The fourth biweekly status meeting took place mid-morning. Attending were:

• Prostar
• Strata Engineering
• Sub contractor reps
• Copperstone Council, represented by the President and Vice President
• Quay Pacific strata property manager

Concerns over the quality of work and schedule were raised by the Vice President. Prostar again promised to provide a schedule to owners, and also stated they would be ready to install the new membrane by the end of this week, weather permitting.

Work done today:

• Continued use of pressure washers to remove membrane material/residue
• Workers observed onsite: Three

Addendum: Later in the afternoon, the Vice President noted the site had gone quiet and at first assumed work had been completed for the day. He went outside and found two workers struggling to get a power washer started, repeatedly pulling hard on the pull cord of the unit. The Vice President observed the power switch was in the OFF position and pointed this out. The workers turned the power switch to ON and were able to start the power washer and resume work. While anyone can make mistakes, this does raise concerns over the quality of work being done.
