How can I tell what content has changed in this version?

 
The changes to the content for this year are as follows:

 Major changes:

• Chapter 6.2 'External timber framed walls' has had its first major revision for many years. With continuing growth in the number of timber frame homes being constructed and that it is now possible to go to seven storeys, suitable detailing to accomodate the differential movement between the timber frame and other elements is critical. The Chapter provides guidance on how much movement is likely to occur and where. New certification procedures are also introduced.

• The CD version of the Standards now contains an electronic calculator to determine foundation depths when building near trees. The Chapter 4.2 electronic calculator replaces the old slide rule and is quicker and easier to use. The calculator can also determine the most onerous tree and give guidance on heave precautions.

Minor change:

• Chapter 7.1 'Flat roofs and balconies' has been revised to take account of the recently introduced designations for reinforced bitumen membranes, contained in BS 8747.

All minor changes are identified by a red vertical marker adjacent to the relevant paragraph and the revised text underlined in red. 

Can I print out the Standards?

At the top of each page you will find a ‘Print this page’ link which will enable you to print out individual sections. The prints produced are in a printer-friendly format, however if you require a full hard copy we suggest you use the PDF version also found on the CD or purchase a hard-copy from the e-shop at www.nhbcbuilder.co.uk (opens in a new window).

Please note:

Throughout this application of the Standards coloured content text is used as follows:

• Red text = Technical Requirements that must be met by the builder
• Black text = Performance Standards for Design, Materials and Sitework.
• Blue text = Guidance (on how the Performance Standards may be met).

All links in the application will be displayed in blue to indicate they provide access to another part of the application, the colour coding outlined above relates to body text only.
