NYC Special inspections

​​​​​​Special inspectors are third party licensed professional engineers who oversee the construction and materials testing to sign off on your project. Special inspection agencies are required to be hired by the owner, and are required for every single permitted project in New York City.  We provide all levels of special inspection services from concrete to fit out including structural steel, welding, concrete, masonry, and spray fireproofing, mechanical, energy, sprinkler, and firestopping. Our team includes special inspectors for:















The inspectors are multidimensional therefore maximizing the skills and abilities of each inspector and pass significant savings to our clients. For example, we use mechanical inspectors that are also certified in energy, plumbing, sprinklers, and fire/life safety since they are closely related to mechanical system installation.


Our Engineering Services have received special inspection accreditation from International Accreditation Service (IAS).
