C--IDIQ) A-E CONTRACT FOR GEOTECHNICAL AND CONSTRUCTION MATERIAL SAMPLING, TESTING, SURVEYING, ANALYSIS AND DESIGN FOR MILITARY, CIVIL, OR ENVIRONMENTAL PROJECTS WITHIN SOUTHWESTERN DIVISION (SWD) BOUNDARIES

The following work may be expected under this contract: (a) Soil and rock laboratory testing assignments may include, but are not limited to, extrusion and preparation of up to 6-inch diameter undisturbed samples, classification, mechanical grain size analysis, water content, Atterberg limits, unconfined compression tests, 'Q' and 'R-bar' triaxial compression tests, permeability tests, including flexible wall permeameter tests, and compaction tests. Materials testing assignments may include testing of aggregate, stone, bituminous, and concrete materials, including 3-point flexural strength testing of concrete. Geotechnical and materials construction quality assurance testing may also be required. Tests shall be performed in accordance with the methods presented in EM 1110-2-1906 'Laboratory Soils Testing' and with applicable ASTM and AASHTO test methods. Computation and compilation of geotechnical and materials test results will be required. Engineering reports and laboratory data shall be submitted electronically in Microsoft Word and Excel formats. Boring logs and drawings shall be furnished in a CADD format which is fully compatible with the Microstation CADD software (Version V8 or later); in addition pdf files and hard copies of all submittals shall be provided. The Contractor may be required to produce cost estimates using Corps of Engineers Computer Aided Cost Estimating System (M-CACES Gold, software provided, latest version), prepare specifications using SPECSINTACT Software, and GIS files for input to ESRI graphic systems (b) Field investigation assignments may include, but are not limited to, topographic surveying to define areas of work and/or locate borings; full service drilling including specialized drilling situations such as investigations at existing embankment dams or environmental HTRW sites and drilling in areas which are difficult to access (marsh, soft ground, or heavily forested); rock, soil and/or materials sampling, including the recovery of 6-inch diameter undisturbed soil samples by Denison barrel, Pitcher sampler, or other comparable samplers; rock pressure testing for determination of water intake; geologic mapping of existing surface conditions and/or exposed foundation conditions; hydrogeologic investigations and interpretation which may include installation of wells and/or piezometers; plugging and abandonment of monitor wells; geophysical explorations and interpretations; vibration monitoring; pile load testing; subsurface plate bearing tests; and evaluation of existing roadway and airfield pavements. (c) Geotechnical engineering work may include, but is not limited to, foundation design; roadway and airfield pavement design; HTRW containment design; borrow investigations; design and inspection of earth embankment structures; design of cut slopes and channels; seismic analysis of structures; presentation of data and designs in report form; and construction monitoring. (d) On-site laboratories may be required in support of construction activities. The laboratory may be a temporary structure provided by the Contractor or a permanent structure provided by the Government. Establishment of the laboratory may require providing utility hookups, testing equipment, supplies, office equipment, and personnel to perform the tests, as required by the individual task order. Temporary structures will be removed at the end of the work unless otherwise approved by the Contracting Officer.
