PREFACE

PREFACE BCIS ALTERATIONS AND REFURBISHMENT ESTIMATING PRICE BOOK 26TH EDITION Preface to the 26th edition This important addition to the BCIS range of building price books has been compiled in recognition of the importance of the building refurbishment market. The last 20 years has seen a substantial increase in the volume of building alteration and refurbishment activity in the United Kingdom. This has been encouraged by an increased awareness of the value and importance of historic buildings and the built environment. More recently, the depressed state of the economy has led to building owners and users amending plans to build and move into new buildings and consider, instead, improvements to their existing premises. In compiling this revised price book, BCIS has drawn upon the vast resources of its Building Database to provide in a single volume the most comprehensive selection possible of prices for alteration and refurbishment work, including the addition of helpful information on the Landfill Tax. As with all BCIS price books, each section is presented in an easy-to-understand layout, giving the labour time, together with a detailed cost analysis for every item of work split into labour, plant and material content. These are totalled to show a competitive and realistic total unit price requiring only the addition of the user's own profit and overheads. The format and breakdown of the unit rates allows users to make adjustments to suit local conditions with ease. The data contained in this book is intended for use on projects consisting entirely or substantially of alterations and improvements to existing buildings, from simply taking out a door and blocking up the opening, to projects up to £180,000 in value. MATERIAL PRICES Material prices used in this book are based on national average best trade prices. The base date used for these materials costs is the second quarter 2020. LABOUR RATES The Alterations and Refurbishment Estimating Price Book is based on the Building and Allied Trades Joint Industrial Council wage agreement. The wage rates agreed by the Joint Industry Board for Plumbing and Mechanical Engineering Services in England and Wales have been used where applicable. PLUS RATES In order to reflect the more costly nature of alterations and refurbishment work a plus rate of 10 pence per hour has been incorporated into the hourly cost calculation. We would recommend that users study the introduction, Section A, to familiarise themselves with the basis for pricing this year.

GENERAL INFORMATION

Section 3 Page 1

GENERAL INFORMATION The publishers include here some general information on listed buildings, as alteration and refurbishment work may well be required to be carried out on buildings of special architectural or historic interest. Buildings which may be protected by law The five categories of listed buildings are: All buildings built before 1700 which survive in anything like their original condition. Most buildings of 1700 to 1840. Buildings of between 1840 and 1914 which are of definite quality and character. Selected buildings of high quality constructed between 1914 and 1939. A few selected buildings erected after 1939. The statutory lists for England may be inspected at: English Heritage 6th Floor 100 Wood Street London EC2V 7AN OR English Heritage The Engine House Fire Fly Avenue Swindon SN2 2EH or at the office of the relevant County or District Council (in London, at the office of the appropriate London Borough Council). Listed Building Consent Anyone who wishes to demolish a listed building, or to alter or extend one in any way that affects its character, must obtain a 'listed building consent' from the local planning authority (the District or London Borough Council), or in some circumstances the Secretary of State. It is an offence to demolish, alter or extend a listed building without listed building consent. If you are granted listed building consent to demolish a building or part of a building, English Heritage must first be given the opportunity to record this fact. In this case, you should obtain a form from your Local Authority to give notice to the relevant English Heritage regional office. Alterations to Listed Buildings Useful guidelines on alterations to listed buildings are contained in Appendix IV of the Department of the Environment Circular 8/87 dated 25 March 1987. This gives advice on the restoration, repair and replacement of various features of listed buildings, so that any items will be in keeping with the general character and style of construction. Precise details of when English Heritage should be consulted are set out in the Planning (Listed Buildings and Conservation Areas) Act 1990 as amended, DETR Circular 01/2001 and the Town and Country Planning (Development Management Procedure) (England) Order 2010. Local Authority Grants Local authorities may make grants for a building of architectural or historic interest and are not restricted to outstanding or listed buildings. Enquiries should be addressed to the appropriate local authority. Further Information For more details regarding proposed alterations to, or refurbishment of, listed buildings, contact the local authority concerned, or the Department of the Environment (See Section 5 for addresses).

INTRODUCTION BCIS ALTERATIONS AND REFURBISHMENT ESTIMATING PRICE BOOK FOR SMALL PROJECTS AA GENERAL

001 Basis of pricing 002 The aim of this book is to provide builders and building Consultants with a GUIDE to the current (net cost) unit prices for building alterations and refurbishment

work at competitive rates. 003 The prices in this book are intended for projects consisting entirely or substantially of alterations and improvements to existing buildings, from simple operations

such as taking out a door and blocking up the opening to complete refurbishment projects up to a value of £180,000. 004 This Database has been created on a nationally averaged 'best price' basis. For an indication of regional differentials, please refer to sub-section AF - 'Regional

Variations'. These factors should be considered if local rates of labour and material are not known at the time of estimating. 005 The Database prices represent the net cost of labour, plant and materials, without additions for site overheads (examples of which are shown separately in

section B - Preliminaries) or for off-site office overheads or profit, as such additions fluctuate with market conditions and require management policy decisions at the time of tender.

006 Prices for work which is normally executed under the Builder's direct control, whether employing in-house labour or labour only sub-contractors, are broken down

into 'Net Labour', 'Net Plant' and 'Net Materials', with the aggregate of these separate prices given in bold type under the heading of 'NET UNIT PRICE'. 007 Work normally undertaken by specialist sub-contract firms has been priced by specialist firms and the prices given are total 'Net Unit Prices' inclusive of labour,

plant, materials and the specialists' overheads and profit. The prices are inclusive of 2.5% cash discount to the Builder but are exclusive of the Builder's own overheads and profit, general and special attendance.

008 Guide prices 009 It must be stressed that the prices in the book are GUIDE prices. Quotations for materials and specialists' work should be obtained for particular projects as the

prices cannot be guaranteed. The nature of the publication, which is intended to be a guide to building prices throughout the United Kingdom, precludes the possibility of firm prices for all situations. Regional price variations, qualities and quantities of materials and work, availability of skilled labour, location of sites and individual project requirements all have a bearing on prices for building work.

010 Descriptions 011 Descriptions of work are based upon the Sixth Edition of the Standard Method of Measurement for Building Works (SMM6). 012 Value Added Tax 013 The prices throughout the book are EXCLUSIVE of Value Added Tax. 014 Covid-19

The supply prices of materials and plant hire charges are based on the data collected during the second quarter of 2020 and in some circumstances will need to be adjusted in the short-term for the effect of the Covid-19 Lockdown. Constants for labour are based on working practices common in the first quarter of 2020 and do not reflect the effect of implementing Covid-19 Safe Operating Procedures and again, in the short-term an adjustment may be necessary to reflect changes in productivity. Users should consider including an adjustment for the Covid-19 impact for estimates based on BCIS Schedule or Rates and Price Books unit rate data. The Covid-19 restrictions and the implementation of compliant Safe Operating Procedures may also affect Site Overheads, potentially bringing about lengthening and thickening of preliminaries due to extended contract periods, the increased cost of supervision, additional welfare facilities and provision of PPE. Off-site office overheads and profit may also need to be adjusted to reflect market conditions brought about by the Covid-19 pandemic such as reduced demand, reduced availability of resources, increased overheads and/or reduced profit. In light of current uncertainty over price movements, we will issue an in-year update to help our users ensure their estimates are informed with the latest data. This update to Tender Price movements, summary of labour, material and plant input costs will be made available to customers who purchase price books and/or subscribe to BCIS Schedule of rates online.

AB BASIC MATERIAL PRICES

001 Base date of prices 002 The supply prices of materials, as shown in 'Basic Prices of Materials' at the beginning of each work section were current during the second quarter of 2020. 003 Delivery 004 The supply prices of major items of building materials are given as "delivered to site" (unless otherwise stated) with allowance for delivery charges, if applicable,

being made in rates to "average" sites, typically in an area of a conurbation (e.g. Greater London area) up to about 50 miles from the source of supply. Deliveries to city centre sites (particularly central London) and to more remote rural sites may attract delivery surcharges and additional allowance in such cases will need to be made in "overheads". The supply of ancillary materials is taken to be ex Builders Merchants, with site delivery or collection.

005 Trade and quantity discounts 006 The supply prices of materials generally are net Trade prices and are for part loads or small quantities. 007 Waste factors 008 Waste percentages added to the supply prices of materials are generally for handling wastage, for such materials as cement, sand and lime. The percentages

added to other materials are generally for waste in use and in order to simplify the computation of the material constants used in the calculations of the Net Unit Prices.

