There are two drawings listed that are not included in the documents available for download:

AD002 – S‐3A Service Elevator Images A‐400 – Elevator Riser Diagram Will these drawings will be issued or that they are not necessary?

List of Drawing Sheets

See 00 01 15 List of Drawings Addendum 1

TRAVELING CABLES is asking for the traveling cables to be supplied with one (1) the RG‐6 Ethernet cable for Wi‐ Fi. However, this type of cable is not designed to withstand traveling with the elevator car. Can we use additional spare shielded twisted pair, coaxial, or any other wiring in lieu of the RG‐6 Ethernet Cable?

Section 14 21 00‐ 13: 2.5, C.

Yes, per 14 21 00 – 13: 2.5,C

MICROPROCESSOR CONTROL SYSTEM is asking for VVVF Drive with regenerative capacity for hoist motor control. In lieu of a regenerative drive, will a VVVF Drive with a non‐ regenerative drive be acceptable? We will install an isolation transformer in front of the drive to filter “dirty power”.

Section 14 21 00‐ 14: 2.7, A.

No. Provide per 14 21 00 2.7 A.

Requests that the new elevators meet the requirements of the VA Seismic Design Manual H‐18‐8. Typically, these seismic requirements are reserved for locations at risk for earthquakes. Because the location of the Jesse Brown VAMC is not in an area plagued by earthquakes, would the VA consider the use of alternative, lesser seismic requirements?

Section 14 21 00 ‐ 19: 2.15, A.

No. Existing Elevators need to conform to the Seismic Requirements in the Chicago Zone.

Instructions to Offerors of the Solicitation requests that offerors submit a sustainable acquisition plan. However, elevators are a life safety trade. For this reason, it is required that we use the parts and materials specified by manufacturer guidelines. Providing sustainable materials will drastically increase costs for the VA. Would the VA consider removing this requirement from the solicitation in the interest of cost‐effective modernizations?

Page 22 Section 2.11

This requirement will be removed from the solicitation.

Evaluation Factor in the technical proposal asks for the prime SDVOSB contractor to have a State of Illinois Contractor License. Please confirm that the prime SDVOSB can utilize the licensing of our licensed subcontractors.

See Technical Evaluation Factors

Evaluation Factor in the technical proposal asks for the prime SDVOSB contractor to have 3 elevator projects $2‐ 5MM. Upon research, we find that there are minimal small business elevator contracts in the past five years. Would GLAC consider 1 elevator project at $2‐5MM, so a reduction of 2 projects in past performance and relevant experience.

No.

States that the CQC System Manager must be a graduate engineer, graduate architect, or a graduate of construction management with a minimum of 15 years construction experience on construction similar to the scope of this contract. We've seen most specs show a CQC System Manager with 5 years construction experience if they have a degree in CM, engineering or architecture and 10 years’ experience if they are not a college graduate. Will the VA still hold to 15 years’ experience which seems non‐standard for VA CQC System Manager or even the qualifications for USACE CQC Certified personnel, which is usual stated above.

Specification 01 45 00

See Section 01 45 00 Addendum 1.

PROJECT: TAYLOR ELEVATOR MODERNIZATION DATE: 05/27/2020

States that the CxA will be appointed by the VA, but the duties of the CxA are in conflict with the DIV 01 specs that state the prime is responsible for the Commissioning Plan. Please clarify if the CxA will produce the commissioning plan and that the contractor will provide the Commissioning Representatives (CxR) to produce the data for the plan.

Specification 23 08 00

The prime is responsible for the Commissioning Plan. Remove Section 23 08 00.

For the phasing requirements ‐ please confirm that we can perform the freight elevator work at the same time as (1) passenger elevator?

No, intent is to keep 4 elevators operating at one time.

Demolition note D. "patch wall opening shall match integrity of adjacent construction unless indicated otherwise." does this indicate that spec section 02 42 00 should be included? This is typical at elevator openings to have selective demolition like this work.

A001 See 02 42 19 Addendum 1.

General Note 4. between statement of work, drawings, and clarifications. Please define order of precedence.

A001

The Contractor shall seek clarification or interpretation from the VA.

General note 4 states that the prime contractor is to assume to the greatest quantity inconsistencies between drawings. How are we, on a design‐bid‐build able to quantify inconsistencies in the drawings during bid?

A001 If the Contractor, after a thorough review of all the documents, should discover inconsistencies between any parts, the Contractor shall seek clarification or interpretation from the VA.

Please confirm who is the third‐party elevator inspector for this project? Who is responsible for hiring these services, the prime contractor or the VA?

Contractor is to provide 3rd party elevator inspector for each phase of the turnover of each elevator and a final for record.

Information is irrelevant for bidding purposes.

When removing existing placards and signage panels and turning over to COR, are we expected to finish the walls to the existing finish?

Yes, any walls that are damaged by the removal of exist. placards and signage panels shall be repaired to match the existing material finish of the surrounding surface. If the surface cannot be matched locally, within a 2’‐3’ radius of the repair, than the finish shall continue to the nearest point of termination, i.e. break in material, corner of wall, protruding edges of equipment, and vertically from floor base to ceiling.

It notes to updating entire campus labels and signage to reflect new naming conventions. Please provide existing signage plan that we are to match for all elevator cards in the facility.
