- 2. • Raw polystyrene beads are molded into one of two basic forms. • Block systems simply stack and interlock-almost like big Lego’s. • Panel systems are held a constant distance apart by a series of plastic ties. Today there are more than 70 manufacturers of Insulating Concrete Forms. Buyer Beware!!!

- 5. CONCRETE HISTORY Frank Lloyd Wright – • “My buildings will last at least 300 years!” • Began using concrete as early as 1889. • Concrete is “so flexible and simple as to be almost unbelievable.”
- 6. CONCRETE HISTORY Thomas Edison – • Believed that “concrete was the material that would revolutionize housing”. • Felt concrete would build cost effective homes. • In 1908, he built 11 homes similar to this model.

- 50. Savings Summary: • Insurance discounts as high as 25%. on-going savings for the life of the home. • Energy consumption savings of 44% for heating, and 32% for cooling. This can add up to huge lifetime savings! • Labor hours are drastically reduced. The material is extremely lightweight, requiring less effort to lift, move, place or cut. Eliminates other building steps.
- 51. Single Family Residential Summary: • Home Buyers have Wants and Objectives • With ICF, Builders can satisfy Buyers Wants. • ICF Homes EXCEED Expectations and can translate to higher profits for builders and savings for the owners.
- 52. Commercial/Multifamily Residential • Energy Savings • Fire Ratings • Structural Envelope • Building Flexibility • Code Approvals • Compatibility with Commercial Designs • Speed
- 53. Demand for durability and energy performance is growing. ICF technology is a proven building system. When compared with other building materials, concrete is a responsible, wise choice for sustainable development.

- 62. Hard pavement collects runoff and sends it downstream. Concentrated Runoff is created. Pervious pavement keeps rainfall on site by Infiltration & Dispersion No Runoff is created.
- 63. Pervious Concrete creates A Micro-ecosystem Water-held by capillary tension Oil & Hydrocarbons held & Digested by microbes Oil does not come out the bottom HUGE surface area

Water Filtration Pollutant Removal of Pervious Pavement (%) Pollutant Pollutant Removal Total Suspended Solids 95% Total Phosphorous 65% Total Nitrogen 82% Nitrous Oxides N/A Metals 98-99% Bacteria N/A http://www.stormwatercenter.net/Assorted%20Fact%20Sheets/Tool6_Stormwater_Practices/Infiltration%20Practice/Porous%20Pavement.htm
- 67. Pervious is ADA Friendly
- 68. Designing & Specifying A Pervious Concrete Pavement Structure • ACI 5221-08 • Define loading condition • Assess soil support value • Select thickness based on flexural strength (MR=375 psi) • Check against overweight loading – ½” thickness increase can increase strength and life expectancy by 33% to 50%
- 69. Storage Capacity Storage capacity typically governs design Depends on porosity of pervious pavement and subbase 1” of pavement with 15% porosity can store 0.15” 1” of #67 stone base with 40% porosity can store 0.40” 4” pavement on 6” subbase can store 3” of rain Porosity depends on level of compaction Pre-construction test to establish porosity vs. unit weight