009 Unloading costs 010 Where materials are not supplied crated or palletised, the cost of site labour and plant in unloading materials has been shown separately, where applicable, and

added to the supply prices. 011 Crates and pallets 012 Surcharges for returnable crates and pallets have been excluded from the supply prices of the materials.

AC PLANT COSTS 001 Plant hire charges are applicable to the second quarter of 2020 and are typical rates obtained from plant hire companies. The hire charges for plant show hourly

rates which have been calculated based upon DAILY hire charges, due to the intermittent short-term usage to be expected in alteration and refurbishment works. If sustained, longer-term use of any items of plant can be justified for the works, considerable savings in hire charges may be anticipated.

At the time of publication prices for plant hire were very competitive and Contractors are advised to obtain competitive quotations at the time of preparing tenders.

002 Idle time 003 Allowances have been made against the hire charges to allow for idle or standing time so that the hourly constants shown in the build-up of prices are for the

actual working time of the plant. 004 Operators 005 Weekly hire charges for mechanical equipment are exclusive of operators. The costs of operators are shown separately and are calculated in accordance with

the build-up of labour rates shown in Sub-Section AD. 006 Daily or hourly hire charges for mechanical equipment are inclusive of operators where indicated. 007 Fuel etc. 008 The hire charges for mechanical equipment exclude the provision of fuel but include maintenance and services charges. Unit rate build-ups include for fuel costs. 009 Constants 010 The constants, in the form of hours, against the items of plant have been rounded off to two decimal places after calculation. AD LABOUR COSTS

001 Generally 002 Labour costs have been calculated in accordance with the recommendations of the Code of Estimating Practice published by the Chartered Institute of Building. 003 Base date of pricing 004 Labour costs are based upon the operative rates of wages and allowances effective from 22nd June 2020 for BATJIC and effective from 6th January 2020 for

JIB and JIBPMES. 005 Hourly rates 006 The hourly rates used for the calculations in this book are as follows:

Advanced Craft BATJIC = £18.50 per hour General Operative BATJIC = £14.04 per hour General Operative BATJIC (skill rate A) = £14.68 per hour General Operative BATJIC (semi-skilled A) = £16.27 per hour General Operative BATJIC (skill rate B) = £15.05 per hour General Operative BATJIC (semi-skilled B) = £16.68 per hour General Operative BATJIC (skill rate C) = £15.42 per hour General Operative BATJIC (semi-skilled C) = £17.07 per hour Technical Plumber = £26.70 per hour Advanced Plumber = £24.07 per hour Trained Plumber = £20.39 per hour Apprentice Plumber (3rd year) JIBPMES = £12.33 per hour

007 The Total Cost per Hour figures have been corrected to the nearest whole penny and are based on a 39 hour working week. However, the detailed calculations

have been made using several places of decimal which may give rise to apparent 1p differences in some printed figures. 008 Plus rates 009 An enhanced 'plus rate' has been inserted in the calculation to allow for the more costly labour element of refurbishment work. 010 Travelling allowances 011 As travelling allowances vary with the distance of building sites from the Builder's office they have been excluded from the calculation of the hourly labour costs.

Allowances for travelling time and/or expenses should be made in Preliminaries. 014 Overtime 015. The non-productive element in the overtime amounts to an average of 37 hours per operative per annum. 016 Other emoluments 017 With effect from 15th June 1998, tool allowances have been consolidated into the basic rate of pay. 018 Constants 019 The constants, in the form of hours, against each item in the price book have been rounded off to two decimal places after calculation. 020 Calculation of hours worked per annum: Advanced Craft and General Operatives

(a) Summertime working: 30 weeks of British Summertime at 40.6 hours per week Monday to Friday hours hours hours 30 Weeks at 40.6 hours 1218.0 Less annual holidays (15 days) 121.8 public holidays ( 5 days) 40.6 162.4 1055.6 ----- ------ (b) Winter working: 22 weeks at 40.6 hours per week 22 Weeks at 40.6 hours 893.2 Less annual holidays ( 7 days) 56.8 public holidays ( 3 days) 24.4 Sick leave (8 days) 65.0 146.2 747.0 ----- ----- ------ Total Number of paid working hours during year 1802.6 Less Allowance for inclement weather (2%) 36.1 ------ TOTAL NUMBER OF PRODUCTIVE HOURS WORKED PER ANNUM 1766.6 ------
