They concluded that a prescriptive specification
requiring 35 percent cement replacement by volume with fly ash will reduce the damage due to calcium oxychloride formation.
Typically, when writing a prescriptive specification, the engineer must know exactly how the product should be installed and what is expected for the finished product.
Like prescriptive specifications, performance specifications are very detailed but eliminate unnecessary "how to" and "review/approve all steps and processes" and allow the Contractor to provide the best means and methods for completing the project on time and on budget.
A prescriptive specification
describes a product predominantly by its composition, while a performance specification describes how well a product must perform.
In this case, the state hopes doing so will help it avoid overly prescriptive specifications
and encourage innovation and a broader range of solutions on the part of proposers.
MATERIALS TESTING IS A CRITICAL ISSUE FOR PLASTICS COMPOUND AND MASTERBATCH PRODUCERS WHO MUST FULFIL CUSTOMER REQUIREMENTS AND DEMONSTRATE THAT THEIR PRODUCTS SATISFY PRESCRIPTIVE SPECIFICATIONS
. LABORATORIES CONTINUALLY STRIVE FOR ACCURACY AND REPRODUCIBILITY AND NEW DEVELOPMENTS SUCH AS AUTOMATED FEATURES AND INDUSTRY STANDARD SOFTWARE CAN HELP MEET THESE GOALS.
The use of performance specifications, as opposed to traditional prescriptive specifications
, encourages innovation in design and construction.
of more standard column and slab mixes, is sure to instill confidence in prospects open to Breckenridge Material's case for performance versus prescriptive specifications
Construction codes for concrete today are based largely on prescriptive specifications
. Specifications that are performance-based, however, would allow green concrete to compete with standard concrete as tong as the performance meets the buyer's requirements."
