Section 4: Project Background & Project Description The intent of this project is to prevent water infiltration and damage from the capstone to the bottom of the second floor on all four sides of building ND0046ZZ. The contractor will repair caulking, repoint and seal windows, associated brick, and cap stone mortar joints. The base bid is the East side of the building, option 1 the South Side, option 2 the West side, option 3 the North side. There is also an option 4 for the contractor to remove rust and possible lead containing paint from the top lintel of all exterior windows and paint with rust inhibiting paint. The Federal Building and Post Office ND0046ZZ building is eligible for historic building listing.

Section 5: Project Objectives The contractor shall provide labor, materials, equipment and supervision necessary to perform:

a) Thoroughly inspect the caulking, mortar joints, control joints and brick at the identified windows and surrounding areas for cracks, open joints, caulk not adhering and any other means for water to infiltrate the building. The infiltration appears to increase with the presence of strong winds driving the rain into the building. The water typically is noticed at or above the lintel height.

b) The contractor shall remove and replace existing cracked and/or damaged caulking on the exterior wall areas (to include lineal areas above and around each side of windows). Sealant is to be polyurethane selected per ASTM C1193 Standard Guide for Use of Joint Sealants and suitable for adhesion to concrete and metal, standing water environment and UV resistant.

c) The windows measure approximately 20” x 72” and there is approximately 36” of masonry between each set of two.

d) There are a total of two hundred twenty eight (228) windows project with locations identified in the drawings.

e) The building cap stone and roof parapet contains several caulked joints that require repair. See drawings for details.

2 | P a g e

f) There are two control joints that run the entire perimeter of the building. The control joints may be either caulk or grout.

Inspect joints and repair as needed.

g) The contractor shall remove existing cracked and/or damaged building and masonry joints. Repair cracked masonry grout joints with new grout on exterior wall areas (to include lineal areas above and around each side of windows) PLEASE NOTE: Area for repointing will be based on inspection of each side of the building (approximate circumference -700 Ln Ft). Mortar used shall be an applicable product for masonry units used in and for North Dakota’s climate. Identify location and area of damaged brick, new replacement brick (if used) shall match existing building brick.

h) Contractor shall provide means for GSA personnel to closely inspect work while in progress.

i) A staging area will be determined by mutual agreement after contract award.

j) This information is provided for bidding purposes only. The contractor is advised to schedule a site visit through GSA

Project Manager or Property Manager. Contractor shall field-verify the exact information and dimensions required for use in completing the specified work and submitting an offer.

k) Work Area is elevated. Contractor shall provide non-penetrating roof anchoring, roof swing lift, scaffolding or lift to access elevation indicated. Lifts must be capable of reaching from the street level. All equipment shall comply with all applicable regulations.

l) Contractor shall confer with City of Fargo for compliance if sidewalk or street access is to be impaired.
