Lecture 15 Specifications

• CEE 474 Engineering Project Management

2
Classification of Specifications

• Functional
• Design
• Performance
• Combination
• Brand Name or Equal

3
Classification of Specifications

• Functional A description of the essential
  physical characteristics and functions required
  to meet minimum needs. The use of a functional
  specification allows prospective contractors to
  offer a variety of products or services which
  will perform the specified functions.
• (A four door car with seating for 5 adults)

4
Classification of Specifications

• Design Specification describes in detail the
  materials to be used, their sizes and shapes, and
  how the item is to be fabricated and built. It
  provides a completely defined item capable of
  manufacture by a competent manufacturer in the
  industry
• (A four door car with a 2.4-liter DOHC 16-valve
  VVT-i 4-cylinder, 158 hp _at_ 6000 rpm/161 lb.-ft.
  _at_ 4000 rpm, Electronically controlled
  continuously variable transmission (ECVT),
  MacPherson strut front suspension with gas-filled
  shock absorbers and stabilizer bar dual-link
  independent MacPherson strut rear suspension with
  gas-filled shock absorbers and stabilizer bar (SE
  adds sport-tuned shock absorbers and springs,
  strut tower and trunk-mounted braces), etc., etc.)

5
Classification of Specifications

• Performance Specification expresses the
  requirements in terms of ranges of acceptance
  characteristics or minimum acceptable standards,
  such as minimum and maximum capacity, function,
  velocity, or operation of equipment. In this type
  of specifications the details of design,
  fabrication and internal structure are left to
  the option of the contractor, except certain
  features or parts may be specifically required.
• City mileage 20 -25 mpg, highway 30 mpg minimum,
  coefficient of drag maximum 0.30, ground
  clearance 5.0 to 6.0 inches, curb weight 3,000 to
  3,500 pounds, trunk capacity 14 to 16 cubic feet,
  etc., etc.
