REQUEST FOR COUNCIL ACTION DATE: May 10, 1999 ITEM NO.: Deportment Approval: Name Gregory A. Gappa Title Director of Public Services Administrator Reviewed:Agenda Section: Engineer’s Report Item Description: Schedule Assessment Hearing for Edgewood Hills Sanitary Sewer Project The third bid opening for this project was recently held and only one bid was received, ihe iirst two times the project was bid were for a directionally boied gravity flow sewer system. These bids were higher than expected and were both rejected. This third bid included both a gravity flow system and grinder pump system option. The gravity system bid was very nigh, and the cost savings from a grinder pump system were not great enough for the residents to justify having an individual grinder pump to maintain. The bid for a gravity flow system was $252,962.00, and the bid for the grinder pump system was $161,987.80. The residents would like to have a gravity flow sewer system. The contractor suggested that if the sewer could be installed’ in the yards behind the houses the project could be completed at a lower cost. An option to install the sewer in the back yards was considered in the original feasibility study, but was rejected because of concerns about tree loss. The residents said that they are now interested in having the sewer installed in the back yard and will accept the loss of some trees. A site meeting was held with the contractor and most of the residents. A revised pipe alignment through the back yards was laid out and is acceptable to the residents. This revised alignment, located directly behind the houses, will be a combination of open cut installation and directional boring and will be shorter than the original feasibility study alignment. The contractor, GL Construction of Medina, is the same contractor that constmeted the Heritage/Shoreline project last year. This is a very good contractor and was excellent in working with the neighborhood residents. We are very satisfied with the quality of their work. GL Construction was also the only bidder the last two times that Edgewood Hills was bid. The contract specifications reference a MNDOT provision for "value engineering" for this project. This concept allows the contractor to propose alternate methods for project construction that are more cost effective. The revised sewer alignment developed by the contractor and neighborhood residents is a better and more cost-effective solution for this project. Also, the residents are comfortable with the contractor and are supportive of the revised alignment. We have obtained a value engineering proposal from GL Construction for the revised alignment. We have compared this proposal to other bid prices we have received and believe the proposal is a fair and reasonable price for the project. The construction cost for the revised gravity flow system was $158,620. This project has also been discussed with the City Attorney and is acceptable to him.
