At Keystone DCS, Inc., we ensure our customers’ needs are met, and expectation is exceeded. We will provide exceptional construction services by managing each project with effective communication and close supervision. Working closely with our architects, project managers, and onsite supervisors, we will be able to oversee all aspects of the project to ensure all phases, from pre-construction planning and architectural design to post-construction, happen correctly according to schedule.
Construction Management and On-Site Supervision
Most construction managers supervise only the construction portion of the project. However, at Keystone DCS, our construction management services begin from project’s beginning phases to completion. Keystone’s construction managers will be on site every single day to ensure all aspects of the project are happening correctly and according to the designated timeline.
General Contracting
We can handle all general contracting duties when it comes to the structural electrical, mechanical, plumbing engineering, and many other elements of our clients’ project. Keystone DCS, Inc. is the only point of contact our clients will deal with for the entire project.
Project Management
Keystone’s project manager will ensure the project runs smoothly, stays on schedule, and on budget. Our project managers will oversee all aspects of the project’s pre-construction, construction, and post-construction phases.
Safety
Keystone DCS maintains a commitment to safety in the field. All members of our team, including architects, project and construction managers, and builders work hard to ensure safe and healthy working conditions. This includes instructing employees in safe job site practices and informing workers beforehand of potential workplace hazards.
Keystone DCS is an OSHA Partnering Agreement Member. All job sites and equipment used follows all OSHA regulations. Throughout each project, we also ensure any partners and subcontractors follow the same commitment to worker safety and health.
