Poor scheduling, inadequate subcontractor oversight, and failing to protect existing finishes are the most frequent contractor errors. Common issues include trades showing up out of sequence, causing rework and delays, drywall crews starting before plumbing and electrical inspections pass, and workers damaging existing flooring, countertops, or fixtures in areas adjacent to the construction zone. Communication breakdowns between the general contractor and subcontractors also lead to details being missed or executed incorrectly. Kingdom & Co. assigns a dedicated project manager to every job who coordinates trade scheduling, enforces site protection protocols, and conducts daily quality checks.
