e. Loads: Describe the total connected load and resulting kilowatt demand load by
applying proper demand and diversity factors, if a group of loads is involved.
f. Transformers: Describe type of transformer to be used, coolant, rating, protective
devices, and connection.
6.10.3 Instrumentation And Control Systems
a. Describe the overall process to be controlled and the control philosophy.
Indicate the control system inputs from the process and the control system outputs to
the process. Describe the process sensors and signals, the control system signals
and actuating devices. Describe the control algorithms to be implemented. Provide
a general sequence of operations. Indicate a typical functional diagram for control
of the major process similar to a Scientific Apparatus Makers Association (SAMA)
diagram or a function blockwire diagram.
b. Describe the control equipment signal processing scheme, i.e., electric analog
or digital; single processor or distributed processors; programmable logic controller
based; personal computer based; single loop controller based; multi-loop controller
based; or mini-computer based. Indicate the expected update frequency for critical,
typical and non-critical data points in the system. Indicate the expected end-to-end
control accuracies.
c. Describe the hard wired control logic scheme and provide a typical ladder logic
diagram to illustrate the method to be used on the contract drawings.
d. Describe the control program programming scheme, ladder diagram logic,
function block logic and a typical diagram to illustrate the method to be used on the
contract drawings.
Reference all appropriate criteria requirements applicable to the project and explain how
these requirements will be incorporated into the design. At a minimum, the following fire
protection provisions shall be addressed:
a. Type of construction and interior finishes.
b. Classification of occupancy.
c. Building separations and exposure protection (between project building and
surrounding buildings); remedial action required if project involves an existing
