Expert Witness in House Design and Construction
Bernstein & Associates, Architects, through its principal William N. Bernstein, AIA, has provided expert witness services in matters involving the design and construction of houses and related properties. Attorneys litigating cases that involve construction defects, water infiltration and building envelope failures, roof, siding, and window failures, foundation and structural problems, mechanical and electrical system failures, septic and well issues, mold-related claims, builder/contractor disputes over workmanship and contract performance, architect/engineer standard-of-care matters, change order and cost overruns, defects discovered after sale, and other claims related to the design and construction of single-family homes require an expert witness architect who understands both the applicable building codes and standards and the practical realities of how those requirements are applied in the design, construction, and renovation of real houses.
About House Design and Construction
House design and construction encompasses single-family residential building types, including new-construction custom homes, production and tract homes, additions and renovations to existing homes, gut renovations, attached single-family and accessory dwelling units, and the site work and accessory structures associated with them.
The design and construction of houses is governed by a complex framework of technical standards, including the applicable building code (for example, in New York State, the New York State Residential Code), the International Residential Code, the Energy Conservation Construction Code, NFPA 70 (National Electrical Code), local zoning ordinances, applicable wetlands, coastal, and floodplain regulations, and the construction documents and contracts specific to each project.
Disputes commonly arise over construction defects affecting roofs, siding, windows, doors, decks, and foundations; water infiltration through roofs, walls, windows, and below-grade spaces and the resulting damage, including mold; defective framing and structural work; problems with mechanical, electrical, plumbing, septic, and well systems; inadequate or non-compliant work by builders and contractors; disputes over the architect’s or engineer’s standard of care and scope of services; change orders and cost overruns; and latent defects discovered after the sale of a home. Responsibility for compliance with the applicable standards is shared, in different ways, among the owner, the design professional, the builder/general contractor, subcontractors and trades, the home inspector, and the party responsible for ongoing maintenance, and litigation in this area frequently turns on the allocation of responsibility for design decisions, construction means and methods, and post-occupancy maintenance.
Expert Witness Services Related to House Design and Construction
Expert witness services in house design and construction matters typically include a careful review of the project documents (drawings, specifications, submittals, RFIs, change orders, contracts, permits, certificates of occupancy, home-inspection reports, warranty documents, and as-built conditions), a site survey to measure and document the conditions at issue, comparison of those conditions against the applicable residential codes, energy codes, and industry standards of care, review of construction administration records and maintenance histories, and the preparation of clear, well-supported opinions regarding the cause of the defect or failure, the responsibility of the various parties, and the standard of care applicable to the design, construction, and maintenance of single-family homes.
An effective house design and construction expert witness must be able to explain technical requirements — framing and structural detailing, roof and siding installation, window and door flashing, foundation and below-grade waterproofing, residential MEP system design, energy-code compliance, and the standards applicable to residential contractors and home builders — in plain language to judges, juries, arbitrators, and mediators, and must have the credentials, written record, and courtroom-ready communication skills to render credible opinions.
