4-1.1
Geotechnical Report. A Geotechnical Report is provided as part of this RFP in
Attachment [8]. The report provides and overview of subsurface conditions, general
recommendations for design, and is furnished for informational purposes. The offeror to whom this
contract is awarded, shall perform a geotechnical investigation specific to the proposed project. The
contractor shall submit a project specific geotechnical report, certified by a professional engineer
experienced in geotechnical engineering, to include, but not limited to: description and classification
of geologic, soil, [rock,] and groundwater conditions; subsurface profiles, boring logs and location
plans; summary of laboratory and field test results; [local seismic conditions]; [local soil, rock, and
groundwater problems]; [extent of boulders;] soil resistivity, moisture, and chemistry for cathodic
protection; infiltration and permeability conditions; surface and subsurface drainage conditions;
[description of existing foundation systems]; bearing capacity of soil [and rock]; settlement type and
potential; recommendations for type and depth of foundation systems, pavement sections, slab on
grade sections; [recommendations for foundation drainage systems;] general earthwork,
compaction, dewatering, erosion and sediment control, excavation and safety requirements;
[recommendations for field tests]; [recommendations for underpinning]; [insert any site specific
requirements].
4-1.1.1
Certification. The offeror and his or her professional geotechnical engineer consultant
shall certify in writing that the design of the project has been developed consistent with the site
specific geotechnical conditions. The certification shall be stamped by the consulting professional
geotechnical engineer and shall be submitted with the First Site/Utility Design Submittal (100%) . If
revisions are made to the design submission, a new certification shall be provided with the next
design submission.
4-1.1.2
Changed Conditions. As noted in paragraph 4-1.1, the geotechnical report in the RFP
is for informational purposes and the offeror awarded the contract is responsible for conducting his
or her own project specific geotechnical investigation and report. If the contractor encounters
conditions different than provided in the RFP, the contractor shall notify the Government with the
submission of the contractor project specific geotechnical report [differences that can impact cost
such as rock or groundwater elevations; discovery of soil, rock, and groundwater problems;
discovery of contamination; changes required for foundations or pavements; changes in earthwork
requirements; etc.]. The Government shall evaluate the notification to determine if a Changed
Condition exists prior to the approval to initiate construction.
4-1.2
Soil Compaction. Soil compaction shall be achieved by equipment approved by a
professional geotechnical engineer. Material shall be moistened or aerated as necessary to provide
the moisture content that will readily facilitate obtaining the compaction specified with the equipment
used. Compact each layer to not less than the percentage of maximum density specified in Table
4-1, determined in accordance with ASTM D 1557, Method D.
