Since the early 1980s, in an effort to control deadly construction failures, a U.S. subcommittee determined that a major culprit in these failures was improper or insufficient inspections performed by design professionals of record during construction. These inspections cover a variety of project components and have greatly reduced the number of injuries and deaths related to material or construction technique failures.
Special Inspections sometimes referred to as “Chapter 17 Inspections”, are covered by the International Building Code in Chapter 17. These special testing and inspections cover a broad spectrum of a construction project’s components and progress. Special Inspections on a project may include one or several of the following items:
- Structural Masonry
- Verification of Soils including excavation and fill
- Modular Retaining Walls
- Precast Concrete Structures
- Pre-Stressed Concrete
- Reinforced Concrete
- Post Tension Concrete
- Inspection of Precast Fabricators
- Inspection of Structural Steel Fabricators
- Sprayed Fire-Resistant Materials
- Exterior Insulation and Finish System (EIFS)
- Seismic Resistance
- Detention Basins
- Deep Foundations
- Among others
The requirements for special inspections are based on a variety of factors including occupancy class, intended use, project height, seismic categories, as well as wind zones. While the DPIRC (Design Professional in Responsible Charge) typically indicates what inspections are required based on a review of the code, it is ultimately up to the authority having jurisdiction over the project that may require special inspections. The special testing and inspections required by the presiding jurisdiction often cover a variety of project components and often are necessary at various stages of the completion of the construction.
Special Inspection agents are engaged by the project’s owners or for the DPIRC (Design Professional in Responsible Charge) acting as the owner’s agent. A firm performing special testing and inspections do not work for the contractor where the special inspections are required by code, as this would be a conflict of interest.
Special testing and inspections have made a significant impact on the quality and safety of a variety of construction projects across the New York Tri-State region.
