Take necessary precautions to avoid damage to existing items to remain in place, to be reused, or to remain the property of the Government. Repair or replace damaged items as directed. Construct and maintain shoring, bracing, and supports as required. Ensure that structural elements are not overloaded. Increase structural supports or add additional supports required as a result of any cutting, removal, and demolition work performed. Overloading structural elements is prohibited. Furnish supports and reinforcement for existing construction weakened by demolition or removal work.

Repair, reinforce, or structurally replace damage as required and directed at no additional cost to the Government.

Protect electrical and mechanical services, and utilities during construction. Ensure that no elements determined to be unstable are left unsupported and place and secure bracing, shoring, or lateral supports as may be required as a result of any cutting, removal, or demolition work.

Before, during, and after demolition work, continuously evaluate the condition of the structure being demolished and take immediate action to protect all personnel working in and around the project site. Areas, sections, or components of floors, roofs, walls, or other structural elements may not be left standing without sufficient bracing, shoring, or lateral support to prevent collapse or failure while workmen are in the immediate area.

4.5.2. Masonry Repair:

Remove and clean units that have been disturbed after the mortar has stiffened, and relay with fresh mortar. Keep air spaces, cavities, chases, expansion joints, and spaces to be grouted free from mortar and other debris. Select units to be used in exposed masonry surfaces from those having the least amount of chipped edges or other imperfections detracting from the appearance of the finished work. Ensure that units being laid and surfaces to receive units are free of water film and frost. Lay solid units in a no furrowed full bed of mortar. Bevel mortar for veneer wythes and slope down toward the cavity side. Shove units into place so that the vertical joints are tight.

Completely fill vertical joints between solid units with mortar, except where indicated at control, expansion, and isolation joints. Place hollow units so that mortar extends to the depth of the face shell at heads and beds, unless otherwise indicated. Mortar will be permitted to protrude up to 1/2 inch into the space or cells to be grouted.

Provide means to prevent mortar from dropping into the space below or clean grout spaces prior to grouting. In multi-wythe construction with collar joints no more than

3/4 inch wide, bring up the inner wythe not more than 16 inches ahead of the outer wythe. Fill collar joints with mortar during the laying of the facing wythe, and filling shall not lag the laying of the facing wythe by back-buttering each unit as it is laid.

Tool mortar joints when the mortar is thumbprint hard. Tool horizontal joints after tooling vertical joints. Brush mortar joints to remove loose and excess mortar.

Mix and color match to the existing mortar. Place a mix proportion of mortar on two extra brick and allow to dry to compare to existing mortar. Several mix proportions at one time or one mix proportion at a time for evaluation. Repeat process until a mix proportion matches the color and texture of the existing mortar. Multiple colors may be required to match mortar on each building and different sides or areas of the buildings due to the existing mortar being weathered, stained, different install dates or any other conditions that have caused the existing mortar to vary in color throughout the building.

Remove mortar which has softened, loosened, cracked, or loss of depth of 1/4-inch or greater by means of a toothing chisel or pointer's grinder to a uniform depth that is twice the joint width or deeper until sound mortar is reached. Leave a clean, square face at the back of the joint for maximum contact of repointing mortar. Widening of the existing joint(s) is prohibited. Avoid damaging brick edges. Remove dust and debris from the joint by brushing, blowing with air, or rinsing with water.

Wash faces and other exposed surfaces no sooner than 72 hours after completion of the repointing replacement with water applied and a soft bristle brush, then rinsed with clean water. Discolorations which cannot be removed by these procedures, will be considered defective work. Perform cleaning work when temperature and humidity conditions allow the surfaces to dry rapidly. Protect adjacent surfaces from damage during cleaning operations.

Protect from direct sun and high winds for the first 72 hours after installation or from driving rain for the first 24 hours, using plastic sheeting if necessary. Be careful not to create a greenhouse effect by sealing off air movement to protect the wall with plastic.

4.5.3. Re-Roofing:

Remove dusting agents and dirt from membrane and substrate areas where bonding adhesives are to be applied. Apply specified adhesive evenly and continuously to substrate at rates recommended by the roof membrane manufacturer's printed application instructions. When adhesive is spray applied, roll with a paint roller to ensure proper contact and coverage. Do not apply bonding adhesive to surfaces of membrane in seam or lap areas. Allow adhesive to flash off or dry to consistency prescribed by manufacturer before adhering sheets to the substrate. Roll each sheet into adhesive slowly and evenly to avoid wrinkles; broom or roll the membrane to remove air pockets and fish mouths and to ensure full, continuous bonding of sheet to substrate.

Form field lap splices or seams as specified. Check all seams and ensure full lap seal.

Apply lap sealant to all adhesive formed seams and all cut edges of reinforced membrane materials.

Install flashing and flashing accessories as the roof membrane is installed. Apply flashing to cleaned surfaces and as recommended by the roof membrane manufacturer and as specified. Utilize cured EPDM membrane flashing and prefabricated accessory flashings to the maximum extent recommended by the roof membrane manufacturer.

Limit uncured flashing material to reinforcing inside and outside corners and angle changes in plane of membrane, and to flashing scuppers, pourable sealer pockets, and other formed penetrations or unusually shaped conditions as recommended by the roof membrane manufacturer where the use of cured material is impractical.

Extend base flashing not less than 8 inch above roofing surface and as necessary to provide for seaming overlap on roof membrane as recommended by the roof membrane manufacturer.

4.5.4. Cleaning:

No sooner than 72 hours after completion of the re-pointing and masonry replacement work, faces and other exposed surfaces of masonry shall be washed down with water applied with a soft bristle brush, then rinsed with clean water. Discolorations which cannot be removed by these procedures, shall be considered defective work. Perform cleaning work when temperature and humidity conditions allow the surfaces to dry rapidly. Protect adjacent surfaces from damage during cleaning operations.

4.5.5. Protection of Work:

Protect work against damage from subsequent operations.

4.5.6. Defective Work:

Defective work shall be repaired or replaced, as directed, using approved procedures.

4.4.1. Final Inspection:

Following completion of the work, inspect the structure for damage, staining, and other distresses. The patches shall be inspected for cracking, crazing, delamination, unsoundness, staining and other defects.

The finish, texture, color and shade, and surface tolerances of the patches shall be inspected to verify that all requirements have been met. Repair surfaces exhibiting defects as directed.

4.5.7. Site Restoration:

Conduct site restoration. Site restoration to include the removal of construction equipment and materials from the project site and the restoration of the project site to pre-project or better conditions.
