Subsurface Explorations Sample Clauses
The Subsurface Explorations clause defines the procedures and responsibilities related to investigating underground site conditions before or during a construction project. It typically outlines who is responsible for conducting soil tests, geotechnical surveys, or other subsurface investigations, and may specify how findings are to be shared with relevant parties. This clause helps ensure that all stakeholders are aware of potential underground risks, such as unstable soil or hidden obstructions, thereby reducing the likelihood of unexpected delays, cost overruns, or disputes arising from unforeseen site conditions.
Subsurface Explorations. Subsurface conditions throughout the site may vary from those depicted on logs of discrete borings, test pits, or other exploratory services. Client understands Consultant’s layout of boring and test locations is approximate and that Consultant may deviate a reasonable distance from those locations. Consultant will take reasonable precautions to reduce damage to the site when performing Services; however, Client accepts that invasive services such as drilling or sampling may damage or alter the site. Site restoration is not provided unless specifically included in the Services.

Subsurface Explorations. This task involves the following: 🢭 ▇▇▇▇ proposed exploration locations in the field and complete public utility locates 🢭 Drilling four borings through the roadway or adjacent to the roadway near each corner of the proposed bridge to depths up to 40 to 50 feet below grade, or until 15 feet of relatively competent materials are penetrated, whichever is deeper, to characterize subsurface soil and groundwater conditions at the abutments. The maximum depth of borings will be 50 feet. 🢭 Using hand auger or handheld geoprobe, conduct up to four explorations within the stream channel and two explorations on the bank of the stream These explorations will characterize the subsurface streambed material. 🢭 Obtain two surface streambed samples and conduct a sieve analysis to determine the gradation of the material. Collect one sample 200 feet upstream of the existing bridge and one 200 feet downstream. 🢭 Maintaining a log of the soils encountered in the borings and collecting soil samples for laboratory testing. 🢭 Backfilling the exploration holes in accordance with Ecology regulations and patching the surface with asphalt or gravel. 🢭 Collecting and hauling all soil spoils from the site. Assumptions ▪ If needed, the County will provide street use or right-of-way permits at no charge. ▪ Disposal of contaminated soil and decontamination of drilling equipment are not included in this scope of work. If contaminated materials are encountered, then additional costs will be incurred. ▪ Prevailing wages will apply to subcontractors (e.g. driller and traffic control). ▪ Field explorations and testing will be completed in 3 workdays, two days for drilling and one for hand augers and/or geoprobes. ▪ County survey staff will survey the borehole locations and add them to the site base map. ▪ Infiltration testing will not be necessary because stormwater quality and flow control facilities will not be required. Deliverables ▪ Preliminary copies of the boring logs.
Subsurface Explorations. The A-E shall perform the following subsurface exploration consisting of the following:
a. Drilling, logging, and sampling of hollow-stem auger borings;
b. Drilling, sampling and down-hole logging of large diameter bucket auger borings; and
c. Advancing Cone Penetration Test (CPT) soundings.
Subsurface Explorations. Where applicable, reference is made in the technical specifications for identification of those reports of explorations and tests of subsurface conditions at the site that have been utilized by CONSULTANT in preparation of the Contract Documents.
Subsurface Explorations. 13.1 Client acknowledges that subsurface conditions may vary from those observed at locations where borings, surveys, samples, or other explorations are made, and that site conditions may change with time. Data, interpretations, and recommendations by UES will be based solely on information available to UES at the time of service. UES is responsible for those data, interpretations, and recommendations, but will not be responsible for other parties’ interpretations or use of the information developed or provided by UES. 13.2 Subsurface explorations may result in unavoidable cross-contamination of certain subsurface areas, as when a probe or boring device moves through a contaminated zone and links it to an aquifer, underground stream, or other hydrous body not previously contaminated. UES is unable to eliminate totally cross-contamination risk despite use of due care. Since subsurface explorations may be an essential element of UES’s services indicated herein, Client shall, to the fullest extent permitted by law, waive any claim against UES, and indemnify, defend, and hold UES harmless from any claim or liability for injury or loss arising from cross-contamination allegedly caused by UES’s subsurface explorations. In addition, Client agrees to compensate UES for any time spent or expenses incurred by UES in defense of any such claim with compensation to be based upon UES's prevailing fee schedule and expense reimbursement policy.
Subsurface Explorations. Subsurface conditions throughout the site may vary from those depicted on logs of discrete borings, test pits, or other exploratory services. CLIENT understands NORTHPOINT’s layout of boring and test locations is approximate and that NORTHPOINT may deviate a reasonable distance from those locations. NORTHPOINT will take reasonable precautions to reduce damage to the site when performing services; however, CLIENT accepts that invasive services such as digging, drilling or sampling may damage or alter the site. Site restoration is not provided by NORTHPOINT unless specifically included in the services.
Subsurface Explorations. When the Authority is excavating test pits, the Consultant will be on-site to observe the ground conditions and locate any potential voids or fractures in the soil and rock. Following test pit observations, the Consultant will engage a drilling contractor to drill two test borings in the area of the planned by-pass piping. The drilling contractor will contact the underground utility location service and work with the Authority’s personnel so that the boring locations do not interfere with the locations of underground utilities. Drilling contractor will use a truck-mounted drill and hollow stem augers to advance the borings and will collect split spoon soil samples continuously to the top of rock following ASTM D 1586. EDI will collect rock cores from the top of rock to approximate El. 565 (about 5 feet below the elevation of ▇▇▇▇▇ Creek). During coring, we will work with drilling contractor to identify zones where the drilling rods drop or face little resistance which could indicate the presence of soil zones or voids in the rock. Drilling contractor will construct standpipe piezometers in the borings to allow us to measure the elevation of groundwater following completion of the borings. This information will provide data on the flow of groundwater from the site toward ▇▇▇▇▇ Creek. The drilling contractor’s geologist will observe the conditions in the borings and will prepare boring logs. Consultant will monitor the completion of the borings full-time to review the conditions and adjust the scope, if conditions necessitate. Consultant will also visit the site following completion of the borings to measure water levels in the piezometers and to complete a slug test in the piezometers to measure the hydraulic conductivity of the formation surrounding the well screen. The Consultant will ship selected soil samples to a geotechnical testing laboratory to test the soils for gradation and Atterberg Limits (if clayey). This will provide information regarding the potential for the soils to erode when subject to groundwater flow.
Subsurface Explorations. A. The ENGINEER shall use all existing subsurface and soil information wherever possible and shall perform additional subsurface explorations and conduct related office work as necessary for the preparation of the final design and contract drawings for the project.
1. _________days of subsurface explorations are budgeted. The ENGINEER shall prepare suitable plans and specifications so that borings and other subsurface explorations can provide information necessary for the design of the facilities to be constructed.
2. The ENGINEER will coordinate and supervise the actual performance of subsurface explorations, which may include for example solid auger ledge probes.
3. If ledge probes are used, they will be performed at designated intervals to identify any conditions (ledge, unsuitable soils, etc.) that should be noted in the final design.
