University Sewer Main Commission Memorandum REPORT TO: Honorable Mayor and City Commission FROM: Bob Murray, Project Engineer Rick Hixson, City Engineer SUBJECT: Resolution 4785 authorizing Change Order No. 2 to the South University Area Sewer Main Interceptor Project. MEETING DATE: March 20, 2017 AGENDA ITEM TYPE: Consent RECOMMENDATION: Approve Resolution 4785 authorizing Change Order No. 2 to the South University Area Sewer Main Interceptor Project. BACKGROUND: Attached is a copy of resolution 4785 and change order number 2 for the above referenced project. The majority of this change involves delays and cold weather impacts associated with a conflict with an AT&T fiber optic line. The line was not located as requested during the design, but was discovered during the course of construction. The line was 16’ deep and didn’t allow the bore under 19th to be completed in the manner anticipated by the design. There were delays associated with exposing the line and discussions with AT&T to determine how to proceed. The conflict required the contractor to completely change the means and methods for the installation of the bore and the delays pushed the project into very cold weather which required additional effort on their part. A detailed description of all of the impacts and supporting information is attached to the change order. The other item was to provide an addition generator for the dewatering system to maintain accessible access from Marsh Lab to Campus. When construction started impacting the Marsh Lab area, we were made aware that there were a number of users of the building that used wheel chairs. The construction documents did not address providing an accessible route from Marsh Lab to South 19th. The Contractor’s dewatering plan included above ground pipes that would interfere with accessible access. A number of options were reviewed as to how to address the access issue and it was decided that the best method was to eliminate any dewatering pipes in this area by utilizing a separate discharge point which required a separate generator to power the pumps. UNRESOLVED ISSUES: None ALTERNATIVES: As suggested by the City Commission. FISCAL EFFECTS: Overall this change order increases the contract amount by $165,757.00 from $1,593,640.00 to $1,759,397.00. 234 Attachments: Resolution No 4785, Change Order No 2 Report compiled on: 3/7/17 235 COMMISSION RESOLUTION NO. 4785 A RESOLUTION OF THE CITY COMMISSION OF THE CITY OF BOZEMAN, MONTANA, APPROVING ALTERATION/MODIFICATION OF CONTRACT WITH DLM CONTRACTING, INC., BOZEMAN, MONTANA.
