spec writing principles
"It is an old observation that the best writers sometimes disregard the rules of rhetoric. When they do so, however, the reader will usually find in the sentence some compensating merit, attained at the cost of the violation. Unless he is certain of doing as well, he will probably do best to follow the rules."
methods of specifying
descriptive

performance

reference standard

proprietary
detailed description of the characteristics, physical properties, or workmanship.
4 c's of specifying
specifications should be:

clear - Avoid ambiguity, specs should not be unenforceable or subjective

complete - Brevity at the expense of completeness should be avoided

concise - Eliminate superfluous words

correct - Proper terminology is important

spec writer's MOTTO
"say it once, say it right, and say it in the right place"
Spec Language
addressed to the contractor

written in the imperative mood

mandatory language

streamlined
streamlined specs
use key heading to identify subject

not proper English, but proper specifying

use colon to mean "shall" or "shall be"
examples
lightweight aggregate: astm c330

Descriptive
a statement of required results and criteria by which the performance will be verified.
performance
Reference is made to established standards to which the specified product and processes shall comply or conform
reference standard
Actual brand names, model numbers, products are specified
(substitutions may or may not be permitted)
proprietary
concrete anchors: mild carbon steel, zinc-plated (min. 5 µm), Externally threaded sleeve type anchor tested for use in cracked concrete.
examples:
concrete anchors: 5,000 lb min tension capacity based on aci 318-11, appendix d
concrete anchors: tested in accordance with aci 355.2-07
concrete anchors: hilti kb-tZ, carbon steel

linking specs to bim model
future:
Will bim models replace specification books and project manuals?
not in the foreseeable future!
Coordinate drawings & specs
delineate info in drawings vs specs
coordinate terms used
avoid repeating information
use generic terms in drawings
master list of numbers and titles
Final recommendations:
subscribe to commercial master guide spec
office level
project level
use "Edit by Deletion" or "Edit by Selection" method for editing master specs for project
establish and maintain office master spec library
coordinate drawings with specs
Understand & follow csi standards
coordinate technical specs with division 1
Principal / Management Level
Encourage engineers to learn and follow csi & AIA principles and standards
