At Z&T Engineering PC, we provide a comprehensive suite of structural engineering services tailored to meet the unique needs of projects in New York City and Long Island. From designing new structures to ensuring code compliance and safety, our expertise spans residential, commercial, and industrial sectors. Discover how our solutions can support your project from start to finish.
Designing a new building's structure starts with conceptual design, developing initial concepts based on architectural plans. Engineers perform load analysis to determine the various loads the building will face. Structural analysis involves using computer simulations to predict responses to these loads and selecting appropriate materials. System design focuses on the main structural elements, ensuring stability. Element detailing creates precise specifications for each component. The iterative design phase refines the plans until final drafts are ready. During construction administration, engineers oversee the build to ensure compliance, concluding with quality control through regular inspections. This process ensures safety and compliance with all standards.
Retrofitting an existing building involves structural upgrades to enhance safety and performance. The process begins with a thorough assessment to identify areas needing improvement. Goals, budget, and timeline are defined. Structural enhancements, such as reinforcing beams and columns, are planned. Necessary permits and approvals are obtained from local authorities. The construction work is then carried out, with regular inspections to ensure quality and adherence to design specifications. This process improves the building's safety, stability, and extends its lifespan, ensuring it meets modern standards and requirements.
Designing foundations and support of excavation (SOE) ensures stability and safety during construction. The foundation supports the building’s load, transferring it to the ground. Types include shallow (spread footings, mat foundations) and deep (piles, caissons), chosen based on geotechnical surveys. SOE provides temporary support to prevent soil collapse, using methods like shoring, underpinning, and bracing. Engineers design these systems based on excavation depth, soil conditions, and adjacent structures. This ensures the building remains secure throughout the construction process, meeting modern standards and requirements.
The NYC DOB Energy Code TR8 Audit involves progress inspections to ensure compliance with the New York City Energy Conservation Code during construction. The TR8 form, or Technical Report Statement of Responsibility, is used by certified inspectors to certify that all required inspections have been completed and that the construction meets the approved plans1. This includes verifying insulation, fenestration, air barriers, HVAC systems, and other energy-related components.
We conduct facade inspections to ensure compliance with NYC Local Law 11, helping property owners maintain safe and visually appealing building exteriors.
Our inspections ensure parking structures meet the safety standards set forth in NYC Local Law 126, preventing potential hazards and ensuring compliance.
Site safety design involves creating a plan to ensure the safety of personnel and equipment on a construction site. It includes identifying hazards, establishing safety protocols, providing safety training, and developing emergency plans. Proper use of personal protective equipment (PPE) is crucial. Effective site safety design minimizes accidents, enhances productivity, and maintains a safe working environment throughout the construction process, ensuring compliance with local regulations and standards.
A Pre-Construction Survey involves a detailed inspection of a property's existing conditions before construction begins on an adjacent site. This survey identifies any signs of exterior and interior damage, as well as structural settlement. The goal is to document the current state of the property, providing a baseline for comparison during and after construction. This helps protect property owners and developers from disputes over construction-related damage.
A Tenant Protection Plan (TPP) outlines steps contractors and building owners take to protect tenants during construction or renovation. It aims to minimize disruptions and negative impacts on tenants. Key elements include maintaining egress and fire safety, controlling dust and debris, ensuring health standards, and providing essential services like heat and water. The TPP must be approved before construction permits are issued and is tailored to each project's scope.
A Preliminary Commissioning Report (PCR) is a document prepared by a commissioning agent to outline the commissioning process for a building's systems, such as HVAC, electrical, and plumbing. The PCR includes the commissioning plan, schedule, and the qualifications of the commissioning team. It ensures that all systems are designed, installed, and tested to meet the owner's operational requirements and performance criteria. The PCR is submitted to the NYC Department of Buildings (DOB) for review and approval before the mechanical sign-off.
A forensic investigation in construction involves a thorough examination to identify and analyze defects, failures, or issues within a building or structure. This process includes gathering evidence, such as photographs, videos, and measurements, to determine the cause of problems like water intrusion, structural cracks, mold, or code violations. The findings help in resolving disputes, guiding repairs, and ensuring compliance with building standards. Certified forensic investigators use their expertise to provide detailed reports and expert testimony if needed.
An Engineer Peer Review is an independent evaluation of engineering designs, plans, or projects by a team of qualified professionals. The goal is to identify and correct defects early in the development process, ensuring the project meets all standards and requirements. Peer reviews improve project quality, enhance communication among team members, and reduce the risk of errors. They are distinct from management reviews and audits, focusing solely on technical aspects.

Construction management is a professional service that ensures a construction project is completed on time, within budget, and to the desired quality standards. It involves planning, coordinating, and overseeing the entire construction process from start to finish. Key responsibilities include managing the project's schedule, cost, quality, safety, scope, and function. Construction managers work closely with owners, architects, engineers, and contractors to ensure successful project delivery.
Shop drawings are detailed technical drawings used in construction to illustrate how specific parts of a project should be fabricated, assembled, or installed. They provide precise measurements, materials, and installation instructions for components like structural steel, HVAC systems, and windows. Shop drawings ensure that every detail aligns with the overall design, facilitating clear communication between designers, fabricators, and installers.
The TR1 and TR8 forms are used in NYC for ensuring compliance with building codes during construction. TR1 covers special inspections, ensuring that specific elements like structural components, mechanical systems, and insulation comply with building codes. TR8 focuses on progress inspections for energy code compliance, verifying elements like insulation placement, air barriers, and HVAC systems. Certified inspectors complete these forms to certify that all required inspections have been carried out according to the approved plans. This process ensures the safety, efficiency, and code compliance of the building throughout the construction phase.
MEP design, which stands for Mechanical, Electrical, and Plumbing design, is a crucial aspect of building construction. It involves planning and detailing the systems that ensure a building's comfort, functionality, and safety. Mechanical systems include heating, ventilation, and air conditioning (HVAC) to maintain indoor temperature and air quality. Electrical systems cover power distribution, lighting, and communication networks. Plumbing systems manage water supply, drainage, and waste disposal.
