§ 155.168 INSPECTIONS.
   (A)   Requirement. All construction or work for which a permit is required shall be subject to inspection by the Building Inspector and certain types of construction shall have continuous inspection by special inspectors. A survey of the lot may be required by the Building Inspector to verify compliance of the structure with approved plans.
   (B)   Inspection record card. Work requiring a building permit shall not be commenced until the permit holder or his agent shall have posted an inspection record card in a conspicuous place on the front premises and in such position as to allow the Building Inspector conveniently to make the required entries thereon regarding the inspection of the work. This card shall be maintained in such position by the permit holder until the certificate of occupancy has been issued.
   (C)   Approvals required. No work shall be done on any part of the building or structure beyond the point indicated in each successive inspection without first obtaining the written approval of the Building Inspector. Such written approval shall be given only after an inspection shall have been made of each successive step in the construction as indicated by each of the inspections required. There shall be a final inspection and approval on all buildings when completed and ready for occupancy.
   (D)   Called inspections. No reinforcing steel or structural framework of any part of any building or structure shall be covered or concealed in any manner without first obtaining the approval of the Building Inspector. The Building Inspector, upon notification from the permit holder or his agent, shall make the following inspections of Type V buildings and shall either approve that portion of the construction as completed or shall notify the permit holder or his agent wherein the same fails to comply with the law.
      (1)   Foundation inspection shall be made after trenches are excavated and forms erected and when all materials for the foundation are delivered on the job. When concrete from central mixing plant (commonly termed "transit mixed") is to be used, materials need not be on the job.
      (2)   Frame inspection shall be made after the roof, all framing, fire-blocking, and bracing are in place and all pipes, chimneys, and vents are complete.
      (3)   Lath and/or wallboard inspection shall be made after all lathing and/or wallboard, interior and exterior, is in place and all plastering materials are delivered on the job, but before any plastering is applied or before wallboard joints and fasteners are taped and finished.
      (4)   Final inspection shall be made after building is completed and ready for occupancy.
   (E)   Other inspections. In addition to the called inspections specified above, the Building Inspector may make or require any other inspections of any construction work to ascertain compliance with the provisions of the SBC and other laws. For the purpose of determining compliance the Building Inspector may cause any structure to be reinspected.
   (F)   Special inspections.
      (1)   In addition to the inspections otherwise required, the owner or his agent shall employ a special inspector who shall be present at all times during construction on the following types of work:
         (a)   On concrete work when the design is based-on an "f'c" in excess of 2,000 pounds.
         (b)   On masonry work when required.
         (c)   On all structural welding.
         (d)   On all cast-in-place reinforced gypsum concrete when it is being mixed or deposited.
      (2)   On special construction or work involving unusual hazards or requiring constant inspection there shall be a special inspector. The Building Inspector may waive the requirement for the employment of a special inspector if he finds that the construction or work is such that no unusual hazard exists.
      (3)   The special inspector shall be a qualified person approved by the Building Inspector. The special inspector shall furnish continuous inspection on the construction and work requiring his employment. He shall report to the Building Inspector in writing, noting all SBC violations and other information as required of him.
      (4)   Special inspections shall not be required where the work is done on the premises of a baricator approved by the Building Inspector to perform such work without special inspection. The certificate of approval shall be subject to revocation by the Building Inspector if it is found that any work done pursuant to the approval is in violation of the SBC.
