McClure and Sons Inc. 4/28/2018 Change Order 1

Project: Three Lakes Valve Bypass Change Order No.1 Change Order Effective Date: March 20, 2018 vault, and to account for costs to construct a concrete lid. The concrete slab lid will provide a safer and more secure cover. 3. Reinforced Concrete Pad for Generator. The structural engineer determined that placing the backup generator on top of the vault slab would add unnecessary weight to the structure. This new item is being added to account for materials costs to construct concrete generator pad in location adjacent to vault. 4. Add Air/Vacuum Valve Schedule 80 piping, restrained to vault with anchor bolts. This new item is being added to vent the Air/Vacuum valve to the outside of the vault, rather than discharging into the vault, and to account for costs for the added work. 5. Eliminate Concrete Encasement for 24-Inch Access Manway, Detail Drawing D4: The approved drawings called for a reinforced concrete encasement for each 24-inch access manway, which included concrete and rebar. The City of Everett maintenance and operations groups said the concrete was not needed or desired and thus were eliminated, resulting in a credit to the City of Everett. New Item# 102 —Additional Restrained Welds. The plans called for welding three exterior pipe joints for the existing 51-Inch Water Transmission Line upstream and downstream of the new 51"x36" wye segments. The welding of the pipe joints is to provide enough thrust control so as to avoid a joint failure when the bypass piping is put into use. While excavating to prepare for the wye connections, three additional pipe joints were found that needed to be welded to provide the necessary thrust control. This item is being added to account for costs to weld three additional pipe joints. New Item # 103—Additional Labor and Equipment Costs. Because this project is a Lump Sum project, it did not include a force account bid item to pay for additional costs for miscellaneous changes to the Contract. This item is being added to account for additional labor and equipment costs due to added work that was not part of the original Contract as described below. 1. Excavation costs for additional joint welding. 2. Place pipe bedding, backfill, and compact trench excavation for additional joint welding. 3. Move jobsite trailer and storage Conex for access to pipe for additional joint welding. 4. Core 8-Inch opening into concrete vault for 8-inch Air/Vacuum Valve. 5. Construct reinforced concrete pad for backup power generator. New Item # 104—Early Finish Incentive Bonus. The Contract included an early finish incentive bonus of$7,500.00 per hour, up to a maximum of two hours (Contract Section 00 60 13-1.2D)to encourage the Contractor to expedite work during the water shutdown in order to ensure water customers had water as soon as possible. The Contractor was allowed 36 hours to complete the shutdown work and completed it within 24 hours, thus earning the two hour maximum bonus. This item is being added to account for the $15,000.00 bonus the Contractor earned. Contract Time: There are no calendar days added to this Contract. Page 4 of 4
