The Reference Guide states that the project needs to "Keep a log for the repair and maintenance of any cleaning equipment used at the project site". The sample maintenance log shows equipment type, daily, weekly, bi-weekly, monthly, and quarterly maintenance. However, the description of a "log" implies that dates or initials would be required. This seems over the top for LEED to require signatures for daily tasks... should we follow the LEED reference guide sample? Or is it implied that initials and dates are also necessary?
