This is a Geotechnical Report prepared for the City of Houston in support of the Waterline Replacement project in the Dissen Heights and East Lawn Area. The report provides subsurface investigation findings and geotechnical analysis necessary to inform the design and construction of approximately 43,817 linear feet of new water main pipelines ranging from 6-inch to 12-inch in diameter. The project encompasses associated infrastructure including valves, fittings, fire hydrants, service connections, pavement restoration, ADA-compliant curb ramps, sidewalk improvements, tree protection measures, and stormwater pollution prevention controls. The geotechnical investigation documents soil conditions, groundwater elevation, bearing capacity, and other subsurface characteristics critical to proper installation and performance of the waterline system in the project area.

The geotechnical findings and recommendations presented in this report establish the technical foundation for bidders to develop accurate construction methodologies, material specifications, and cost estimates for the waterline replacement work. The report's subsurface data and engineering analysis inform decisions regarding pipeline trench design, excavation requirements, dewatering considerations, and construction sequencing in the Dissen Heights and East Lawn Area. This technical documentation enables qualified contractors to understand site conditions and associated construction challenges when preparing bids for the City of Houston's water distribution system improvement project.
