Product Evaluation
ACT 380
1
ObjectiveO Emphasize the importance of proper
product evaluation and selectionO Develop insight into effective
procedures, methods, and techniques in evaluating and selecting products
2
Major TopicsO Establish the Requirements
O Safety & ProtectionO Functional CharacteristicsO Material CompatibilityO Codes, Standards, and References
O Identify ProductsO ManufacturersO Code RequirementsO Installation RequirementsO Product Characteristics
O Evaluate ProductsO Installation RequirementsO MaintenanceO QualificationsO PriceO Warranty
3
Product Performance Requirements
O Safety and ProtectionO Fire safetyO Life Safety (other than fire)O Property Protection/SecurityO Accessibility
4
Functional Characteristics
O StrengthO DurabilityO Stain ResistanceO Transmission
CharacteristicsO Waste Products &
DischargeO Operational
Characteristics
O Aesthetic Properties
O Acoustic Properties
O IlluminationO VentilationO Measurable
CharacteristicsO Material
Properties5
Practical Characteristics
O Interface Characteristics (compatibility with other materials)
O ServiceO ReplaceabilityO Personnel Needs
6
Example of Compatibility Issues
O Copper flashing used on structure containing aluminum windowsO When condensation drips from the
copper flashing it will cause the aluminum window frame to corrode (galvanic series)
7
System Compatibility Issues
O A 5 foot light fixture has been selected to be used with a suspended ceiling systemO The ceiling suspension system and
acoustical panels selected must be compatible with the light fixture
8
CostO Material costO Installation costO Initial cost – material & installationO Life-Cycle cost/ Value engineering
9
Legal RequirementO Case StudiesO Other Legal StudiesO FailuresO Errors & OmissionsO ProblemsO Legislation
10
Codes, Standards, and References
O Codes & RegulationsO StandardsO Testing, InspectionO IndexesO DirectoriesO Symposia, Technical MeetingsO Research and Development
11
Checklist ApproachO Often a “checklist” approach is used
to determine product requirementsO Example problem: You are to select
a floor covering for an assembly room in an electronics manufacturing plant. What are some of your considerations in selecting the proper product?
12
Possible ConsiderationsO Fire Safety- Class A material, flame-spread rating
0-25O Accessibility- wheelchair accessibleO Strength- subject to loads from 2-wheel dollies
(hand trucks)O Durability- no chemicals will be used in this roomO Stain resistance- high degree of sanitation required
(washed often- considerable amount of foot traffic)O Aesthetic properties- owners prefer light colors
with low light-reflectivityO Material properties- static resistance of 2.5KVO Interface characteristics- compatibility of material
to subsurfaceO Service – 10 year life minimum
13
Products Which May Be Suitable
O Resilient tile flooringO Resilient sheet flooringO Resinous flooring
14
Identifying ProductsO A generic product that meets project
conditions and satisfies criteria is selected initially (e.g., “high-pressure plastic laminate” and not “Formica”)
15
Resources for Identifying Products
O Manufacturer’s product dataO Sweet’s Catalog O Manufacturer’s representativesO Professional and Trade associationsO Technical manualsO Trade shows
16
Evaluating ProductsO Once a few possible products have been
identified, the A/E should evaluate each and select the most appropriate for the given project
O Selection Criteria:O The top priority is whether the product
meets code requirementsO Next is the visual acceptability (are designs
& colors satisfactory)O Does manufacturer recommend this
product for the intended useO Does the product have
limitations/advantagesO What is the product performance history
17
Installation Requirements
O Considerations:O Do installation requirements address this
projects site conditions (weather, if portion of the site is occupied)
O Is there any need for special skilled installers
O How will damaged goods (during shipping or construction) be replaced
O Will product fit through existing openingsO Does the product emit any fumes or odors
during installation18
CostO Installed cost is a key concern;
although a product may not be costly, sometimes installation is very costly
O Life-cycle cost is sometimes a more appropriate measure of value
19
Maintenance Requirements
O Maintenance can add a large amount of money to the product selected
O Sometimes details are OVERLOOKED that cause problems later (motor placed out of reach for maintaining, filters needing replacing- no access to them planned, is a special mechanic required to service equipment- often costly and time sensitive to locate and bring to the project site)
