This is a Design-Build (DB) construction to replace all exterior windows of Building 6 at NSAP with energy efficient windows. The window replacements will be completed in-kind where the new material will duplicate the material, dimensions, and detailing of the existing non-significant replacement windows. The original window openings will retain their original size and shape. The proposed action is required to increase energy efficiency of the building. The general scope of work and requirements for this task order includes - but is not limited
to:
1. Provide a life cycle cost analysis (LCCA) to select windows and glazing with the
best possible performance for:
a. U-factor
b. Solar Heat Gain Coefficient (SHGC)
c. Daylighting
d. Visible Transmittance
2. Provide heavy-duty commercial quality aluminum windows conforming to
AAMA/WDMA/CSA 101; must have anodized aluminum finish with color to match
previous existing windows or meet the applicable installation exterior architectural
guidelines.
3. Windows must match size (height x width) of existing windows being replaced and
must fit in existing clear openings; provide required anchoring, new blocking,
shims, metal/wood furring, sealants, weather-stripping, etc. for a secure, air &
weather-tight fit in the clear opening. All window openings are to be secured and
weather-tight during non-working hours.
4. Provide glazing that minimizes hazardous glazing fragments, per UFC 4-010-01
(DoD Minimum Antiterrorism Standards for Buildings).
5. Provide insulated glazing system (outer lite low E with air space (argon) and
interior lite meeting IBC requirements for wind and windborne debris protection).
6. Windows must match color of previous existing or comply with IAP (Installation
Appearance Plan); tint of glazing to match previous existing location.
7. Seal all window rough openings to prevent water & air infiltration after new window
installation; final installation must adhere to air leakage rate in accordance with
guide specifications (UFGS) and NFRC (National Fenestration Rating Council).
8. Windows to allow operable (outward awning type, per existing) use, where
applicable, with locking or latching hardware. Insect screen is to be mounted on
inside of frame of operable portion of window and must be removable.
9. Window removal and replacement work may cause damage to interior finishes or
may require destruction to accommodate work; Contractor to anticipate rework will
be required to restore these conditions to new; all new finishes (gyp bd, plastic
laminate or wood sills, ceiling soffit conditions, etc.); materials are to match
existing adjacent material, color, and texture.
10. Interior access will likely be required to perform work; interior relocation or
removal of systems furnishings (cubicles, etc.) should be anticipated - see
reference drawings in Part 6 (contractor to confirm during site visit)
