Questions and Answers to Project Documents — Business Opportunities
PROJECT:  Life Safety Smoke Control Systems
NUMBER:  201844111-00

Current as of:  6/25/2019
 
Question Number  1:   Has this work been performed previously by a contractor and under which RFP or Purchase order issued by Denver? Is a copy of any past contracts available for review and inspection and how can that be arranged? Who is that contractor and are copies of their past inspection reports available for inspection?
    Answer:   For past contract information, reach out to the Denver Clerk and Recorder Downtown. The current contractor is Impact Engineering, Inc., Contract #201628818.
Question Number  2:   Does DEN Life Safety Representatives currently provide representatives paid for by DEN to support these tests? Is this a cost that will continue in support of this new RFP or is the contractor/supplier that is successful in this RFP responsible for 100% of all costs?
    Answer:   Two (2) Life Safety Representatives will be assigned. An engineer of the awardee in the field will instruct which piece of equipment should be tested/ run and will note any deificiencies.
Question Number  3:   We assume much of this testing time is done after hours or on an overtime basis.  Please confirm the hours of each day when testing can be performed.
    Answer:   Operational (Point to Point) testing is Tuesday / Thursday from 8:00 am to 3:30 pm. Performance testing 11:00 pm to 4:00 am. Operational issues may dictate different scheduling.
Question Number  4:   If this work is being self-performed by DEN currently, can a copy of those inspection records and baseline reports be made available for review?
    Answer:   Work is performed by an independent 3rd party. Sample reports will be provided. (See attachments 1, 2 &3 posted).
Question Number  5:   The RFP only states the buildings that have systems to be tested, but does not provide any basis of understanding in terms of the number of smoke control systems, the numbers of fans (Smoke Exhaust Fans, Stairwell & Elevator Hoist-Way Pressurization Fans, Make-up Air Fans, plus associated fire/smoke dampers and other equipment to be tested or their locations.  Please provide a detailed listing of smoke control systems by building so that cost estimates in support of the RFP can be prepared by the RFP respondents.  Note that this list also needs to include the tenant systems that may not be obvious during a simple site survey.
    Answer:   Please see Attachment A.
Question Number  6:   DEN continues to expand and evolve. There are new Smoke Control Systems that have been added within the past year and additions/modifications planned or occurring presently in multiple concourses and The Great Hall. How are changes to existing smoke control systems and the addition of new equipment (added fans, dampers and systems) to be handled as it is expected that there will be more fans, dampers, systems to be tested than currently exist today under this RFP? In other words, how will additional testing scope be added to this three year contract?
    Answer:   The airport is a dynamic environment where additions or deletions may occur within this contract. DEN Engineering wil provide the most upto date Smoke Control Matrix to the contractor upon request.
Question Number  7:   Are there any Administrative Modifications at DEN in place currently that affect smoke control systems and if so how will those documents be published for this RFP?
    Answer:   The (Administration Office Building) AOB did not change
Question Number  8:   Will a physical site survey of each Smoke Control System at DEN be scheduled?
    Answer:   We will schedule one site tour which will be announced soon (prior to the question due date).
Question Number  9:   In order to properly prepare reports, it is essential that the contractor be knowledgeable of the original Basis of Design (BOD) for each Smoke Control System in place at DEN. It is our understanding that these systems when installed are permitted separately under a deferred submittal design package with the Denver Fire Prevention Bureau and all design documents are coordinated with the mechanical contractor, fire protection contractor and fire alarm contractor. The City of Denver, DEN or the Denver Fire Department should be maintaining a database of each of these smoke control system submittals including copies of the stamped engineered drawings that would include sequences of operation and original commissioning procedures to be followed. How will these documents be distributed to proposers for review and to assist in preparing pricing? This is important as understanding the BOD for each separate system is needed in order to properly plan the tests and observe and document the results (Observation of Test results are meaningless unless you can confirm that the system is operating as originally designed and in so doing can document any impediments to the proper operation when compared to the original BOD).
