CDT Review - Chapter 10, Product Selection and Evaluation

Chapter 10 Product Selection and Evaluation develops the concept of the dual nature of design, which was first introduced in Chapter 8 (Design). There is a direct relation between who develops the documents and the project delivery method selected.

Through product selection is required to:

  • Establish performance requirements for products, assemblies, equipment, as well as the facility itself.
  • Identify types of products with attributes that comply with the performance requirements that are established for the project.
  • Obtain product information from product representatives.
  • Select specific products based on their history of perfomance in like applications, their compatibility with other selected products, and their life cycle value.
  • Consider alternatives.
  • Present product selections to the owner.
  • Document Selections.

Types of Products
Know definition of term product, which can be categorized into various types.

  • Materials
  • Commodities
  • Products
    • Standard Products
    • Custom Products
      When evaluating custom products, note the following possible considerations:
      • Prepayment
      • Submittals
      • Minimum Purchase Orders
      • Custom Colors
      • Lead Time
      • Testing and Certification
      • Proprietary Products
    • Assemblies/Fabrications
    • Equipment

Importance of Product Selection and Evaluation
Select appropriately for the project and their completed facility. Review possible questions to consider, before deciding on a product. (Review PDPG - Chapter 10, p. 192.)

Obtaining Product Information
Note influence of the Internet in the selection process. Note list of sources of information about the aesthetic and technical aspects of a product. (Review PDPG - Chapter 10, p. 193.)

The Evaluation and Selection Process
Note the relation between effective evaluation and selection products with the decision-making process.

  • Initial Product Identification
  • Establishing Product Criteria
    • The Nature of Attributes - Three considerations:
      • Requirements
      • Criteria
      • Tests
        Note Figure 10.1, a reference guide example.
    • Project Requirements - The project schedule has two basic influences:
      • Schedule for design delivery
      • Product delivery
    • Project Delivery
      Note Table 10.1 on "Project Stages, Decisions, and Information Needs."
  • Determining Applicable Criteria
  • Attribute Categories for Evaluation
    Review PDPG - Chapter 10, pages 203-209.
    • General Considerations
    • Physical Properties
    • Performance
    • Sustainability
    • Safety and Protection
    • Manufacturers
