24. BRIEF DESCRIPTION OF PROJECT AND RELEVANCE TO THIS CONTRACT (Include scope, size, and cost)

From 2014 – 2017, Tierra served the City of St. Petersburg as a prime consultant for the subject contract. Under this contract, we have had the opportunity to work on several task work order assignments and with multiple City Project Managers and staff members within the City of St. Petersburg. The task work orders were varied in complexity and have included both geotechnical engineering and construction materials testing and inspection assignments. The following is a sampling of the types of projects we have completed under this contract:

Bayshore Drive Seawall Replacement: Tierra provided geotechnical services to support the design of approximately

3,000 feet of concrete seawall.

Crescent Lake Storm Drainage Improvements: Tierra provided geotechnical services to support the design which consisted of extending a 66” Reinforced Concrete Pipe parallel to an existing 42” Reinforced Concrete Pipe.

Compressed Natural Gas Fueling Station: Tierra provided geotechnical services to support the design which consisted of designing a Compressed Natural Gas Fueling Station that included a double 4x6 box culvert, paved access roads, two stormwater ponds, and concrete support slabs in portions of the site.

St. Petersburg Police Emergency Operations Center: Tierra provided materials testing and threshold inspection services during the construction of a new Police Headquarters, which included a main building with Administrative Wing, a Property & Evidence Wing, parking structure and a central energy plant on a 6.3-acre site.

For the task work order projects referenced above, Tierra performed subsurface investigations, laboratory testing in our in-house laboratory and prepared formal engineering reports summarizing our scope of services, field data, subsurface conditions encountered, engineering recommendations and materials testing results as applicable to the respective projects.
