See attached Prebid Meeting Sign-in Sheet. QUESTIONS AND ANSWERS FROM PREBID MEETING Question 1: Is a General Contractor required to select low bids from SUBP companies over their own bid for sections of work that the General Contractor would prefer to self-perform in order to keep their own employees employed? Answer 1: The Contractor must still solicit bids from SUBP companies for work that they intend to self-perform. A good faith effort must be demonstrated if a SUBP company is not selected. Question 2: Can corn cob blasting be used to remove the paint over spray at the trusses? Answer 2: See Section 099300-Staining and Transparent Finishing attached with this addendum for paint removal. Question 3: Is the paint over spray visible on the existing exposed trusses typical at each truss? Answer 3: The paint over spray as seen on the existing exposed trusses is likely typical at each truss. Question 4: Are the rafter tails or other exterior trim to be replaced? Answer 4: See Sheets A200 and A201 for material conditions and treatments. Question 5: Is there separate water for Sea Salt and how will turning off the water affect them during their off season? Answer 5: Water for Sea Salt is not separate. Coordination of utilities with Sea Salt and their Phase IV Contractor will need to occur between both Contractors on site.



Question 6: Is there a drawing showing the extents of construction fencing on the site? Answer 6: The construction limits shown on 5B/T100 should not be used for construction fencing. The Contractor is to define the extents of construction fencing based on their own safety standards. A unit price for construction fencing is added to 004100R1-Bid Proposal Form attached with this addendum. Question 7: Can bidder assume tree protection fencing shown will satisfy project requirements? Answer 7: Bidder should assume tree protection amounts shown will satisfy project requirements, bidder may add more or make slight adjustments to locations if they feel necessary to keep workers off tree roots (and avoid penalties) at no additional charge to Owner. Question 8: Will Owner trim the lower branches of the oak to be surrounded by new decking? Answer 8: Owner will trim lower oak branches.

3.2 PREPARATION

A. Protection for Removal of Existing Paint: 1. General: Comply with recommendations of manufacturers of paint strippers for protecting

surrounding building surfaces against damage from exposure to their products. 2. Protect adjacent surfaces, including grass, shrubs and trees with paper, drop cloths and

other means. Items not painted which are in contact with or adjacent to painted surfaces shall be removed or protected prior to surface preparation and painting operations.

3. Waste material shall be collected at the end of each work day and disposed of in a manner consistent with local environmental regulations. It is considered Hazardous Waste.

4. Work area shall be sealed to prevent the spread of paint dust and debris beyond the work site.

5. Rags shall be disposed of nightly and removed from the building. 6. Adequate ventilation shall be provided in each area where solvents and strippers are

used. 7. A fully charged fire extinguisher suitable for solvent fires shall be kept in each area where

work is going on. 8. Contractor shall provide multiple fans with high CFM to move fumes out of the building

manufacturer of the product being used. 11. After paint removal is complete, areas around the site shall be cleaned of paint dust and

debris, and such debris shall be properly disposed of in a manner consistent with local environmental regulations.

B. Removal of Existing Paint Materials: 1. Paint removal may be accomplished by the following approved methods:

a. Mechanical methods including dry scraping, sanding, or wire brushing. Use methods to limit dust debris.

b. Heat guns and scraping of softened paint materials. c. Wet Mechanical Methods: Existing item preparation shall be wet scraping,

sanding, or wire brushing. d. Chemical Methods:

1) Surface Preparation: Use scrapers of a variety of sizes and shapes, whose edges have been rounded, to remove loose paint before removal using chemicals.

2) Apply chemical stripper using a brush or roller. Follow manufacturer's instructions.

3) Allow stripper to stand for length of time as recommended by manufacturer, depending upon the number of surface layers to be stripped; if necessary, cover with plastic sheeting to keep the stripper moist.

4) Using a broad knife or scrapper, remove paint and stripper from the surface. 5) Safely dispose of paint and stripper residue. 6) Note: Do not use water on wood surface. 7) Wipe wood with a clean cloth soaked in mineral spirits to remove chemical

residue or other method as recommended by the chemical stripper manufacturer.



8) Allow to dry and dry-brush loose material from the surface using a short fiber bristle brush.

9) Repeat as necessary to sufficiently remove the previous coating.

C. Comply with manufacturer's written instructions and recommendations in "MPI Architectural Painting Specification Manual" applicable to substrates indicated.

D. Remove hardware, covers, plates, and similar items already in place that are removable. If removal is impractical or impossible because of size or weight of item, provide surface-applied protection before surface preparation and finishing. 1. After completing finishing operations, use workers skilled in the trades involved to

reinstall items that were removed. Remove surface-applied protection if any.

E. Clean and prepare surfaces to be finished according to manufacturer's written instructions for each particular substrate condition and as specified. 1. Remove dust, dirt, oil, and grease by washing with a detergent solution; rinse thoroughly
