Section of RFP Question Answer

Scope of Work

CLIN 0001

Do you have a specific coating you would like to see installed? Mesh can be incorporated into most coating systems.

The SOW states “The contractor shall prepare existing roof surface and apply a

Mesh Reinforced Elastomeric Roof Coating

(MERC) to the roof”. We are not specifying any particular name-brand product.

CLIN 0001

What is the substrate this is going to? The tower is a concrete roof with a bituminous roof system installed.

CLIN 0001

Is there a warranty you are looking for? We require a 2yr labor warranty for roofs.

The manufacturer warranties that come with the roof system must be provided as a part of closeout.

CLIN 0001

Does the roofing work have to take place during the weekend? Can roofing work take place while the facility is in use?

Yes the Tower roof can be worked on during weekdays while occupied. However coordination with Ground Electronics will be the deciding factor due to multiple RF antennas concerning proximity and hazards.

CLIN 0001

If roofing work can take place while the facility is in use, is access available to the roof via the inside of the tower, that can be used while the facility is in use?

Tower roof is accessible from the tower cab only. Yes the tower roof is accessible while in use but space is limited due to the angle of the stair case.

CLIN 0002

Do you have more plans for the CAB glass area showing the sizes of the frames that the glazing will be installed into?

The walls should have a smooth finish.

CLIN 0002

Per the SOW section 2, which requires

UFGS 08 88 58, 1-5/16” insulated, laminated, glazing units must be used. The existing framing will not accept this makeup, which is 1-5/16” thick. To accommodate this requirement, the framing will need to be replaced as well as an additional lite, for a total of four lites.

Per SOW section 2, 2.3.1, states “applied to new windowpanes.” Please clarify the intent. Is this to be an “applied” film?

The contractor shall supply and install new window units and install window film protection in accordance with the manufactures recommendations and procedures.

Materials

Windows shall be double glazed units.

Glass shall conform to ASTMC1036-85.

Window units shall consist of two panes of float glass separated by a 13 mm (1/2 in) air space. The outer pane shall be Type I, Class

II, Quality q3 tempered glass, slightly tinted blue/green. The inner pane shall be Type I, Class I, Quality q3, clear.

Glass Thickness

Each of the two panes shall be 6 mm (1/4

in) thick. The total window thickness shall not exceed 1 inch, with 13 mm (1/2 in) air space.

Air Space

The inner and outer panes shall be separated by a 13 mm (1/2 in) hermetically sealed space. The entrapped air shall be dehydrated by a drying agent. Dehydration shall be guaranteed for a period of ten years. Window units shall be fabricated for use at the installation’s elevation above mean sea level (AMSL). Units shall be free of any optical distortion at the time of installation.

Glazing film for hurricane protection

Install fragment retention film to provide optimum performance against low velocity impacts.

The film shall be “clear and 7mills thick”

10 Year warranty against yellowing, adhesion failure, air-bubbles etc.

CLIN 0001

CLIN #1 reference's design under 2. Scope of Work. This is the only reference to design in the RFP. Can the Gov. clarify if design is required and what the requirements are for a design.

There is no design requirement.

9 Scope of Work There is no mention of weekend work in

SOW

however it was mentioned in walk thru that would more likely be case due to the view not being disturbed. Please verify working days and the time that the work can be done on the Towers Roofing and

Windows.

The Window replacement will have to be done while the tower is not in use. Flight operations typically run from 0800-0000

M-F and 1200-2000 Sunday. The windows will have to be replaced on a Saturday.

The roof coating can happen during flight operations as long as there is limited disturbance to the Air Traffic Controllers.

10 Scope of Work

CLIN 0002

There are only 3 windows that are going to be replaced. The glass that is presently installed is 1" double pane. We will be proposing the installation of insulating laminating units; however, the units will be

1-1/8" thick as we can use a thinner glazing gasket to make the units fit within the existing framing. 1-5/16" units will not work without replacing the framing as well.

The contractor will have to ensure that the windows meet the specifications UFGS-08

88 58 “Air Traffic Control Tower Cab

Glass” and UFC 4-133-01 Air Traffic

Control and Air Operations Facilities, With

Change 2.

11 Scope of Work CLIN #1 reference's design under 2. Scope There is no design requirement.

CLIN 0001 of Work. This is the only reference to design in the RFP. Can the Gov. clarify if design is required and what the requirements are for a design.