    Answer:   The original Basis of Design has been changed to follow the mall code with the exception of the AOB and the Westin Hotel level 6-15. AOB/Westin are based on the high rise code.
Question Number  10:   What amount of the testing will need to be performed during off hours (i.e., at night)?
    Answer:   Performance testing is done at night.
Question Number  11:   When testing at night, what are the allowable hours that testing can be performed?
    Answer:   11:00 pm to 4:00 am
Question Number  12:   When testing at night, how many nights per week will be allowed to occur?
    Answer:   Normally two nights per week.
Question Number  13:   During the Pre-Proposal Conference, it was stated that only a third of the system needs to be tested each year. It is understood that per Denver Amendments, the Operational Test requires 100% testing each year and that the Performance Test requires one-third of the systems to be tested each year. Please confirm required amount of annual testing.
    Answer:   All locations require 100% point to point testing within 3 years. The Westin Hotel requires 100% operational and performance testing annually. Functional testing is done internally.
Question Number  14:   On page 9 of the RFP, Cost Effectiveness states that costs shall be itemized by year and for the total project. Is the Project Pricing Template to be completed for each year and for the overall project (i.e., 4 templates)?
    Answer:   A total of 4 templates should be submitted. Three templates for the annual inspection (A template for each year - Year 1, Year 2 & Year 3). The fourth template will be for the total cost.
Question Number  15:   The Project Pricing Template has a single line item for “PE Composed and Approved Final Report”. It is understood that separate Final Reports are required to be provided for each Airport Area (e.g., Terminal, Concourse A, and the Weston) identified for Operational and Performance Testing areas of the Template. Does the airport want consultants to break down the Final Report pricing down to individual airport areas? Note that this also effects the Weston overall number.
    Answer:   Final report should be one for the Westin Hotel and one for the annual airport overall.
Question Number  16:   Hours of work – I would imagine that the hours for the performance testing will be “OFF HOURS” (maybe 11 PM until 6 AM) but that the operational testing to check individual fan & damper operation (one at a time for minimal duration) could be done during normal hours since the public would typically not be aware of the testing.
    Answer:   Operational (Point to Point) testing is Tuesday / Thursday from 8:00 am to 3:30 pm. Performance testing 11:00 pm to 4:00 am. Operational issues may dictate different scheduling.
Question Number  17:   Will there be a tour of each building’s SCS (we would need documents before tour and enough time after to develop questions for the tour – see question #4 below)?
    Answer:   All systems will be viewed in the Fire Command Center during the site tour.
Question Number  18:   Are functional tests going to be required? These are required in the DBCA 2016 amendments section 909.10.5?
    Answer:   This is a semiannual test which will be conducted by DEN Aviation (internally).
Question Number  19:   We will require the following documents for bidding the SCS testing (per bldg) – a. Number of dampers (incl fan iso dampers), fans, SC zones (including retail smoke zones), stairwells & hoistways (both pressurized and non-pressurized). b. Previous SCS test reports (both operational and performance). c. SCS TrueSite displays for each building/level. d. SCS sequence of operation - both current & original (in case any changes have been made since original build). e. SCS fan schedule with CFMs.
    Answer:   Please see attachment #4
Question Number  20:   Will DEN personnel be accompanying us during all testing (no matter the hours)?
    Answer:   Yes. Two Life Safety Representatives will be assigned. An engineer of the awardee in the field will instruct which piece of equipment should be tested/ run and will note any difficiancies.
Question Number  21:   NFPA 92 Section 8.6 for Periodic Testing of smoke control systems requires verification of makeup air and exhaust air quantities. This does not appear to be a requirement of the 2016 DBCA. Is the verification of supply/exhaust airflow quantities to be included in the scope of work for this RFP?
    Answer:   Denver does not follow NFPA 92. No, verification of supply/exhaust airflow quantities will not be included.
