NOTE: The Township plans to prelocate existing tiles at approximately 1 to 3 locations on each farm, and GPS their locations on October 19, 2016 commencing at approx. 10:15am. Also at each prelocate trench one part of the excavation will go to design grade. Stony or unstable soil conditions are to be noted. Unstable soil conditions are not expected on this project. Photographic coverage will be made. An addendum will then be issued at a minimum of one week prior to the closing date to advise of the findings and any modifications to tile lengths and/or catchbasin design. The detail provided in the Addendum will not eliminate the need to do prelocates prior to actual tile installation,
but will reduce the extent of the prelocates. The Addendum may include copies of notes made, photos
taken and advice re tendering due to stony or unstable conditions. All proposed bidders are encouraged to attend. Bidders are advised to read the Special Provision on Drawings 14 & 15 re payment considerations for stony conditions. This Special Provision may or may not be modified by the addendum that is to be issued. The contractor is to acknowledge, where required, receipt of any addenda.
