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)

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

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
![Page 13: Product Evaluation ACT 380 1. Objective O Emphasize the importance of proper product evaluation and selection O Develop insight into effective procedures,](https://reader035.vdocument.in/reader035/viewer/2022081515/56649dea5503460f94ae5b66/html5/thumbnails/13.jpg)
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

Products Which May Be Suitable
O Resilient tile flooringO Resilient sheet flooringO Resinous flooring

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
![Page 16: Product Evaluation ACT 380 1. Objective O Emphasize the importance of proper product evaluation and selection O Develop insight into effective procedures,](https://reader035.vdocument.in/reader035/viewer/2022081515/56649dea5503460f94ae5b66/html5/thumbnails/16.jpg)
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
![Page 17: Product Evaluation ACT 380 1. Objective O Emphasize the importance of proper product evaluation and selection O Develop insight into effective procedures,](https://reader035.vdocument.in/reader035/viewer/2022081515/56649dea5503460f94ae5b66/html5/thumbnails/17.jpg)
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

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

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)
