Preface to the One Hundred andForty-Third Edition

Recent Construction Activity Trends

Output in the construction industry grew 3month on 3month for the fifth consecutive period, rising by 0.2% in the first quarter of2017; this is in line with the estimate for construction output included in the preliminary estimate of gross domestic product forJanuary 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 Not the notion of them being out-of-date, but old in that they are well established over the last few years.Early 2017 is expected to see more of the same for the construction sector: capacity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, increasinglabour wage rates and overall optimism. Added to this are rising materials costs, primarily driven by the significant changes tosterling foreign exchange rates.

Balancing risk and reward remains a central goal of main contractors and supply chain firms. The intention is that it leads toorganic or sustainable ways of filling order books. This includes concentrating on those sectors deemed to be core to theirbusiness 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 changerecorded 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 increaseshave 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 ora challenging period over the medium-term. Future risks to monitor for UK construction delivery will relate to EU labour marketaccess and possible tariffs on materials and components.
