Past Performance - Underground Utility Construction

Carr House Waterline Repair

Project Description

This project was located at Carr House in the Huachuca Mountains of the Sierra Vista Ranger District of the Coronado National Forest. Carr House is accessed from Arizona Highway 92, approximately 2.3 miles onto Carr Canyon Road on Forest land. Due to a Monument fire, the watershed which feeds the stream next to Carr House was severely denuded, stripped of tree foliage, shrubs and ground cover. Monsoon storms struck the areas affected by the fire which resulted in extreme flows of water, rocks, boulders and debris that traveled down stream. These flows caused roughly thirty feet (30’) of the main HDPE waterline to become exposed where it crossed the stream.  

Scope of Work

West Point Contractors was contracted to excavate, repair and rebury approximately one hundred and twenty feet (120’) of new 2” HDPE waterline at a depth of 8’ from the existing stream bed elevation. The new waterline was to be installed in 6” bedding of 1⁄4” minus material. The same material was to be used to shade and cover the waterline 8” deep. A combination of native rock and concrete was to be placed over the shaded waterline to help armor the waterline against future flows. Additional work under this contract consisted of furnishing all labor, tools and equipment to install the waterline including trench excavation, shoring, pipe bedding, valve boxes, valves and backfill, flushing, testing and disinfecting the waterline.

Project Challenges

  • Managed multiple suppliers, vendors and subcontractors
  • Effectively managed on-site personnel meeting high quality and safety standards along with effective tenant relations
  • Simultaneous management of multiple phases with multiple disciplines and schedules.
