10/21/2014 BUILDING CONSTRUCTION RIO HONDO TRUCK ACADEMY Why do firefighters need to know about Building Construction???? We must understand Building Construction to help us understand the behavior of buildings under fire conditions. Having a fundamental knowledge of buildings is an essential component of the decisiondecision--makingmaking process in successful fireground operations. We have to realize that newer construction methods are not in harmony with fire suppression operations.

A ‘truss’ is formed when structural members are joined together in triangular configurations. The truss is one of the basic types of structural frames formed from structural members. A truss consists of a group of ties and struts designed and connected to form a structure which acts as a large span beam. The members usually form one or more triangles in a single plane and are arranged so that the external loads are applied at the joints and theoretically cause only axial tension or axial compression in the members. -
Roof and Gutter De-Icing Cable
ROOF AND GUTTER DE-ICING CABLE Design and Installation Guide Industrial Residential CommeWhat are Ice Dams? How Ice Dams are formed 1 Rising heat from the house melts the blanket of snow and ice on the roof from the bottom up, sending water trickling down the roof. 2 When water arrives at the cold eaves, it refreezes and forms a dam, preventing drainage. 3 Water is trapped behind the dam and backs up under the shingles. 4 The melted water can leak into the house through the windows or ceiling Snowmelt Principles and Application: Electrical Heat Trace Cable is intended to provide drain paths for the melted or flowing water to be carried away from the roof, gutters, and down spouts. This system is not intended to provide a snow free surface. Roofs in General Sun and building heat combine to melt accumulated snow at the roof/snow interface. Snow is porous and allows water to flow. Ice is not porous and will trap water. Water will flow as long as the roof surface stays above freezing. When the water runs to the roof edge it freezes, starting an “ice dam” that continues to grow and trap more water, leading to leakage problems. The objective of a snowmelt system is to ensure the water is drained off and not allowed to freeze at the roof edge forming a dam. Gutter Damage from Ice The water that enters into your rain gutters can freeze and build up an enormous amount of weight many times causing water to leak into soffits and entering into the building. -
Gutter System Installation Standards Product Specification
Gutter System Installation Standards Product Specification Property of: Spectra Metal Sales Gutters and Leaf Protection Introduction A Rain Gutter System starts with a trough, called a gutter, which collects rainwater from the roofline of a house and diverts it away from the structure, using elbows and downspouts. • The purpose of this diversion is to prevent water flow off the roof edge which can cause structural damage over time to the walls and/or foundation of a house. • The gutter system is more important to the exterior of your home than the actual paint, siding, or even windows, because it protects your home from rot, mold, mildew, and flooding. • This water damage, without a gutter system, occurs slowly, spreads quickly, and is unnoticeable until the damage repair is substantial. • For your gutter system to work properly, it must be able to empty out the water faster than it fills up. In order to ensure the proper flow of water, a few are vital to the success of the overall gutter system: 1) Seamless gutters 2) Gutter and downspout sizing 3) Slope or pitch of gutter 4) Downspout placement 5) Keeping the gutters debris free 6) Using quality parts and accessories 2 Gutter Specifications Scope of Guide A) The Rain-carrying system consists of all necessary components to complete installation with products manufactured or endorsed for use by Spectra Metal Sales. System Components A) Gutters shall be made of 3105-H24 aluminum and shall be continuous and seamless with a minimum thickness gauge of .032” or .027” (+/- .002” nominal). B) All pre-painted components will have an approved SMS Finish and Color. -

Draft Mansard Roof Guidance 201115
London Borough of Tower Hamlets DRAFT MANSARD ROOF GUIDANCE NOTE Draft for consultation November 2015 0 Draft Mansard Roof Guidance Purpose of this consultation The purpose of the Mansard Roof Guidance Note is to support residents who would like to make a planning application for a new mansard roof in one of the Borough’s Conservation Areas. The Draft Mansard Roof Guidance Note contains information on the most relevant planning policies that the Council must consider when making decision on planning applications; the character of historic roofs in Tower Hamlets; the elements of Mansard Roofs and best practice advice on how you should approach the design of a new mansard roof in a conservation area; and finally, the document includes some helpful tips for you to refer to when making a planning application for a new mansard roof in a Conservation Area. In order to assist residents with planning application process, officers have also examined the following eight Conservation Areas in more detail to identify the best opportunities for properties to extend: Driffield Road; Medway; Fairfield Road; Victoria Park; Jesus Hospital Estate; York Square; Chapel House; and Tredegar Square. Officer recommendations have been presented in draft addendum to the relevant Conservation Area Character Appraisals. These addendums are also subject to consultation from 23 November 2015 and 18 January 2016. More information on these can be found via the links and contact details below. How you can get involved It is important that this Guidance Note is easy to understand and useful. If you feel that this document could be improved and the information better communicated, we would be grateful for your feedback during the public consultation. -
