Questions and Answers to Project Documents — Business Opportunities
PROJECT:  DEN Noise Monitoring Pilot Project
NUMBER:  201845747-00

Current as of:  6/25/2019
 
Question Number  1:   Regarding this RFP, could I ask the airport to please make a copy of the IGA available?
    Answer:   The IGA Agreement is available at http://business.flydenver.com/bizops/rfp.asp
Question Number  2:   How quickly does DEN desire feedback from the monitoring system? Near-real time, hourly, daily, weekly, etc.?
    Answer:   Please refer to the IGA §5.4.2 Access to Data and §5.4.3 Annual Calculation. Real time access to system data as well as quarterly and annual reports are required.
Question Number  3:   "For noise modeling can we assume that the selected contractor(s) would have real-time (or near-real-time) access to the data streams for radar, weather tower (wind/ temperature/pressure), and recorded sound levels at existing monitoring locations for this effort? "
    Answer:   All participants of the pilot program will be individually responsible for obtaining flight track and aircraft identification data as DEN’s current access agreement does not allow sharing such data with third parties. While the method has yet to be determined, if the proposing contractor requests access to any of the other data acquired by the existing system (weather, noise, etc.), DEN will determine how to make it available, but it will likely not be in real time. All contractors will have the same access to the noise monitoring data for this project.
Question Number  4:   Is DEN considering replacing or enhancing the existing system or do you prefer a solution that utilizes the existing monitoring system hardware?
    Answer:   DEN is conducting a pilot program to review the latest capabilities and technologies to ensure compliance with the IGA. DEN has no preference as to whether a proposed solution utilizes the existing system hardware and is looking for recommendations based on state-of-the-art technologies.
Question Number  5:   The existing on-line system reports Leq only, is DEN interested in exploring additional noise metrics?
    Answer:   The IGA requires only reporting of Leq(24) values at each of the NEPS points, as well as calculation of Ldn contours. However, DEN considers the reporting of additional metrics which may provide further detail regarding noise events a desirable system feature.
Question Number  6:   Would DEN consider the possible relocation of noise monitors or were the existing sites selected as the result of noise mitigation requirements and/or existing airport flight patterns?
    Answer:   Due to their planned relation to DEN flight paths and IGA NEPS point locations, the locations of the existing noise monitor sites will need to remain unchanged.
Question Number  7:   Are any new noise-sensitive land uses being developed or planned within the DEN noise footprint that would require additional monitoring sites?
    Answer:   New noise sensitive land uses are irrelevant for this pilot program.
Question Number  8:   Is noise spectra data available from the monitoring system currently in place and will it be provided for modelling purposes?
    Answer:   DEN is uncertain as to whether the noise spectra data option can be deployed on the existing monitors and allow the monitors to continue to provide the information required for the existing system needs. If possible, then DEN would do so and provide the data.
Question Number  9:   The table on Page 10 of the RFP notes that Cover Letter must be a maximum of 1 page. Yet below the table it says “The proposer shall prepare a cover letter, not exceeding two pages in length”. Is the maximum one page or two?
    Answer:   The Cover Letter should not exceed 1 page in length.
Question Number  10:   Does the cover letter count toward the maximum total page count?
    Answer:   The cover letter does not count towards the total 40-page count.
Question Number  11:   Will the winning vendor(s) have access to DEN’s radar data feed for the duration of the study? If so, can you give general information about how often this data will be made available (e.g., daily, weekly monthly) and via what transport mechanism (e.g., FTP, HTTP).
    Answer:   No. DEN will not provide flight track and aircraft identification data for this project. All participants of the pilot program will be individually responsible for obtaining any and all data required for successful operation of their systems. Proposers have options available to obtain access to data through, at a minimum, FAA's System Wide Information Management (SWIM) program, the FAA's National Offload Program (NOP), and/or through a third-party vendor of their choice.
Question Number  12:   Will the winning vendor(s) have access to DEN’s noise monitoring data for the duration of the study? If so, can you give general information about how often this data will be made available (e.g., daily, weekly monthly) and via what transport mechanism (e.g., FTP, HTTP).
    Answer:   While the method has yet to be determined, if the proposing contractor requests access to any of the data acquired by the existing system (weather, noise, etc.), DEN will determine how to make it available, but it will likely not be in real time. All contractors will have the same access to the noise data for this project.
Question Number  13:   Is there any other data that the airport will provide during the study period, e.g., weather data? If so, please explain any pertinent details.
    Answer:   Participants of the pilot program will be required to provide a data request to DEN for which DEN will attempt to provide the data as available. While the method has yet to be determined, if the proposing contractor requests access to any of the other data acquired by the existing system (weather, noise, etc.), DEN will determine how to make it available, but it will likely not be in real time. All contractors will have the same access to the noise data for this project.
Question Number  14:   "What aircraft positioning, speed and direction information will be made available? a) What is the format of the information? b) How often is data made available? "
    Answer:   All participants of the pilot program will be individually responsible for obtaining flight track and aircraft identification data as DEN’s current access agreement does not allow sharing such data with third parties. While the method has yet to be determined, if the proposing contractor requests access to any of the other data acquired by the existing system (weather, noise, etc.), DEN will determine how to make it available, but it will likely not be in real time. All contractors will have the same access to the noise data for this project.
Question Number  15:   "What weather information will be made available? a) What is the format of the information? b) How often is data made available? "
    Answer:   While the method has yet to be determined, if the proposing contractor requests access to any of the other data acquired by the existing system (weather, noise, etc.), DEN will determine how to make it available, but it will likely not be in real time. The format of the data and access to the data will be determined and worked out with the contractor(s). All contractors will have the same access to the noise data for this project.
Question Number  16:   When modeling the NEPS points and contour area, can the terrain be considered a simple empty field or must man-made structures be included?
    Answer:   The inclusion of man-made structures as part of terrain modeling is at the discretion of proposal respondents.
Question Number  17:   Will DIA provide location and infrastructure for measurement stations that include a) Real Estate b) Security (fence) c) 110V power supply receptacle at location d) LAN access e) Concrete foundation f) Pole for microphone boom.
    Answer:   DEN will assist the contractor to secure site(s) for the setup of temporary remote hardware installations. If participants require remote sites, DEN will make a best effort to assist in the securing of the desired locations. All participants are ultimately responsible for obtaining access to the sites and installation of infrastructure required. If more than one contractor is selected, one or more sites may be coordinated among the selected contractors for comparison purposes if deemed relevant and necessary.
