Seattle Public Utilities
Seattle, Washington
Exeltech served as civil engineer, cost estimator, and constructability reviewer for the development of a planning-level construction cost estimating tool to be used by Seattle Public Utilities and King County Wastewater Treatment Division’s design staff for the preparation of the early “Basis of Estimate” project documents for bioretention design for green stormwater infrastructure projects being retrofitted in City right-of-way. The tool included evaluation of existing conditions for street corridors and the replacement of sidewalk facilities in the project planning estimates.
