As per you request I am attaching our proposal for the Highway 82\LightRaillPedestrian Underpass Waterline Realignment and Improvement Projects. We have grouped all five projects into one estimate, We have attempted to cover all the proposed work in our Scope of Services, however final Highway alignment changes and other factors may require changing the Scope to accommodate the required work. If you have any questions, please feel free to call me at any time. Thanks Dean D o EXHffiIT "A" SCOPE: HIGHW A Y82\LIGHT RAIL\PEDESTRlAN UNDERPASS WATERLINE REALIGNMENT AND IMPROVEMENT PROJECTS This project consists of perfomring consulting engineering work for design services for realignment of existing waterlines dealing with the installation of Highway 82 improvements, light rail train appurtenances, and pedestrian underpasses along Highway 82 from Maroon Creek Road to the Aspen Airport Business Center. The design and construction phases needed will include preparation of base mapping, line design and construction specifications, construction inspection, Record Drawings, and easements preparation for the five separate projects included in this proposal PROJECTS: 1, Maroon Creek Road Intersection: The proposed improvements may require relocation of existing 12 and lO-inch waterlines, relocation of existing valves, addition of a Pressure Reducing Vault, and other line improvements stemming from the installation of the Roundabout, light rail station and tracks, pedestrian underpass and bridge, and other work ~ 2. Truscott Place Entrance and New Maroon Creek Bridge: The existing 16 and 1 O-inch main water lines will need to be realigned to work with the new pedestrian underpass, The construction of a new Maroon Creek bridge would allow the installation of an additional 12- inch water line to feed the entire water system on the North side of the bridge, 12-inch line extension and bridge crossing. 3. Highway 82 Four Lane Improvements. Several existing water lines, valves, fire hydrants, and other water system improvements are located in the existing and proposed roadways that need to be removed, capped, or relocated. 4. Stage Road\Owl Creek Road\Buttermilk Roadway improvements and pedestrian underpass: Several water mains including a 16 and 8-inch waterlines, will need to be realigned to work with the new improvements. 5. Airport and Airport Business Center intersections and pedestrian underpass: Roadway and underpass improvements will require realignment of 18-inch and 8-inch water lines and other appurtenances. ~ r"' Base Maps Prior to the design for the line realignments and relocations, base maps will be generated using existing GIS mapping from the City of Aspen. The City's mapping does not show existing utilities accurately enough to be able to use them for design purposes. MWE reconunends that utility companies, telephone, gas, tv, sewer, water, and electrical, be contacted and have utilities be located in the field for as built conditions. The asbuilt locates will be added to the mapping provided by the City to create base maps for design purposes, This work will include reviewing existing as built drawings, contacting utilities, site visits, field locating utilities, and transferring asbuilts to the base maps for design. These maps will also need to incorporate the proposed Highway 82 improvements, pedestrian underpass locations and road designs. We have assumed that the City of Aspen and Colorado State Department Highways will be providing drawings capable of being used by Autocad R 14. Desi!!n Phase r"' The design phase will include taking the base maps compiled above and designing relocated water facilities to meet proposed highway designs and field conditions, The design will require drawings to be drafted for the line relocations, including alignment and all other work to be completed as part of the Highway 82 work. It is assumed that MWE will use existing City of Aspen pipeline details, installation, and material specifications for this project, MWE will provide the drawings at approximately I" = 20-feet horizontal, 1"= 2-foot vertical on 24" x 36" reproducible mylars to the city plus electronic files in DXF format. MWE will also provide preliminary design of the line replacements including 50% and 90% design level for review by the City of Aspen. Weare assuming that lines will be relocated within existing easements or ROW's, Construction Phase This work will includes Construction Observation and Record drawing preparation, The record drawings will require drawings to be drafted for the replacements detailing alignment and all other work completed as part of the water line extension, MWE will provide the as-built drawing on 24" X 36" reproducible mylar( s) to the City, plus the electronic file in DXF format, All survey and legal work is to be performed by the City of Aspen and should include an alignment survey, preparation of legal descriptions, plotting easements and ROW on construction plans and recording of the easement. New easements will only be required ifrealigrunent design requires the new aligrunent to be outside the existing easement or ROW. Surveying will be required to verifY both horizontal and vertical control with the existing system and the City's GIS system and new base monument layout. To insure that the installation of the water line extension will be installed according to City of Aspen and MWE drawings and specifications, MWE will provide inspection services. MWE will make daily site visits to the project to review the contractor progress, installation methods, materials, and other pertinent installation requirements. MWE will monitor tests and certifY that the water line meets design and specified quality requirements, ~ r' I"""" /""'"'..
