  • 078400S02 FIRESTOPPING – Mechanical Room Floor Penetrations
    078400S02 FIRESTOPPING – Mechanical Room Floor Penetrations The following standard applies to all added floor penetrations in any existing mechanical room, electrical room or penthouse mechanical area above slab level in all facilities maintained by the University of Kentucky. Affected penetrations include, but are not limited to, the following: conduit, pipes, and ductwork. For new facilities, housekeeping curbs should be constructed during the initial building construction which would eliminate the need for this standard. 1.0 All penetrations must be fire stopped per the applicable NFPA (National Fire Protection Association) and State of Kentucky Building Codes with the appropriate UL listed fire stop assembly being utilized. The UL listing documentation must be available for the installed assembly upon request by the inspecting authority or by the University representative. 2.0 In addition to the required fire stopping outlined in section 1.0 above, all penetrations are to be protected by materials meeting an UL Tested Class 1 W-rating to restrict the flow of water. 3.0 For pipes and conduits, a curb is to be installed around the opening with a self leveling, single- component, silicone-based firestop sealant used in the slab and the curb. The installation is to consist of a steel angle mechanically fastened to the floor to create a curb with the firestop sealant installed in the curb and slab sealing up to the penetrating item. The sealant is to be white in color. See drawing 1 below for better clarification. 4.0 For ductwork, a curb is to be installed around the opening with a self leveling, single-component, silicone-based firestop sealant used in the slab and the curb.

  • Basement Flood Mitigation
    1 Mitigation refers to measures taken now to reduce losses in the future. How can homeowners and renters protect themselves and their property from a devastating loss? 2 There are a range of possible causes for basement flooding and some potential remedies. Many of these low-cost options can be factored into a family’s budget and accomplished over the several months that precede storm season. 3 There are four ways water gets into your basement: Through the drainage system, known as the sump. Backing up through the sewer lines under the house. Seeping through cracks in the walls and floor. Through windows and doors, called overland flooding. 4 Gutters can play a huge role in keeping basements dry and foundations stable. Water damage caused by clogged gutters can be severe. Install gutters and downspouts. Repair them as the need arises. Keep them free of debris. 5 Channel and disperse water away from the home by lengthening the run of downspouts with rigid or flexible extensions. Prevent interior intrusion through windows and replace weather stripping as needed. 6 Many varieties of sturdy window well covers are available, simple to install and hinged for easy access. Wells should be constructed with gravel bottoms to promote drainage. Remove organic growth to permit sunlight and ventilation. 7 Berms and barriers can help water slope away from the home. The berm’s slope should be about 1 inch per foot and extend for at least 10 feet. It is important to note permits are required any time a homeowner alters the elevation of the property.

University of Nebraska, 2011 Advisor: Betsy Gabb The office workplace within the United States has undergone monumental changes in the past century. The Environmental Protection Agency (EPA) has cited that Americans spend an average of 90 percent of their time indoors. As human beings can often spend a majority of the hours in the day at their workplace, more so than their home, it is important to understand the effects of the built environment on the American office employee.

These are all real-world scenarios where the ButterflyMX system has been installed with elevator controls. This document assumes that the reader has a basic level of familiarity with our hardware, for example making sure one wire is terminated to B, and one to IN. For additional documentation on our elevator control system refer to: http://butterflymx.com/resources Scenario 1: “I want a floor-by-floor lockout.” Floor 6 Solution: The lockout scheme determined by the elevator controller is accommodated by the Floor 5 ButterflyMX ECS. Each floor is locked out by default and there is a card reader in the elevator cab. Residents use their key fob to access the Floor 4 floor that they live on. When a visitor calls a resident from the ButterflyMX Touchscreen at Floor 3 the building access point, the resident grants them access and the floor that the resident lives on is unlocked in the elevator cab.
