of the STP deals with issues of construction. Documentation and evaluation will be made
of specific constructability issues. These issues include:
a) Manpower requirements
b) Foundation requirements
c) Material and equipment required
d) Ease of construction
e) Construction duration
f) Special construction considerations.
g) Application limitations
h) Damage during construction
The vendor will arrive on-site with all supplies and materials (except fill) loaded in one
or more trucks, similar to transporting the product to a remote levee site. Fill material
may be stockpiled at a designated location outside the test facility. No materials will be
unloaded from the trucks until initiation of the testing protocol. A waterproof gate to the
test basin will be open and small front end loaders or similar equipment way be used to
aid in construction of the IFFS. When construction is complete, the gate to the test basin
will be closed and no further access to the IFFS with mechanized equipment will be
possible until after the overtopping test is completed.
At the completion of the tests, the vendor will disassemble the IFFS and return it to the
truck(s) for removal. Suitability of the IFFS for reuse will be considered.
6.0 Hydrostatic Testing Protocol
The initial and most basic component of the STP is to evaluate the structural and
hydraulic response of each IFFS to quasi-static, slowly rising hydrostatic head. The
testing protocol for the hydrostatic head test will consist of flooding the basin on the
river-side (or "wet" side) of the barrier or wall to the desired water level. Three water
levels will be used for testing: 33-1/3%, 66-2/3%, and 95% of the height of the structure,
also shown in Attachment 2. At each increment, the water level will be held at constant
stage for a minimum of 22 hours. Continuous measurements will be made of seepages
