Any test results received will be passed along to the Contractor as requested, and as available. However, the City is not required to provide any test for any work to the Contractor or any other entity by any given time. The City subcontracts much of this testing and does not guarantee when the results will be received, nor the accuracy of the results.
As an example, the previous paragraph applies to the asphalt sampling as covered in Division 5 of the Specifications. Any asphalt testing done by the City will be reported to the Contractor when the results are known, but the City may take 48 hours or longer to report the results. The Contractor is responsible for knowing the Contractor=s product and equipment, and to do the work in accordance with the Contract requirements.

The high speed rotating applicator shall then be initialized and pumping of the material shall commence. As the mortar begins to be centrifugally cast evenly around the interior of the manhole, the rotating applicator head shall be raised and / or lowered at a controlled retrieval speed conducive to providing a uniform material thickness on the manhole walls.
Controlled multiple passes are then made until the specified minimum finished thickness is attained. If the procedure is interrupted for any reason, simply stop the retrieval of the applicator head until flows are recommenced.
Material thickness may be verified at any point with a depth gauge and shall be no less than a uniform 2-inch. If additional material is required at any level, the rotating applicator head shall be placed at that level and application shall recommence until that area is thickened.
Material shall be applied only when manhole is in a saturated surface dry (SSD) state, with no visible water dripping or running over the manhole walls.
The low-velocity spray nozzle and the centrifugal spin casting head may be used in conjunction to facilitate uniform application of the mortar material to irregularities in the contour of the manhole walls and bench areas.
Troweling of materials shall begin immediately following the spray application. Initial troweling shall be in an upward motion, to compress the material into voids and solidify manhole wall. A brush or broom finish may be applied if top coating is desired.
Curing will take place once the manhole cover has been replaced. It is important that the manhole cover is replaced no more than 10-20 minutes after troweling is complete to avoid moisture loss in the material due to sunlight and winds.
SEWER MANHOLE LINING 2017 Edited by SMO, City Engineer, 2016 PAGE67 Material shall not be applied during freezing weather conditions. Material shall not be placed when the ambient temperature is 37 degrees Fahrenheit and falling or when the temperature is anticipated to fall below 32 degrees Fahrenheit during 24 hours.
