RELOCATION DESIGN FOR A MINOR ARTERIAL STREET. Construction drawings and supplemental technical specifications for a minor arterial street were prepared for a Utah municipality. Plan and profile design drawings were prepared in accordance with Utah Department of Transportation standards to relocate a 1 mile section of a 4 lane, 106-foot wide right-of-way street. The project included horizontal and vertical geometric design, public and private utility relocation design, design of drainage and storm sewer systems, design of pre-cast bridging structures, intersection design, and fencing. Right-of-way instruments and construction easements were also prepared. Flexible pavement design was accomplished for the roadway following the completion of geotechnical evaluations. These evaluations included test pit excavation and logging, soil sampling and analysis, and traffic loading projections. Construction management and inspection were also provided as part of the project.

ROADWAY EXTENSION EVALUATION. EarthFax was requested by the developer of a 1,700-unit residential subdivision to serve as an independent party in evaluating and resolving discrepancies between original project mapping, and design and construction drawings for a new roadway under construction in northern Utah. Control surveying and cross-sectioning was performed at 50 foot intervals along a 2-mile stretch of the rough graded 6-lane highway. Following compilation and evaluation of the resulting field survey data, comparisons were made between existing construction drawings and field conditions with respect to drainage structures, utilities, horizontal alignments, and vertical alignments. Results of the evaluation were used to rectify the above-mentioned differences.

FLEXIBLE PAVEMENT DESIGN. Flexible pavement designs were prepared for a collector road and a minor arterial road for a Utah municipality. The geotechnical investigation for the pavement design included test pit excavation and logging, soil sampling and analysis, and evaluation of existing soil conditions and proposed construction materials. Traffic counts and vehicle distribution analyses were performed to supplement city traffic model information and to establish traffic loading parameters for the pavement design. Supplemental technical specifications were also prepared.

DESIGN OF A WASTE-ROCK AREA ACCESS ROAD. An access road was designed into a proposed waste-rock disposal area for a coal mine in east-central Utah. The road included both asphalt and gravel-surface portions. Geotechnical investigations were performed to delineate foundation conditions. In addition, stream crossings and road drainage systems were designed. Horizontal and vertical geometric designs were prepared for the road based on the design loads, haulage frequency, and other design constraints.
