The Woodgate Subdivision is located along the eastern side of Woodgate Road south of Otter Road. The neighborhood was originally developed in the mid-1970s under Montrose County regulations with a sanitary sewer collection system running to a local sewage lagoon. "As public health regulations changed over time, complications with that lagoon system ultimately ended up coming up to the city's sewer system," City Engineer Scott Murphy said. The lagoon was abandoned in the 1990s as public health requirements changed. At that time, the neighborhood annexed into the city and a sewer main was extended to the neighborhood. Since the annexation, Murphy said the condition continued to diminish to the point where residents are experiencing back ups, so he said addressing the system is necessary. As part of the annexation, the city inherited operation and maintenance obligations for the sewer system. "The system was built to an unknown or non-existent standard in the county and is experiencing a lot of structural failures, root intrusions blockages and these are the sort that are warranting a full rebuild of the system," he said. As Murphy and other city employees gathered information about the condition of the system, the city worked to keep Woodgate residents informed. He said they sent letters to residences in the neighborhood and will continue to work with residents to coordinate work that impacts yards. Murphy also said many subdivision residents are aware of problems with the sewer system because those problems are also present on their private lines. In general, he said the city has had great support from residents. Residents are also encouraged to contact the city with any questions or to be placed on an email list for updates on the project. To receive notifications, email rcushenan@cityofmontrose.org. Routine updates will be posted at www.MoveMo.co. According to the city's contract documentation, the original sewer system was built primarily using thin-walled plastic irrigation pipe (PIP). The city has continually had maintenance issues with improper pipe support, collapsing pipes, separated joints, and protruding or unsealed service connections. A challenge with rebuilding the system is the location of the existing system on residential properties as the pipes run through the backyards of private lots, which requires coordination with residents for access. It also requires the contractor to use different techniques for updating the pipes, instead of digging up the existing pipe and laying in new pipe. There is also no formal piping network map. "So it doesn't lend itself to a conventional going in and digging them up and replacing the lines," Murphy said. "Hence, we're using a lot of trenchless technology to try to limit the impacts to all of the residences." The technique is called pipe-bursting: contract workers run a cutting hydraulic head and pull a new pipe inside the old pipe while bursting the old pipe out of the way. They will also install an ultraviolet cured-in-place pipe (CIPP) lining system, which acts like a resin sock that runs inside the line to cure. The resin strengthens the pipe and allows workers to reconnect service lines without residents experiencing any disruption in services. The project seeks to improve line durability, efficiency, reliability and accessibility. After putting out a call for bids on Aug. 20, the city received ones from Haynes Excavation, Skip Huston Construction and Ridgway Valley Enterprises. The council awarded the bid to the lowest bidder Haynes Excavation at $972,050.75. Throughout the rehabilitation, Haynes Excavation will complete spot repairs where failures of the pipe have occurred, insertion of new manholes and cleanout basins, and utilization of trenchless technologies to replace pipes. City Councilor Roy Anderson said he appreciated the work city staff have done to take care for residents in that neighborhood. "I think it's really admirable the amount of work you've done to put this design together and to ensure that each landowner has continued service," Anderson said. "I know that's not easy. "Everyone involved has done a great job. I think we're taking good care of our community down on that south end." The projects contain a 10% contingency in the hopes any unknown costs can be covered with those funds, rather than having to issue a change order through the council. "Although we've done a lot of investigative work to get to this point, this is a relatively high risk project because there are a lot of unknowns," Anderson said. The project is budgeted over a span of two years. The 2020 budget included $600,000 for completion of the project. Since the time the council approved the budgeted amount, city personnel discovered the system was in worse shape than anticipated, so the cost to renovate is higher. Approximately $400,000 of the project costs are anticipated to be expended in 2020 within the budgeted capital line. The remaining balance is being proposed in the sewer capital line of the 2021 budget. Work is expected to last through May 2021.

Late bids will not be accepted and it is the responsibility of the bidders to ensure that bids (including signed addenda) arrive by 2:00 PM on the date listed above. The City reserves the right to accept or reject any or all bids, to waive irregularities and/or informalities and to disregard all non-conforming, non-responsive, unbalanced or conditional bids. The City of Montrose complies with all Equal Opportunity requirements. All qualified bidders will receive consideration without regard to race, creed, color, national origin, sex, marital status, religion, ancestry, mental or physical handicap or age. The project is also bid according to the City of Montrose local preference policy in effect on the date of the bid opening and detailed in the official Municipal Code of the City of Montrose, Section 1-16-4(B). The Woodgate Subdivision is situated along the eastern side of Woodgate Road south of Otter Road. The neighborhood was originally developed in the mid-70’s under County regulations with a sanitary sewer collection system running to a local sewage lagoon. Changes in public health requirements forced this lagoon to be abandoned in the early 90’s at which time the neighborhood annexed into the City and a sewer main was extended to the neighborhood. With this annexation, the City inherited operation and maintenance obligations for the sewer collection system. The sewer system was built primarily with thin-walled plastic irrigation pipe (PIP) and was not built to any known established standard. As a result, the system has continually had maintenance issues due to root intrusion, improper pipe support, and protruding or unsealed service connections. Furthermore, the sewer system was constructed with poor access in areas between or behind multiple private residential lots. To give contractors a feel for the line locations and access conditions, a photo log of the project area is included online with the bid documents. In response to these issues, this project will perform a general overall rehabilitation of the sewer system to improve line durability, efficiency, reliability, and accessibility A. The Contractor shall make all measurements, and determine all quantities and amounts of work done under the Contract and in accordance with the bid form. At the time measurements are made for quantity determinations, the City’s Project Manager shall be present to verify such measurements. From these quantity figures, it will be the Contractor’s responsibility to prepare a monthly periodical estimate of the Work accomplished to date. This estimate shall be submitted to the City’s Project Manager on a monthly basis. The form of such monthly estimates must be approved by the City prior to use. B. No measurement and payment will be made for: 1. Work performed or materials placed outside of lines indicated in the plans or outside the scope of Work as established by the City, the plans, and the bid documents. 2.
