Prepare a useful South Mountain site brief
- Address and access. Share the exact site, placement surface, clearance, turning route and unloading point.
- Operations. State the dates, staffing or visitor pattern, daily volume and any restrictions on deliveries or servicing.
- Utilities. Document available power, potable water, wastewater arrangements and who will approve connections.
- Equipment fit. Describe the function, capacity and workflow so the team can check a proposed unit rather than relying on a category name alone.
