Structural Drying >> Structural Drying Log

If an intrusive/penetrating moisture meter is not available, a non-intrusive, penetrating moisture meter (Figure 3b) may be used; however, keep in mind that the material moisture results measured from non-intrusive meters may be less accurate than intrusive meters. Kitchen cabinets, bathroom vanities, and other "built-in" furnishings that were subjected to flood water should be removed from their location to permit drying of the Structural Drying Log material behind them. 

Once these "hidden" areas are dried, the furnishings can be reinstalled if they are salvageable. When saturated wood, drywall, and/or other structural materials vulnerable to fungal growth are naturally air dried over an extended period (weeks), Structural Drying Log the application of a disinfectant prior to drying can prevent mold growth. 

Materials should be closely observed and disinfectant reapplied at the first sight of mold. General Notes for Drying Foundation Floors Crawlspaces. Access to crawlspaces is necessary for decontamination purposes. For crawlspaces that do not have an existing access opening, Structural Drying Log the simplest method to access the crawlspace is by strategically removing sections of overlying flooring to permit access. 

When the flooring is not salvageable, removal of the flooring provides the necessary access openings. Once access is obtained, gross (solid) contamination should be removed from the ground underneath the building for health and sanitation purposes. Next, Structural Drying Log any remaining water should be removed. 

If there is an existing vapor retarder on the ground, it can be left in place to collect spent water and cleaning solutions. Following remediation and any necessary final cleaning, Structural Drying Log the vapor retarder can be left in place to facilitate drying. If there is exposed ground within the crawlspace after cleaning, it should be covered with a plastic vapor retarder to minimize potential mold growth and future moisture migration into the house. 

Plastic vapor retarders can be made watertight by overlapping and sealing them together using either glue or heavy-duty adhesive. Suitable adhesives can be obtained from hardware stores or home improvement centers. After the vapor retarder is placed, Structural Drying Log the underlying support structure of salvageable wooden floor joists, wood sub-floors, and foundation walls should be cleaned and sanitized. 

Following cleaning, application of a wood preservative will provide protection against fungi Structural Drying Log and wood destroying insects.•Grade slabs. Concrete grade slabs provide a dense barrier between the ground and the interior of the home. Remove mud and gross contamination from slabs by shoveling into suitable containers. 

Reduce soil and contaminant levels on surfaces by flushing off with clear water. The fastest and most efficient method to clean and decontaminate contaminated grade slabs Structural Drying Log and adjacent building materials and surfaces is by using a residential type of pressure washer to apply a cleaner-disinfectant solution to affected areas. 

Brushes improve decontamination of floors and base of walls by scrubbing solution into affected surfaces. Following the first cleaning, floors and base of walls should be rinsed with water Structural Drying Log and the cleaning process redone a second time. Squeegees can be used to control or direct spent solution, and wet vacuums can be used to collect spent solutions. 

Following cleaning, the slab should be visually examined for signs of heaving or cracking due to hydrostatic pressure. When in doubt, contact the local building inspector, Structural Drying Log structural engineer or other appropriate professional.Notes to Table: 1. The loads are based on the 2005 edition of ASCE 7. The resistance includes equipment weight.

The Base Case of the tabulated numbers of #12 screws (or ¼ pan-head screws for flange-attachment) is a 90-mph basic wind speed, 1.15 importance factor, 30' building height, Exposure C, Structural Drying Log using a safety factor of 3. 3. For other basic wind speeds, or for an importance factor of 1, multiply the tabulated number of #12 screws by to determine the required number of #12 screws or (¼ pan-head screws) required for the desired basic wind speed, VD (mph) and importance factor.

For other roof heights up to 200', Structural Drying Log multiply the tabulated number of #12 screws by (1.00 + 0.003 [h - 30]) to determine the required number of #12 screws or ¼ pan-head screws for buildings between 30' and 200'.Example A: 24" x 24" exhaust fan screwed to curb (table row 7), Base Case conditions (see Note 1): 2.5 screws per side; therefore, round up and specify 3 screws per side.

Example B: 24" x 24" exhaust fan screwed to curb (table row 7), Base Case conditions, except 120 mph Structural Drying Log and importance factor of 1: 1202 x 1 902 x 1.15 = 1.55 x 2.5 screws per side = 3.86 screws per side; therefore, round up and specify 4 screws per side.Example C: 24" x 24" exhaust fan screwed to curb (table row 7), Base Case conditions, except 150' roof height: 1.00 + 0.003 (150' - 30') = 1.00 + 0.36 = 1.36 x 2.5 screws per side = 3.4 screws per side; therefore, round down and specify 3 screws per side.

This factor only applies to the long sides. At the short sides, Structural Drying Log use the fastener spacing used at the long sides. Fan Cowling Attachment: Fans are frequently blown off their curbs because they are poorly attached. When fans are well attached, the cowlings frequently blow off (see Figure 3). 

Unless the fan manufacturer specifically engineered the cowling attachment to resist the design wind load, cable tie-downs (see Figure 4) are recommended to avoid cowling blow-off. For fan cowlings less than 4 feet in diameter, Structural Drying Log 1/8-inch diameter stainless steel cables are recommended. Cowlings blew off two of the three fans shown in this photo. Cowlings can tear roof membranes and break glazing. 

To overcome blow-off of the fan cowling, this cowling was attached to the curb with cables. [end of caption]For larger cowlings, use 3/16-inch diameter cables. When the basic wind speed is 120 mph or less, specify two cables. Where the basic wind speed is greater than 120 mph, Structural Drying Log specify four cables. 

To minimize leakage potential at the anchor point, Structural Drying Log it is recommended that the cables be adequately anchored to the equipment curb (rather than anchored to the roof deck). The attachment of the curb itself also needs to be designed and specified.
