G i r d e r - S l a bT M SYSTEM APPLICAT I O N

The Gird e r-Slab System in combination with a structural steel

frame offers a complete steel and concrete superstructure.

It is slated for use in mid to high-rise residential structures such

as hotels, apartments and condominiums. There are two basic

D-Beam Girder sections available for use with an 8” thick

p recast slab. The DB-8 provides an 8” thick slab

a s s e m b l y, while the DB-9 is designed for use with 2”

c o n c rete topping resulting in a 10” thick slab. Precast slabs

generally span as long as 28’-0”. The Gird e r-Slab System is

rated for use in high-rise buildings when constructed in

a c c o rdance with Underwriters Laboratories Inc. Floor- C e i l i n g

Design K912. The Gird e r-Slab System greatly improves

construction operations and the ability to meet critical deadlines.

G i r d e r - S l a bT M SYSTEM TECHNOLO GY

This patented, A s s e m b l e d - I n - P l a c e technology is the first

ever to use precast slabs with an integral steel girder to form

a monolithic structural slab assembly. The Gird e r- S l a bT M

System consists of an interior girder (known as an open-web

dissymmetric beam or D- B e a mT M) supporting precast

p re s t ressed hollow core slabs on its bottom flange. Upon

g routing, the Gird e r-Slab System develops composite action

enabling it to support residential live loads. Grouting is

easily achieved after slabs are set in place. The Gird e r- S l a b

System affords users advantages never before available

with cast-in-place concrete superstructures. It is lightweight

and offers rapid construction and assembly.

The underside of slab is free of supportbeams providing a flat surface for ducts andpiping systems. Minimum ceiling heights at8’-0” are easily attained.

Allows faster access for the work ofother trades. Coring of slabs for utilitiesis easier and permits final adjustment.

The innovative D-Beam Girder was designed to allow theprecast slab to set on its bottom flange concealing its topflange and web. No formwork or scaffolding is needed.

For the first time ever, a newsteel and PRECAST concreteF RAMING system that gives yo ulow flo o r -t o - f loor height.

The grouting process is easily performed with a fewtradesmen. The cement grout is liquefied and pumpedthrough a hose. Workers puddle the grout in order tofill in the voids and slab cores.

Unlike cast-in-placeconcrete structures, theGirder-Slab System isAssembled-In-Place.

The underside of slab isready made for ceiling finish.

A sample D-Beam™ Girder used for testing is fullyencapsulated by hardened grout.

Precast slabs readily drop in place. The D-Beam Girderself centers each slab.

The Gird e r-Slab System was used in this seven story studenthousing project for a prestigious Philadelphia university.

G i r d e r - S l a bT M SYSTEM BENEFITS

■ Min. floor-to-floor heights, maximize building height

■ Super-fast structure and building completion

■ Reduced building structure weight

■ Floor plan design flexibility

■ Limited weather impact (including cold climates)

■ Structure assembly is one process, one source

■ Integrates well with mixed use spaces below

■ Meets AISC tolerance standards

■ Meets fire code ratings using UL K912

■ Meets required sound (STC) ratings

■ Limited on-site labor

■ Reduced on-site overhead costs

■ Eliminates/reduces soffits

■ Factory made quality components

After slabs are set, grout is easily placedflowing around the D-Beam and through itstrapezoidal shape web openings and intothe slab cores.

After grouting, the slab is completeand ready for use. Finish floorpreparation work can take placebefore or after interior walls.

Precast slabs can be set in placein nearly any climate conditionincluding freezing temperatures.

In the course of history, few breakthrough ideas or innovations have come by design; more often thannot they are usually the result of happenstance, lucky coincidence. The trio who developed theGirder-Slab System did it thanks to their persistent belief that a real alternative to cast-in-place

concrete, residential superstructures was possible. It took the convergence of three separate, yetintertwined, types of expertise - a builder, a structural engineer and a steel contractor - to break the“cast concrete” paradigm and to emerge with a revolutionary approach.

Based upon early ideas founded around 1990, John Costanza the builder, Pete Naccarato thestructural engineer and Dan Fisher the steel contractor embarked on a series of meetings to developthe concept. After securing their first U.S. patent for the system, the trio developed a significant break-through, not only to improve its design, but to provide a more efficient method of making the D-BeamGirder. The improved D-Beam Girder offered a more cohesive solution to the composite system aswell as efficiency of production. The Girder-Slab System, with U.S. patents and international patentspending, featuring the open web D-Beam Girder, employs a sophisticated technique to split a standardrolled, wide-flange section in order to produce two D-Beam Girders. The byproduct of this commonlyused technique creates web openings with no waste.

The story is really more of an account of three men connected by both personal and profes-sional respect for one another. Giving birth to new ideas is often taxing, requiring great patience. Eachpartner had to ensure that the final system met his own personal and professional criteria. As a result,we introduce the Girder-Slab System, after many years of rigorous review, testing and use. Thefuture of the system holds many opportunities for the industry, given the emergence of trends towardsdesign-build, less on-site skilled labor, single sourcing, pre-engineered/pre-fabricated components and,of course, ever-present deadline demands.

The founding partners, John Costanza,Pete Naccarato and Dan Fisher, nurtured and developed the Girder-SlabSystem over the past 10 years.
