Additionally, the vendor will be required to provide casing and monuments to maintain five (5) boreholes as permanent observation wells. Optional tasks that may be required include: cone penetration testing (or an excepted alternative), technology deployment services, and technology support services.

The completion of the work will also require the rental and operation of several different types of light and heavy equipment that may not be specifically called out in the SOW but should be planned for during the technical design and pre-project planning phase of this effort. Executing the work safely and efficiently will begin with close coordination with CBP/local USBP representatives, property managers, utility locators, DigAlert, concrete/asphalt contractors, drillers, heavy equipment providers and operators, and rental equipment providers. The vendor will be responsible for all aspects of executing the SOW outlined below, including (but not limited to): scheduling deliveries and pickups of equipment, spoils management, vertical and horizontal safety barriers, traffic control, site security, site restoration, final inspection of the completed sites and providing as-built and geotechnical reports. The work will be completed at specific locations as directed by USBP personnel within the Roosevelt easement within a 5.00 mile radius of the West Port of Entry, Calexico, CA (1 E 1st St, Calexico, CA 92231).
