Pinnacle Design/Build has successfully designed and constructed hundreds of thousands of earth and water retention structures in support of commercial and retail development projects throughout the United States. Our ability to work with developers and architects to design and construct walls and other structures that are functional as well as aesthetically fitting has allowed Pinnacle Design/Build to become one a preferred specialty subcontractor to service this industry. In addition, we often make design recommendations that substantially reduce the cost of earth retention without sacrificing the developer’s vision for a project.

Pinnacle Design/Build - Commercial/Retail Project Profiles


		Home Depot, Villa Rica, GA PROJECT FACTS: Slope Area = 31,000 SF; Max Ht = 32 FT CHALLENGE: Create a grade separation along the property line to support the new store and parking lot. SOLUTION: Pinnacle Design/Build provided a 32 ft tall Vegetated MSE vegetated slope as a value added alternative. VALUE: The Vegetated MSE vegetated slope was constructed faster and eliminated utility conflicts with utilities adjacent to the slope. The “green” solution allowed the very tall steepened slope to blend into the natural surroundings.

		Marketplace at Birmingham Village, Alpharetta, GA PROJECT FACTS: Wall Area = 17,760 SF; Max Ht = 18 FT CHALLENGE: The commercial developer required the site storm water detention basins to be more cost effective than cast in place concrete. SOLUTION: Our engineers redesigned the detention basin walls from all cast-in-place concrete to a composite vegetated welded wire form /cast in place retaining wall. VALUE: This solution provided 35% cost savings over the previously designed wall and provided more pleasing appearance.

		Home Depot, New Albany, IN PROJECT FACTS: Wall Area = 3,500 SF; Max Ht = 20 FT CHALLENGE: This retail store was positioned into a hillside cut at the rear of this site. The cut required permanent support to allow for the construction of the rear access drive. SOLUTION: A permanent Soldier Pile Retaining Wall with wood lagging was constructed to support the hill side excavation. VALUE: The Soldier Pile Retaining Wall was constructed quickly and allowed for store construction to progress unimpeded.

		Lenoir Business Park, Lenoir, NC PROJECT FACTS: Wall Area = 94,000 SF; Max Ht = 56 FT CHALLENGE: The developer of this project required nearly 100 acres of relatively flat space to construct several buildings and associated parking. The project, located in the hilly region of western North Carolina was on a fast track and the reinforced slopes were on the critical path of the project schedule. SOLUTION: Pinnacle Design/Build engineered and constructed four massive MSE Vegetated slopes that averaged over 38 feet in height. VALUE: Pinnacle Design/Build was able to make engineering decisions during the design and construction process that allowed the grading contractors to move at an expedited pace and stay on schedule. In addition, the vegetated slopes blended nicely with the surrounding area and were less expensive than other options considered.

		Piedmont West, Atlanta, GA PROJECT FACTS: Wall Area = 5,300 SF; Max Ht = 18 FT CHALLENGE: The commercial development required retaining walls to create a below grade stormwater detention pond on a congested construction site with limited right of way. SOLUTION: Pinnacle Design/Build designed and constructed a tied-back soldier pile and lagging walls with a cast-in-place concrete facing on three sides of the structure and a segmental retaining wall on the fourth. VALUE: The Pinnacle Design/Build solution enabled construction of the stormwater detention basin within the limited confines available. The solution provided a substantial cost savings over the originally designed cast in place concrete retaining walls.

		Home Depot, Inverness, AL PROJECT FACTS: Wall Area = 8,000 SF; Max Ht = 37 FT CHALLENGE: The retail site’s extreme change in grade required a retaining wall to support the store’s rear access drive. SOLUTION: A MSE Segmental Retaining Wall was the solution selected by the Pinnacle Design/Build design team for the structural support of the fill for the rear access drive. VALUE: The selected MSE Segmental Retaining Wall system’s high structural performance provided the required support for the 37ft fill while offering an appealing architectural finish.

		Atlantic Station, Atlanta, GA PROJECT FACTS: Wall Area = 23,000 SF; Max Ht = 15 FT CHALLENGE: The developer was required to support an earth fill adjacent to a depressed parking deck. The retaining wall had to allow vehicular traffic to cross over the top of the retaining wall into the parking deck. SOLUTION: Pinnacle Design/Build engineered and constructed a segmental retaining wall with a cap beam. The project’s parking deck structural engineer designed a cantilever road section to span into the upper deck. VALUE: The retaining wall was installed at lower cost than conventional cast in place concrete.

		Lowe's Home Improvement, Henderson, TX PROJECT FACTS: Wall Area = 15,800 SF; Max Ht = 27 FT CHALLENGE: The retail developer had to maximize the useable land on this site to accommodate the new store. SOLUTION: Pinnacle Design/Build constructed both MSE vegetated retaining walls and the MSE segmental block walls along the property edge. VALUE: The retaining wall structures were installed at lower cost than conventional types. The “green” retaining wall blended well with the stream channel.
