November 14, 2014 Mr. Nick DeBar, Public Works Director Page 2 of 3 Reference: 2015 Groveland Sanitary Lift Station Improvement Letter of Agreement for Engineering Services Design Phase At the point where the construction documents are ready for consideration, the project would go back to the City Council. If the Council is inclined to approve the construction documents, the project would proceed into the next phase of activity, the Bidding Phase. A separate letter regarding the details of the engineering services in the Bidding Phase would be prepared and submitted to the City at that time for consideration of authorization. The Design Phase would continue during a portion of the Bidding Phase, with the two phases overlapping for a period of time. Final activities of the Design Phase that would occur during the overlap would include final activities to obtain project permits, and any final work on the construction documents (due to feedback from the City Council, permitting agencies, etc.) prior to their distribution to potential bidders. Estimated Cost – Design Phases Engineering Services We have performed a preliminary estimate of the anticipated effort necessary to complete the work of the Design Phase for the Groveland Sanitary Lift Station Improvement Project. The estimate has been developed based on the preceding discussion of the scope of work per our Evaluation Letter Report Dated September 30, 2014, historical information from past projects, as well as our understanding of the requirements and expectations of the City of Mounds View. Per your direction, we are proceeding with Option 3 of that report which is the conversion of the lift station into a duplex submersible pump station which includes raising the structure to the surface with precast concrete manhole sections. The estimated cost of the engineering services for the Design Phase of the project is $44,000. The amount of actual engineering services needed for the Design Phase can vary based on factors beyond the control of the engineer or the City. These factors can include such things as the number and nature of questions received from potential bidders, the number of formal addenda required for the project. The cost estimate provided above has been based on a typical amount of bidder questions, and on the issuance of one formal addendum. Compensation Structure A direct hourly compensation structure is proposed for use on all engineering services for the Groveland Sanitary Lift Station Improvement Project. This is consistent with the compensation method used on past SUIP Projects. In order to use an all hourly compensation structure, it will be necessary to amend the existing Professional Services Agreement between the City and Stantec. It is suggested that as part of this letter agreements, Appendix D of the existing Professional Services Agreement be suspended, and be replaced with the following language for the Groveland Sanitary Lift Station Improvement Project which was also used in the Area H Street and Utility Improvement Project:
