v. 21/97
This supplement to Technical Note 21/97 provides a visual interpretation of the drawing definitions recommended therein. It clarifies which types of drawing would typically be produced under different types of design appointment. It also presents definitions of sketch drawings, detailed design, co-ordination, installation and record drawings, and installation wiring diagrams.

Space and Weight Allowance for Building Services Plant
by M. Hejab and C. J. Parsloe
Published June 1993
Plant area allowances should incorporate sufficient space to permit the successful installation of the plant, and to allow on-going inspection and maintenance tasks to be conducted safely and efficiently. However, during the preliminary design stage of a project, the designer may not be aware of the actual plant to be installed. Nevertheless, a decision must be made with regard to plant area and weight allowances in order to permit structural and architectural designs to proceed. This volume provides guidance on suitable space and weight allowances for different plant items incorporating space for maintenance and installation. The space and weight required by the different plant items has been related to the output capacity of the plant. A ready means of obtaining estimates for output capacity can be found by reference to BSRIA "Technical Note 5/88.1, Rules of Thumb". For a given duty there may be a wide variation in the space and weight required between the various manufacturers' equipment. The lines presented are best fits to the manufacturers' data obtained.

This study based on the findings of an 18-month research project investigating power loads for office equipment in buildings, managed in close liaison with BRESCU, the Building Research Energy Conservation Unit. The full report for this work is Report No. 63310/1 "Power Demands due to Portable Office Equipment". The research programme was divided into separate work areas for site monitoring and market research. The site monitoring work involved recording power demand values for individual machines in use in offices, and for entire office areas incorporating a number of mixed machines. The market reseach involved conducting a questionnaire survey of companies to determine the number of equipment items in offices and how they were being used. There is a further review of predictions for future office equipment trends. The project findings indicate that there are a number of key factors influencing the size of small power loads in offices, and that given sufficient information, a realistic estimate of the load can be made.

This title compares different countries' approaches to the design and installation of building services systems. The UK approach is compared with those in the USA, France and Germany. The report was commissioned to identify the reasons for apparently high UK construction costs compared to those in other industrialised countries. The book addresses the accusation of "over-engineering" which has been levelled at UK building services designers and installers and compares UK standards and best practice guides with those applied in the other countries, with particular reference to estimation of heating and cooling plant capacities, ductwork and fan sizing, pipework and pump sizing, and system commissioning. It draws conclusions which highlight specific differences between the UK approach and that in other countries and makes recommendations by which UK methods could be modified to achieve significant cost savings.

The space requirements for services in modern buildings can be considerable. The proper allocation and planning of service areas can result in significant improvements in the efficiency of installation and the long-term maintenance of the systems. Produced as part of BSRIA's programme of work under "Design for Maintainability", this document provides updated and revised information drawn mainly from BSRIA's earlier publication TN 3/79 "Space Requirements for Building Services Distribution Systems - Detail Design Stage".
