The project is a controlled access four lane divided interstate facility including three interchanges and incorporating 12 bridges. This project also includes roadway improvements to US Route 25, SC 126 (Clearwater Road) Road S-33 (Ascauga Lake Road) and various secondary and local roads. This project is located in Aiken County, South Carolina. Coleman-Snow Consultants is responsible for coordinating all Utility Coordination and relocations.CSC provided utility companies with design plans and determined the companies’ requirements for the relocation of their facilities. CSC researched prior rights for each Utility company facilities and reviewed all Relocation Sketches and Utility Agreements to ensure that relocations complied with the Department’s policies. Coleman-Snow is to survey the final location of all utilities on the as-built drawings for this project. We are responsible for developing the Mainline Pavement Marking Plans as per SCDOT standards and requirements and the final roadway as-built drawings of final field conditions. Value Engineering will be provided for Utility impact avoidance as needed.
This project consisted of the widening of US 278 from near Road S-7-474 (Simmonsville Road) to a point beyond Fording Island Road Extension. The overall project length was 4.955 miles in Beaufort County, South Carolina and was completed in November 2006. Coleman-Snow Consultants, LLC managed the project and integrated our inspection forces with SCDOT personnel coordinating with the Assistant Resident, Resident Construction Engineer and other SCDOT personnel appointed by the State. CSC participated in construction conferences, project coordination meetings, utility coordination meeting and final inspections. Coleman-Snow provided surveying, construction management, construction engineering inspection, and design services throughout the entire project . Mr. Coleman provided public and media relations to local governments, newspapers, news networks, civic groups and other agencies as directed by SCDOT and the Resident Engineer.
This project consists of improving the safety on a 22-mile segment of US 17 from US 21 in Gardens Corner to SC 64 in Jacksonboro, in Beaufort and Colleton counties, while preserving community values and protecting the natural and scenic environment of the ACE Basin. A grade separated interchange is being proposed at the intersection of US 17 with US 21 in Gardens Corner due to anticipated future traffic volumes. The 22plus-mile project is primarily proposed to be a four lane divided primary facility including one interchange and incorporating seven bridges. This project also includes limited roadway improvments to US Route 21, SC Route 303, SC Route 64, and various secondary and local roads to accommodate the widening.
The Project consists of widening the existing two lane roadway section with open ditches to a three lane roadway with dedicated left turn lanes, curb and gutter with planted raised medians, and a closed drainage system. This project is located in Beaufort County, South Carolina on Hilton Head Island and is approximately one mile in length. Mathews Drive intersects US 278, the highest capacity roadway on the Island. Coleman-Snow Consultants is responsible for coordinating all utility relocations. CSC provided all utility companies with relocation plans and provided a two month widow to relocate their facilities prior to the contractor mobilizing to the site. Coleman-Snow performed a constructability review on the original design and assisted the Town in obtaining the SCDOT encroachment permit. CSC provided a full redesign of the project saving the Town of Hilton Head over $750,000 with a Value Engineering concept that was approved and implemented. We are providing construction management and all inspection related services including material sampling and testing for the entire project. Coleman-Snow is providing all quality control and quality assurance measures as necessary to ensure the contractor is building the project in accordance with the plans, specifications, and contract documents.
The Project consisted of providing a roundabout at the existing intersection of Squire Pope Road and Gumtree Road. This project is located in Beaufort County, South Carolina on Hilton Head Island and is approximately 0.4 miles in length. Coleman-Snow Consultants redesigned the multiuse path pavement structure saving the Town in excess of $20,000. CSC assisted the Town in acquiring necessary permits from SCDOT, DHEC and OCRM in order to construct the project. Property boundary surveys were performed for required drainage easements on private property. CSC was responsible for coordinating all utility relocations. We provided construction management and all inspection related services including material sampling and testing for the entire project. Coleman-Snow provided all quality control and quality assurance measures as necessary to ensure the contractor built the project in accordance with the plans, specifications, and contract documents.
The Project consists of designing an interchange along I-20 at S-105. The project is a controlled access facility and will be designed to accommodate either a diamond or partial cloverleaf configuration. The project is located in Aiken County, South Carolina. Coleman-Snow Consultants will be responsible for developing the roadway plans, drainage plans, erosions control plans, traffic control plans, pavement marking plans, and signing plans as per the SCDOT design standards. Geotechnical investigations will be performed in order to classify the material on site and in order to develop a pavement design. CSC will obtain all necessary construction permits and will oversee the environmental process and the Interchange Justification Report. CSC will be responsible for acquiring all right-of-way and coordinating with SCDOT and the Federal Highway Administration.
This project consists of the construction of US 301 bridge over Jeffries Creek. It is Value Engineering encroached on a parcel of land belonging to the City of Florence's sewage treatment plant. Directly in the path of the foundation were three sewer lines of significant size, all with prior rights and a sizeable relocation cost. Engineering investigations revealed that based on the flood elevation, the bridge could be significantly lower. At the same time, lengthening the bridge would move the end bent location and would leave the sewer lines in a space between the last two bents. This was presented as a Value Engineering proposal to the District 5 construction personnel. Since not relocating the sewer lines could potentially save the project hundreds of thousands of dollars, they agreed with the concept and gave the approval to the proposal. CSC produced a full set of roadway drawings for a redesigned vertical profile that met SCDOT design parameters and avoided relocation of major utilities. We saved the City of Florence $855,150.48 through value engineering on the entire project.
The Project consists of providing the Quality Control construction engineering inspection and testing for the Kenzie Park Subdivision located off of SC 46 in Bluffton, SC. Coleman-Snow Consultants participated in construction conferences, project coordination meetings, utility coordination meetings and final inspections. CSC to monitor contractor compliance with all contract documents, technical specifications and special provisions. Coleman-Snow inspected all earthwork, drainage, aggregate base course densities, and surface course placement, and storm drain compaction.
