9.2The top of the tower shall be equipped with a sturdy 42" high guardrail sys- tem, complete with top rails, interme- diate rails and toeboards, conforming to OSHA standards. Guardrails and posts shall consist of 1.66" O.D. x 15 gauge galvanized structural tubing. Posts shall be spaced on centers of 8'- 0" or less.

9.3One 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.

10.0Cold Water Collection Basin:

10.1The collection basin shall be heavy- gauge galvanized steel and shall include the number and type of suction connections required to accommodate the out-flow piping system shown on the plans. Suction connections shall be equipped with debris screens. A fac- tory installed, float operated, mechani- cal make-up valve shall be included. An overflow and drain connection shall be provided in each cell of the tower. The basin floor shall slope toward the drain to allow complete flush out of debris and silt which may accumulate.

11.0Scope of Work:

11.1The 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.

tion, alerting you to a potential maintenance head- ache.

Good maintenance practice requires period- ic access to the top of the tower to inspect the distribution basins, as well as the struc- tural integrity of the fan deck, fan cylinder, and fan — especially the fan blade secur- ing hardware. There are no induced-draft cooling tower designs that are immune to this need!

For the comfort and safety of your operating personnel, the Sigma Steel tower includes a ladder and guardrail of the quality and design indicated — and we strongly recommend that you require it of all bid- ders! 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 steel cold water collection basin indi- cated on page 24 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 misunderstandings during