Question Number  22:   DEN has a unique arrangement for the secondary (emergency/standby) power systems with the exception of the Westin. NFPA 92 requires smoke control system testing to be conducted while systems are operating on normal and secondary power. Is it the intent of this RFP to test all smoke control systems with secondary power systems in operation, normal power only or a percentage of tests while operating on secondary power?
    Answer:   Denver does not follow NFPA 92. All testing is done under normal power.
Question Number  23:   As is described in the 2016 Amendments to the Building and Fire Code for the City and County of Denver (online redline version available here), Sections 909.10.3 (p. 292) through 909.10.5 (p.294), describe requirements for operational, performance and functional testing. Additional testing, code adopted within the timeframe of the existing contract, may now require further testing than DEN has done so previously. Is the existing contractor and the City aware of these changes? Has the Denver Fire Department discussed any additional requirements than performed previous to 2016?
    Answer:   This contract will only include operational and performance testing. The City and current contractor are aware of these changes.
Question Number  24:   Can recent smoke control test reports be shared with interested bidders? Is there a sample report that shows results of the most recent Functional Test performed, as per DBCA 909.10.5 If not, can a device list or asset count, by terminal/location, be provided, along with date of last inspection per device?
    Answer:   Please see Attachment B
Question Number  25:   Is there any new construction within the contract period that may impact the ability for completion of the work, and/or may be added to the scope of the contract?
    Answer:   Yes there are changes. The airport is a dynamic environment where additions or deletions may occur within this contract. DEN Engineering will provide the most up to date Smoke Control Matrix to the contractor upon request.
Question Number  26:   What has been the involvement of DEN Life Safety Sections personnel in the existing Smoke Control Testing contract field tests?
    Answer:   Two (2) Life Safety Representatives will be assigned. An engineer of the awardee in the field will instruct which piece of equipment should be tested/ run and will note any difficiancies.
Question Number  27:   Can a tour be arranged for prospective bidders? If there is a tour, will badging be required for the participants? Would it be in the best of interest of DEN for the Denver Fire Department to also be present for the tour, to field any code clarifications?
    Answer:   Please see Site Tour Invitation posted.
Question Number  28:   The current RFP specifies only a Performance and Operational Test of the Smoke Control Systems. Current Denver Fire Department Amendments require a 3rd Element called Functional Testing. Each of these elements are defined in the Denver Amendments. Please clarify of the scope of this RFP is to also include the now required Functional Testing as described in the Denver Amendments.
    Answer:   All locations require 100% point to point testing within 3 years. The Westin Hotel requires 100% operational and performance testing annually. Functional testing is done internally. This is a semiannual test, which will be conducted by DEN Aviation (internally).
Question Number  29:   Sample past inspection reports that were posted to the website are form 2016 and are not complete for the entire facility. We would respectfully request copies of the test reports from 2018 Testing and that these reports include not only the AOB, Main & North Terminals and the Westin Hotel, but also the AGTS Tunnel and the three Concourses including Tenant Smoke Control Systems. Please provide or direct plan-holders on where this information can be obtained.
    Answer:   Please see Attachment B for the complete 2017 Inspection Reports.
Question Number  30:   With respect to test reports (most current and past), can it be assumed that all deficiencies and recommendation noted have been corrected, retested and that recommendations have been implemented since the report was first written?
    Answer:   Yes. All deficiencies have been found and identified and have been corrected.
Question Number  31:   With respect to the response to Question #9 provided, the question was not limited just to the type of building or general code followed (i.e. Mall or High Rise Building). What we are requesting is the original engineer’s sequence of operations for each of the separate systems including the AGTS and the Concourses and Tenants so that the information can be compared with observed performance and operational tests. Please provide.
    Answer:   The original engineer sequence has changed in some building.
Question Number  32:   Can DEN define "Operational" and "Performance" testing as they relate to the Scope of Work for this project?
    Answer:   Compliance testing = 100% of all points need to be tested annually. Performance testing = 1/3 of each building that has smoke control is to be tested so that in a 3 year cycle all areas have been tested using smoke. Westin Hotel requires 100% operational and performance testing annually. Funtional testing is done internally by DEN.
