special precautions with regard to personnel safety and sample handling. The A-E will not be
allowed to begin the field effort until the Contracting Officer has approved the A-E health and
6.2.6 Geotechnical Investigation. Required for all projects which result in the imposition of
loads upon the surface of the earth. General guidance regarding the extent of field effort and
laboratory tests required for various types of projects is contained in DM-7.1. Accomplish
geotechnical work under the supervision of a professional geotechnical engineer who has
experience in "responsible charge." A professional geotechnical engineer with "responsible
charge" is defined as a registered professional civil engineer (or registered professional
geotechnical engineer with the State of California or governmental jurisdictions that specifically
register geotechnical engineers) with at least 8 years of experience in geotechnical engineering.
The geotechnical portions of the project drawings and specifications shall be reviewed by the
geotechnical engineer to ensure geotechnical issues are adequately addressed.
18.104.22.168 Inspection. For structures, the geotechnical consultant shall make at least one field
inspection during the construction of the building foundation.
The Government will furnish information regarding the existing horizontal and vertical
(horizontal control monuments and benchmarks) of the Activity. Tie into these control systems
the location and elevations of all major project structures, pavements, and other features. Where
the project location is remote from the Activity control monuments, utilize assumed local base
lines or benchmarks as approved by the Contracting Officer. The plans and specifications shall
require the construction contractor to provide permanent standard NAVY monuments in these
areas and supplemental monuments in other areas.
6.3.1 Field Surveys. Consist generally of topographic site surveys, alignment surveys, profiles
and cross-sections. Site surveys shall be conducted in sufficient detail to allow the establishment
of finish grades and show all existing structures, pavements, utility lines, obstructions, etc.,
within the limits of work. To complete the survey, the A-E shall obtain information concerning:
drainage areas; connections to existing roads; size of existing utilities; and data required to
connect new utilities to the nearest source of adequate supply.
6.3.2 Topographic Surveys. Used to site the project, provide information relating to the
development of the project site and establish property lines. Such surveys are also used to
establish metes and bounds for legal descriptions of real estate holdings and easements. The A-E
shall set a sufficient number of semi-permanent survey points which will serve as the initial
horizontal and vertical survey control for the construction of the project. (The A-E shall ensure
that these horizontal control points, benchmarks and the reference datum are clearly identified
and described on the drawings.)
6.3.3 Maps and Survey Data. All maps or other survey data furnished by the Government
are for the convenience of the A-E. The A-E shall field check and verify the data to ensure that
all survey information used in the preparation of plans and specifications are accurate and
