600.3CONSTRUCTION REQUIREMENTS
The laboratory will be for the exclusive use of the Engineer. The location of the laboratory will be as directed by the Engineer and will be relocated by the Contractor, at the Contractor’s expense, as required by the Engineer. The laboratory will be required to be furnished when requested by the Engineer. On projects that a Type III lab is required, the Engineer may allow a Type I or II lab to be supplied until such a time the Engineer determines the Type III lab is required. If the Engineer allows a temporary Type I or II lab to be furnished, no additional payment for that lab will be made. The laboratory will not be removed from the project until released by the Engineer.
600.4METHOD OF MEASUREMENT
Field laboratories will be measured on a per each basis. 600 Page 407600.5 BASIS OF PAYMENT The accepted quantity of field laboratories will be paid for at the contract unit price per each. The contract unit price will be full compensation for furnishing the laboratory and specified equipment and for necessary services until the building is released by the Engineer. The field laboratory will remain the property of the Contractor. The item of Field Laboratory will not be subject to unit price negotiation regardless of any underrun or overrun of the contract quantity, nor will the provisions of Section 4.2 F, relative to reimbursement, apply in the event the entire item is eliminated. This item will not be subject to the provisions of Section 8.1. Upon placement of an acceptable field laboratory on the project, 75% of the contract unit price will be paid. Upon release by the Engineer, the remaining 25% of the contract unit price will be paid. 601 Page 408601 HAUL ROADS
601.1DESCRIPTION
This work consists of maintaining and restoring designated or approved haul roads.
601.2MATERIALS
Materials will conform to the following requirements or as approved by the local government agency and the Engineer: A.Granular Material: Granular material will be an acceptable material being used on the project. B.Asphalt Concrete Aggregate: Asphalt concrete aggregate will conform to one of the classes specified in Section 880. C.Cover Aggregate: Cover aggregate will conform to Type 3 as specified in Section 881. D.Asphalt Material: Asphalt material will be specified by the Engineer and will conform to Section 890. If any of the above materials are specified in the contract, the materials may be furnished for haul road maintenance and restoration under the same specification.
601.3CONSTRUCTION REQUIREMENTS
The related costs for the maintenance and restoration of bridges, box culverts, and pipe culverts on any haul road will be the responsibility of the Contractor. The related costs for the maintenance and restoration of roads that are not approved haul roads will be the responsibility of the Contractor. Maintenance and restoration of roads normally used for hauling material from commercial sources will be the responsibility of the Contractor. When haul roads are designated in the contract, an agreement for the use & restoration of haul roads (DOT-45) with the governmental agency or political subdivision charged with the control and maintenance of the designated roads will be included in the contract. If the Contractor elects to use a haul road not designated in the contract, or, if no haul road is designated in the contract, the Contractor will secure written approval from the Engineer with an agreement for use & restoration of Contractor’s haul road (DOT-45A), or the maintenance and repair of the haul road used by the Contractor will not be eligible for 50% payment. Approval will be given only if the road is a practical route for hauling materials. Prior to hauling materials on a designated or approved haul road; the Contractor, the governmental agency or political subdivision charged with the maintenance of the road, and the Engineer will conduct a joint inspection of the haul roads. Following this inspection, an agreement will be prepared on the haul route inspection report (DOT 45 & 45A Appendage) for the DOT-45 or DOT-45A noted above stating existing conditions and setting forth any special conditions of restoration of the haul road. The haul route inspection report must be signed by
