RFP-MMD-0000000002 - Lift Station "A" Gravity & Force Main Proposal

The project Work is located within the limits of the Meridian Metropolitan District of Colorado.
The general area of the project work is bound from Lift Station A, which is located directly west
of Cottonwood Creek and east of Jamaica Street, and extending half a mile east, south of E470,
and north of Meridian Boulevard. The Work generally encompasses construction of
approximately 1,737 lineal feet of new force main and 668 lineal feet of new gravity main.
1. The Work also includes all site preparation and erosion control, earthwork, dewatering,
sanitary sewer bypassing, parking lot restoration, revegetation, and restoration of all existing
facilities and surface improvements to pre-construction conditions. Also included is the
survey and staking as required for construction, and all miscellaneous work as shown and
specified for a complete installation. It is anticipated that some portions of the sewer
improvements will be constructed in wet or high groundwater areas. Construction in wet
areas will require dewatering. Some areas may require stabilization per these specifications.
Actual conditions of surface improvements around this work may differ from what is shown
on the Drawings. It is the Contractor’s responsibility to verify actual field conditions. It is
strongly recommended that the Contractor investigate the site of the work sufficiently to
satisfy themselves of the extent and conditions of the project.
