Expert Witness in Apartment Construction
Empire Projects, Inc., through its principal William N. Bernstein, AIA, has provided expert witness services in matters involving the construction, renovation, and project management of apartment buildings and individual apartment units. Attorneys litigating cases that involve construction defects, scheduling and delay claims, change order disputes, contractor and subcontractor performance issues, project management failures, cost overruns and budget disputes, payment disputes and mechanic’s liens, contract administration and interpretation, means and methods, construction safety, water infiltration and building envelope failures, mechanical/electrical/plumbing system defects, sound transmission and vibration issues between units, fit-out and alteration disputes between sponsors and unit owners or between landlords and tenants, board-approved alteration agreement violations, phased-construction and occupied-renovation problems in tenanted buildings, and other claims related to apartment construction and renovation require an expert witness who understands both the applicable building codes and standards and the practical realities of how apartment construction projects are actually managed, sequenced, and built.
About Apartment Construction
Apartment construction and renovation encompasses a wide range of project types, including new construction of multi-family apartment buildings, ground-up rental and condominium development, gut renovation of existing apartment buildings, building-wide capital improvement projects (facade restoration, roof replacement, elevator modernization, mechanical system upgrades, Local Law 11/FISP compliance work, Local Law 97 emissions retrofits), common-area and lobby renovations, and individual apartment-unit renovations ranging from kitchen and bathroom remodels to full combinations of adjacent apartments. Apartment construction work is performed in occupied buildings as often as not, and the project management challenges of working in occupied residential buildings — noise restrictions, working-hours limitations, dust and debris controls, building protection, elevator and freight access, coordination with building staff, and coordination with neighboring units — are central to the success or failure of these projects.
The construction and renovation of apartment buildings and apartment units is governed by a complex framework of building codes, regulations, and industry standards, including the applicable building code (for example, in New York City, the New York City Building Code), the International Building Code, the International Residential Code where applicable, the International Existing Building Code, ICC A117.1, NFPA 101 Life Safety Code, ADA and Fair Housing Act accessibility requirements, applicable mechanical, electrical, plumbing, fuel gas, and energy codes, local laws addressing facade safety (Local Law 11/FISP in New York City), elevator safety, sprinkler and fire alarm requirements, lead paint and asbestos regulations, and local zoning resolutions and tenant protection rules. In addition, apartment projects are governed by private agreements — proprietary leases and house rules in cooperative buildings, declarations and bylaws in condominiums, leases in rental buildings, alteration agreements imposed by boards or landlords, and the prime contract and subcontracts among the parties to the construction work. Apartment construction projects are also typically subject to insurance requirements, indemnification obligations, and bonding requirements that materially affect how risk is allocated and how disputes are resolved.
Disputes commonly arise over construction defects affecting building envelopes, roofs, terraces, windows, and facades; water infiltration and resulting damage to apartment interiors and neighboring units; mechanical, electrical, and plumbing defects affecting heating, cooling, hot water, and life-safety systems; sound transmission and impact-noise problems between units; scheduling and delay claims arising from owner-caused delays, contractor-caused delays, concurrent delays, and force-majeure events; change order disputes over scope, pricing, and entitlement; contractor and subcontractor performance issues including defective work, abandonment, and improper sequencing; cost overruns and disputes over the basis for cost increases; payment disputes, mechanic’s liens, and lien-law compliance; alteration-agreement violations and disputes between unit owners and boards or between tenants and landlords over the scope and execution of permitted work; construction safety incidents; and disputes arising from phased construction and occupied-building work where building-protection, dust-control, and tenant-coordination requirements were not properly planned or executed. Responsibility for these issues is shared, in different ways, among the owner, the sponsor or developer, the construction manager or general contractor, subcontractors, the design professionals, the building or board (in coop and condo settings), the managing agent, and material and equipment suppliers, and litigation in this area frequently turns on the allocation of responsibility for project management decisions, construction means and methods, and post-occupancy performance.
Expert Witness Services Related to Apartment Construction
Expert witness services in apartment construction matters typically include a careful review of the project documents (drawings, specifications, submittals, RFIs, change orders, schedules and schedule updates, daily reports, meeting minutes, payment applications and supporting schedules of values, permits and sign-offs, alteration agreements, lien waivers, punch lists, certificates of occupancy or temporary certificates of occupancy, commissioning reports, and as-built conditions), a site survey to measure and document the conditions at issue, comparison of those conditions against the applicable building codes, industry standards, contract requirements, and the standard of care applicable to construction project management, review of construction administration and project-management records (correspondence, RFIs, submittals, meeting minutes, daily reports, schedule updates, change order logs, payment applications, and closeout documentation), and the preparation of clear, well-supported opinions regarding the cause of the defect, delay, or failure, the responsibility of the various parties, and the standard of care applicable to the construction, project management, and post-occupancy maintenance of apartment buildings and apartment units.
An effective apartment construction expert witness must be able to explain technical and project-management issues — construction sequencing and scheduling, change order management, contract interpretation, construction means and methods, building envelope and water-management detailing, MEP system design and installation, sound and vibration control, occupied-building protection and tenant coordination, construction safety, code compliance, and the allocation of responsibility among owner, construction manager, general contractor, subcontractors, design professionals, and building management — 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.
