Date: May 22, 2020

Re: Henry E. Rohlsen Airport – Runway Shoulder and Electrical Vault

Construction

FAA AIP No.: 3-78-0002-040-2020

I. RESPONSES TO QUESTIONS

1. In consideration of Addendum 2, would VIPA please consider a bid extension till June 3rd

for the Runway 10-28 Shoulder and Electrical Vault Construction at HERA project? There is

quite a bit info to review with respect to Addendum 2, and the Memorial day holiday and

vendor pricing during the covid epidemic is adding time that would not necessarily be a

factor at alternate times. A one week extension is requested to the bid date.

Response: The Bid Date has been moved to June 10th per Addendum No. 3

2. Sheet BF-13B states that the contractor shall designate a superintendent with experience on

the Airfield Lighting Computerized Control Systems to be on site for the entire duration of

the project. The part of the project that includes the ALCMS system represents only a small

portion of the project. The shoulder, lighting and can installation is standard work and should

not need the ALCMS supervisor included. Please clarify if this supervision required under

this section will be for the installation and powering of the ALCC portion of the project only

or for the all portion of the project? Also confirm is this supervisor can be stratified by the

ALCMS systems manufacturer representative that would come down as part of the


St. Croix, VI 00820



installation, start up and training of the new system?

Response: The requirement shall be for a superintendent with experience on the Airfield

Lighting Computerized Control System to be onsite during the ALCMS portion of the

project. The ALCMS manufacturer representative does not satisfy this requirement.

3. SPECIFICATION SECTION L-127.1.1, 2 states the following: The ALCMS Contractor

shall have experience in aviation ground lighting control and be listed as an FAA approved

manufacturer in FAA AC 150/5245-568. The companies listed in this ac are qualifed

manufacturers and not installers. They will provide assistance and supervision of the

installation as well as all the startup requirements but they typically do not fill the role of

installers, can you clarify this intent?

Specification shall be revised as follows:

Section 1.1: The word “Contractor” shall be REPLACED with the word “Manufacturer”

in the third sentence TO READ: “The ALCMS Manufacturer shall have experience in

aviation ground lighting control and be listed as an FAA approved manufacturer in FAA

AC 150/5245-56B.”

Section 1.2: The wording shall be revised TO READ: “The ALCMS

Manufacturer/Contractor shall furnish, install, test and commission a complete and

functional computerized airfield lighting system, L-890BB, per FAA Advisory Circular

10/5345-56 latest edition.

4. Specification 263200 section 2.01 -the acceptable dealers as indicated in a and b of this

section do not meet the quality assurance requirements indicated in section 1.05 a and d of

this same specification due to the fact that they are not within 75 mile radius. More than

likely even those eg distributors who do meet the 75 ml radius requirement do not meet some

of the requirements of part d whereas they need to maintain "90% of all generator spare parts

available locally". Is there a more focused definition as to what spare parts means so that we

can present it to potential vendors that do meet the 75 ml radius requirement to verify that

there is an eg vendor that is acceptable? Alternatively, can you provide an eg vendor as basis

of design that is pre qualified based on the requirements of this specification?

Response: The 75-mile and 90% part requirements shall be removed from Specification

263200 Section 2.01.

5. L-127 1.17 calls out for spare parts pricing but its not evident if the spare parts are to be

included in the bid or only the pricing as a means of locking down the price over a period of

time. Can you clarify if we are to include the spare parts in the proposal?

Response: Refer to the revised Specification L-127. The section has been revised to list the

spare parts that are to be included as part of this Contract. Cost for spare parts shall be

inclusive to the pay item for the ALCMS.

6. Can the requirements of designated airfield electrical contractor as per page bf-13b in project

manual be amended to allow an electrical contractor who has succesfull y performed airfield


St. Croix, VI 00820



lighting installations in the past of comparable magnitude without imposing 5 year

limitation? This is a small territory with two airports and within the past 5 years there may

have been only two(2) projects between the two airports that would compare to this

one.technically that limits the selection of electrical contractors in the territory to two(2).

Response: Yes, See Revised Contractor Qualifications that remove the time frame for

projects of comparable magnitude.

7. Can the requirements of designated superintendent be modified to remove the time frame

requirement and to allow personnel that have succesfully carried out airfield lighting in the

past, in the territory, and of similar magnitude? For the same reason as above. Due to the

limited amount of airfield projects that are provided in the territory limits the availability of

otherwise qualified electrical contractors to two(2) as well.

Response: Yes, See Revised Contractor Qualifications that remove the time frame related

to completed airfield lighting projects.

1. On a similar job on STT we experienced close to 100 impacted days for action not related to

the contractors fault. In this bid based on the clarifications, the contractor will only be

compensated by delays on the asphalt activities. Contractors will be induced to raise their

number in order to mitigate this risk. We suggest to define an allowance to cover this delays

in order to cover the associated cost

Response: Refer to Special Provisions Section 6.0 in regard to delay claims. If the

Contractor's performance of this contract is delayed, which delay is beyond the

reasonable control and without the fault or negligence of the Contractor or its

subcontractors, or by changes ordered in the work and in either event where such

delay or change in the work impacts the CRITICAL PATH, then the Contract time

shall be extended by Change Order, as determined by the Owner.

Per Special Provision Paragraph 6.6, No additional payment will be granted outside of

the established pay items listed in the Bid set for partial or full night delays. As stated

in Addendum 2, only asphalt paving particular to the Runway will be considered for

the airline delay. It is anticipated that large portions of the taxiway and electrical vault

will be available to work on in the event of an airline delay to prevent loss of

production to avoid any critical path impacts.

8. If NOTAM is active and an air craft is to land on the runway, can the contractor be held

responsible to any citation or a violation an FAA regulations?

Response: Aircraft are not permitted to land if a NOTAM is in place without approval

from the Tower either in STX or from SJU. In the event the tower permits an

emergency landing, the contractor may be directed to leave the area by airfield

operations, the tower or by the Engineer. The contractor can be held responsible for

not following any direct orders from the Tower or Airport operations per Special

Provision Section 4.0.


St. Croix, VI 00820



9. Will there be personnel at the Control tower while works are been executed?

Response: No, the tower is closed and direct communication to pilots is the only

communication during nighttime hours. During periods of tower closures aircraft fall

under San Juan’s Tower Direction (SJU), but the contractor will not have direct

communication with San Juan.

10. Please provide doors and hardware schedule to be used in the project.

The attached Hardware schedule shall be used for the Vault Building.
