Topsoil Testing

Prior to incorporation of Topsoil material into construction, the CQA CONSULTANT shall review test results from the pre-construction materials evaluation on samples from potential soil borrow sources by the CONTRACTOR’S independent CQC SOIL LABORATORY as required by the TECHNICAL SPECIFICATIONS to ascertain its acceptability as construction material. The CQA CONSULTANT will collect one random sample of the proposed borrow material and test it as required by the TECHNICAL SPECIFICATIONS to confirm its acceptability as construction material prior to providing approval for placement by the CONTRACTOR.

After the materials have been approved for use in the PROJECT, the CQA CONSULTANT will coordinate testing to be performed by the CQA SOILS LABORATORY during the course of the WORK to verify continued material compliance with the TECHNICAL SPECIFICATIONS. Any non-conformance test results obtained by the CQA SOILS LABORATORY will be reported to the OWNER, CQA CONSULTANT, and CONTRACTOR. Material not meeting PROJECT requirements will be removed at the CONTRACTORS expense if placed without prior approval by the OWNER or CQA CONSULTANT.

CONSTRUCTION QUALITY EVALUATION

Construction quality evaluation shall be performed on all soil components of the WORK. These evaluations will be performed at the frequencies indicated in the TECHNICAL SPECIFICATIONS.

Criteria used for determination of acceptability of the WORK will be as identified in the TECHNICAL SPECIFICATIONS. Construction evaluation testing includes the visual observations of the WORK; in-place density/moisture content testing; surveys of as-built conditions and elevations; thickness monitoring; and special testing. Observation of the WORK shall include, but is not limited to, the following:

Size of foreign materials and stones and other physical properties of the soil during processing, placement, and compaction.

Thickness of lifts as loosely placed and as compacted.

Action of the compaction equipment on the construction surface.

Deficiencies

If defects are discovered in the earthwork, the extent and nature shall be evaluated by the CQA CONSULTANT. If a defect is indicated by a failing test, the CQA CONSULTANT shall determine the limits of the affected area by additional tests, observations, a review of records, and other means as deemed appropriate. If the defect is related to adverse site conditions, the CQA CONSULTANT shall define the limits and nature of the defect.

Notification, Repair, and Retesting

The CQA CONSULTANT shall notify the OWNER, DESIGN ENGINEER, and CONTRACTOR after determining the nature and extent of the defect. Deficiencies shall be corrected by the CONTRACTOR to the satisfaction of the OWNER, DESIGN ENGINEER, and CQA CONSULTANT. The CQA CONSULTANT shall also verify all installation requirements as outlined in the TECHNICAL SPECIFICATIONS and this CQA Plan (i.e., material quality, thickness, and compaction) have been met and all submittals are provided. Appropriate retests shall be scheduled by the CQA CONSULTANT when the WORK deficiency is corrected.

SUBBASE

Preparation and Acceptance

The CONTRACTOR shall be responsible for preparing the Subbase upon which the GCL will be placed according to the TECHNICAL SPECIFICATIONS. Prior to acceptance, the CQA CONSULTANT shall verify the following:

A qualified land surveyor has verified all lines and grades and the CQA CONSULTANT has provided approval of the survey documents.

The supporting soil provides a firm, unyielding foundation.

The surface to be lined is relatively smooth and free of stones (greater than 1/2-inch in any dimension), protrusions, irregularities, roots, loose soil, abrupt changes in grade, or other conditions that may puncture or abrade the geomembrane.

There is no standing water or areas excessively softened by high moisture content.

All tests have been completed and meet the TECHNICAL SPECIFICATIONS and no other tests are necessary.

The INSTALLER shall certify, in writing, that the surface on which the GCL will be installed is acceptable. A “Certificate of Subbase Acceptance” shall be co-signed by the INSTALLER and the CQAR prior to commencement of installation in the area under consideration and a copy of this certificate provided to the CQA CONSULTANT. After the supporting soil has been accepted by the INSTALLER and CQAR, it shall be the INSTALLER’S responsibility to indicate to the CQA CONSULTANT any change in the supporting soil condition that may require correction. If the CQA CONSULTANT concurs with the INSTALLER, the CONTRACTOR shall ensure the supporting soil is repaired and the supporting documentation has been provided to the CQA CONSULTANT and approved.

Subbase Repair

At any time during the GCL installation, the CQA CONSULTANT shall indicate to the INSTALLER and CONTRACTOR locations which may not provide adequate support to the GCL so the areas in question can be tested and, if necessary, repaired. To that end the Subbase shall be observed by the INSTALLER and the CQAR and the decision to repair areas, if any, shall be made by the OWNER and the CQA CONSULTANT.

PROTECTIVE COVER SOIL LAYER

Placement of the Protective Cover soil material layer will only occur after the underlying geosynthetic materials installation are complete and approved by the CQA CONSULTANT in accordance with the

TECHNICAL SPECIFICATIONS.

Place Protective Cover soil material to the lines and grades shown on the CONSTRUCTION DRAWINGS. The CONTRACTOR shall place the Protective Cover soil material as shown on the CONSTRUCTION DRAWINGS to the thickness identified (measured perpendicular to the slopes).

Place Protective Cover soil material in a manner to not cause wrinkles and undue stresses to the underlying geosynthetic materials.

The CONTRACTOR shall provide and maintain a means of continuously observing the installed depth of the Protective Cover soil material on the required grid intervals in accordance with the TECHNICAL SPECIFICATIONS. If temporary markers are used, the marker shall be free standing and shall not be sharp or pointed so it cannot damage the geosynthetic materials if hit by equipment. Markers shall be removed after use and shall not be abandoned in-place after Protective Cover installation.

By survey methods, the CONTRACTOR shall verify that all grades, slopes, and elevations conform to specified requirements. Record elevations in accordance with the TECHNICAL

SPECIFICATIONS.

ANCHOR TRENCHES

The CQA CONSULTANT shall verify the anchor trenches have been constructed according to the CONSTRUCTION DRAWINGS and TECHNICAL SPECIFICATIONS. Rounded or smoothed corners shall be provided where the geomembrane enters anchor trenches to avoid sharp bends in the geosynthetic materials. No loose or excessively wet soil shall be allowed to underlie the geosynthetic materials in the anchor trenches. The anchor trenches shall be adequately drained to prevent ponding or otherwise softening of the adjacent soils while the trench is open. The anchor trenches shall be carefully backfilled and compacted by the CONTRACTOR or the INSTALLER as outlined in the TECHNICAL SPECIFICATIONS. Care shall be taken when backfilling the trenches to prevent bridging of the geosynthetic materials or damage.
