Permit#: BUP2015-00034
Per Chapter 17, Section 1704.1.2 of the International Building Code(IBC), we have performed special inspection of the
following item(s) per our inspection reports only:
Reinforced Concrete
Cast-In-Place Anchors&Adhesive Anchors
Structural Steel
The non-compliance (NC) items recorded for each of the above inspection categories, as listed on the non-compliance
report, have been either repaired and re-inspected by CTI for compliance or reviewed and accepted by the engineer of
record for the project in the"As-Built Condition"or through an RFI.
The issuance of this final report is based on the engineer's acceptance of the NC items not specifically re-inspected by
CTI. CTI did not provide any additional review or re-inspection of those items beyond the inspections that initially
generated each of these individual items on the non-compliance list. The engineer of record has provided the acceptance
of the non-compliance items and as-built conditions.
All requested inspections and tests were performed and reported according to the requirements of project documents and
to the best of our knowledge, the work was in conformance with the approved plans and specifications, approved change
orders and applicable workmanship, provisions of the State Building Code and Standards, as well as the structural
engineer's design changes, approvals and verbal instructions.
Our construction inspection and testing services were provided and intended to help reduce the risk of construction
defects, deficiencies or omissions that arose during and after construction. Our services do not constitute a warranty or
guarantee of any type. Even with diligent construction monitoring and testing, construction defects, deficiencies or
omissions in the contractor's work may exist. It is the contractor's responsibility to perform their work in accordance with
the approved construction documents.
CTI has provided its professional services with the degree of care and skill currently exercised under similar
circumstances by members of its profession in the same locale. Statements made in our reports are based on technical
judgments and should not be construed to be conclusive representations of fact. Our reports pertain to the material
tested/inspected only.
