Burns Bridge Value Engineering Study
Location: Worcester, MA and Shrewsbury, MA
Services: Value Engineering
Completion Date: 2010
The Massachusetts Department of Transportation (MassDOT) is proposing to replace the Route 9 Kenneth F. Burns Memorial Bridge (Bridge No. S-14-001-W-44-018). The bridge spans over Lake Quinsigamond on the Shrewsbury-Worcester city line and is part of State Route 9, which is very heavily traveled in the project area, carrying approximately 35,000 vehicles per day. The existing concrete open spandrel arch bridge, which was built in 1916, replaced an earthen causeway to allow a passage for water vessels. The preferred alternative will provide a solution that meets the roadway and lake users’ needs, provides an aesthetic structure consistent with the site context, minimizes construction duration by providing opportunities for accelerated construction techniques, and provides a cost effective replacement.
MassDOT initiated this VE study in order to accomplish the project's goals in the most expeditious and cost effective manner. The objective of this effort was to identify opportunities and to recommend alternatives that improve value in terms of capital cost reductions, schedule time savings, improved constructability and product enhancement while providing the basic functional requirements to meet the project intent.
Keville Enterprises conducted this VE study in August 2010. The project estimate ($91M) and the Bridge Type Study Report formed the base documents used by the VE team in its study. The VE Team was given the task of studying a practical and workable design alternative and to provide an independent review in order to identify recommendations that would potentially reduce the project costs and/or time or otherwise add value while maintaining the function, performance, and quality of the original design.
Keville was responsible for providing the VE Team facilitator Certified Value Specialist as well as technical team members, and coordinating the entire effort. Keville also prepared the Preliminary Report, Summary Report, Final Report and compiled the final disposition form for MassDOT management.
The VE Team generated 47 initial ideas of which, 21 achieved the required minimum score, and of which MassDOT endorsed 16 for development.
After the development phase, the VE team concluded that 13 of the ideas could potentially improve the performance of the project and/or reduce construction and life cycle costs. The proposed initial cost savings for these 13 ideas were $10,083,000 with an additional life cycle cost savings of $26,447,000.
The Summary of the VE Study Benefits is as follow:
• recommended VE Ideas – 13
• total number of Design Suggestions – 8
• proposed Cost Saving as % of Const Cost - 11%
• VE Study Return on Investment (ROI) – 220:1
