Swann, PE Sopris Engineering Date: Sept. 15, 2020 Topic: 16-inch Water Main Construction Sequencing Attachment: Exhibit A.1 & A.2-WA The purpose of this memo is to summarize how the installation of the South Aspen St. – Monarch St. 16- inch water main can be accomplished under two separate scenarios. Scenario 1 considers the Lift One Lodge project commencing well in advance of the Gorsuch Haus project and what impacts this may have on the installation of the 16-inch water main. Scenario 2 assumes the Gorsuch Haus commences construction contemporaneously with the Lift One Lodge project. Because Gorsuch Haus construction requires that the operating lift be taken down, and because of the Community objective to minimize the period where the lift is decommissioned, Gorsuch Haus is not planning to start construction until Lift One Lodge commences construction. In summary, the water main can be installed under either scenario however there are some considerations that will need to be accounted for as further summarized below. Exhibit A.1 and Exhibit A.2 have been provided as an attachment for illustrative support. It should be noted that this memo is limited to identifying existing constraints associated with constructing the new water main under each scenario described above and does not provide means and methods of actual construction. Means and methods will be determined by the general contractor with direct coordination with the Engineer of Record, City Engineering and the City Water Department prior to construction. Background: The original Lift One Lodge approvals included several upgrades to the City’s utility infrastructure along S. Aspen Street to include a new water main as well as improvements to S. Aspen Street. The majority of these improvements were completed with the One Aspen project which is located along the west side of S. Aspen Street. However, approximately 500-ft of the 16-inch water main was deferred primarily to avoid future conflicts with the proposed Lift One Lodge building but also to provide an opportunity to evaluate alternative alignments as the site planning evolved with the Lift One Lodge and Gorsuch Haus projects. According to the Second Amendment to the Lift One Lodge Development Agreement (Reception #641689) the water main shall be completed by the end of the construction season of 2022 however the deadline for completion can be extended with written notice. During the Planned Development Detail Review design of the Lift One Lodge and Gorsuch Haus projects an alternative alignment for the 16-inch water main was determined. The resultant re-designed alignment considered both developments to include grading design, site improvements and various utilities associated with each project. The resultant alignment decreased the number of horizontal bends as well as provided additional separation from the Lift One Lodge building thereby improving the hydraulics of the 16- inch water main as well as future maintenance/access. The proposed design of the revised 16-inch water main alignment is depicted on the Gorsuch Haus Planned Development Detail Review Plan Set dated March 2, 2020. Scenario #1: This scenario assumes that the 16-inch water main will be installed in conjunction with the Lift One Lodge project and ahead of the Gorsuch Haus project.Several key considerations were analyzed under this 502 Main Street • Suite A3 Carbondale, CO 81623 (970) 704 -0311 Fax (970) 704 -0313 S OPRIS E NGINEERING • LLC civil consultants Pg. 2 scenario to include timing, existing grades and impacts to existing infrastructure located within Hill Street ROW and Aspen Skiing Company’s property. Each of these discussion points are outlined further below. Timing of the installation of the 16-inch water main will ultimately be dependent upon the contractor’s means, methods and schedule which will all be coordinated, reviewed, and approved by City Engineering and the City Water Department prior to construction. The current design of the Lift One Lodge building places the initial excavation benchmore than 10-ft north of the existing 12-inch water main. Separation increases to approximately 30-ft as the existing water main tracks across the proposed ski way and east through Hill Street Row. In addition, any soil nailing that might be used for shoring, associated with the excavation of the building, will need to provide a minimum of 5-ft vertical separation under all existing utilities. Based on these parameters and the existing site conditions the existing 12-inch water main could remain active while excavation of the building is underway without risking any damage to the existing line due to compromised frost protection. As vertical construction of the Lift One Lodge building progresses the need for a short retaining wall will be necessary along the southern edge of the Lodge’s south patio to retain existing and ultimate grades and therefore sequencing and timing of when this wall gets constructed will need to be considered as the proposed wall is located approximately 3-ft north of the existing 12-inch water main. Given the proximity of this site wall to the property line a cantilever type footing will be required (ie. no footer heel). Placing the footing at frost depth will place the bottom of footing approximately 12-inches above the existing 12-inch water main and therefore the site wall could be constructed while the existing 12-inch water main is active. Insulation may need to be provided if the existing 12-inch water main is to remain active through winter months as the radial bury depth at the wall will be slightly less than the required bury depth. Based on this information the existing 12-inch water main could remain active throughout the majority of construction for the Lift One Lodge project. However, if the Gorsuch Haus project has not commenced construction then there are a few existing site conditions that may complicate the installation of the 16-inch water main as outlined below. The proposed alignment of the 16-inch water main falls very close to the east side of the existing Lift 1A