operation. To preclude this in the future include the following
a) Identification of floor area required to remove
equipment components such as filters, coils, heat exchanger
tubes, bearings, etc. In equipment rooms, require that floor
space be identified by striping with yellow paint.
b) Equipment elevations and room sections to clearly
identify equipment arrangement which provides sufficient access
for equipment operation and maintenance.
c) Location of permanent ladders, catwalks, and
platforms required to access and maintain overhead equipment.
Minimize the use of elevated equipment wherever possible.
d) Use two dimensional pipe drawings (with dimensions
indicated as necessary) for congested spaces to ensure that
equipment and piping will be installed as intended with adequate
personnel space available for operation and maintenance.
Symbols and Abbreviations
General. Provide a list of symbols and abbreviations
on the title sheet of the project. Use symbols and abbreviations
that are common to the trade as contained in ASHRAE handbooks.
For larger projects, each discipline may have their corresponding
lists on the first sheet of their group of drawings.
Specifics. Limit symbols and abbreviations to items
that are actually in the project. Limit abbreviations to items
that occur more than once in the project.
Building Column Lines and Room Names. Ensure that
building column lines and room names are identical to those shown
on architectural drawings.
