This template reflects the minimum IBC2012 required inspections and frequency of
inspection.
This document is intended to be tailored by the Designer of Record (DOR) to accurately
reflect project specific special inspections.
Tailoring the Schedule of Special Inspection involves the following
Deleting pages of the table for work that is clearly not part of a project. For example,
Masonry Special Inspection Tables should be deleted for a project that does not contain
any masonry work.
Selecting the check box in the first column for those items on each table that will
require the special inspection for the project.
Examining the project for highly critical items that may warrant adding additional
special inspections beyond the IBC minimum or more frequent inspections of more
critical items. For Design-Bid-Build project, discuss potential additional inspection with
the Government Design Manager to determine if additional inspections should be
included.
DOR is not authorized to delete or reduce the frequency of Special Inspections, where work
requiring those inspections is clearly part of the project.
Items identified with (AISC 341) in the task column are required only where the project is
designed per AISC 341 – Seismic Provisions for Structural Steel Buildings.
* - indicates Special Inspections required for wind resistance in the following areas:
In wind Exposure Category B, where Vasd is 120 miles per hour or greater.
In wind Exposure Category C or D, where Vasd is 110 miles per hour or greater.
** -indicates Special Inspections required for seismic resistance in the following areas:
Seismic force-resisting systems in structures assigned to Seismic Design Category C, D, E
or F.
Designated seismic systems in structures assigned to Seismic Design Category C, D, E or
F.
Mechanical and electrical components in structures assigned to Seismic Design
Category C, D, E or F.
Electrical components not part of emergency or standby power systems in structures
assigned to Seismic Design Category E or F.
Storage racks in structures assigned to Seismic Design Category D, E or F.
*** - indicates documentation only required for projects designed under AISC 341. For
projects only designed under AISC 360, remove “D” designation.
# - indicates Special Inspections required for progressive collapse resistance.
Hidden text indicates where each inspection item is located in the building codes.

P – Perform these Special Inspections tasks for each welded joint or member. (AISC 360 & AISC 341)
O – Observe these Special Inspections items on a random daily basis. Operations need not be delayed
pending these inspections. (AISC 360 & AISC 341)
D – Document, with a report, that the work has been performed in accordance with the contract

C – Continuous Special Inspections is the constant monitoring of specific tasks by a special inspector. These
inspections must be carried out continuously over the duration of the particular tasks. (IBC)
P – Periodic Special Inspections is Special Inspections by the special inspector who is intermittently present
where the work to be inspected has been or is being performed. (IBC)
