PROJECT NOTICE/JUSTIFICATION: This project was part of the Capital Improvement Plan which constructed storm drainage improvements to address and reduce the risk of structural flooding. Improvements included modification of street conveyance and sheet flow, and detention as needed for mitigation.
DESCRIPTION/SCOPE: The project included the construction of approximately 7,000 linear feet of various size storm systems on Braesmont Drive and the intersecting side streets of Checkboard Street, Kit Street, and Oasis Drive. The proposed storm sewer system included new manholes and inlets. The existing concrete paving, curbs, sidewalks, wheelchair ramps, and driveways within City of Houston right-of-way were removed and replaced. The project also included the construction of approximately 13,000 linear feet of 8 to 15-inch sanitary sewer line, including all appurtenances and 1,000 linear feet of 8-inch waterline within the project area. TRW Engineering designed the project with 365 calendar days allowed for construction. The project was awarded to SER Construction Partners, LLC with an original Contract Amount of $7,738,858.54.
LOCATION: The project area is generally bounded by South Braeswood Boulevard on the north, Lymbar Drive on the south, Chimney Rock on the east and Atwell Drive on the west. The project is located in Key Map Grids 531T and 531X.
CONTRACT COMPLETION AND COST: The Contractor, SER Construction Partners, LLC, has completed the work under the subject Contract. The project was completed on time with an additional 15 days approved by Change Order No. 3.