Question Number  33:   Will Funtional Testing be required (i.e. fire alarm and smoke control interface)?
    Answer:   This contract will only include operational and performance testing. The City and current contractor are aware of these changes.
Question Number  34:   Will 100% testing of any new smoke control zones be constructed and completed during the Contract period be required to e completed at the end of the period?
    Answer:   After commissioning any new smoke zone will then need to be completed in the next testing cycle.
Question Number  35:   During the site visit, it was stated that 100% operational testing (point to point) is required every year and 1/3 performance testing is required every year. However, the answer provided for Question #13, implies that 100% point to point testing is required to be complete within 3 years. Please provide clarity on percentages of operational testing and performance testing required per year.
    Answer:   Compliance testing = 100% of all points need to be tested annually. Performance testing = 1/3 of each building that has smoke control is to be tested so that in a 3 year cycle all areas have been tested using smoke. Westin Hotel requires 100% operational and performance testing annually. Functional testing is done internally by DEN.
Question Number  36:   For clarification, 1/3 of the smoke zones in the Great Hall, Levels 1-5 of the Westin, and concourses A, B, and C are to be tested annually. Of the 1/3 smoke zones tested annually, 100% of all dampers and fans will be checked for point-to-point verification. It is also our understanding that all smoke zones contained within the 1/3 sample will be tested 100%. a. What about level 6 (hotel rooms, lobby & bar) of the Westin? Shouldn’t this level of testing be for Levels 7-14, more so than 2-5? b. Please confirm if the main terminal is exempt from the testing of the fans/dampers at the top of the tents?
    Answer:   Compliance testing = 100% of all points need to be tested annually. Performance testing = 1/3 of each building that has smoke control is to be tested so that in a 3 year cycle all areas have been tested using smoke. Westin Hotel requires 100% operational and performance testing annually. Floors 6-15. The mast Top fans are not part of this contract. Functional testing is done internally by DEN.
Question Number  37:   Why is 100% of the Level 7 - Penthouse of the Westin smoke zones to be tested % annually? Best practice would be to test 100% of the SCS devices, but only 33% of the zones
    Answer:   Compliance testing = 100% of all points need to be tested annually. Performance testing = 1/3 of each building that has smoke control is to be tested so that in a 3 year cycle all areas have been tested using smoke. Westin Hotel requires 100% operational and performance testing annually. Floors 6 - 15. The mast Top fans are not part of this contract. Functional testing is done internally by DEN.
Question Number  38:   As clarification, does this scope of work include testing out all initiation devices (i.e. pull stations, smoke detectors, flow switches, etc.? This would greatly increase the scope, and is not generally part of smoke control except as required to activate smoke zones. Generally, one device per zone & alternate between smoke detectors & flow switches) throughout the airport on an annual basis, or is that work performed by DEN?
    Answer:   Initiation devices are used during the smoke control testing only to verify programming. No other device testing is required in the contract.
Question Number  39:   Will screen shots of the firefighters smoke control panel (FSCP) showing all the smoke zones and associated SCS devices be made available pre-submittal date?
    Answer:   No
Question Number  40:   How many smoke exhaust fans, hoistway pressurization fans, and stairwell pressurization fans are there throughout the airport?
    Answer:   Please see attachment #4
Question Number  41:   Are AHUs or RTUs (supply side) part of the smoke control systems? If so, need quantities also.
    Answer:   Please see attachment #4
Question Number  42:   How many smoke zones are there throughout the airport?
    Answer:   Please see attachment #4
Question Number  43:   Are the tunnels to be tested 100% each year or only 1/3 of smoke control equipment?
    Answer:   Train and bag tunnels like the buildings are 1/3 per year
Question Number  44:   Will there be airflow measurements required by DFD as part of the smoke control operational testing? If so, what measurements are required?
    Answer:   No air flow measurements are required.
