GEOTECHNICAL ENGINEERING SERVICES General Geotech Engineering and Testing and its staff members have many years of experience in conducting engineering services for more than 15,000 projects. Our firm conducts over 1,200 projects a year. We conduct our services all over Texas. Field Equipment GET is equipped with five drilling rigs, including a Diedrich Drilling Rig, to perform dry or hollow stem borings. We also have two Beaver and two portable rigs. We can conduct drilling and sampling with our rigs up to 50-feet. In addition, together with our subcontractor drillers, we can drill to much deeper depths, install monitor wells, piezometers, and inclinometers. Our field crews have many years of experience in various subsoil and groundwater conditions. Our commitment to the client is to

provide dependable service, the best and most up-to-date equipment, and reliable drilling personnel. GET has the capability and experience in surveying and staking the boring locations, and providing clearance from underground utilities. In areas that are heavily wooded, we can arrange for clearing of the project site. GET is one of the few firms in Texas which is equipped with miniature rigs. These rigs are small enough that they can access hard to reach places and sites that are wooded, without significant clearing. Furthermore, since these rigs are portable, they can easily be placed on sites with wet subgrade soil conditions which create access problems.

Geotechnical Laboratory Geotech Engineering and Testing’s laboratory testing has the capabilities to perform geotechnical testing under controlled conditions in order to evaluate not only standardized test of materials, but also tests of new materials used in research and development. Our tests will be conducted in general accordance with ASTM, TxDOT and AASHTO standards. Some of the geotechnical laboratory testing capabilities are as follows:

o Moisture content o Soil suction o Unconfined Compression Test o Atterberg Limits o Permeability tests o Triaxial tests o Gradation tests o Pinhole test o Chemical tests o Consolidation tests o Torvane o Hand Pentrometer o Swell tests o Resistivity tests o California Bearing Ratio o Density tests o Proctor tests o Bar Linear Shrinkage o Organic Contents o Hydrometer tests o Specific Gravity o Compaction o Shear Strength o Soil Classification o Other specialized tests

Engineering Analysis and Report The field and laboratory data together with our engineering recommendations will be presented in an engineering report. The report will address the specific project design, construction, and quality control requirements. ENVIRONMENTAL ENGINEERING SERVICES The environmental laws require that prospective owners of properties conduct a reasonable and

appropriate inquiry into the property, its past user, and the associated environmental liabilities. Failure to recognize environmental problems at a site can result in significant financial liabilities to the purchaser or the seller. Geotech Engineering and Testing can provide Phase I, Phase II, and Phase III Environmental Studies. These studies include Hazardous Materials Initial Site Assessments, ASTM E 1527 Standard Practice for Environmental Site Assessment: Phase I Environmental Site Assessment Process, and ASTM E 1528, Standard Practice for Environmental Site Assessments: Transaction Screen Process. GET has a Corrective Action Project Manager (CAPM) on the staff to conduct Environmental Engineering Services.

GET can provide Environmental Site Assessment (ESA) studies anywhere in Texas. Our services include, but are not limited to the following:

Geotech Engineering and Testing’s Underground Tank Management Group provides consulting engineering services in the following areas: o Site reconnaissance. o Corrective action plan, operation, monitoring and

performance. o Regulatory guidance and negotiation. o Permit application preparation. o Groundwater monitoring and leak detection. o Risk assessment and remediation.

o Site reconnaissance. o Records search and review of regulatory agencies

databases. o Communications with previous owners. o Aerial photograph review of past property use. o Review of chain-of-title activity for determining past

property use. o Soil borings and monitor well installations. o Soil and groundwater sampling. o Physical and chemical testing of soil and groundwater

samples. o Permitting and remediation, recommendations. o Asbestos studies. o Geological fault studies.

Geotech Engineering and Testing combines its depth of experience with the latest in Environmental, Geotechnical, Construction Materials Engineering and computer techniques to provide information necessary for the project under consideration. Our professional staffs of engineers have intimate knowledge of the expanding technology, its uses, and its limitations. CONSTRUCTION MATERIALS ENGINEERING SERVICES

Public Agencies, Architects, Developers, and Contractors have always been concerned with the performance and quality of materials. The knowledge of how the great variety of materials used will perform is the key to the success of any project. Thus, quality assurance during construction has become increasingly important as a result of the rapid technological expansion of construction methods and materials. Quality assurance and material testing provides the evidence needed to establish confidence to all concerned that the materials and techniques used are accomplished under the standards required by the design team.

The technical staff of Geotech Engineering and Testing always strives to keep abreast of new developments and procedures utilized in quality control programs. Our engineers and field technicians provide a vital link between the owner, professional design team and the contractor. GET's abilities in construction materials testing include testing and monitoring of the following:

o Concrete testing, including but not limited to; slump, air, cylinders, beams, yield, coring, cement content, mix design verification, batch plant inspection and rebar inspection.

o Soil testing, including but not limited to; densities, proctors, plasticity indices, gradations, -200's, cement and lime stabilization, and geotechnical testing.

o Asphalt testing, including but not limited to; densities, cutback sampling, cores, theoretical specific and gravity, bulk density, gradation and extraction, mix design and stability.

o Structural steel, including but not limited to; weld inspection, A325 Bolt torque, welder qualifications, magnetic particle inspections, ultrasonic, liquid penetrant, paint thickness, holiday testing and sandblasting inspection.

GET's laboratories have been approved by Harris County, City of Houston Quality Control, City of Houston Special Testing Department, Texas Department of Transportation, Metropolitan Transit Authority and Texas Department of Criminal Justice.
