OVERVIEW

Often referred to as Light Gauge Metal Framing (LGMF), ColdFormed Steel (CFS), Light Gauge Steel (LGS), or Rolled Metal Framing, Light Gauge Steel Construction (LGSC) is a design process unique to BKV Group that is both economic in the form of creative cost reduction, and sustainable by emphasizing industrybased building design:

EASE OF CONSTRUCTIBILITY

• BKV Group employs light gauge steel construction because it uses off-site panelized construction fabrication that lowers on-site labor costs.

• LSGC has net environmental advantages due to the manufacturing processes’ exacting specifications.

• Steel’s material benefits are that it is lightweight, dimensional stable, straight, and has mechanical attachment methods, all resulting in lack of inherent defects.

• With LGSC, you can complete an entire 20,000 SF floor in significantly less time than wood or concrete.

STREAMLINED DESIGN & CONSTRUCTION PROCESS

• LSGC construction adds density at a lower cost per unit while shortening the project duration and lowering labor cost.

• LGSC’s smart grid allows design decisions to be made earlier in the process.

• The LGSC system generates accurate quantity takeoffs and bills of materials, yielding accurate cost estimates early in the design process.

COST-EFFECTIVE DESIGN

The BKV Group design process addresses client cost challenges for higherdensity projects with light gauge steel designs that are high-quality and lower in cost per unit than the traditional wood or concrete approach.

TRANSFER PODIUM & LATERAL DESIGN

For all bearing wall housing designs, the need to have open space for amenity, parking, office, or retail on the lowest levels requires a transfer podium for the bearing wall loads to be transfered to columns.

This is a significant cost over supporting the housing at-grade.

• Multiple design options in systems such as poured concrete, precast concrete, and steel.

• Project location, contractor experience, system delivery, site constraints all affecting selection.

• Concrete is the most flexible. Steel and precast are faster to install.

• Aligning the beams and columns under the bearing walls greatly reduces the cost.

• The lateral design stability is through “X” bracing in the panels or with floor diaphragm to the cores.

COORDINATED RESULTS

BKV Group’s holistic approach involves in-house architects and engineers working in the BIM Revit design platform to coordinate all building systems to create building effectiveness and cost reduction. LGSC is designed to compliment MEP code and assembly of the overall building.

• Holistic, multi-discipline design approach creates coordinated solutions for the modular and prefabricated process.

• The BIM Revit computer modeling of the design confirms the integration of all systems cost effectively.

3. EXCEPTIONAL STRENGTH:

• Steel’s inherent attributes.

• Recognized stability and durability by the U.S. Green Building Council’s (USGBC).

• Decreased maintenance costs and extended life of a building.

4. FABRICATION FLEXIBILITY:

• Can be fabricated to exact specifications to minimize on-site waste.

• Dimensional stability for exceptionally tight building envelope.

• Better building energy performance over time.

5. HEALTHY MATERIALITY:

• Does not emit volatile organic compounds (VOCs).

• Better indoor air quality.

• Meets the solar reflectance and LEEDv4 requirements.

• Reduced cooling loads and lower utility bills.

STABILITY OF SUPPLY & MANUFACTURING

• Steel prices are more stable due to the high-recycled content.

• Panelized system suppliers are numerous and will deliver panels up to 500 miles to project.

• Thinner gauge, “hot-rolled” structural steel is simpler to create.

• Present supply of scrap steel keeps prices stable.

• More cost-effective than lumber and concrete on a per unit basis.

RESILIENT CHARACTERISTICS

1. PROTECTION AGAINST SEISMIC FORCES:

• Safe, noncombustible framing system achieves the desired overall building height.

• Higher strength-to-weight ratio at one third the weight of the same wood framed structure.

• Less weight and less inertia (less weight to stop moving).

• Mechanical means of connecting members which cannot be easily undermined.

• Maintains its structural integrity for its entire life-cycle.

• Tighter, more uniform structure resist earthquakes.

2. MITIGATING SPREAD OF FIRE:

• Will not contribute to the spread or intensity of a fire.

• A better loss history than wood-framing members.

• Does not add fuel-to-the-fire as does conventional framing lumber.

• Fire is contained at the point of origin and denied the opportunity to spread.

3. MITIGATING SOUND:

• Measurable decrease in STC values in light gauge steel construction.

• Tighter construction provides greater sound reduction.
