INFORMATION/BACKGROUND
The Underwood Substation is a City Council-approved project in Denton Municipal Electric’s (DME)
Capital Improvement Plan. A contractor is required to prepare the site before the start of construction. The
Underwood Substation site will require several site preparation activities including clearing, stripping,
import, export, cutting, filling, grading, compaction, and installation of a concrete retaining wall to structure
the site following the engineered project grading plans. In addition, the Contractor will be required to make
drainage improvements including extending storm drains past the site and installation and maintenance of
the stormwater pollution prevention plan (SWPPP) as directed.
CSP #8419 was prepared to solicit proposals for the site preparation and retaining wall construction to be
awarded to one contractor. Proposers are allowed to utilize subcontractors for parts of the work (i.e.
concrete retaining wall, SWPPP, etc.), but a majority of the work must be performed by the proposer.
