IBC Special Inspections

Early Communication is Vital

Determine who will act as the RDP for SI Discuss requirements with the Building Official

Define responsibilities for composition of testing and

inspection requirements (structural, architectural, MP&E)

Determine the format for the Statement of Special

Inspections

Ensure the RFP for SI reflects the required scope.

Establish chain of method and communication for agent

of SI and RDP (design and SI)

75

Special InspectionsF.A.Q.

How do I manage the cost of SI if the contractor isnt

responsible for it?

Because SI and testing is typically provided on a time and materials

basis where the response to RFP only indicates an estimated

maximum cost, this is problematic. Be Active in the Process:

Require preliminary construction schedule to be submitted with

the construction bids (write or review the RFP):

Provide this information in the SI RFP, or better yet

Write the RFP including base service quantities from this schedule.

Enforce construction schedule and approve deviations.

Set up an allowance system for additional SI required f or

Non conforming construction

Deviation from construction schedule

76

Special InspectionsF.A.Q.

Buildings have not been falling down, so why is all ofthis new testing and inspection required?

Construction testing has been required by the model codes and

material standards before the IBC.

Good construction practice has long implemented these, throughthe owner, fabricator, erector, or contractor.

If all of this has been required before, why should yourfee increase now?

While scope of testing is similar, coordination and managementof process has increased. include this in your proposal anddescribe this additional service.
