CYPRESS, CALIFORNIA 90630
PART 1 – GENERAL
1.01 Scope of Work and Special Project Conditions
A. Base Bid: The Contractor shall supply all permits, labor, transportation, materials,
apparatus, and tools necessary for the installation of fluid-applied pedestrian coating
system over the Piazza deck of Building 8 located on the campus of Cypress College. This
work includes the replacement of existing expansion flashing assemblies at “tie-ins” to
adjoining walkways and decks.
B. Approximate Waterproofing Area: 21,589 square feet.
NOTE: Contractor must field verify all dimensions as estimated square footage totals are provided
in “plan view”.
C. Existing Waterproofing System Description: The existing deck is a pre-stained concrete
slab with no type of exposed waterproofing/coating system currently present. The
between slab waterproofing is believed to be a fabric reinforced fluid-applied and
urethane-based waterproofing membrane with protection material.
D. New Waterproofing System Description: The new coating system shall be consist of a
fluid-applied, pedestrian traffic coating system comprised of a base coat, wearing surface
coat, aggregate, and finish coat applications to achieve a minimum dry film thickness of
74 mils, less primer. This system is to be installed over a resin-based membrane forming
moisture mitigation system/primer.
E. The general waterproofing coating system installation scope of work shall include:
1. The removal, temporary storage, and reinstallation of the existing concrete trash
containers and steel benches. Containers damaged or broken during this process
are to be replaced at no cost to the District.

2. The proper preparation of membrane surfaces is to include cleaning and removal of
foreign substances such as calcium deposits, algae, soot, surface rust, and heavy
moisture staining. Work to include the cleaning of substrate surfaces by means of
power washing and brooming with a mild biodegradable detergent.
3. To verify bonding compatibility of the new pedestrian coatings and post cleaning of
existing substrate surfaces, the Contractor is to perform one of the following
adhesion tests:
a. ASTM D4541: Test requires the use of an elcometer and provides a “pull-
off” value.
b. ASTM D903: Standard test method for peel or stripping of adhesive bonds.
4. The repair of existing cracks in the concrete surfaces. Cracks less than 1/16 inch in
width are to be sealed with specified urethane-based sealant. Cracks greater than
1/16 inch in width are to be properly sealed using rigid foam backer rod, bond
breaker tape, and specified polyurethane sealant. Detail completed sealant repairs
with a minimum 30-mil application of specified urethane base coat. Cracks are to
be prepared but not sealed until post curing of the specified moisture
mitigation/primer system.
5. The stairwell landings shall receive two (2) coats of wearing surface application
including aggregate.
F. Special project conditions to be included in the scope of work:
1. The finished coating is to be two (2) different colors, which closely match the existing
color scheme and footprint or as otherwise approved through the material submittal
process using standard colors.
2. The finished coating assembly is to extend into the double doors of the raised
penthouse roof structure located near the southeast corner of the building and is to
fully cover the exposed mechanical room floor.

3. At low perimeter curb walls, the removal and salvage of the existing sheet metal
counterflashing assembly to allow for the installation of the specified waterproofing
system and related flashing components. The new waterproofing system is to
extend a minimum of 2 inches onto the sloped surface of the exterior portion of the
wall assembly, but is to be completely concealed from view by the horizontal flange
of the counterflashing. Upon completion, the flashings are to be restored and
reinstalled using fasteners that are one size larger in diameter than existing fasteners
and equipped with a steel and rubberized washer. Restoration work is to include
the treatment of flashing surfaces with a rust inhibitive primer and two (2) coats of
exterior grade enamel paint. Color of point to closely match existing or as approved
by the District through the material submittal process.
4. At raised concrete curbs, the removal, salvage, and reinstallation of steel rail stops
to allow for the continuous and uninterrupted installation of the specified
waterproofing coating system. Once completed, the rail stops are to be reinstalled
using appropriate fasteners one size larger in diameter than existing. Fastener holes
are to be injected with urethane sealant and rail stops are to be set into a continuous
bed of sealant over the cured coating system.
5. The restoration of existing deck drains to include; the replacement of broken
clamping ring/strainer fasteners with new fasteners to match existing and the
replacement of existing strainers with new corrosion resistant strainers such as brass
or stainless steel. New strainers are to be size appropriate to properly fit existing
drain openings. This work shall also include the water test of drain lines to ensure
lines are free flowing and free of obstructions. The Contractor will be responsible
for the first 10 lineal feet of each drain line.
6. The restoration of the existing expansion flashing and cover plate assembly at each
of the three (3) deck transitions to adjacent walkways. This work is to includes but
may not be limited too; the removal and replacement of the existing sheet metal
cover plates with new stainless steel slip resistant cover/slide plates, the replacement
of the existing expandable seal with a new continuous and expandable locking wing
seal with drain system, and replacement of vertical and horizontal joint seals at
exterior walls and soffit areas with a new engineered and prefabricated silicone joint
sealing system. Finished work is to result in a fully-functional watertight assembly
with proper drainage.
