Public Works Wall Design & Construction

PROJECT FACTS:  Wall Area = 6,000 SF; Max Ht =  33 FT

CHALLENGE:  The new Lake Fork Pump Station under construction for the City of Dallas required retaining walls at the water intake structure.  When in service, the bottom 2/3 of these walls would be submerged and subject to water level fluctuation as well as wave action.

SOLUTION:  Pinnacle Design/Build designed and constructed a large block MSE retaining wall as a value engineering alternative to massive cast-in-place concrete retaining walls.

VALUE:  The engineered solution yielded a 30% to 40% cost savings over the original cast-in-place concrete design while providing the structural stability required and improving the aesthetic appeal.

PROJECT FACTS:  Wall Area = 10,500 SF; Max Ht = 29 FT

CHALLENGE:  The Mallory Valley Utility District in Williamson County, Tennessee required two new five million gallon water tanks as part of a large public water supply improvement project. To meet elevation requirements, the tanks were to be situated near the top of a  steep hillside. However, a stable and level foundation was necessary to support the heavily loaded tanks.

SOLUTION: 

Pinnacle Design/Build designed and constructed two mechanically stabilized earth segmental retaining walls to safely carry the anticipated loading associated with the tanks.

VALUE:  The Pinnacle Design/Build solution provided a quick and cost effective solution to develop the foundation area required for the new water tanks and allowed the project to  continue on schedule.
 

PROJECT FACTS:  Slope Area = 3,000 SF; Max Ht =  10.5 FT

CHALLENGE:  As part of a City of Houston Parks jogging and bike path improvement project, retaining walls were required at new bridge structure to be constructed over the Buffalo Bayou drainage channel.  These walls needed to provide structural support for the bridge, protect the bank of the bayou from erosion and fit with the natural surroundings of the park.

SOLUTION:  As part of a City of Houston Parks jogging and bike path improvement project, retaining walls were required at new bridge structure to be constructed over the Buffalo Bayou drainage channel.  These walls needed to provide structural support for the bridge, protect the bank of the bayou from erosion and fit with the natural surroundings of the park.

VALUE:  The Pinnacle Design/Build solution provided a surprisingly cost effective and green solution that satisfied city officials as well as park goers.
