Each portion of the project was phased from demolition to roof replacement to maintain occupancy and allow the continuous operation of the branch. All service outages were scheduled for off hours. The removal and replacement of the drive thru canopy associated pneumatic system and concrete drive islands were scheduled in detail to ensure safety and allow transactions to be conducted. Ramps and overhead protection were constructed, dismantled, and reinstalled for each phase of construction. Restroom facilities, security systems, heating and cooling, fire alarm and data were required to be available and maintained 24 / 7 throughout construction. The delivery of material and equipment and the use of same on site required to be carefully coordinated to allow the bank customers and employees access to the site. The replacement of the existing roof storefront systems and glass and glazing was conducted with no water intrusion. During the final phase of construction, a temporary teller line and support offices were constructed to allow bank services to continue. The temporary space included a millwork teller desk, safe, security, check writing desk, modular partitions, and data. While this space served most of the customer needs the safe deposit boxes remained in the main bank vault located in the last phase of the renovation. Access to the vault was required throughout the day and customers were required to be escorted by bank officials and site management to ensure they had a safe and secure path to conduct business.
