BIDDER'S EXAMINATION OF SITE: Before submitting a proposal, the bidder shall carefully examine the drawings, specifications, and other contract documents, and he shall visit the site of the WORK. The submission of a proposal shall be prima facie evidence that the bidder is familiar with existing site conditions and that he has a clear understanding of the requirements of the contract regarding the furnishing of materials and performance of WORK.
Where the bidder feels that additional field data are either necessary or desirable, it shall be the bidder's responsibility to make all examination and field studies necessary for his own determination of the character of materials that will be encountered in any required excavation and embankment construction operations and to fully determine all cost factors related thereto which shall be included in his bid price for the WORK.
Such additional field data required by the bidder shall be undertaken at the bidder's expense. The submittal of a bid will be accepted as prima facie evidence that in compliance herewith, the bidder has accurately and fully informed himself of all geologic and soils conditions that will influence the cost of performing the WORK and that all such factors were carefully considered by him, prior to making his bid.
COMPETENCY OF BIDDERS: In selecting the lowest responsible bidder, consideration will be given not only to the financial standing but also to the general competency of the bidder for the performance of the WORK covered by the proposal.

The Contractor shall verify pipe size and lengths prior to ordering the liner materials. The Contractor shall notify the Engineer in case that the actual size and length are different from these Contract Documents.
It is the intent of this specification to provide for the reconstruction of pipeline by the installation of a resin-impregnated flexible tube, which is tightly formed to the original pipe. The resin is cured using either hot water under hydrostatic pressure or steam pressure within the tube. The installer shall select the method of resin curing and submit to the City as a part of the submittal. The CIPP shall be continuous and tight fitting. The CIPP shall extend the full length of the original pipe and provide a structurally sound, jointless and water-tight pipe.
The Contractor shall be responsible for repairing the pipeline as necessary for the liner installation, where remote point repairs are shown to be necessary in the existing CCTV prior to any rehabilitation.
Measure and fabricate tube so when installed inside existing buried pipe, it tightly fits interior circumference and fits irregularly offset pipe joints, gradual bends of beveled pipe, cracks, pitting and other surface damage or corrosion deterioration of pipe. CIPP liner shall be of sufficient length to extend continuously between two manholes or other access structures.
In order to minimize the City’s risk, only proven products with substantial successful long-term track records will be approved. Products and Installers seeking approval must meet all the following criteria to be deemed acceptable:
1. For a Product to be considered acceptable, a minimum of 50 successful sewer system projects of similar size shall have been performed in the United States. The manufacturer shall provide the list of references to the City for approval.

Such testing results are to be used to determine the long-term, time dependent flexural modulus to be utilized in the product design. This is a performance test of the materials (Tube and Resin) and general workmanship of the installation and curing as defined within the relevant ASTM standard. A percentage of the instantaneous flexural modulus value (as measured by ASTM D790 testing) will be used in design calculations for external buckling. The percentage, or the long-term creep retention value utilized, will be verified by this testing. Retention values exceeding 50% of the short-term test results shall not be applied unless substantiated by qualified third party test data to the City’s satisfaction. The materials utilized for the contracted project shall be of a quality equal to or better than the materials used in the long-term test with respect to the initial flexural modulus used in the CIPP design.
The layers of the cured CIPP shall be uniformly bonded. It shall not be possible to separate any two layers with a probe or point of a knife blade so that the layers separate cleanly or the probe or knife blade moves freely between the layers. If the layers separate during field sample testing, new samples will be required to be obtained from the installed pipe. Any reoccurrence may cause rejection of the work.