building. Given this close proximity the water main could not be installed along the proposed alignment without adversely impacting the existing lift building and therefore a couple of options will need to be considered: 1. The Lift One Lodge project installs 180-ft+/- of the 16-inch water main and then re-connects to the existing 12-inch water main at the east end of the Hill Street right-of-way with the remaining 300- ft+ of 16-inch water main being completed once the Gorsuch Haus improvements are underway and the existing Lift 1A building is removed and/or; 2. Lift One Lodge schedules the installation of the 16-inch water main to commence immediately following the final winter of the Lift 1A building/lift operations which would allow the existing Lift 1A building, or a portion thereof, to come down at which point the entire 16-inch water main could be installed. Another site constraint is related to an existing retaining wall located within the Hill Street right-of-way which falls immediately above the proposed 16-inch water main alignment. This existing timber crib wallretains an existing parking area at the end of S. Aspen Street and will need to be removed to install the proposed water main. After completing the installation of the water main the retaining wall could be replaced to re-establish the parking area however the alignment may need to be modified to ensure the wall is not located directly above the 16-inch water main. Additionally, the horizontal and vertical design of the 16-inch water main took into account the proposed site plan and grading design for both the Lift One Lodge and Gorsuch Haus project’s under developed conditions. With this said, as the water main tracks through Lot 2 of the Gorsuch Haus project the vertical 502 Main Street • Suite A3 Carbondale, CO 81623 (970) 704 -0311 Fax (970) 704 -0313 S OPRIS E NGINEERING • LLC civil consultants Pg. 3 design of the water main took into account the proposed grading of the ski way and re-aligned Mountain Road. Consequently, if the water main were installed ahead of the Gorsuch Haus development,and associated grading improvements for the ski way and re-aligned Mountain Road, then approximately 130-ft of the water main would be buried at a depth that exceeds the maximum allowable bury depth. This would be in addition to the portion of water main that is currently designed at depths that exceed the maximum allowable bury depth to avoid creating a high point in the line which was discussed with City Engineering and the City Water Department and determined acceptable. Lastly, the northern portion of the Gorsuch Haus’s below grade parking structure falls approximately 20-ft south of the proposed 16-inch water main and approximately 2.5-ft below the proposed 16-inch water main. This may influence the type of shoring system that will be required to excavate the northern portion of the Gorsuch Haus’s parking structure. Scenario #2: This scenario assumes that the Gorsuch Haus commences contemporaneously with the Lift One Lodge project and assumes the obligation of installing the 16-inch water main. Under this scenario the timing of the installation of the 16-inch water main will likely occur early in the construction process while other site utilities are being installed and over-lot grading is performed. Therefore, Lift 1A building will have been razed, existing timber walls removed, and existing grades will be closer to final grading conditions thereby resolving several of the constraints considered under Scenario #1. However, as noted above, consideration will be required as it relates to the shoring of the northern portion of the Gorsuch Haus building if the 16-inch water main is installed prior to excavating the parking structure. Lastly, and under either scenario, both projects will need to coordinate on the timing of any work associated with the installation of the 16-inch water main and/or decommissioning of the 12-inch existing water main to ensure work aligns and proceeds in a cooperative manner without impacting the other’s construction schedule. Exhibits A.1 & A.2 illustrate sections along the proposed 16-inch water main which reflect existing conditions as well as the proposed conditions under the Lift One Lodge and Gorsuch Haus projects. In conclusion, the 16-inch water main was designed considering both the Lift One Lodge and Gorsuch Haus projects and the Lift1A decommissioning and relocation. The alignment improves the previously approved design by eliminating several horizontal bends and increasing the separation from the proposed Lift One Lodge building and property line thereby improving the hydraulics of the 16-inch water main as well as future maintenance and access as compared to what was approved under the One Aspen Construction Drawings. In addition, the 16-inch water main can be constructed with either of the projects, however there are some existing conditions that will need to be considered as well as future shoring requirements for the Gorsuch Haus project if the 16-inch water main is installed with the Lift One Lodge project and ahead of the Gorsuch Haus project. Lastly, final design, construction sequencing, schedule, means and methods will ultimately be determined by the contractor after coordinating with the City Engineering and City Water Departments and prior to construction. 1 6 ' ' W 16''W 16''W 16''W 16''W 16''W 16''W 16''W 16''W 16''W 16''W 16''W 16''W 16''W 16''W 16''W 16''W 16''W 16''W 16''W 1 6 ' ' W 1 6 ' ' W 1 6 ' ' W 1 6 ' ' W 1 6 ' ' W ET ET ET ET ET ET ET ET ET ET ET ET ET E T E T E T E T SAN 8'' SA 8'' SA 8''SA 8''SA 8''SA 8''SA 8''SA 8''SA 8''SA 8''SA 8' ' S A 8' ' S A 8 ' ' SAN GAS GAS GAS GAS GAS GAS GAS GAS GAS GAS GAS GA S GA S GA S TC TC TC TC TC TC TC TC A I R A I R A I R A I R A I R A I R A I R A I R A I R A I R S N O W S N O W S N O W S N O W S N O W S N O W S N O W S N O W S N O W S N O W ST B K ST B K ST B K ST B K ST B K x x x XWL XWL XWL XWL XWL XWL XWL XWL XWL XWL XWL XWL XWL XWL XWL XWL XWL XWL XWL XWL XWL XWL X W L X W L X W L X W L XW L X S D XWL XW L XW L XW L XW L XWL XWL XWL S.
