PROJECT:  Public Parking Vehicle Count System
NUMBER:  201950492-00

Current as of:  8/17/2019
 
Question Number  1:   In reference to Attachment 7, Scope of Work Section 1.2, B number 3: "3. Vehicle counts for garage roof tops and atrium surface lot spaces. Solution that require saw cuts and/or intrusion beneath the parking surface are not acceptable. Surface-mounted solutions such as inductive loops and pucks are not acceptable." Will pucks/puck-like hardware be allowed as part of the proposed solution for the rest of the garage that is covered and the only areas that pucks/puck-like hardware are not will be the uncovered/exposed areas discussed in this section above?
    Answer:   Inductive loops and pucks/puck-like hardware are not acceptable solutions for any area of the Parking Vehicle Count System project – the garage, garage roof tops, and atrium surface lot spaces.
Question Number  2:   Who provides “Area Closed” signs? If by contractor, then what is required?
    Answer:   The “Area” Closed” signs will be the responsibility of the contractor. DEN Parking can provide examples of signs used in the past by other contractors that can be referenced as a guide and DEN needs to review and approve signs before being posted. DEN Parking requires a two-week notification to customers for any closed area.
Question Number  3:   For new VMS signs, please provide: 1) specification and design drawing for base for signs; 2) DEN requirements for underground cable and protection of cable; 3) drawings showing duct banks and other obstacles in the path of underground power and comm cables; and 4) where end points for power wiring and comm cable are.
    Answer:   1) See response to question 37, we would like the signs to match those specifications. 2) requirements can be found here: http://business.flydenver.com/bizops/bizRequirements.asp 3) the utility locates are approximate and need to be field verified by the successful proposer.
Question Number  4:   Please clarify who is to provide and install the structural supports for the VMS signage to be installed by NextGen (Item D or Architectural Key Notes). There are field welds shown as well as requirements to hot dip galvanize, etc. Will the sign manufacturer provide the steel backup members and NextGen install when installing the VMS?
    Answer:   [Disregard, this question was for a similarly named project]
Question Number  5:   Please clarify who is to provide and install the structural supports for the AVI Units. There are field welds shown as well as requirements to field verify existing steel member size and coordination of plate geometry. The sections show that the AVI unit is by Others and that Attachment to Steel Tube by Others, but it is unclear whether the Steel Tube mentioned is the Existing Steel Member or the Hanger/Extending Arm.
    Answer:   [Disregard, this question was for a similarly named project]
Question Number  6:   Can DEN provide the new LPR vendor info and POC for access control?
    Answer:   The new LPR vendor will be Quercus. OSP US is the current access control provider. NextGen Parking is providing the new LPR and access control system. Please clarify if your request is for the current or new access control provider.
Question Number  7:   The project time schedule combined with prevailing wage manpower of local resources is very aggressive, this will create local workforce shortage as multiple projects are being performed at the airport. To avoid high pricing of this project to meet the contract time schedule we recommend adding 65 working days to the project schedule.
    Answer:   We believe the project time schedule is reasonable. However, we encourage proposers to provide a timeline they believe will provide the best value to the project along with reasons for the change to the schedule.
Question Number  8:   When calculating with prevailing wages how do we track professional management that are employed out of state? Also, some of our IT techs will be on site and some will remote access to set up system, calibration etc.
    Answer:   Will the professional management actively perform work on-site? If yes, you will only track the work hours that are done on-site. Same applies for the IT technicians, only the on-site work hours will need to be paid prevailing wage.
Question Number  9:   Can DEN provide drawings, CAD, PDF electric, comm, civil, structural?
    Answer:   Multiple reference documents, including drawings, were provided on the RFP project page for this project (found on http://business.flydenver.com/bizops/rfp.asp) and are listed as Attachments 1-5 and Miscellaneous 1-2. No other reference documents will be provided except by addendum if deemed necessary by DEN.
Question Number  10:   Do workers need to badge, if working in the garage/lot only?
    Answer:   At this time, all of the identified work areas are in non-secure public areas; therefore, no badging would be required to work in those areas. That said, all personnel working on behalf of the selected vendor should still meet all safety requirements.
Question Number  11:   Will DEN accept multiple proposals from the same vendor? Camera base system or sensor base?
    Answer:   No, the PVCS project is one large project and the requirements for submitting a proposal are clear on Page 4 of the RFP. Only one proposal will be accepted per company. Companies are allowed to provide multiple options/solutions in their proposals – this means that a proposal is allowed to have multiple technical solutions. Proposals which are deemed incomplete will be rejected as non-responsive.
Question Number  12:   Will DEN accept no upfront cost for this RFP scope of work with revenue sharing service agreement? If yes, can DEN provide financials?
    Answer:   DEN is open to innovative concepts. However, we will not provide financials unless the successful proposer requires them to enter into an agreement.

