This 30-acre site was master planned for up to four dealerships.  The first phase consisted of a 45,500-sf dealership building a show room, 18 bay shop,  carwash, and 550 vehicle spaces.  All infrastructure was installed to account for future phases including a regional detention pond.  Driveways with decel lanes and left turn lanes were required to provide an access road between all phases that accommodate large delivery trucks. Gravity sanitary sewer was not available adjacent to the site,  requiring OnSite to work with Oconee County, GDOT and the Owner to determine a gravity flow route. The solution was a 21' deep, 400-lf jack and bore under GDOT Hwy 316 in order to reach a sewer basin with capacity for the project. 

A new Mercedes Benz showroom, shop,  carwash, and 450 vehicle spaces were added to this 8-acre parcel.  A large car tower will sit along the interstate to provide visibility from I-85. Car hauler access is provided through the site to allow vehicles to unload internal to the site.  The site is extremely tight, therefore the stormwater detention facility is installed underground and consist of 8’ diameter perforated pipes to allow stormwater to infiltrate and provide runoff reduction.  An 800' sanitary sewer main extension was required to provide gravity sewer service to the property.  Permitting consisted of coordination with Union City, Fulton County, and the City of Atlanta.

Project consists over 9 acres adjacent to the Nissan McDonough site.  Scope included a car dealership building with a showroom, shop, a carwash, and 500 vehicle spaces.  Existing grades and owner requirements required the use of retaining walls to the site to raise the building and provide visibility from I-75.  A “No Rise” study was required to allow for development within the existing flood plain.  Stormwater is routed to a forebay with a water fountain, and then drains into a wet detention pond to meet the water quality and detention requirements.  Decel lanes were required to access the site and large truck routes were provided throughout the site. 

This project location was a vacant outparcel of a Kroger anchored shopping center in the Hickory Flat area of Cherokee County.  The site was controlled by existing development on both sides, steep existing slopes, and multiple utilities crossing the site.  Retaining walls were required to avoid utilities and provide drive thru building access and ADA access from the parking.

The outparcel adjacent to the existing site was purchased to expand the dealership's current building and parking lot. The existing 8,900-sf building was expanded to 18,660-sf. The adjacent building was razed to make room for the building and parking expansion. The new parking area incorporates area for a riding school to help new riders obtain their license.

The scope for this project included a 39,000 sf showroom/shop building, 300 parking spaces with large car hauler routes and car display pads placed around the 13.4-acre site.  The existing GDOT entrance to Buford Drive (GA HWY 20) was reused and  a new second entrance from Plunketts Road was added.  Erosion control practices were designed for multiple phases of construction to protect the adjacent property owner.  OnSite provided a landscape design along with construction phase services to closeout the construction and obtain a Certificate of Occupancy for Ownership. 

This dealership renovation included a new 46,856 sf showroom/shop across the street from the existing dealership.  The existing showroom was razed.  A carwash and an expanded inventory parking lot took its place.  The additional impervious areas were treated by  newly designed stormwater detention ponds.  Sanitary sewer connection to County mains required a new pump station.  OnSite worked closely with the owner, Georgia Power, and GDOT to relocate a Georgia Power Transmission Pole that was too close to the proposed showroom/shop building along Charles Hardy Parkway.   

This project included site clearing, grading and infrastructure design for the construction of a new 24,000-sf Fleet Center for AGL on the same 400 acre campus where OnSite has worked many times before.  The building features 5 dual depth service bays for pull through service access of up to 10 vehicles.  Infrastructure design included a new detention pond for proposed site and future development.  ​​

This project included a new Lincoln showroom building and a standalone shop on the site of an existing Ford dealership.  Steep slopes and close proximity to existing buildings caused ADA and vehicular access into the buildings to be challenging. Stormwater quality requirements were met by using proprietary devices.  Multiple sinkholes were found during construction, and OnSite worked continuously with the contractor, owner, City, and State to provide solutions.
