and Forty-Third Edition Recent Construction Activity Trends Output in the construction industry grew 3 month on 3 month for the fifth consecutive period, rising by 0.2% in the first quarter of 2017; this is in line with the estimate for construction output included in the preliminary estimate of gross domestic product for January to March 2017. New year, old trends. Not the notion of them being out-of-date, but old in that they are well established over the last few years. Early 2017 is expected to see more of the same for the construction sector: capacity constraints, good workload, increasing labour wage rates and overall optimism. Added to this are rising materials costs, primarily driven by the significant changes to sterling foreign exchange rates. Balancing risk and reward remains a central goal of main contractors and supply chain firms. The intention is that it leads to organic or sustainable ways of filling order books. This includes concentrating on those sectors deemed to be core to their business planning, seeking work from repeat customers and being a contractor of choice for clients where negotiated pro- curement plays a greater role. Additionally, balanced risk and reward also extends to procurement routes and the level of bid- ding competition – in other words, how many and which competitors are on the tender list. Construction prices rose over the year at Q1 2017 by 5%, according to AECOM’s tender price index. The yearly rate of change recorded at Q4 2016 is also revised upwards to 5.8% from the provisional figure of 5.5% reported towards the end of 2016. This yearly rate of change keeps the run rate of construction price inflation above the long-run average. Recent price increases have experienced greater upwards pressure from rising input costs. Brexit remains a major talking point – but that is mostly what it is, in the absence of any substantive negotiations commencing. Some starting positions are emerging. However, it is still unclear whether Brexit is a tipping point that presages larger change or a challenging period over the medium-term. Future risks to monitor for UK construction delivery will relate to EU labour market access and possible tariffs on materials and components. Materials Construction materials experiencing the largest price increases in the 12 months to March 2016 in the UK are shown in the table below: Construction materials Change between February 2016 and February 2017 Concrete reinforcing bars +27% Imported sawn or planed wood +14% Fabricated structural steel +11% Imported plywood +9% Insulating materials (thermal or acoustic) +4% Ready-mixed concrete 0% Paint (aqueous) −1% Clay bricks −2% Builders’ ironmongery −2.5% From February 2016 and February 2017 the average rise for the BIS recorded materials show an increase of 3%. Labour – Wage Agreements Construction labour rates continue to rise on a yearly basis. This adds additional pricing pressure for the supply chain. Construction Industry Joint Council Following negotiations between the parties to CIJC, the council agreed a two-year agreement on pay and other conditions in August 2016. Hourly pay rates were increased by 2.5% from 25 July 2016 and then by a further 2.75% from June 2017. Industry sick pay and subsistence allowance also increased in line with the basic pay rate increases. Workers received an extra day’s holiday from 1 January 2017 which is worth an additional 0.4%. For more details on apprentice rates, daily fare and travelling allowance and other rates refer to CIJC document IR.2016.19. Book Price Level The price level of Spon’s A&B 2018 has been indexed at 595. Readers of Spon’s A&B are reminded that Spon’s is the only known price book in which key rates are checked against current tender prices. Users should note that this number is based on book prices arrived at by pricing our usual tender price models with prices taken from the book. It does not reflect a particular date which would appear in our normal published indices. Profits and Overheads The 2018 edition includes a 5% allowance main contractor’s overheads and profit. Preliminaries There are the first signs that main contractor preliminaries costs are being adjusted from the one-way traffic of recent years. Indirect costs have steadily increased for the last few years. Now though, there are the first signs of a break in this trend for preliminaries. Whilst this is not across the board, and depends to a large degree on the project parameters, this is a likely response to industry output changes, lingering uncertainty for the medium-term and the need to retain a competitive edge. We have set our example provision for preliminaries this year at 13.2%. � Preliminaries are not included within the main Prices for Measured Works or in the Approximate Estimating Rates sections of the book. � Preliminaries are included in the rates within Building Prices per Functional Unit and Building Prices per Square Metre sections. Prices included within this edition do not include for VAT, professional fees etc. which must be added if appropriate. PARTS OF THIS BOOK Part 1: General This section contains advice on various construction specialisms; capital allowances; legislation; taxes; insurances; building cost and tender price indices and regional price variations. Part 2 Rates of Wages and Labour Shows current industry level wage agreement rates and how we have built up the gang labour rates being used in the book. x Preface Part 3: Approximate Estimating This section contains distinct areas: � Building Prices per Functional Unit; Building Prices per Square Metre and Building Cost Models. It should be noted that these sections all include site preliminaries. The only occasion this happens within the book. � Approximate Estimating Rates shows typical composite built-up rates organized by building elements. Please note these rates do not include for any site preliminaries. There is also a section where we show typical preliminaries build up for a project valued at approximately £4,000,000. This is intended for guidance only and should not be used as part of any tender submission. Part 4 Prices for Measured Works These sections contain Prices for Measured Works organized using the NRM2 Work Sections for building works. NOTE: All prices in Part 4 exclude the main contractor’s preliminaries costs. Part 5: Fees for Professional Services This section contains guidance on fee levels for professional services; Quantity Surveyors; Architects’ and Consulting Engi- neers. Readers should always obtain fee proposals for their project prior to commencement as there are many factors that influence fee submissions. NOTE: Professional fees are not included in any rates in the book. Part 6: Daywork and Prime Cost This section contains Daywork and Prime Cost allowances issued by the Royal Institute of Chartered Surveyors. Part 7: Useful Addresses for Further Information A list of useful trade associations, professional bodies contact details. Part 8: Tables and Memoranda This section contains general formulae, weights and quantities of materials, other design criteria and useful memoranda asso- ciated with each trade.