    Answer:   This requires field verification at each electrical room. Access will be provided to the successful proposer to verify schedules.
Question Number  23:   Companies that do business both in the US and Canada often apply for a cCSAus certification. It's a UL equivalent for the US and CSA equivalent for Canada. The criteria for cCSAus certification is more stringent than for the UL certification. Our equipment is cCSAus certified. Is our certification acceptable? Also, our sensor generates no more than 24 volts which is below UL's voltage requirements for certification. We'd like to get a clear answer to this question before incurring a lot of costs for nothing.
    Answer:   A cCSAus certification is acceptable and a UL certification for components below UL's voltage requirements for certification do not require certification for this project. Per Exhibit A - DEN PVCS Functional Specification, Paragraph 1.6.C: ""All materials and equipment will be listed, labeled or certified by a nationally recognized testing laboratory to meet Underwriters Laboratories, Inc. (UL) standards, where test standards have been established. 1. Equipment and materials which are not covered by UL Standards may be considered provided equipment and material is listed, labeled, certified or otherwise determined to meet safety requirements of a nationally recognized testing laboratory.  2. Equipment of a class for which no nationally recognized testing laboratory accepts, certifies, lists, labels, or determines to be safe, will be considered if inspected or tested in accordance with national industrial standards, such as NEMA, or ANSI.

We will install sensors at parking spaces with standard heights.
    Answer:   DEN is open to solutions that do not require saw cuts and/or intrusion beneath the parking surface. Any surface-mounted solutions such as inductive loops and pucks are not acceptable.
Question Number  47:   There are a lot of documentations required for the Proposal. It also takes a long time to calculate the BOM without AutoCAD drawings. We sincerely request you to consider a 2-week extension of the proposal due date.
    Answer:   [Response pending]
Question Number  48:   The work under the Contract is anticipated to start on or about February 2020 and has a scheduled duration of approximately five years. If contractor completes the work earlier than a scheduled duration of five years, will it be acceptable?
    Answer:   The procurement and installation must be completed within 336 calendar days from receipt of NTP. The warranty period begins after the PVCS system acceptance, this period is for 12 months. After the warranty period, the maintenance and support services period starts and is for five years following the expiration of the warrant period.
Question Number  49:   We expect it will take approximately 1.5 ~ 2 years to complete the work. Do you pay any bonus for early completion of the work if contractor completes the work in 1.5 ~ 2 years?
    Answer:   DEN will not pay any bonus for early completion of any work under this project.
Question Number  50:   We don’t see the minimum accuracy rate in your document. Is there any minimum “mandatory” detection / LPR accuracy rate?
    Answer:   Vehicle Detection (for all technology, including LPR if this is used for vehicle detection) - No minimum mandatory vehicle detection rates are set.  Contractors should submit their vehicle detection accuracy rate on the Technical Submittal form.  This rate must be achieved for the system to be accepted.  The Functional Specification section 2.3.D.3 states that there are no allowable exceptions for vehicle detection errors when computing the vehicle detection accuracy rate.  
Question Number  51:   For Ultrasonic systems, it’s not defined the LED light position for each individual stall. There are technologies in which LED is at the center of the parking stall and some others at the end of it. Is it mandatory to have the LED light at the end of the parking stall?

    Answer:   We do not have constant power at the pole for either location.
Question Number  57:   What voltage do you have at the lamp post?
    Answer:   The 5th level parking garage light poles are 277v while the Economy lots are 240v.
Question Number  58:   The RFP requires the following: “Provide new inserts and a real-time interface with existing Peña Boulevard overhead roadway VMS sign.” For the POC the RFP requires the following: “3. Peña Boulevard roadway signs: a. POC: Count the number of available spaces in each POC area and compare the total to GUI and the signs.” Does the POC require the new inserts to be installed in the roadway sign for the POC?
    Answer:   Functional Specification section 1.2.E.2.c. lists items to be included after the POC.  Item 6 states that the interface with existing roadway sign (Peña Boulevard overhead roadway VMS sign) is not part of the POC.  Disregard the Functional Specification requirement section 2.3.G.3 noted in your response related to this sign.
Question Number  59:   The RFP documents and drawings have contradictory space counts. Section II Request For Proposal Letter states there are a total 16,905 parking spaces, Attachment 7 Scope of Work Section 1.2.D Table 1 shows 16,993 spaces, and the drawings have a different count. Which quantity of spaces should prospective bidders use for their proposal? How will you handle others not bidding the actual physical counts?
    Answer:   The Price Proposal Form (PPF) uses the total number of spaces of 16,993 from Table 1 of the Functional Specification.  Actual counts may vary from Table 1 and/or from the drawings. All bidders will use the number of spaces included in the PPF to determine the quantities for for their bids.  Once the project is awarded the true number of spaces will be confirmed and the contract will be adjusted accordingly, if necessary. 
Question Number  60:   Is power available at the rooftop light poles? If so, what is the voltage and is it 24-hour continuous power?
    Answer:   The fifth level parking garage light poles are 277v, the power at this location is not continuous.
