City of Houston Broadway Street Reconstruction
Houston, Texas

HVJ provided recommendations for the Broadway Street reconstruction project that extended from IH-45 to Old Galveston Road in Houston, Texas - an alignment of approximately 1.7 miles. Project elements included: replacement of waterlines, storm sewers, traffic signals pavement reconstruction, recommendations for the installation of utilities using both open-cut and auguring techniques, as well as recommendations for bedding and backfill, excavation stability, bore stability and groundwater control. An alternative method for subgrade stabilization using water soluble polymers rather than lime was used for this project to assess if it is a faster placement. The research is still in progress, and about 1000 feet of Broadway Street will be stabilized with this polymer after optimizing the polymer percentage. HVJ calculated what the rigid pavement thickness for Broadway Street should be using the DARWin Pavement Design program (AASHTO based Design Procedure). Reinforcement details and subgrade stabilization recommendations were also provided for the pavement.


City of Houston Northbelt Wastewater Treatment Plant
Houston, Texas

HVJ conducted a geotechnical investigation for the improvements undertaken for the Northbelt Wastewater Treatment Plant (WWTP) located at 14506 Smith Road in Houston, Texas. The improvements consisted of rehabilitation and upgrade of the existing lift station, installation of various electrical equipment, and replacement of the existing sodium bisulfite tank and containment area. With data generated from the geotechnical investigation, HVJ provided foundation design recommendations for the new sodium bisulfite tank and concrete containment area. Our recommendations called for a conventionally reinforced slab-on-grade foundation and mat foundation for the proposed tank and containment area and included allowable bearing capacity, modulus of subgrade reaction, floor slab and settlement.


City of Houston Cindy Lane at West TC Jester Boulevard
Houston, Texas

HVJ conducted a geotechnical investigation for the repair of a storm sewer outfall pipe at White Oak Bayou near the intersection of Cindy Lane and West TC Jester Boulevard in Houston, Texas. The repair included replacing a portion of the 66-inch diameter pipe at the bottom of the bayou bank that is approximately 77 feet in length. Challenges faced by HVJ during this project included a large sinkhole near the outfall pipe and unsuitable soils were encountered at the pipe invert depth. The pipe is next to the bayou making control of the groundwater difficult during construction. HVJ provided recommendations for sinkhole backfill, control of groundwater and the foundation base for the pipe.
