HomeMy WebLinkAboutASC_scope1 Lift 1a SEG Report – proposed scope refinement and additions - Scenarios 1 and 7 ASC comments 11/10/17 Scenario 1 – Gilbert Street 1. Draw and depict in plan and section, with dimensions, the pedestrian path and vertical circulation from Dean Street to the Lift elevation, e.g. the walk or landscaped plazas consisting of a series of risers and stepped platforms ascending ~50 feet vertically in ~400 feet horizontally, including a plaza adjoining the north end of the lift building at ~7990 elevation and a final set of stair risers from that plaza to the maze and lift load point. 2. Plan for and presume ticketing and skier services are located under the lift building platform, entered into from the north at elevation ~7990. Include ~1,000 – 1,500 s.f. for ticketing, restrooms, day lockers, etc. 3. Provide for ADA access from the Dean St. bus drop-off to the ticket office and to the lift load point elevation (the last rise to slope probably requires an elevator at the lift building). 4. Depict E/W cross sections through the north end of the lift building across slope and to the ground floors of existing and proposed structures east and west of the lift building, so that grades from the site walls to the adjacent buildings are shown. 5. Apart from the ski maze itself, locate and depict suitably sized ski racking and pedestrian / skier milling areas on the site plan, in part on-snow and on a plaza area on the north side of the gondola building. In short, define and depict skier circulation functions which sequentially precede skier mazing and serve end of day exiting. 2 6. Plan for and presume Ski Patrol, cat and lift crew lockers are located in the Gorsuch Haus, accessible directly from snow level, and consisting of 1,500 s.f. (300 s.f. more if shared restrooms are not available in that plan). 7. Include and depict access and staging space for emergency vehicle loading, accessible to snow, at the top of South Aspen Street at roughly 8000 ft. elevation, outside of the cul de sac fire lane. 8. Include and depict event and operations staging space, including winter and summer heavy truck unloading and material transfer to cats at the top of South Aspen Street at roughly 8000 ft. elevation, outside of the cul de sac fire lane, with connection to summer road. 9. Dimension the lift maze as shown in plan, particularly behind or north of the terminal. Depict placement of a typical access gate. Describe if or how snow maintenance can be mechanically performed by cats, including how cat access is achieved behind the gate. Otherwise, opine on the merits of using an artificial maze surface behind the terminal, such as plastic carpet from snow to the load board. 10. Depict, dimension and profile alternate lift equipment initially achieving 1,200/pph capacity, with upgrade capacity for 1,800/pph, including loading, unloading platforms and circulations patterns, specifically for: a) Telemix – quad seat and six passenger carriers, and b) Gondola – six passenger carriers, in each case considering the possibility of stand-up cabins suitably tall to permit bringing downhill racing skis into the cabins. c) Describe direction of lift rotation for each equipment type and advantages / disadvantages of the bottom and top terminal circulation patterns and requirements. d) Describe maintenance access requirements for each lift type, particularly including bull wheel or drive replacement from the side or rear of the terminal, as well as rope replacement access requirements. 3 Scenario 7 – Dean Street (including 7a - Gorsuch Haus mid-station) 1. Plan for and locate ticketing and skier services accessible from the Dean Street arrival and convenient to snow and the 7950 load elevation. Include ~1,000 – 1,500 s.f. for ticketing, restrooms, day lockers, etc. 2. Provide for pedestrian circulation and ADA access from the Dean St. bus drop-off to the ticket office and from there to snow and the lift loading elevation. 3. Apart from the ski maze itself, locate and depict suitably sized ski racking and pedestrian / skier milling areas on the site plan. 4. Plan for and presume Ski Patrol, cat and lift crew lockers are located in the Gorsuch Haus, accessible directly from snow level, and consisting of 1,500 s.f. (300 s.f. more if shared restrooms are not available in that plan). 5. Include and depict access and staging space for emergency vehicle loading, accessible to snow, at the top of South Aspen Street at roughly 8000 ft. elevation, outside of the cul de sac fire lane. 6. Include and depict event and operations staging space, including winter and summer heavy truck unloading and material transfer to cats at the top of South Aspen Street at roughly 8000 ft. elevation, outside of the cul de sac fire lane, with connection to summer road. 7. Recommend or specify snow making requirements, including seasonal volume, equipment location, capacity, hours of operation to establish, and surface storage requirements to make, manage and maintain snow access to lift and viable portal operation throughout a 140 day ski season, from late November to mid-April. 8. Estimate weekly or nightly hours of operation with snow cats and other equipment to groom, manage and maintain sufficient snow depth and surface conditions for operation throughout a 140 day ski season. 4 9. Estimate, describe and compare the distance from the western most façade of the St. Regis Hotel at Dean Street to ski yard snow and to the lift load points in Scenarios 6 and 7. 10. Generally and as specifically applied to Lift One Lodge, depict and dimension in section and plan the minimum desired set back from trail edge to building face beyond the proposed 40’ wide ski trail. 11. Depict, dimension and profile alternate lift equipment initially achieving 1,200/pph capacity, with upgrade capacity for 1,800/pph, including loading, unloading platforms and circulations patterns, specifically for: a) Telemix – quad seat and six passenger carriers, and b) Gondola – six passenger carriers, in each case considering the possibility of stand-up cabins suitably tall to permit bringing downhill racing skis into the cabins. c) Describe direction of lift rotation for each equipment type and advantages / disadvantages of the bottom and top terminal circulation patterns and requirements. d) Describe maintenance access requirements for each lift type, particularly including bull wheel or drive replacement from the side or rear of the terminal, as well as rope replacement access requirements, and including maintenance access requirements for mid-station machinery and equipment as described below. a. Locate, dimension and depict in plan, profile and section a mid-station for each lift type (e.g. quad chair, telemix, gondola) located in the vicinity of the Gorsuch Haus at approximately 8016 – 8018 elevation. i. Specifically, include the load platform length, cut and fill requirements and retaining walls required. ii. In plan and section, depict and dimension the ski trail to the east and the platform or plaza to the west adjoining the proposed Gorsuch Haus, together with any site walls required to retain slope and meet ski trail and surrounding grades. iii. In plan and section, locate, depict and dimension the vertical circulation (stairs, elevators, etc.) required to get from the South Aspen Street cul de sac at roughly 8000 feet elevation, including ADA requirements. 5 iv. Depict and describe the mid-station access, circulation requirements and patterns for loading and unloading from snow, adjacent properties and public access points, as well as impediments to such access and circulation. v. Locate, depict and dimension in plan and section the mountain access road in relationship to the mid-station. vi. Provide or prepare illustrations or depictions of the mid-station site work, retaining walls, vertical circulation and terminal equipment itself.
