Re : B rettel berg Wal kway Reconstru ction, Proj ect #2020-396.00 I
Dear Leonard,
Based on our recent conversations, I understand that you will be undertaking repair and
replacement of portions of the waterproofing and walkways on the exterior of the buildings this
summer. Based on our observations and reviews of the building last summer, we have the
followin g recommendations:
1. The existing walkway decking, waterproofing, and any underlayment should be removed
down to the bare concrete.
2. Observation and assessment of the structural condition of the concrete plank floor
structure should be conducted in all replacement areas. The floor should be assessed for
structural damage from water infiltration and degradation of the concrete and the internal
reinforcing. Any significant areas of damage discovered will require formulation of repair
plans and specifications at that time.
3. New waterproofing and decking should be installed. We recommend that tapered rigid
insulation be used to provide positive drainage to the rooftop drain system. A minimum of
1/8 inch per foot is generally recommended by roofing manufacturers of low slope
membrane roofs, but this should be confirmed with the roofing supplier. Polyisocyanurate
or other closed cell foam insulation is typically used for tapered rigid insulation
applications. A cover board over the tapered rigid insulation is required for durability of
the roofing and to provide a stable surface for foot trafiic. Glass mat faced gypsum
boards such as Dens-deck or a perlite based cover board are typically used and are
recommended in this situation.
We look foruvard to continuing to assist you with your building maintenance needs however we
can. lf you have any questions, or wish to discuss our recommendations, please contact me
however you find most convenient.
Sincerely,
John E. Partch,E,
Senior Engineer
