Building Log Book Requirements – Part 2

Posted on July 20th, 2007 by Tony Dolling.
Categories: Building Log Books.

For the majority of buildings the Log Book should comprise of fifteen sections, containing information as indicated below. This part contains Sections 1 to 6.

Section 1. Updates and Annual Reviews

This Section has a table to record the updates and reviews made to the building and its systems during its lifetime. The log book should be reviewed annually as part of the organisation’s quality assurance system and an entry should be made for each review. Where the log book has been updated then the changed pages should be recorded.

Section 2 Purpose and Responsibilities

This Section contains statements of purpose, the log book author contact details, the facilities manager contact details and a statement of the facilities managers responsibilities.

Section 3 Links to other Key Documents

This Section should contain the location of other key documents such as the emergency procedures, health & safety file master index, hazard register, O&M Manuals, maintenance schedules, asset register, BMS Manual, record drawings and equipment log books such as the boiler log book.

Section 4 Main Contacts

This Section should contain all of the major construction participants – both design and build, along with the primary emergency contacts and those for the electrical and gas supplies.

These should include the architect, services engineers, planning supervisor, main contractor, services contractors, commissioning engineers, O&M Manual and Building Log Book authors, facilities managers and maintenance contractors.

Section 5 Commissioning, Handover and Compliance

Section 5 should contain information relating to the commissioning and handover of the building to the occupiers.

It should contain a summary of the arrangements for the commissioning – who carried it out, when and what procedures and codes were followed, such as Codes A, B, C, L, M, R and W.

The commissioning results should be summarised for each system.

Building Log Book Requirements – Part 1

Posted on July 20th, 2007 by Tony Dolling.

A Building Log Book should be an easily accessible focal point of current information for all those working in the building. It has four main functions:

· Summary of the building:

it is a summary of all the key information about the building, including the original design, commissioning and handover details, and information on its management and performance. In being a summary, it does not wholly duplicate or replace the O&M manuals. The log book is necessary for compliance with Building Regulations Part L2.

· Key reference point:

it is the single document in which key building energy information is logged. It may be regarded as the hub document linking many other relevant documents. The log book should provide key references to the detail held in less accessible O&M manuals, BMS manuals and commissioning records. It should therefore be kept in a readily accessible (designated) position in the main building operations room and should not be removed without the approval of the facilities manager.

· Source of information/training:

it provides a key source of information for anyone involved in the daily management or operation of the building and to anyone carrying out work on the building and its services. It will be relevant to new staff and external contractors/consultants and may play a role in staff training and induction.

· Dynamic document:

it is a place to log changes to the building and its operation. It is also used to log building energy performance and continual fine-tuning commissioning. It is essential that it is kept up-to-date. Alterations should only be made with the approval of the facilities manager and should be signed and dated by that person.

English & Welsh Building Regulations Part L2 – Section 3 – Building Log Books

Since April 2002 it has been a requirement of the English and Welsh Building Regulations Approved Document L2 for the owner or occupier of a building to be provided with a Log-book upon completion of any works related to the energy consumption of the building. This may be a new building, the installation of new boiler plant or new windows. Subsequent amendments to the Building Regulations have strengthened the requirements.

The Log-book should provide details of the installed building services plant and controls, their method of operation and maintenance, and other details that collectively enable energy consumption to be monitored and controlled.

This information is to be provided in a summary form, suitable for every day use. The summary could draw on or refer to information available a part of other documentation, such as the Operation & Maintenance Manuals and Health & Safety Files.

The required information to be provided in the Log-book includes:-

A description of the building, its intended use and purpose and its design Philosophy.

Schedules of the floor areas by zone, type and environmental service

The location of the major plant and equipment, with simple schematics of the relevant systems i.e. ventilation, heating, cooling, power.

Schedules of the installed plant and equipment input and output power.

Descriptions of the operational and control strategies of the energy consuming services in the building such as the heating system.

Copies of commissioning reports confirming that the building systems have been satisfactorily commissioned.

Operational and maintenance instructions to enable the occupants to maintain the original building performance during subsequent occupation.

Schedules of the buildings energy meters and sub-meters for each fuel, location, identification, description and usage instructions. These should be related to design consumptions and compared with appropriate published benchmarks.

A design assessment should be provided of the building services systems carbon emissions related to comparable benchmarks such as the Energy Consumption Guide 19 “Energy use in offices” (ECON 19).

The air permeability of the building should be measured and a report appended.

CIBSE have produced a number of templates to meet these requirements. They are called TM31. These are available at www.cibse.co.uk.

Krisco are an English company of technical authors that specialize in the production of Building Log Books to the CIBSE TM31 template to meet the requirements of Part L2 of the English and Welsh Building Regulations.

Krisco obtain all relevant information from the architects, m&e consultants, builders and sub-contractors and produce Building Log Books to meet the requirements of Part L2 of the 2006 England and Wales Building Regulations.

This article makes use of the English & Welsh Building Regulations. Please refer to Approved Document Part L2 for full details of the requirements of these regulations. A copy of these is available at www.communities.gov.uk.
