Subsurface Utility Engineering for Highway Construction

摘要

Subsurface Utility Engineering (SUE) reduces unnecessary utility relocations, unexpected damages of existing utilities, miss-locations of utilities, change orders and claims, personnel injuries, negative factors for productivity, social and environmental damages, and other problems related to utilities through accurate underground information. The benefits are combined with subsequent savings in time and cost for whole projects. Considerable previous research has shown that using SUE can save money on projects involving underground utilities. This paper describes a benefit-cost analysis (BCA) that quantifies the cost savings of SUE with projects developed in Pennsylvania. This study uses both SUE projects and non-SUE projects to quantify the cost savings of SUE on highway projects. This study focuses on a detailed benefit-cost analysis performed on twenty-two SUE projects and eight non-SUE projects.
