Structural Steel

This guideline is based upon the scope of work for primary structural steel framing.  If the scope of work does not entail primary structural steel framing, then AISC certification may not be required, however, final determination would be at the discretion of the Project Manager and/or the UM AHJ.  Project scope that includes any of the following listed criteria would not require AISC certification.

  • Lintels
  • Structural steel for door frames
  • Unistrut installations for patient lifts, etc.
  • Equipment supports
  • Seismic bracing
  • Handrails (further requirements covered under miscellaneous metals section)
  1. Qualifications: Submit for record qualification data, (personnel and firm resumes, and project lists with references), for the Structural Steel Fabricator, (Fabricator), Structural Steel Detailer, (Detailer), Contractor’s Engineer(s) and Structural Steel Erector, (Erector).
  2. Shop drawings shall be prepared by AISC Certified fabricator.
  3. The Fabricator shall have five (5) years of comparable experience in installations of this type and shall employ labor and supervisory personnel familiar with the type of installation, experienced in fabrication and erection of structural steel for projects of familiar size and complexity. At the time of bid the Fabricator shall be AISC Certified to the Standard for Steel Building Structures (BU) and must submit proof of these qualifications. The Fabricator’s qualifications shall be subject to review by the Design Professionals and Owner.
  4. The Detailer shall have five (5) years’ experience preparing detailed steel shop drawings and CNC downloads for structures of this type and complexity. The detailer’s qualifications shall be subject to review by the Design Professionals and Owner. All detailing shall be performed with 3D modeling software, such as TEKLA STRUCTURES, SDS-II or equivalent. Model shall be maintained to be current throughout the construction and in a form usable by the Design Professionals.
  5. The Contractor’s Engineer(s) shall be qualified to perform the type of work required by the project. The Engineer shall be a Professional Engineer licensed in both the state where the project is located as well as the state of Missouri. The Contractor’s Engineer(s) shall have five (5) years of experience being in responsible charge of work of this nature. The proposed Engineer(s) shall be subject to approval of Design Professionals and Owner.
  6. The Erector shall have five (5) years of successful experience erecting structural steel for structures of this type and complexity. At the time of bid the Erector shall be an AISC Certified Steel Erector (CSE) and must submit documentation of this qualification.
  7. Certified Welders, (shop, tackers and field) shall be certified in accordance with AWS D1.1 and shall remain in effect for the duration of the work and/or while they are continuously engaged in performing this type of work for which they are certified as determined by the Testing Agency. Certification and re-certification of welding personnel is subject to verification by the Testing Agency. Re-testing for re-certification will be the contractor’s responsibility.

 Testing

  1. Consultant will specify inspection and testing requirements and will include procedures for evaluation of test data. The University will retain the services of an independent testing firm to test all steel connections. Contractor will be responsible for scheduling tests. Contractor will be responsible for scheduling tests. Contractor will be required to notify the Owner’s representative a minimum of 48 hours prior to the time testing is needed.
  2. Test results will be specified to be sent directly to the contractor, architect and the Owner’s representative.

Other Requirements:

  1. Consultants should consider use of twist-off Lejeune bolts and load indicator washers for field structural connections.
  2. Pre-engineered metal building roof purlins will be adequately braced on the compression flange to resist all design loads. Purlin slide clips commonly used with standing seam systems will not be considered an effective brace for the purlin. Separate purlin bracing such as threaded rods or sag angles must be provided in addition to the slide clips.

Cold Formed Steel:

  1. Consultants will design to AISI standards at a minimum. All assemblies will be fully detailed by the design team, including specifying gauges, layouts, connections, and sizes of the materials to be used. NO Delegated Design is allowed for this scope of work.

Miscellaneous Metals:

  1. At exterior guardrails and handrails that are not a significant part of the building’s architecture, construction will consist of fully welded hot dipped galvanized steel pipe. Infill panels will consist of vertical balusters. Support posts will be set in sleeves oversized 1” and cast into the walk.
  2. On MU projects: railings will be commercial grade aluminum or stainless-steel pipe rail. Support post connections/mounting to stairs and walkways will be by the way of mechanical fasteners and surface connection. Verify the mounting details with the PM. (core vs. sleeve vs. surface mount with anchor).
  3. Specifications will require a mockup panel for all welded railings, grilles, and similar architectural metal panels.
