1. PROJECT: Burlington, VT (BTV) Air Traffic Control Tower (ATCT) Brick Veneer Repair Project

2. ADDRESS: 1200 Airport Drive, Burlington, VT, 05401

3. DESCRIPTION: The BTV ATCT facility was built in 1993 and consists of an 80 foot tall air traffic control tower and a single story, 9300 square foot base building and link. The purpose of the brick veneer repair project is to repair defects in the brick veneer exterior of the base building and link due to suspected water infiltration, saturation and freeze/thaw effects. The defects in the brick veneer include efflorescence build up, spalling, cracking, loose/missing brick, deteriorated mortar joints and inconsistent drainage from weepholes. There are no structural cracks or bows in the wall.

4. GENERAL: The Contractor must provide all material, equipment, supplies, transportation and labor to complete the specific scope of work. All work to be priced out in accordance with David-Bacon Wage rates.

5. SCOPE OF WORK:

1. Remove and dispose of any mortar at the mortar joint at the lintel face of each corbel and install new commercial grade sealant at the joint throughout the base building exterior. Ensure open head weeps are installed within the sealant.

2. Install new open head weep holes at the section of existing sealant that was installed by others.

3. Install new open head weepholes every 2’ at the following locations:

a. Top of the corbel, directly above the top brick and at the bottom of the flashing throughout the entire base building and link.

b. Just below the rowlock course/window sill at the bottom of the flashing.

c. Soldier course at the base building sidewalk.

d. Above the windows directly above the first brick at the bottom of the flashing.

4. Install new open cell weep hole mesh at all new weepholes above the soldier course brick.

5. Install new stainless steel weep hole covers at new weepholes at the soldier course brick above the sidewalk.

6. At the south wall at one window, remove and dispose of entire rowlock course. Sawcut ~3/4” and remove section of brick. Install new brick and mortar to achieve proper slope (20%) to match other sills.

7. Remove and dispose of any loose, cracked, spalled or damaged brick and replace with new.

8. Remove any deteriorated mortar and install new.

9. Remove efflorescence build up by applying efflorescence remover. Wash and brush areas of mildew and dirt on brick veneer.

10. Pressure wash all surfaces of brick veneer to remove any dirt buildup. Limit PSI of pressure wash so as to not damage brick.

11. Install a new 2’ wide by 1.5’ deep trench as shown in sheet C001 and C002. Install new landscape fabric along all surface of new trench and fill trench with ¾” crushed stone.

**NOTE: Appendix A Site Pictures shows large bushes and mulch in front of the base building. These have since been removed and replaced with gravel.
