Hazelnut Park/Glenpaul Neighborhood Street & Utility Improvements Proposal Amendment 3. Preparing the memorandum and resolution to accept bids and order the public assessment hearing for City Council consideration at the March 8th meeting. 4. Assisting the City Clerk with updates to the Assessment Roll based on amounts bid. 5. Coordinating with the City Clerk to send the final assessment notices and required publications. 6. Preparing the memorandum and resolution to conduct the assessment hearing and award the contract for City Council consideration at the April 12th meeting. We estimate these additional efforts to amount to $5,000 on these coordination efforts and are proposing the project design budget be increased to reflect this amount. Estimated Duration of Construction Services The project schedule most advantageous to the City, as confirmed at the 90% design meeting with City Staff, is identified in the final plans and specifications. Rather than allow the preliminarily estimated time/expense of a single inspector drive the project schedule, it was determined more cost effective to extend the schedule to allow a contractor to expend less overtime on its more numerous staff. While this savings may not necessarily directly observable through the unit-price based construction contracting standards, the net cost savings generated by this approach for the City will be realized through the bids. Bolton & Menk’s currently proposed construction services were established in Amendment 1 (July 2020) which was processed prior to design and development of plans/specifications. Amendment 1 was based upon an estimated construction duration of 22 weeks. The final contractual completion requirements provide an estimated 24 weeks from the assumed May 3 start date to the specified October 15 substantial completion date. Within this time, it is estimated 16 of the 24 weeks will be spent on utility work, with the remaining 8 weeks spent on surface improvements and restoration. Conversely, prior to development of detailed plans for the project, it was preliminarily estimated that 11 weeks would be spent on each of the utility and street improvement sections of the project. As a result of these considerations, which are in the City’s best interest in wholistic consideration of all project costs, Bolton & Menk proposes the following change to our scope of services: 1. Increase the estimated Construction Observation hours by 175 hours to account for: • Increase in estimated construction duration from 22 weeks to 24 weeks • Increase in estimated utility construction duration from 11 weeks to 16 weeks at an estimated 50 hours/week effort • Decrease in estimated street construction duration from 11 weeks to 8 weeks at an estimated 25 hours/week effort 2. Increase the estimated Construction Administration hours by 20 hours to account for: • Increase in estimated construction duration from 22 weeks to 24 weeks Estimated weekly hours match the same rate as the amended proposal, consistent with your direction. Summary of Proposed Changes To be Addressed via Amendment The following is a summary of proposed changes via contract amendment for the efforts outlined above: Additional Services – Design Phase $ 5,000 Expanded Coordination Services in lieu of City Staff $ 5,000 Extended Duration Construction Services Estimate $ 22,500 Total Proposed Amendment Amount $ 32,500
