2-Northside Drive HROM CPN 106170 Project Manual.pdf

This is a Project Manual for a public works project undertaken by the City of Fort Worth, Texas, involving the improvement of an existing storm drain system associated with Northside Drive between Cold Springs Road and Mercado Drive. The project, designated as City Project No. 106170 and HROM CPN 106170, addresses a severely incised ditch resulting from an inadequate 24-inch Reinforced Concrete Pipe (RCP) outfall that is experiencing erosion and undermining. The scope of work includes replacing the existing 24-inch RCP with a 48-inch diameter RCP over approximately 338 linear feet, installing additional lateral piping (56 linear feet of 42-inch RCP and 98 linear feet of 24-inch RCP), removing and replacing 727 square yards of concrete paving with 11-inch concrete paving, installing medium 12-inch stone riprap over 58 square yards, upgrading curb and drop inlets to larger capacity structures, installing storm junction boxes and precast safety end treatments, and completing approximately 1,703 cubic yards of excavation with 340 cubic yards of fill material. The project also involves removal of 25 trees and protection of 30 trees, replacement of pavement markings and raised markers, and replacement of 34 square yards of concrete median. Environmental compliance includes a Stormwater Pollution Prevention Plan covering less than one acre.

The Project Manual serves as the technical and contractual framework for the construction work and includes detailed specifications, drawings, and contract requirements necessary for bidders to prepare responsive proposals. The project is funded through the City of Fort Worth's public works budget and represents a critical infrastructure improvement to address ongoing erosion and drainage deficiencies in the area. All work must comply with applicable Texas construction standards and local municipal requirements, with particular attention to environmental protection measures and traffic management given the project location on an active roadway.
