The City of Atlanta, Georgia Prime Engineering has a long-standing relationship with the City of Atlanta, providing civil and surveying services for some of the City’s highest-profile projects. Examples include: Success Story: Consolidated Rental Car (CONRAC) Facility Hartsfield-Jackson Atlanta International Airport’s Consolidated Rental Car (CONRAC) Facility, scheduled for completion in 2009, will house 12 rental car agencies on a single 90-acre site. By centralizing all facilities in a single location, the airport will provide efficient and convenient service to the nation’s fourth-largest rental car market while allowing the airport to expand. An automated people mover will connect the facility to the airport terminal, providing quick access for travelers. Prime Engineering, Inc. is providing surveying, geotechnical, and civil engineering services to analyze, design, and develop the 90-acre property slated for the facility’s location. Specific tasks include: Boundary and topographic survey: Prime Engineering determined the CONRAC site’s boundaries and prepared record documents to establish property lines. Prime confirmed the adequacy and accuracy of existing contours and planimetric features.  Underground utilities investigation: Prime Engineering located and identified existing utility sizes, materials, lengths, and activity levels of underground utilities including sewer and drain lines. Upon doing so, Prime prepared and updated reference drawing files to show utility type and location. Geotechnical investigation: Prime compiled and presented data for use in evaluating rock excavation, pavement design, and design parameters for retaining walls. Permit Requirement Study: Prime Engineering conducted a study to determine required permits/approvals from various jurisdictions.  Civil/site engineering: Prime is creating schematic designs/design development documents for various features such as a stormwater collection system, sanitary sewer, and detention pond. Prime is also conducting mass grading and drainage, performing construction staking, and developing site cross-sections. As these tasks are completed, Prime will develop construction documents, assist in permitting, and perform construction administration tasks. Success Story: Hartsfield-Jackson Atlanta International Airport - Apron Replacment 1, 2, 3, 5, and 9 Prime Engineering is currently undertaking the second of two projects to replace apron taxiway pavement at Hartsfield-Jackson Atlanta International Airport. In total, more than a million square feet of pavement has been or is being replaced. The initial project entailed developing temporary aircraft movement and parking plans; conducting planning and coordination meetings with air carrier and airport operations staff; and preparing construction drawings and specifications to replace pavement on two major airfield ramps. The 15-phase construction project, which featured an innovative new pavement design and a project schedule designed to minimize airfield disruption, was completed three months ahead of schedule and $1.6 million under budget.  Prime implemented a pavement design technique that replaced the existing two-layer pavement (22 inches thick: 16 inches of Portland Cement Concrete [PCC] atop 6 inches of Cement Treated Base [CTB]) with a one-layer composition (22 inches of new PCC) atop 6 inches of soil-treated subgrade. Not only was this replacement pavement design sturdier than the original pavement composition—thereby reducing airfield debris and ongoing maintenance—but it also reached its strength more quickly, drastically reducing construction time. Additionally, as part of the renovation process, Prime Engineering replaced the entire underdrain system for the new aircraft taxiways, further extending the pavement lifespan. To avoid hindering airport operations due to ramp closures, Prime divided the pavement replacement project schedule into 15 phases, allowing all but small sections of the ramps to remain open and causing a minimum number of passenger loading gates to be closed during construction. Construction work occurred on a 24-hour-per-day, 7-day-per-week basis, with minimal disruption to airfield operations. This phased construction plan proved to be very successful. Efficiency in operations and scheduling allowed the project to be completed in approximately six days per project phase instead of the allotted 15 days. The end result: A model for planning, engineering, and executing aviation projects on a vast scale. This model was so successful that the second project— replacement of pavement on Ramps 2, 3, 5, and 9—is following the same process. “Prime Engineering, Inc. was responsive to our needs. They were available 24 hours a day, 7 days a week to answer questions. The design documents were concise and accurate. They met scheduled delivery dates (100% of the time) while staying in budget. Construction phase went smoothly due to the project manager’s hands-on involvement in the design and construction phases.” Quintin B.
