             JOB-SITE TESTING

                         Tests done at a job site can be as simple or as scientific as required by immediate concerns.
                         Simple water testing using a garden hose and water source is probably the most frequently
                         used means of job-site testing on both new and existing envelopes. Static and dynamic
                         pressure testing can also be accomplished at project sites by laboratories or consulting
                         firms that can provide portable equipment to complete these types of tests, (Fig. 12.16).
