WHAT YOU NEED TO KNOW
Low Floor to FLoor Heights with Structural Steel
The Combined Advantages of Structural Steel and Flat Plate Concrete
The GIRDER-SLAB® system offers the same advantages of cast-in-place concrete structures such as low floor to floor heights, but also offers the speed of steel erection and limited impact from bad weather. An added benefit of the system is increased market share for structural steel fabricators. The GIRDER-SLAB® system lends itself to being provided by a single source such as the structural steel fabricator / subcontractor who can budget, fabricate, furnish and install the entire system.
The GIRDER-SLAB® system and D-BEAM® girder are available competitively from steel fabricators authorized by Girder-Slab Technologies, LLC
All materials are procurred from steel local steel fabricators and precast suppliers through a conventional bidding process.
Authorization by GIRDER-SLAB® system is based on a single project commission agreement and project specific quotations will be issued for every job.
Once authorized as a GIRDER-SLAB® system fabricator, you will be entitled to furnish and install the complete system assembly including fabrication and erection of the D-BEAM® girders and installation/grouting of precast concrete slabs.

The open web Dissymmetric Beam shall be fabricated from (ASTM A992/A572 Grade 50) standard steel wide flange sections with flat bar at top-flange and shall meet AISC standards (except for depth, tolerance ± 1/8"), unpainted unless specified. The open web Dissymmetric Beam can be specified to include camber. Cambering can be built in during assembly of the girder.
If the structural engineer of record determines that shoring of the pre-composite assembly is needed, leave in place until grout attains required strength.
Precast prestressed concrete hollow core slab units (min. 5000 PSI) shall be in 4 or 8 foot widths and shall meet PCI standards and tolerances, 2" min. bearing unless specified otherwise.
Reinforcing steel (ASTM A615 Grade 60) shall be placed through the Dissymmetric Beam web openings and into slab cores.
Cementitious grout (min. 4,000 PSI) shall be placed monolithically around and through the Dissymmetric Beam web openings and into slab cores. When concrete topping is used, attain specified strength of grout prior to placement.
The GIRDER-SLAB® system shall be constructed in accordance with Underwriters Laboratories Inc., Floor-Ceiling Assembly Design No. K912 in order to meet fire classification standards and ratings set forth by BOCA and ICC codes.
The GIRDER-SLAB® system and D-BEAM® girders shall be provided by steel fabricators authorized by Girder-Slab Technologies LLC of NJ in conformance with its Design-Guide & Distribution requirements. Steel Fabricator/Distributor contact information: 1-888-478-1100 or www.girder-slab.com.
The supplier of the GIRDER-SLAB® system shall provide to the Project Owner (or its representative) a Girder-Slab Compliance Certificate for each project upon completion of system assembly and construction.

GIRDER-SLAB® system Commission/License
The Girder-Slab Commission/License is determined by project specific requirements and will be provided to steel fabricators through a single project agreement.
For budgeting purposes, steel fabricators should assume a fee of $1.00 per square foot of the total floor and roof area.
Structural Engineers are asked to add the GIRDER-SLAB® system Specification Guide to their General Notes.
Note 7 alerts steel fabricators to contact Girder-Slab Technologies, LLC for authorization and distribution requirements.
