Special Inspector San Diego

Metzger Testing & Inspection provides required special inspections for wind and seismic resistance in accordance with the plans, code and specifications of the City of San Diego. Our independent certified special inspectors provide structural inspection and construction materials testing services. Our engineers, inspectors, technicians observe, document, test and inspect during the process of building construction. The city approved plans from the structural engineer in addition to the contractor’s schedule provide the guidance for testing and inspection. We provide, as needed a CA state professional engineer or special inspector for the monitoring of historical structures and other existing buildings. We can third party monitor the shored structure during adjacent excavations.
A special inspector is a requirement generated by major cities including the City of San Diego which is also known as the City having authority. Special inspection serves the purpose of field inspection and on-site construction materials testing. Special inspection is an additional required third party inspection to the cities mechanical, electrical, plumbing and CA building code inspections.

Special inspections San Diego is best described as a qualified individual having experience and tested by the International Code Council for the area requiring inspections. In San Diego jurisdiction authority is provided for inspections within San Diego county.

The city of San Diego Development Services Department interviews inspectors, reviews their qualifications, verifies education and experience then accepts or denies their request to inspect within the county.

Other incorporated cities within the 4200 square miles of San Diego county recognize the city of San Diego approved special inspector card and will accept the inspector for special inspection within their city after ‘check in’ with the department of development services. Mr. Douglas Metzger is an approved city of San Diego special inspector for the following:

  • Reinforced Concrete
  • Structural Steel and Welding
  • Spray Applied Fireproofing
  • Pre-stressed, Post-tensioned Concrete
  • Structural Masonry

Contractors workmanship is monitored through special inspection periodic or continuous as required by Chapter 17 in the (CBC) California Building Code which is critical to the structural integrity of the building under construction.

Inspectors with the term ‘special’ expertise to inspect the in-progress construction of building materials and connections.

A poorly executed special inspection would be far damaging than having no inspection at all especially if the work shows in compliance.


Reinforcing Steel Inspection

Re-bar are steel bars of various diameters and lengths which have steel ribs that add to the bonding value of concrete for adhesion and additional strength. Reinforcing steel and concrete are bonded together by a mechanical connection.This provides the tensile properties which adds another element of strength to the concrete.


Field Concrete Testing

The testing of concrete at the construction site is to sample the freshly mixed concrete, check for slump, temperature and cast a set of cylinders for compressive strength verification. Slump is a field test to measure water quantity mixed within the concrete. This is mainly for field-use measurement as a guide for the work-ability of concrete.


Post-Tension Concrete

Post-tension concrete cables are long steel cable ropes, usually 1/2″ in diameter within a plastic protective grease coated sheathing. Post-tension concrete cables are a group of cable tendons placed within the concrete providing compression strength laterally. Post-tension concrete cables which are placed within the concrete allows the concrete to be elevated as it has compressive lateral strength.


Field Testing

We perform almost any type of inspection services. Our clients enjoy the quality of our field inspections and structural inspections. Prestressed/Post-Tensioned Concrete, Shotcrete, Structural Masonry, Structural Steel Erection & High Strength Bolting, Structural Steel Visual Welding Inspection, Structural Steel Non-Destructive Evaluation, Spray Applied Fire-Resistive Materials, Lateral Framing (Wood & Cold-Form Steel Structures)


Welding Inspection

Steel is the structural soundness and integrity of the building. If welding is not done by code or procedure it could result in defective work which would lead to the removal of weld areas by grinding and re-welding. As Certified Welding Inspectors Metzger Testing & Inspection can provide guidance to the contractor in producing a welding procedure specification…


Materials Testing

The best field inspection personnel cannot be efficient without excellent support from the laboratory. Metzger Testing & Inspection works with the top laboratory material testing facilities in the area that have quality testing and diagnostic equipment. Concrete and masonry samples, soil, asphalt, fire resistive materials, and many other material types are tested in-house.
