During construction, you will have two points of contact.
Your Lead Carpenter will be your primary contact, managing the day-to-day work on site, including deliveries, job site safety, the construction process, and minor change orders.
Your Project Manager will be your secondary + emergency contact. They will oversee the overall schedule, answer general questions, address any issues that come up, and facilitate major change orders. They will also meet with you weekly or biweekly to review schedule updates and keep you informed throughout the project.
