minimize the impacts to the water supply-distribution requirements to the base. SCE produced the site topographical and provided the construction survey. SCE worked closely with the City of Oak Harbor Water system to meet their design requirements. Ultimately, the design-team was able to replace the 20″ and 10″ Asbestos Concrete Pipes and the concrete drain systems with field-welded HDPE, which by their inherent material characteristics and improved friction coefficients exceeded the capacity and longevity of the existing and aging system.
