TABLE 12.3 Job-Site Testing Advantages and Disadvantages

Advantages Disadvantages
Testing can be done under actual construction Extreme testing conditions of testing with
conditions at a project site mock-ups are not possible at job sites
More details of terminations and transitions can Larger envelope portions are difficult to test
be included in actual testing accurately at the job site
Costs are lower, since mock-ups are not Tests are often completed after construction
necessary to construct when problems occur

MASONRY ABSORPTION TESTING

All masonry and concrete claddings absorb water and moisture, requiring appropriate
divertor systems such as dampproofing and flashings to be installed to prevent water infil-
tration to interior spaces. Since it is expected that these finishes will absorb moisture, they
