FLOOD PANEL™ FLOODPROOFING TRAINING PROGRAM PART 1: DRY FLOODPROOFING SYSTEMS COURSE# 14003 © Flood Panel 2014 April 28, 2014
ABOUT THE PROGRAM: • Due to the ever growing threat of flooding across America and the Federal government removing subsidies for the National Flood Insurance Program, there are incentives for commercial building owners to install dry flood proofing mechanisms that mitigate the impacts from flooding. • Flood Panel, LLC designs, sources, installs and maintains high-quality flood protection products on commercial construction projects. The aluminum Flood Panel are flood barriers that will last for the life of the buildings if properly installed and maintained. • An elite team of expert architects, engineers and contractors have been identified, by Flood Panel, LLC, to train industry professionals on the installation and deployment of their vast array of flood protection products. The training is relevant to structural engineers, architects, shell contractors, construction professionals and commercial building owners. • The nation’s vulnerability to flooding is increasing. Because new insurance policies and the modernization of FEMA’s flood maps affecting property insurance and insurability, there is a great demand for Flood Panel products to be installed at commercial properties. 2

FOCUS: COMMERCIAL BUILDINGS IN THE 100 YEAR FLOOD ZONE Today’s Program Outline • Is flood risk a problem for your clients? • Estimate the risks’ frequency and magnitude • Alternatives Solutions to address the problem – System Designs – Implementation – Operation and maintenance • Factors in System Selection • Design Process • Load Calculations 1 Flood Zones, Codes, Insurance 2 Assessing Risk 3 Alternatives 4 Functional specifications 5 Dry Floodproofing Systems 6 System Design 4
SESSION 5: SELECTION AND DESIGN OF DRY FLOODPROOFING SYSTEMS 5
LEARNING OBJECTIVES: • Learn to select and design dry floodproofing systems • How to conduct field investigations • Learn structural failure mechanisms that occur in flood conditions • Learn dry floodproofing system elements 6
SELECTION AND DESIGN PROCESS FOR DRY FLOODPROOFING SYSTEMS 1. 2. 3. 4. 5. 6. 7. Field Investigation Confirm structural capacity of building Select sealants and shields Design drainage collection systems Design backflow valves Design emergency power needs Prepare emergency and maintenance plans 7
FIELD INVESTIGATION • • Low Point of Entry Survey Structural reconnaissance Soil type Flood warning time Flood duration (power outage) Utilities locations Information for building weight calculations Adjacent buildings 8

FLOOD SHIELD SOURCES Manufacturers • Flood Panel • PS Doors • Pres. Ray No one does “Do It Yourself” twice. Do It Yourself 1. Determine flood and flood-related loads* 2. Select plate material 3. Determine panel stresses 4. Calculate deflections 5. Design plate connections 6. Select gasket or waterproofing 7. Check adjacent walls, lintels, sill and top/bottom connections 8. Prepare details and specifications 9. Manufacture 10. Test *Separate training course 17
SELECTION OF FLOOD PANELS Manufactured panels: 1. Determine height of flood protection 2. 3. Measure span width of protection required Determine condition at location of connection to the building (solid concrete, brick, veneer, cladding, etc. ) Determine connection based on conditions at opening Calculate flood loads on support walls Check if existing walls require additional remedial work to create a proper mounting surface for the system. (Plumb, level, without cracks and expansion joints, solid concrete) Select mounting brackets 4. 5. 6. 7. = Flood elevation – opening sill elevation • Standard or customized (hidden) 18

MEMBRANES AND SEALANTS Coating on a below-grade wall 32
SELECTION OF SEALANTS/COATINGS • Duration and depth of flooding • Applicability with existing construction materials • Installation applicability • Interior drainage collection system 33
SEALING A BRICK-FACED WALL DFE 34
SELECTION AND DESIGN OF A BRICK VENEER SEALANT SYSTEM • Footing capacity vs. additional loading • Duration and depth of flooding • Applicability with existing construction materials • Installation applicability • Connection to top of wall • Wall reinforcing as required • Interior drainage collection system 35
WRAPPED SEALING SYSTEMS 36
DRAINAGE SYSTEMS Inside and outside walls Reduce seepage through saturated walls and slab joints Interior drain systems Overwhelmed or clogged Pumps matched to loads 37
DRAINAGE SYSTEMS: EXTERIOR Typical Masonry Block Wall Construction Reduce seepage and pressure against below-grade walls Basements Parge and cover foundation walls Install perforated pipe underdrains Excavations : backfill and compact to densities equal to undisturbed soil French drains Exterior underdrain systems 38
PUMPS AND EMERGENCY POWER Internal drainage rate Sump pump location Discharge piping route Pump size selection Electrical specifications Pump considerations: Capacity and head Switch reliability Long-term power source and fuel Air intakes during a flood 39
CHECK VALVES AND DRAINS Drain height vs. flood elevation Check codes re backflow valves Layout drains Set drain pipe sizes Specify backflow valves 40
ANCHORS • • Prevent floatation, collapse, shifting Core slab area anchors overcome buoyancy Wall-footing anchors overcome base shear In-ground fuel tanks often buoyant – Anchor at 1. 5 x potential buoyancy 41
MECHANICAL AND ELECTRICAL SYSTEMS • Best to elevate • Fully sealing all utilities is not possible*. – Dry floodproofed locations are best alternative Elevated generators at U-Texas Vulnerable transformers in Cedar Rapids, Iowa * “Some electrical equipment is designed to operate under water and can be floodproofed. However, electrical equipment for submerged use is expensive, not readily available, and impractical for many electrical components and devices. ” (FEMA P-936) 42
CLASS EXERCISE: FLOODPROOFING CERTIFICATE SECTION III: FIND THE FLOOD DATA – Datum: – FIRM Map Information Good starting points for NYC: FEMA FIRM 360497 FEMA FIS 360497 43
SECTION III: DESIGN FOR COMPLIANCE “The structure, together with attendant utilities and sanitary facilities, is watertight to the floodproofed design elevation indicated above, with walls that are substantially impermeable to the passage of water. “All structural components are capable of resisting hydrostatic and hydrodynamic forces, including the effects of buoyancy, and anticipated debris impact forces. ” 44
