Specifications: Base

9.3 Each endwall of the tower shall be
equipped with a 20" wide aluminum
vertical ladder, through-bolted to the
endwall structure. Ladder shall rise
from the cold water basin level to the
top of the fan deck guardrail, and shall
be designed and installed in confor-
mance with OSHA standards.
10.0 Cold Water Collection Basin:
10.1 The cold water collection basin shall be
of poured-in-place concrete, provided
under scope of work done by others.
The concrete basin design shall be
based upon certified loads and dimen-
sions provided by the cooling tower
manufacturer.
11.0 Scope of Work:
11.1 The cooling tower manufacturer shall
be responsible for the design, fabrica-
tion, and delivery of materials to the
project site, and for the erection of
the tower over supports provided by
others. Unless otherwise specified, all
external piping, pumps, controls, and
electrical wiring will be outside the
cooling tower manufacturer's scope of
work.
For the comfort and safety of your operat-
ing personnel, the Sigma tower includes a
ladder and guardrail of the quality and
design indicated—and we strongly
recommend that you require it of all
bidders! Portable ladders and other
“make-do” access means are inappro-
priate for equipment of this size and
complexity.
■ This basic specification assumes that the tower will be erected
over a concrete basin at grade level. If the tower is to be installed
on an elevated supporting platform, the plywood cold water
collection basin indicated on page 17 should be included in the
specifications.
■ Please be clear in your specifications
and inquiry documents regarding
the full scope of work expected.
That will help assure that your bid
comparisons will be made on as
equal a basis as possible—and
will help to avoid any misunder-
standings during the execution
and implementation of the
contract.
