Measurements shall be made of the total surface area covered by geogrid in square yards. Geogrid delivered and accepted will be paid for at the contract unit price inthe bidding schedule. The following shall be submitted as specified: 1 Reports -Geogrid -- Manufacturer's certified raw and roll material test reports. The Manufacturer shall certify the quality of the rolls of geosynthetic reinforcement. As a minimum, the Manufacturer shall provide quality control certificates for each batch of resin and each shift's production. These quality control certificates shall be signed by an officer of the Manufacturer, such as the production manager. Test results not meeting the requirements in Tables 1 and 2 will result in rejection of the applicable rolls. Certified test reports shall be provided seven (7) days prior to delivery to the site. The quality control certificate shall include: Roll numbers and identification -- Sampling procedures -- Results of quality control tests, including a description of test methods used. Sampling and Testing -- Manufacturer's quality control (QC) manual. Samples -- One properly identified 24 by 24 inch minimum size sample of both the biaxial and uniaxial geogrid. DELIVERY AND HANDLING -- The Manufacturer shall check the geogrid upon delivery to assure that the proper material has been received. The geogrid material shall be delivered to the site in a dry and undamaged condition. The guidelines presented in ASTM D 4873 shall be followed. The Manufacturer is responsible for the condition of the geogrid until it is delivered onsite. Once it is delivered, unloaded, inspected and accepted by the Government, the Manufacturer or its supplier is no longer liable for its condition. Inspection -- A quality assurance (QA) representative shall be present during delivery and unloading of the geogrid to inspect for damage. Labeling -- Rolls shall be labeled with the manufacturer's name, product identification, lot numbers, roll number, roll dimensions, and date manufactured. If the geogrid has a primary strength direction, it shall also be identified. Damage and Repairs -- Rolls of geogrid that are damaged during delivery, storage orhandling will be rejected. No repairs will be allowed on damaged geogrid. Handling -- Rolls of geogrid shall not be dragged, lifted by one end, or dropped to the ground. No hooks, tongs, or other sharp instruments shall be used for handling geogrids. Rolls shall be lifted by use of cables or chains in contact with the geogrid. PRODUCTS -- GEOGRID -- The Manufacturer shall be responsible for providing geogrid reinforcement materials and any associated components that meet all of the requirements of this specification. The geogrid shall be a geosynthetic manufactured for reinforcement applications, consisting of a regular network of integrally connected polymer tensile elements with apertures of sufficient size to allow strike-through (mechanical interlock) of the surrounding soil. The geogrid shall have tensile strength elements and shall be constructed of either polyethylene, polypropylene or high-tenacity polyester with the following properties, shown in Tables 1 and 2.

Instructions shall include, but is not limited to, how to prepare the foundation soil prior to placement; how to temporarily secure in-place; how to connect or splice the geogrid to provide continuity; directions on the amount of overlap required; and provide directions on how to backfill over the geogrid so that wrinkles in and/or movement of the geogrid is held to an absolute minimum. OVERSIGHT -- A qualified and experienced representative of the geogrid manufacturer or its supplier shall be on site, for a minimum of two days at the start of the installation, to assist the field personnel and the Project Engineer in the proper construction and installation techniques. Thereafter, the representative shall be available on an as needed basis, as requested by the Philadelphia District's Geotechnical Section, during the construction of the remainder of the project. MEASUREMENT AND PAYMENT -- GENERAL -- All measurements for payment shall be made by or in the presence of the Contracting Officer. The Manufacturer shall preserve all rolls in good condition until final measurement and until the records and samples have been examined and accepted. Payment will be made only for those rolls of geogrid which have been delivered undamaged and with the proper submittals listed in Section 1.3 SUBMITTALS. Payment will not be made for any roll of geogrid for which satisfactory records (and samples), as determined by the Contracting Officer, are not furnished or for materials that have been delivered damaged. BIAXIAL GEOGRID -- Measurement -- Measurement of geogrid reinforcement is on a square yard basis and shall be computed on the total area of geogrid shown on the drawing and aforementioned in this specification. This total area is to include then area of geogrids used in overlaps recommended by the Manufacturer. Payment -- Payment will be made for the area covered by the biaxial geogrid at the contract unit price for Item No. 1, "Biaxial Geogrid". UNIAXIAL GEOGIRD -- Measurement -- Measurement of geogrid reinforcement is on a square yard basis and shall be computed on the total area of geogrid mentioned in this specification. It is assumed that no overlaps are required for the installation of the uniaxial geogrid. Payment -- Payment will be made for the area covered by the uniaxial geogrid at the contract unit price for Item No. 2, "Uniaxial Geogrid". QA OVERSIGHT -- Measurement -- Measurement for QA oversight is based on the number of days that a qualified representative of the manufacturer or its supplier is onsite to assist the Contractor and Engineer in the proper construction/installation techniques. For estimation purposes, assume a total of four (4) days of QA oversight two (2) days after the geogrid has been delivered to the site, and two (2) additional days during the period of construction, both at the request of the Philadelphia District's Geotechnical Section.
