Re: Structural Steel Special Inspection Procedural and Final Report
Twin Oaks Middle School
15860 Fish Pond Road SE
Prior Lake, Minnesota
Dear Mr. Svendsen:
Please find attached to this procedural report the Structural Steel Special Inspection Final Report for the
Twin Oaks Middle School Project and the supporting Special Inspection Daily Reports.
Special Inspection and Testing Procedures
The special inspection services were periodically provided by International Code Council (ICC) certified
special inspectors in accordance with the requirements of the Minnesota State Building Code,
Chapter 17 of the International Building Code (IBC) and the project plans and specifications.
The purpose of special inspections is to provide a review of the contractor's work designated by the
project structural engineer as needing special inspection under the guidelines of the IBC to determine
compliance with the approved construction documents. The special inspector does not have the
responsibility or authority to, nor is it the intent of special inspections to have them,judge or modify
the construction documents. Only the structural engineer of record can do this.
As the special inspections were completed,a Special Inspection Daily Report was prepared to summarize
the results of our inspections and testing. A copy of this report was provided to the contractor's site
representative for their review and records. As part of this report, items needing correction or
discrepancies observed from the approved construction documents were noted. As needed, we also
contacted the project structural engineer for additional clarification on specific issues related to the
drawings or discrepancies observed.
Plans and Specifications
The plans and project documents available at the site were used for our inspections. From time to time,
we received plan modifications from the structural engineer. When received, these were used to
evaluate the work completed in the field.
Visual Examination of the Field-Made Welds
Visual examination of the field welds was conducted in accordance with American Welding Society
(AWS) D1.1-2010, Figure 5.4 and Table 6.1 requirements and the requirements of the project plans and
specifications.

Tension-Control Bolted Connection Observations
Tension-control bolted connection observations were conducted to determine if the bolt holes were
filled, if the correct bolts were used, if the nuts were fully engaged and if the splined end of the tension-
control bolts had separated from the body of the bolt. Removal of the splined end is a direct indicator
the bolt has been torqued to the minimum snap-off load. At connections where the splined ends were
not, or could not be removed,the torque applied to the bolt by the contractor was determined using a
hand-held torque wrench. In addition, each connection was observed for fit-up and to determine if the
various plies were in contact with one another.
Drilled-In Epoxy Anchors
Observations were performed during the installation of the drilled-in epoxy anchors to determine if they
were installed according to the requirements of the manufacturer and the project documents. Items
observed included the placement, depth of embedment, cleanliness of the drilled hole and application of
the epoxy adhesive. The type of epoxy used was also documented for compliance with the
requirements of the specifications. As part of these observations, we documented that the adjoining
plies were in contact with one another and that the nuts were fully engaged and snug tight.
General
In performing its services, Braun Intertec used that level of care and skill ordinarily exercised by
reputable members of its profession currently practicing in the same locality. No warranty, express
or implied, is made.
Thank you for the opportunity to provide the special inspection and testing services for this project.
After review of the attached Special Inspection Final Report, if you have any questions or require
additional information, please call Dan Graham at 952.995.2524 or Mary Denne at 952.995.2510.
