DESCRIPTION OF WORK AND PRODUCT DELIVERY A . These Specifications cover all work necessary to furnish and install , a variety of protective manhole SYSTEM ’ s . The Contractor shall deliver a finished product ( s ) including all materials , labor , equipment , and services necessary for traffic control , bypass pumping and / or diversion of sewage flows , cleaning equipment , product installation , all quality controls and samples for performance of required material tests , final inspection and warranty work , all as specified in these contract documents and at the quantities of each component contained in the Bid Proposal . B . The SYSTEM ’ s furnished shall be complete integrated and compatible systems including all materials , manufacturer ’ s recommended equipment and manufacturer ’ s installation procedures . The SYSTEM manufacturer may submit to the Owner , a minimum of 14 calendar days in advance of a bid date , all required product information to obtain pre - approval SYSTEM status . Those SYSTEM ’ s that have been preapproved will not need to be re - submitted as required in the submittal section of these specifications unless any of the system components have changed from those preapproved by the Owner . All other component products will be required to meet the submittal requirements as contained herein . C . The SYSTEM ’ s installed shall be free of all defects that will affect the design and service life and operation of the manhole . D . The SYSTEM installed shall eliminate water leakage into the manhole and prevent water or vapors to leak out of the manhole through pin - holes or other defects . If leakage occurs either in or out of the manhole the Contractor shall seal these areas to stop all leakage using a material compatible with the SYSTEM applied and as specified by the manufacturer . If leakage occurs through any SYSTEM applied to the manhole , the SYSTEM shall be repaired or removed as recommended by the manufacturer . All repair materials shall have the same estimated life expectancy than the SYSTEM installed . Final approval of the SYSTEM installation will be based on meeting the acceptance test requirements for each SYSTEM applied / installed . E . The SYSTEM ( applied to the intended structure ) shall be designed against corrosion and typical chemicals found in domestic sewage , unless otherwise specified in the detailed section of the contract documents . The manufacturer of the SYSTEM shall provide testing data that supports their SYSTEM ’ s design and service life . F . SYSTEM ’ S may be designed to rehabilitate the existing manhole against corrosion , I & I structural build - back , or a combination of the three . In certain cases the preparation , certification and submission of design calculations by a registered professional engineer is required for manhole replacement and rehabilitation technologies . All design must be supported by third party testing and documentation for the exact product that is being submitted . 1 . A manhole is specified to be structurally replaced , being able to sustain all earth , hydrostatic and dynamic loading without support by the existing structure . Certification and submission of design calculations by a registered professional engineer is required 2 . A manhole is specified to be structurally rebuilt , with build - back materials , or rehabilitated to sustain hydrostatic loading by groundwater . Certification and submission of design calculations by a registered professional engineer is required 3 . A manhole is specified to receive a corrosion protective coating sufficiently thick to totally protect the existing host structure from further corrosion , deterioration and water vapor transmission . Certification and submission of design calculations by a registered engineer may be required 4 . A manhole is specified to receive a coating to renew mortar or other deteriorated components of a manhole but has no specified longevity or corrosion resistance requirement . The manufacture ’ s third party testing will be acceptable for application suitability . 5 . A manhole is specified to receive patch repair materials for portions of the manhole . The manufacture ’ s third party testing will be acceptable for application suitability . G . All manhole steps shall be removed prior to a coating or lining application . H . Flow from existing active service connections entering the manhole shall be maintained or bypassed if the flow will affect proper SYSTEM application / installation . I . All component materials furnished , as part of this contract shall be marked with detailed product information , stored in a manner specified by the manufacturer and tested to the requirements of this contract . J . Testing shall be executed by the owner or by the contractor in the presence of the owner . Warranty inspections shall be executed by the Owner or its representative . Any defects found shall be repaired or replaced by the Contractor . K . The Contractor shall furnish all samples for product testing as required in the contract documents . The Owner shall take possession of the samples for testing and shall maintain a chain of custody , deliver the samples and pay an approved laboratory for all material and product testing performed under this contract .
