IV. Inspector Comments

V. PHOTOGRAPHS

Photo 1: Two VIMS suction point installed along left wall of garage in photo (Building 4).
Site visit performed to inspect progress of active VIMS installation on Building 4 and 5
townhomes. Was only able to access a couple of the garage areas where VIMS suction
piping had been installed during the site visit since many units had not been started or
the homeowners were not home to grant access. As stated previously, suction piping
within the units completed is routed to their respective backyards (Photo 4). Installation
of the VIMS fans, low vacuum alarms and PVC risers on the suction piping had not been
started at the time of the Site Inspection.
