STATEMENT OF WORK

GEOTECHNICAL DRILLING AND REPORT SERVICES FOR

BUILDING 523 – Rm. 101

Opportunity # 1101412

1.0 PURPOSE: To provide an investigative\exploratory report of the cause of building floor\slab settlement. Also, provide a suggested\recommended solution to remedy the affected areas and from the problem recurring.

Initial visual inspection (see pictures attached) confirms the settling of the floor\slabs.

2.0 SCOPE OF WORK: The Contractor shall furnish all plant, labor, tools, transportation, supplies, supervision, materials and incidentals necessary to perform the work described herein for the subject project. This work shall consist of providing Geotechnical Drilling Services and Geotechnical Report Services of Building 523 Chiarello Hall.

Hours of operation for the building will be Monday – Friday, 0730 – 1630.

Note: Building 523 requires escorts to enter the facility.

2.1 GENERAL: All work shall be coordinated with the Contracting Officer’s designated representative Contract Inspector (325-654-3757). All buildings shall remain occupied during all work. All work shall comply with the most current edition of the US Army Corps of Engineers Safety Manual EM 385 1.1. Also, the Contractor shall initiate and process an AF Form 103 Civil Engineer Work Request with drawings showing proposed borehole location. If necessary, the Contractor shall notify the Government of any proposed utility outage requirements 24 hours in advance. Note, the Government shall be responsible for the disconnection of building utilities, as required.

2.2 ENVIRONMENTAL PROTECTION COMPLIANCE: The Contractor shall perform all work in accordance with local, state and federal environmental laws and regulations.

This work shall include marking the site and verifying access is provided for the equipment.

Buildings 523 - Task to be performed within the interior of this building. The Contractor shall core the existing slab in multiple locations to determine the slab parameters and soil conditions beneath the slab. The Contractor will hand auger soils below the slab to the depth able to advance the hand auger or a maximum of 30” below the slab. After performing the Geotechnical Drilling Services, the Contractor shall restore the drilling site to original condition, as required.

The Contractor will analyze the soils encountered beneath the slab to determine soil parameters and the potential for soil movement. The Contractor will perform compression tests on the concrete cores retrieved and gradation on base and sub-base materials.

2.3.2 GEOTECHNICAL REPORT SERVICES: The Contractor shall also prepare a separate Geotechnical Report for each building based on the geotechnical borehole(s) and core drillings, geotechnical investigation and lab results. The report shall include site conditions, site map showing the borehole location, log of the borehole, groundwater conditions, Potential Vertical Rise estimates, results of lab tests [ie. soil moisture content, Atterberg Limits and sieve analysis], allowable bearing capacity values, foundation recommendations, provisions to mitigate the effects of expansive soils, if applicable, engineered and compacted fill material requirements, and construction testing requirements. The Contractor shall provide the Government with one printed copy plus one digital PDF copy of the resultant Geotechnical Report.
