Property Condition Assessments
Our Property Evaluation Reports exceed ASTM standards through detailed plan reviews, visual inspections by licensed professionals, and 10-year cost projections. We analyze building systems, interview property staff, and document maintenance history to identify immediate and long-term ownership costs. Peer-reviewed reports include code compliance assessments and ADA barrier removal planning.
Construction Oversight
We review construction documents, budgets, and site work to prevent cost overruns and delays. Our team identifies plan errors, verifies code compliance, and provides real-time issue resolution using PlanGrid technology. Monthly field reports track progress against schedules and budgets while final closeout reports certify substantial completion of projects.
Energy Audits
ASHRAE-certified auditors analyze utility data and building systems to identify energy-saving opportunities. We evaluate HVAC, lighting, and water systems while providing actionable roadmaps for reducing consumption. Our audits combine historical billing analysis with on-site inspections and staff interviews to deliver data-driven efficiency recommendations.
Forensic Architecture
We investigate unexpected building system failures using non-invasive methods and selective destructive testing. Our experts diagnose issues with roofing, structural components, waterproofing, and mechanical systems. Detailed reports include repair recommendations with cost evaluations to restore property performance and value.
Capital Replacement
We manage full-cycle capital replacement projects from design development to construction monitoring. Our services cover pavement, roofing, exterior walls, and mechanical systems. We assist with contractor selection, permit acquisition, and budget management while ensuring work aligns with approved plans and specifications.
