- Description
- The scope of work for this construction contract is as follows: (1) Install two (2) pre-cast reinforced concrete manholes. These manholes are for access to the existing 30 diameter by 2400 feet long relief well and toe drain corrugated metal collector pipe (CMP) at Cherry Creek Dam. This pipe is situated 12 feet to 30 feet below grade on the downstream slope of the Cherry Creek Dam embankment. The depths of the manholes are 15 feet and 30 feet. Estimated earthwork quantities are 2500 cubic yards of excavation and backfill. The installation of sheet piling will be necessary for temporary shoring during excavation. (2) Remove all sediment and flush the inside of the 30 diameter relief well and toe drain CMP collector pipe. The length of this pipe is 2400 feet and varies between 12 feet to 30 feet below grade. Access to the pipe will be provided by the 2 newly installed manholes and 1 existing manhole. It is estimated between 150 and 200 cubic yards of material will be removed from the pipe and disposed of offsite. The Contractor can expect accumulated hard packed sediment in the pipe up to a thickness of one-third to one-half the depth of the pipe. The pipe will need to be flushed clean with water, brushes, etc. to facilitate a thorough inspection. Down-hole packers will need to be installed in 14 adjacent relief wells during flushing operations to prevent sediment from fouling these wells. (3) Conduct a thorough downhole camera inspection and document the condition of the 30 diameter relief well and toe drain CMP collector pipe. The length of this pipe is 2400 feet and is 12 feet to 30 feet below grade. Access to the pipe will be provided by the 2 newly installed manholes and 1 existing manhole. The camera equipment shall be a high resolution color camera and pose pan and tilt capability for inspection at right angles to the camera with 360 degree rotation. The entire circumference of each joint will be inspected and videotaped for each outfall pipe from the relief wells and toe drain system (17 total) which penetrates the collector pipe. The Contractor shall provide a digital recording of the entire inspection and a written report along with digital photographs of significant defects of the pipe. (4) A gravel road will need to be constructed at the toe of the downstream slope of the embankment for access to the relief wells/ toe drain collector pipe system. This road will require a top width of 12 feet and be approximately 2000 feet long. It will be constructed of earthfill with 6 gravel surfacing. Estimated quantities are 1500 cubic yards of earthfill and 800 tons of gravel surfacing. Fill material will be imported from offsite for this project. Once the job is done, the road will remain in place for project use. Questions concerning this Sources Sought should be made to Twila Hopkins at 402-995-2070 or email: twila.a.hopkins@usace.army.mil. Telephone calls regarding Small Business matters should be made to Hubert J. Carter, Jr. at (402)995-2910.
