The structural frame of the building sets the trend for what will happen throughout the project. That is why it is often advantageous for the general contractor to self-perform the core structural work.
A self-performing general contractor establishes project goals and expectations early on and keeps the team focused and on task.
Self-performed contracting is better management of owner-initiated design changes.
More effective and efficient communication between the owner and general contractor, makes for less re-work.
When a contractor is self-performing a project it is much easier to keep a grasp on the daily clean-up and safety issues.
Contractors who regularly self-perform must have a strong infrastructure of craftsmen and project managers who are successful working as a team.
