Highlands Reservoir Replacement of Basins 1/2

Denver Water awarded Garney this $10 million project that included demolition of two existing 3 MG buried concrete tanks to make way for the new 7 MG D115 internal post-tensioned concrete tank. The concrete from the demolition was crushed on-site and used under the new tank for stabilization material. The new tank was designed to be buried for aesthetic purposes due to the neighborhood setting of the tanks, which is adjacent to property owners on three sides. This urban setting required close monitoring of noise, vibration and dust. This project also included asbestos abatement for the expansion joints of the existing tanks and their associated pipelines. Tie-in of the 300 LF of 30″ and the 100 LF of 42″ steel pipelines were completed during the one-week shutdown period. The tie-ins required 24 foot deep excavations, shoring, cathodic protection, welding and joint repairs. The site improvements included new asphalt roads, landscaping, and 8′ security fencing.

 

Their attention to detail was exceptional, and I contribute this to the quality of work that was performed. Garney Construction showed a continuous effort to be very transparent and communicate any positive or negative issue early, avoiding any surprises with costs or schedule.
