105 SECTION 204 MOBILIZATION
204.1 -DESCRIPTION : This work shall consist of the performance of construction preparatory operations, including the movement of personnel and equipment to the project site and for the establishment of the Contractor's offices, buildings and other facilities necessary to begin work on a substantial phase o f the contract. The bid for mobilization shall be a lump sum. When Item 204001 -*, "Mobilization", is not included as a separate bid item it is specifically understood that the cost of mobilization will be included in the unit bid price for each individua l item.
204.2 -MATERIALS : Not specified.
204.3 -CONSTRUCTION METHODS : Not Specified.
204.4 -METHOD OF MEASUREMENT : The method of measurement will be a lump sum.
204.5 -BASIS OF PAYMENT : Partial payments will be made as the work progresses in accordance with the following schedule.
whichever is less, will be released to the Contractor as the first estimate payable, not less than 15 days after the start of work at the project site. ii. 2.5% of the original contract amount or the remaining 50% of the amount bid for mobilization, whichever is less, shall be released with the estimate payable 30 days after the first estimate.
When the project is deemed substantially complete, any remaining amount bid for mobilization will be released for payment. Nothing he rein shall be construed to limit or preclude partial payments otherwise provided for by the contract. No deduction will be made, nor will any increase be made, in the lump sum mobilization item amount regardless of decreases or increases in the final tota l contract amount or for any other cause.

106 SECTION 206 BASE COURSE REINFORCEMENT GEOGRID
206.1 -DESCRIPTION : This work shall consist of furnishing, testing and installing base reinforcement geogrid elements in accordance with these specifications and in reasonable close conformity with the lines, grades and dimensions shown on the plans or established by the Engineer. Design details for base reinforcement geogrid such as geogrid type, base aggregate minimum thickness, asphalt thickn ess and associated details shall be shown on the plans.
206.2 -REFERENCE DOCUMENTS : ASTM Standards: D1388 Flexural Rigidity D4355 Practice of Sampling of Geosynthetics for Testing D4595 Test Method of Tensile Properties of Geotextiles by the Wide Width Strip Method Corps of Engineers: COE CW02215 Percent open area Geosynthetic Research Institute: GG1 Standard Test Method for Geogrid Rib Tensile Strength GG2 Standard Test Method for Geogrid Junction Strength
206.3 -GEOGRID MATERIAL : 206.3.1 -General : The Contractor shall be responsible for obtaining the geogrid reinforcement materials and associated components that meet all requirements of the Specification. Geogrid reinforcement elements shall consist of a regular network of integrally connected longitudinal and transverse polymer tensile elements with aperture geometry suf ficient to permit significant mechanical interlock with the surrounding soil, aggregate or other material.
206.3.2 -Certification of Materials and Submittals: 206.3.2.1 -Specification Compliance Certification: Prior to construction the Contractor shall submit to the Engineer the Manufacturer’s certification that the geogrid has been evaluated in full compliance with this Specification. The Contractor’s submittal package shall include; but not be limited to; the Manufacturer's written certification that all resin used to produce the geogrid is virgin and classified as polypropylene or high molecular weight polyester.
206.3.2.2-Fitness for Use: The Manufacturer of the base reinforcement geogrid shall supply written certification that the resin and add itives used in manufacture of the geogrid (including coating materials, if applicable) and that the Manufactured geogrid product has been evaluated in accordance with this specification and is durable in a soil environment. Certification shall be notarize d and signed by an officer of the manufacturing company.
