JDS has been involved on thousands of engineering projects in NC and beyond. Please take a look below at some of our work in the fields of retaining wall design, forensic studies, material testing, and structural engineering.

Apartment Complex Project
We performed this structural inspection in collaboration with RB Engineering in Cary, NC. We were asked to address concrete cracking in the suspended slab corridors between units as well as the cantilever bays and foundation cracking and settlement. After a thorough inspection of each unit, the framing, and foundation system we were able to issue a repair plan that saved the client over 150k in repair costs. Our plan included installing new pier lines to re-level the floor framing as well as adding helical piers to the perimeter foundation and bay support areas. Drainage improvement was also required along with replacing some of the structural support beneath the suspended slab corridors which ruptured due to high moisture and overloading.

Audubon Retaining Wall Design & Testing
We were hired to design, test and certify the Audubon Apartments retaining wall in Cary, NC. Our engineering team worked with the supplier and contractor to provide a cost effective and eye-pleasing design. Once construction commenced our field team performed routine inspections to monitor the installation so that we could provide the final certification report for the wall.

Paradise Cove Amenities Center
This is one of our many above grade pre-cast concrete designs the we were contracted to do through Superior Walls of NC. We were provided the architectural plans and the pre-engineered truss plans. It was our task to design the foundation system including the perimeter walls and concrete lintels as well as the slab foundation and interior footing support. The pictures above show the finished amenities center as well as some parts of the installation process. We currently work for Superior Walls of NC for projects all over the region.

Kolarov Project
This is one of our control-fill projects that was performed over a period of about 3 months. The client had a significant amount of fill for the project. We performed proctor testing and soil classification on the fill material to be used on site. The project took a very long time due to the fill material failing spec on almost every field test during the first 2 months of the job. With guidance from our engineers and techs on site the contractor was finally able to get the material installed within specifications.

Whitehead Project
Our clients 2SL Design Build, Inc always provide interesting designs for us to engineer. The Whitehead project was no exception. Due to the dramatic slope on the lot it became clear that in this case it would be more economical to build a steel frame support system with lug footings rather that the traditional masonry or concrete foundation systems used in the area. We are always up for a new challenge and the Whitehead project has turned out beautifully.

Trotter Forensic Investigation
In spring of 2009 the Trotter residence was struck by a large tree that fell during one of our many thunderstorms we get here in Raleigh/Cary. The tree tore through the roof and attic floor framing which was sealed in promptly by a local disaster response crew. Prior to the tree damage there were no issues with excess water penetration in the basement area and upon our initial inspection of the basement no severe cracking could been seen. However, after the tree hit the water kept flowing in regardless of the existing pump system that had been installed years earlier. Our task was to develop and prove a theoretical scenario in which the impact force of a tree could cause a rupture in the existing un-reinforced masonry wall. The main purpose of our analysis was to show the insurance company that this could happen and that the homeowner should not be responsible for the water damage caused after the tree impact.

Fort Bragg Flight Simulator Facility Retaining Wall
We provided structural engineering analysis for a retaining wall of about 80 ft. by 8 ft., comprising modular concrete block units with an inner drainage area. It is located in a naturally marshy area. For this reason, our design called for 8-ft. Sonotubes every eight feet.

Raleigh Marriott Crabtree Valley Retaining Wall
We created a plan for a retaining wall near a bioretention area at Raleigh Marriott Crabtree Valley using the Keystone Standard Unit Retaining Wall System.

Lake Lyfe Homes Soil Compaction Testing
For Lake Lyfe Homes, JDS performed lab testing and observed the placement and compaction of fill material. We determined that the subgrade, testing and compaction met or exceeded ASTM D698 standards.

Del Web Lifestyle Center Structural Design
For the Del Web Lifestyle Center, JDS reviewed the existing plans and provided a life safety plan design and load analysis for compliance with the 2012 NC Building Code.

Olde Stonegate Helical Pier Design
A contractor requested a timber-pile design for a 2,243-square-foot house that would have required nearly 100 timber piles. The client agreed to our practical, alternative design that only used 53 helical piers of higher load capacity.

Southern Industrial Constructors Structural Analysis
JDS provided a structural analysis and review of Southern Industrial's internal rigging designs, and we provided structural engineering services for other new construction and renovation work that the company performed.

Waltonwood Lake Boone Structural Field Analyses
We were hired to perform as-built inspections, as well as to provide truss reviews, analyses and recommendations for the Waltonwood Lake Boone retirement living community.

CalAtlantic Homes Office Code-Compliance Review
JDS provided a code-compliance review for the renovation plans of an office suite within an 83,300-square-foot building at 1100 Perimeter Park Blvd.

U.S. Department of Veterans Affairs Retaining Wall
As part of a larger project to realign Franklin Blvd. and provide parking southeast of the VA Medical Center in Hampton, Virginia, JDS provided structural engineering services for a retaining wall that is 352 feet long with a maximum height of six feet.

Framing Projects Throughout the Southeast
JDS has provided structural inspections, analyses and design for tens of thousands of new and existing residential projects throughout the Southeast.

Bandito’s Restaurant & Cantina Structural Design
JDS provided structural design services for Bandito's Restaurant & Cantina in Myrtle Beach. We designed the precast concrete system and attachments, including attachments to footings and structural steel.

Mebane Vision Center Remodel Structural Plans
JDS delivered structural plans for remodeling a former bank into an eye examination and optical services center, the Mebane Vision Center in Mebane, NC.

Big Bend Solar Array Engineering Review
Working with Sunlink Corporation, JDS provided an engineering review of a Burns & McDonnell report on geotechnical load testing for the Big Bend solar energy installation constructed by Tampa Electric.

Hasentree Sales Center Structural and Building Design
JDS provided structural and building design services for the Hasentree sales center in Wake Forest, NC. These included the floor, roof and deck plans.

West Ellerbee Creek Trail Gabion Wall Design
JDS provided the design for a gabion wall built along an extension of the West Ellerbee Creek Trail in Durham, NC. The wall is designed to be a part of the natural environment and support vegetation. It is located next to a new boardwalk and free expression tunnel.

Haywyck Meadows Amenity Center Building and Structural Design
JDS provided building and structural design for the amenity center, which included plans for life safety, fire protection, floor layouts, the foundation, walls, ceiling framing, wall bracing, plumbing, HVAC, electrical, elevations and parking.
