Pinnacle Design/Build has successfully designed and constructed hundreds of thousands of earth and water retention structures in support of multi-family and residential 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 - Multifamily/Residential Project Profiles


		Village of Greenway, Chattanooga, TN PROJECT FACTS: Wall Area = 3,000 SF; Max Ht = 18 FT CHALLENGE: The developer of this senior living community needed retaining walls to support a roadway lake crossing into the development's common area. Aesthetics were of particular concern as this crossing was to form the center-piece of the community. SOLUTION: Pinnacle Design/Build engineered and constructed a large span culvert and covered it with back-to-back MSE Segmental Block Retaining Walls incorporating decorative exterior columns. VALUE: Pinnacle Design/Build's solution provided structural stability and aesthetic appeal at a significantly reduced cost compared to a bridge or other comparable systems by combining MSE technology and superior craftsmanship.

		Woodlands of Knoxville, Knoxville, TN PROJECT FACTS: Wall Area = 33,700 SF; Max Ht = 62 FT CHALLENGE: The developer of this high-end college condominium complex had to create useable from the side of a steep hill through the use of retaining walls. Moreover, the highest wall on the site had to support a storm water detention basin with very little tolerance for settlement. SOLUTION: Pinnacle Design/Build designed and constructed several MSE stone faced retaining walls to create the space and structural support required. VALUE: The Pinnacle Design/Build solution offered significant savings when compared to other types of retaining walls considered for this site. Our solution also reduced the time required to bring the site to “pad-ready” condition.

		Stonewyck Detention Basin, Alpharetta, GA PROJECT FACTS: Wall Area = 5,000 SF; Max Ht = 20 FT CHALLENGE: The residential developer for this project required a storm water detention basin that was more cost effective and aesthetically pleasing than the continuous cast in place concrete wall originally designed for the project. SOLUTION: Our engineers redesigned the detention basin wall from a single large cast-in-place concrete wall to a composite segmental retaining wall/cast in place concrete retaining wall. We constructed the concrete wall first then butted the segmental retaining wall into it. VALUE: This solution provided 25% cost savings over the previously designed wall and provided more pleasing appearance.
