Memphis International Airport Expansion
Problem: Client had only incomplete underground utility records. Major concerns existed about the location of the underground FAA Fiber Optics and the location of a 16” High Pressure Gas Main thought to be encroaching within the construction limits. The Memphis-Shelby County Airport Authority needed to update 20-year-old records. In addition to the runway expansion, an emergency access road was to be constructed.
Solution: All existing utility companies were contacted and agreed to provide current available information. Coordinating with Kimley-Horn, the design engineer, we created runway closure “windows” to trace all utilities in conflict. At the beginning of the project it was estimated that there were approximately 20,000 feet of utilities, or four lines to identify along the runway corridor. During the project, we found and identified 13 separate utility locations. This included 7 Fiber Optic Cables, 1 Electric Duct Bank, 1-24” Water Main and 2-16” High Pressure Gas Mains. All the utilities were identified, surveyed and incorporated into the Airport Authorities base map. It was determined that approximately 80 Test Holes would be required to identify points of design conflict.
Results: Both the Airport Authority and Kimley-Horn were amazed by the amount of utilities that were within the project limits. They anticipate lower construction bids and shorter construction schedules. The Airport Authority now expects to use SUE on all future design and construction projects.
Problem: North Carolina DOT needed to widen NC 49, an existing 2 and 3 lane Roadway, to 5 lanes. This roadway is one of 2 main arteries that channels traffic from the south into the City of Charlotte. Drainage along the road was a major concern and the utility companies had minimal utility records. The project design scope included a new bridge over Sugar Creek and the design was contingent on the location of a 36” DIP water main and a 24” high pressure gas main. Additionally, NCDOT wanted minimal impacts to the traffic flow during construction. Due to the high traffic volumes and excessive utility impacts, it was decided to use SUE to provide complete utility information.
Solution: A scope meeting was held with NCDOT representatives prior to starting this project to establish project limits. Each utility company provided copies of their records for use on the project. Based on the information obtained from the records, the consultant expected to designate and identify approximately 180,000 feet of utilities. We designated over 230,000 feet of utilities along the 2.8 mile corridor, including a large telephone duct bank through 60% of the project. Sixty points of conflict were identified and Test Holes were excavated for drainage design. The 36” water main and 24” gas main were found under Sugar Creek. Their location placed them directly under the proposed foundation for the new bridge which required each to be relocated.
Results: By using SUE, NCDOT had an accurate map of all the utilities within the construction corridor. They were able to negotiate a lower price for utility relocations. NCDOT saved expensive redesign costs of the Sugar Creek Bridge foundations due to utility conflicts. Contractor bids were 13% lower than anticipated.
Two Notch Rd. (US-1) Reconstruction, SCDOT Pilot Project
Problem: South Carolina DOT needed to widen an existing 2 and 3 lane roadway to 5 lanes. Existing buildings were built up to the ROW Lines. Drainage along the road was a major concern and the utility companies had incomplete utility records. This roadway is one of 3 main arteries that funnel traffic into the City of Columbia. SCDOT requires minimal impacts to traffic flow during construction. It was decided to make this an SUE Pilot Project to provide complete utility information, to the design engineer and the contractor, to shorten the time required for design and construction.
Solution: Meetings were held with all the utility companies prior to TWT starting this project and SUE Policies and Procedures were explained to each representative. Each utility company provided copies of their records for use by TWT. Based on the information obtained from the records, it was anticipated that there were approximately 70,000 feet of utilities to be designated and identified. Most of the Water and Gas Mains were PVC with no trace wire. There was a large Telephone duct Bank throughout the entire construction corridor. TWT designated over 250,000 feet of utilities along the 3-mile corridor. A minimum of 40 points of conflict were identified and Test Holes were excavated for drainage design. The Gas Mains and Telephone Duct Bank were identified. Several Water mains were found that the City of Columbia did not know existed. Results: By using SUE, SCDOT had a complete map of all utilities in the construction corridor. They were able to negotiate a lower price for utility relocations. SCDOT expects minimal to no redesign costs during construction due to utility conflicts. Contractor bids were 15% lower than anticipated.
