Required Starting Point

Property Research & On-Site SiteWalk

Before delivery is scheduled, Property Research and an On-Site SiteWalk are required. We confirm zoning and allowed use, document setbacks and site conditions, and evaluate utility locations, access corridors, staging areas, delivery paths, fire constraints, and jurisdiction requirements. Every project receives a clear written responsibility matrix.

Site Readiness Coordination

Delivery & Placement Coordination

Utility & Inspection Coordination

Managing preliminary site prep, grading and drainage alignment, utility route clearing, staging area setup, and trade sequencing.

Overseeing transit scheduling, crane and rigging logistics when needed, crew positioning, site protection, and manufacturer guidelines.

Connecting licensed specialty trades, scheduling agency inspection sequences, tracking corrections, and achieving closeout.

Single-Point Project Management Option
