3. Conclusions and Summary

In our opinion, the following work must be performed:

1. The roof must be coated to extend its life. Replacing the roof would require
compliance with the current building code. The code now requires additional
ridged insulation what would require significant adjustments to the penetration on
the roof. If the roof drainage is improved by installing larger pipes from the roof,
we believe that a coating can successfully extend the life of the existing roof by 5
to 10 years and is a cost-effective solution. Without improved drainage, water
standing on the roof would accumulate and cause the roof coating to fail
prematurely.

2. The small space between your building and the building to the left should be
accessed. Removal of trash and debris and repairs to the brickwork mortar will be
required. We strongly believe some type of awning or flashing should be installed
to prevent rainwater from entering this space, as it is saturating the brickwork on
your first floor, causing damage and promoting mold growth to intersecting
sheetrock walls.

3. Your HVAC contractor should inspect the building and improve the ductwork to
register seals. The current building code requires that all these members be
double-sealed. When these systems were installed, only a single seal was
required. Minimizing ductwork leakage will improve energy efficiency, minimize
mold growth and deliver better comfort.

4. Your HVAC contractor should re-direct flows from registers away from interior
ceilings and walls. Discharging cold air in this manner promotes condensation and
mold growth.

5. Your HVAC contractor should monitor relative humidity throughout the building.
Proper humidity control is imperative in controlling mold growth. Poor indoor air
quality from mold growth can almost always be traced to elevated relative
humidity.

6. Your sprinkler company should install the double backflow preventers required
by the City. These will cause some degree of a loss of pressure throughout the
building, but they are necessary to prevent water from your sprinkler piping from
contaminating other drinking water in the event of a loss of water pressure. If,
after the backflow preventers are installed, you find that your water pressure on
the upper floors is inadequate, you can install a booster pump to ensure proper
water pressure throughout the building.

7. Mold growth on sheetrock in the sprinkler closet should be removed. Because
there is more than 10 square feet of visible mold, the EPA guidelines require that
a licensed mold remediator preform this work.
