Additional discussion was held on the manhole modification at Beam Avenue. Earl said he has explained the District's concerns to Park Construction and asked them to finish this modification as soon as possible so that water can travel this pipe section to reduce buoyancy. They have until October 12 to complete this modification according to the terms of the contract. In order to respond to the needs of both the contractor and the District, Earl had suggested that they at least complete the bottom half of the modification so that they would have an overflow for extreme events. It appears that Park does not want to move up the schedule on the manhole modification. If the Board is uncomfortable with waiting, they could direct the contractor to do it earlier for an additional cost. The frost is out of the ground, and as of yesterday, Earl saw no evidence that this pipe section is floating. Earl presented Change Order #1 in the amount of $16,250 for approval and signature. The grading was modified in a low spot in the corner of the golf course, and drain the and an outlet were added. Roger Lake asked if there was any basis to justify cost-sharing with the golf course, to which Cliff Aichinger indicated that the golf course doesn't achieve any new benefit. The change order work. is replacing previous conditions. Motion: Paul Ellefson moved, Bob Johnson seconded, to approve Change Order #1 for the Kohlman Basin Project. The motion was carried. Beltline Sewer Hvdraulics/Beltline Sewer Repair Bob Johnson asked how the repairs are documented. Earl stated that atwo-step process is followed with each project: actual pipe inspection takes place first, and then the repairs are documented. Barr updates their plan sets to identify the pipe locations, and drawings are added to each station where repairs hove been made. As long as Barr remains the District's technical consultant, the permanent library of project records will be maintained by them as active files. If that arrangement were Pver to change, the transfer of a massive amount of permanent records would be addresses. Earl reported that the contractor is already working past his contract completion date of March 1. The contractor is confident that he can complete the repairs scheduled under the current contract by April I7. Earl does not object to giving him one more try. Roger Lake asked if there is any significant risk of damage or failure during the summer if all repairs are not completed. Earl reported that overall, the pipe is in substantially better condition than it was last fall, which is consistent with long-term goals outlined in our feasibility study to prevent pipe failure. Isolated blow-outs, however, will always be a risk to the Distract. . There are still at least two more winters of work left to do, and the Beaver Lake and Phalen branch will be next winter's focus. The bid package for next winter heeds to L-e brought to the Board at the June meeting in order to start in November. CIP and Water~vay Maintenance Brad Lindaman explained that Dryden Excavating has removed. and disposed of deadfalls and brush carried by Fish Creek to the structure on the east side of I-494. When asked if there were alternatives to disposal of this material, he stated it is too saturated to be piled and burned. Also, Cliff stated that the city acid county presently have an overabundance of wood chips. Brad Lindaman has a few more changes to make before the bid documents are finalized for the Mcknight Basin sediment removal. Brad will focus the bid advertisement on local contractors by using the District's legal newspapers. Brad discussed the engineers reassessment of needed repairs in the concrete flume along Lower Afton Road. Motion: Roger Lake moved, Paul Ellefson seconded, to approve the engineer's revised estimate for repair of the concrete flume. Page 2 April 1, 1998 RWMWD Minutes
