Services & Expertise

General Contracting

Traditionally, a business owner or developer hires a general contractor to assume responsibility for overseeing a construction project from beginning to end. The general contractor provides cost projections and schedules, manages the project, secures essential permits, furnishes all necessary equipment, maintains the "site general conditions" such as trailers and equipment, regulates site access and security, and engages subcontractors as needed.

With a focus on client satisfaction, SP Construction excels in project management, coordinating subcontractors, and maintaining stringent quality control. Our services encompass the orchestration of the entire construction process, from groundbreaking to the final touches. We prioritize efficiency, cost-effectiveness, and superior craftsmanship, ensuring that each project is not only completed successfully but also exceeds the expectations of our valued clients. As a beacon of reliability in the construction industry, SP Construction stands ready to turn concepts into reality, consistently delivering excellence in every aspect of general contracting services.
