VOC: Stands for Volatile Organic Compounds.
Toxic Materials Discussed:
Arsenic
Cadmium
Dioxin
Furans
Mercury
Bisphenol A (BPA)
Formaldehyde
Lead
Chlorofluorocarbons (CFCs)
Types of Specifications:
Open Specifications: Allow for multiple product options.
Closed Specifications: Specify a single product or brand.
Performance Specifications: Define the desired outcomes or performance standards.
Reference Specifications: Include standards or documents as references.
Bid Process:
Completion of design includes detailed specs, drawings, timelines.
Invitation to multiple bidders.
Project owner, project manager, and designers review bids based on cost, quality, experience, and compliance.
Best bidder is chosen, contract details are negotiated, and monitored until project completion.
CSI: Stands for The Construction Specifications Institute; provides organizational structures for material specifications designed to assist architects and designers by offering a numbered system from broad to specific.
Difference between Type II vs Type III Wallcovering:
Type III is heavier, suitable for healthcare, can endure more cleaning agents, and has a topcoat.
Acoustic Goods Usage: Libraries, churches, and offices benefit from acoustic materials.
Pattern Match Importance: Ensures correct application, saves time and money during installation.
Live Surfaces: Too many can bounce sound, affecting acoustical performance.
Wall Channels: Stop materials from transmitting vibration.
Sound Management Goals: Include providing speech privacy, and creating functional and aesthetically pleasing sonic environments.
Addressing Acoustics by Law: Governed by building regulations, designers must select appropriate materials.
Management Strategies: Use fibrous materials or bumpy surfaces to tackle echo problems, and focus on ceiling and floor covering for airborne sound management.
Paint Formulas:
Water-based vs oil-based; alkyds dry faster, oil paints harder, acrylics provide good adhesion, vinyl acrylics offer breathability.
Skim Coating: Application of a hot mud layer; benefits include a harder surface and better acoustical separation.
Antimicrobial Systems: Used in environments where bacteria or viruses pose health hazards; biocides prevent fungal growth.
Fabric Construction:
Dotted swiss produced by clipping or flocking, cotton dyed before spinning is staple dyed, and twill is particularly durable.
Burn-out fabric is produced by melting fibers; chenille is a common yarn type.
Fabric Finishing Processes: Include calendaring for smoothness, dying for color, and printing for patterns.
Triple Bottom Line: Considers people (ethical labor), planet (environmental impact), and profit (economic viability) in textile selection.
Carpets:
Suitable for residential applications often made from plant fibers; natural fibers include cotton, wool, silk, and exclude nylon.
Denier refers to yarn thickness; placement of seams is critical to minimize visibility.
Cradle-to-Cradle Program: Carpet manufacturers recycle used materials into new carpet.
Law Mandates: Thickness of carpets must meet safety standards when transitioning to thinner floor coverings.
Wood Characteristics:
Figuring creates unique grain patterns; solid wood products have unique properties like CO2 storage and moisture response.
Engineered wood like MDF is suited for doors and paneling due to its performance characteristics.
Chain-of-Custody: Ensures sustainable sourcing, with effectiveness defined by organizations like the FSC.
Millwork Process: Involves bidding, providing shop drawings, and approvals before production begins.
