Special Inspections

Special Inspections are defined by the International Building Code (IBC) as the "inspection of construction requiring the expertise of an approved special inspection in order to ensure compliance with the code and the approved construction documents". Special inspection includes both testing and inspection of the materials, installation, fabrication, erection or placement of components and connection to ensure compliance with the code, referenced standards adopted by the code and approved construction documents.

GeoTek focuses on providing special inspection and material testing on a wide range of construction types of projects. GeoTek has staff of highly trained and experienced inspectors who are able to provide a broad range of special inspection services to support any type of construction project, whether it be a simple tenant improvement or a new multi-story building. GeoTek's field staff is accredited and certified by nationally recognized agencies including the Internation Code Council (ICC), American Concrete Institute (ACI), American Welding Society (AWS), and various local agencies. GeoTek became the first in Nevada to be accredited by the International Accreditation Service (IAS). of the ICC to perform special inspections.

Good communication between the special inspector and the designers, contractor and building department is essential to project quality assurance. Using Special Inspections and planning them in advance can significantly improve efficiency, reduce rework, and ensure quality construction. Finding non-conforming items and bringing them to the contractor and developer's attention early is key to avoiding bigger problems later on in the development process.
