Question Deadline 10/01/2025 Please direct all responses and/or questions concerning this invitation to bid in writing to Rob Walker, Alaska Railroad Corporation, Supply Management, 327 W. Ship Creek Avenue, Anchorage, AK 99501, telephone number 907-265-2218, email address Walkerr@akrr.com. Questions need to be submitted one week prior to closing or they may be not accepted. This project is for slope stability improvements at ARRC Milepost 357.1. Geotechnical investigations suggest the regular slope movement is attributed to a translational slide, exacerbated by precipitation events. Mitigation measures to be completed for this project include: o Approximately 1200' drainage ditch to be built upslope of tracks, with perforated pipe and ditch liner in bottom. o Installation of 36" driven steel culvert at terminus of upslope drainage infrastructure o Installation of small diameter pipe below the 36" pipe that the upslope drainage infrastructure will drain into o Slip lining of an existing concrete culvert o Ditching on west side of tracks The improvements to drainage infrastructure in this area will facilitate moving water down slope and into the Nenana River prior to infiltration into the slide mass. The work site is accessible by an unimproved trail from the Healy Yard. Light clearing and trail improvements are expected as part of this project for Contractor access. Work shall be planned so as to minimize track outages. Train traffic is unpredictable but expected natural work windows are as follows: o Outside Passenger Season- roughly 10/1 - 4/12 dependent on weather conditions o 0600-1800 daily: expect one train/day, expect a 6-hour window daily. o 1800-0600 daily: expect one train/day, expect a 6-hour window nightly. o Typically, once per week there may be a larger track window from Sunday night or Monday morning to Wednesday afternoon; however, this is not guaranteed. o During Passenger Season - roughly 4/12 - 10/1 dependent on weather conditions o 0830-2200: several trains per day, expect a 2-hour window at some point daily. o 2200-0830: possibility of passenger delays and unscheduled freight, however, typically can expect a 6 to 8 hour window nightly. Any requests for larger windows that are not provided for by the usual train schedule must be submitted at least 30 days prior to the requested date of the outage. Contractor is to note that any work window requests affecting passenger trains will likely be denied. The above traffic schedule is provisional and may change. Train traffic must not be impeded. ARRC forces will also be utilizing tracks in the area for inspection, maintenance, and other purposes - windows are not always for the exclusive use of the contractor. Following schedule approval, ARRC will set up an internal or contracted flagger to provide track protection for the duration of the project. Contractor is to note that flaggers are not allowed to work more than 60 hours in a week, nor are they permitted to work more than six (6) days out of seven (7). Contractor requests for longer shifts or more flaggers will be evaluated on a case-by-case basis and are subject to approval by the Project Manager and the Maintenance-of-Way department at the railroad. Contractor is to bid the work as if ARRC equipment will not be available. Contractor is to provide any and all on-track equipment necessary to complete the scope of this project. All operation of on-track equipment shall be performed by individuals in accordance with 49 CFR Part 214, Subpart D- On-Track roadway maintenance machines and hi-rail vehicles. Operation of on-track equipment shall only be by a trained Roadway Maintenance machines operator. Equipment submittals and operator basis qualifications must be submitted to and approved by ARRC.
