RE: Scope for Geotechnical Services and Lead Based Paint and Asbestos Surveys Sarasota–Bradenton International Airport Ground Transportation Center Project Sarasota County, Florida Tierra Project No: 6511-21-068
Mr. Baldocchi:
Tierra, Inc. appreciates the opportunity to present the scope herein. This scope is based on information provided and our understanding of the project.
Project Description
The project consists of improvements to the ground transportation center at Sarasota-Bradenton International Airport (SRQ). This proposed scope has been developed to provide subsurface sampling, testing, geotechnical engineering, and laboratory services to support the design. In addition, scopes covering lead based paint and asbestos surveys are included herein.
Based on a review of aerial photography and our previous experience with the airport, we anticipate the project area will be accessible to our drilling equipment following coordination and scheduling. Tierra will perform borings where feasible and perform minor Maintenance of Traffic (MOT) services, if required.
Geotechnical - Scope of Services
Based on our understanding of the project, the following scope of services is anticipated:
Mobilize personnel and equipment to the site. Coordinate utility clearances through Sunshine One Call and the airport.
Perform a subsurface exploration program consisting of the following:
Lounge Building – Perform one (1) Standard Penetration Test (SPT) boring within the proposed Lounge building footprint to a depth of 25 feet below grade.
Canopy Structures – Perform SPT borings within selected canopy foundation locations. Tierra anticipates performing borings on approximately 100-foot intervals along the canopy footprint to depths of 15 feet below grade.
Pavement Design – Tierra will perform pavement cores in the existing pavement to determine the current pavement sections (thicknesses and type).
Measure and record groundwater levels following completion of each boring.
Grout and/or backfill all borings to the surface and thoroughly clean work areas of loose debris, soils, mud, etc. Following pavement cores, Tierra will place asphalt patch from the bottom of the existing base course to the pavement surface.
