Project Name/Location: Sand Hill Power Plant Maintenance Facility, Austin, Texas Project Description:

The City of Austin’s energy department, Austin Energy, was in need of a maintenance facility to support its newest power plant. Austin Energy dedicated the Sand Hill Energy Center in eastern Travis County on July 11, 2001. The Sand Hill Energy Center is located in a remote area next to the South Austin Regional Wastewater Treatment Plant on Fallwell Lane off of State Highway 71. This project is the first peaking facility of its kind in Texas to be constructed with selective catalytic reduction pollution control equipment that reduces the nitrogen oxide emission (NOx) rate by 80 percent. NOx emissions from the units are 5 parts per million (ppm), considerably less than allowed under state and federal regulations. The facility's four peaking units provide180 megawatts of electricity to meet the needs of the Austin community during periods of high-energy demand.

Work Performed:

Provided civil engineering services by producing the site plan construction design drawings. Project scope consisted of hydrological and hydraulic analysis for the site, erosion control, site grading, and site paving to best compliment the proposed conditions to the existing contours, while still satisfying the City of Austin’s special needs for the power plant maintenance facility. Calculated construction plan quantities and produced a construction cost estimate for the project.
