Site work and paving for a mixed-use development in Saint Paul, Minnesota. Completed plans call for site work for a sidewalk / parking lot; for paving for a sidewalk / parking lot; and water / sewer project.

Construction Services for site improvements at the Gortner Lab East Loading Dock, located on the St. Paul campus. Refer to the Request for Proposal documents (found in the Attachments tab) for full project details/requirements. Site / Project Description The proposed project consists of the construction of a new fire lane/access road along Gortner Avenue at the St. Paul Campus of the University of Minnesota. NTI also understands the construction of the proposed fire lane will include construction over top of an existing tunnel. The proposed fire lane is intended to support a fire truck with a gross vehicle weight of 80,000 pounds and a rear tandem axle weight of 60,000 pounds, without damaging the steam tunnel. 2.2 Scope of Services The purpose of this report is to present a summary of our geotechnical exploration and provide generalized opinions and recommendations regarding the soil conditions and design parameters for founding of the project. Our scope of services was limited to the following: 1. Explore the project subsurface by means of 2standard penetration test borings extending to depths of approximately 20 feet below existing grade, and conduct laboratory test(s) on representative samples for characterizing the index and engineering properties of the soils at the project site. Additional exploration by means of a Ground Penetrating Radar (GPR) survey to identify the depth of the tunnel and the presence of reinforcing steel. 2. Prepare a report presenting our findings from our field exploration, laboratory testing, and engineering recommendations for foundation types, footing depths, allowable bearing capacity, estimated settlements, excavation, engineered fill, backfill, compaction and potential construction difficulties related to excavation, backfilling and drainage, and lateral earth pressures.
