Special Inspection Services TR1 TR4 TR8

The city requires building code inspections at various stages of a building’s development. These special inspections need to be provided by certified technicians employed by a registered Special Inspections Agency licensed building inspector. Big Apple is a certified Class 1 SIA that can perform all inspections required by the design professionals and plan examiners.

From foundation inspections to welding inspections, Big Apple conducts controlled inspections for all phases of construction, including the quality control inspections during its progress, necessary for the certification upon final inspection to ensure that all work substantially conforms to the approved construction documents and applicable NYC Building Code provisions. We will confirm that the performance of progress inspections and other inspections has been documented as required.

Report Distribution & Non-Conformance reporting Solutions

As part of Big Apple’s ongoing quest for client satisfaction, we have adopted a few resources which have made us stand out from our competitors. We are proud to have developed solutions to the most common problems relating to the testing and inspection scope of any project; Expedited Report Distribution-Non Conformance Resolution.

Big Apple has incorporated a central data system to streamline construction inspection services linking field inspectors, engineers, project managers, and office personnel into a single information source. This new system works by allowing the inspector to immediately upload his/her report which becomes available to our engineering department instantaneously. At that point, review can begin without delay. Our administrative staff can see when reports have been approved and release them to our the clients immediately. Prior to beginning a project, we set up the database uniquely to your specific chain of command.

Big Apple has dedicated an entire department to optimal Non-conformance Resolution for NYC DOB inspection reports. Unlike our competitors who issue non-conformance reports (NCRs) and leave it up to the client’s team to resolve, our stand reviews project NCR logs daily and assists in facilitating corrective action until compliance is achieved. Big Apple understands who the experts are… us! We will guide all project team members on the most effective ways to adhere to code while considering each project unique challenges. Let us show you how this system has led to a faster construction inspections close-out process.
