Public Works Committee 5. 3. Meeting Date: 10/16/2012 By: Shane Nelson, Engineering /Public Works Title: Sunwood Drive Project - Completion of Signal System, Irrigation System and Sidewalks Background: Staff has been notified by North Pine Aggregate, the Contractor for City Project 12 -20, that some components of the contract may not be complete / operational by the completion date. The contract sets forth a completion date of November 15, 2012 for all work, with the exception of maintenance and final clean up. Due to material availability and scheduling, the mast arms for the signal system will not be available until December. The mast arms have a fairly significant lead time for production and simply will not be available before the completion date. The second item is the irrigation system. The Construction Plans contemplated the continuation of the existing irrigation supply line westerly on Sunwood Drive. However, City staff has indicated that the pressure is not adequate and has requested that a new 4" irrigation supply source be provided. A change in the scope of the water service for the irrigation system is currently being negotiated and has delayed the installation. There are also small plantings proposed at the location of the main irrigation controller that cannot be installed until the irrigation service is constructed and the controller in- place. The last item discussed is the sidewalk. Several items have impacted the installation of the sidewalks, including: the Connexus cabinet in the SE corner of Armstrong and Sunwood; the irrigation service; the existing street lights; the signal base utility conflict; and the installation /timing of the running line for the electrical outlets. Notification: North Pine Aggregate was informed of the meeting. Anoka County was also informed of the request. Observations: During the course of the construction project, several construction issues have been encountered and have impacted the Contractor's schedule. Also, as Site Plans continued to be developed for the adjacent HRA owned property, necessary revisions to this project were identified to accommodate the revised /updated development plans. Since this project overlapped with the adjacent HRA owned development, there were many moving parts and added complexity to the project. Despite some of the challenges encountered, the Contractor managed to keep the bulk of the construction on or ahead of schedule. The Contractor's goal is that all work, with the exception of the signal system, the irrigation system and associated landscaping and sidewalk will be complete by the original completion date of November 15, 2012. Extension of the completion date for items listed is reasonable due to circumstances out of the Contractor's control. Funding Source: N/A Staff Recommendation:
