Process
Our Commercial Renovation Process
Commercial renovation projects in Irving follow a delivery sequence shaped by the occupied-facility management requirements, the City of Irving permit process for building alterations, and the specific condition of the building systems being upgraded. The steps below reflect how we manage that sequence for Las Colinas office and Heritage District commercial renovation clients.
Step
Existing building assessment and renovation scope definition
We begin commercial renovation projects with a site investigation that documents existing MEP system conditions, identifies hazardous materials requiring abatement, reviews the as-built drawings for accuracy against current field conditions, and confirms the ADA accessibility compliance trigger requirements under the Texas Accessibility Standards based on the renovation cost and scope. On Las Colinas office buildings where the original as-built drawings are incomplete, our MEP assessment includes a field survey of the existing ductwork distribution, electrical panel capacity, and plumbing riser locations that will affect the renovation scope.
Step
City of Irving commercial alteration permit submission
Commercial renovation projects in Irving require a building alteration permit, and projects that affect life-safety systems — fire alarm, sprinkler, or exit lighting — require coordination with the City of Irving Fire Marshal's office in addition to the standard building permit review. We prepare the permit submission package with existing building code compliance documentation, including the exceptions and alternative means of compliance provisions that the International Existing Building Code allows for renovation projects that cannot fully meet new construction standards.
Step
Phased construction planning and tenant communication
Phased construction plans for occupied Las Colinas office buildings are developed in coordination with the building owner's property management team and the affected tenants. The phasing plan identifies which floors or zones will be under construction during each phase, what temporary systems will maintain HVAC and electrical service to occupied areas, and what the daily construction start and stop times will be for invasive scope. We provide weekly construction progress updates to the building owner that include a look-ahead schedule showing upcoming disruptive activities so tenants can plan accordingly.
Step
MEP upgrade installation with temporary systems
MEP infrastructure upgrades in occupied Las Colinas office buildings require temporary systems to maintain tenant operations during the transition from the old to the new equipment. HVAC replacement involves portable cooling or heating units or floor-by-floor duct reconnections that maintain conditioned air to occupied spaces while permanent equipment is replaced. Electrical panel upgrades involve temporary power distribution from the building's generator or adjacent panels to maintain circuits serving occupied areas. We coordinate these temporary systems with the MEP engineers and the building owner's facilities team before any permanent system is taken offline.
Step
Punch, inspection, and Certificate of Occupancy closeout
Commercial renovation closeout involves City of Irving Building Inspections final inspection, Fire Marshal acceptance for life-safety system upgrades, and Texas TDLR accessibility inspection for renovation projects that triggered ADA compliance upgrades. We coordinate all three inspection tracks simultaneously to avoid sequential delays. The Certificate of Occupancy or Certificate of Completion is delivered to the building owner along with MEP system commissioning reports, warranty documentation, and as-built drawings reflecting the completed renovation scope.
