Construction activity for November grows: AiG survey AUSTRALIA'S construction industry expanded at a faster rate in November than the previous month, according to the Australian Industry Group. The AiG performance of construction index printed at 55.2 points in November, a lift of 0.8 points compared with October. This is only the second consecutive month that the sector has been in expansionary territory. A reading above 50 indicates expansion, while a reading below 50 indicates contraction. AiG said a strengthening in new orders and an upturn in deliveries from suppliers boosted conditions. Businesses noted higher levels of demand, increased tender opportunities and further success in securing contracts, according to the survey. House builders reported customer inquiries were sustained at high levels and solid investor activity was providing support. Survey respondents cited tight credit conditions and a lack of public sector tenders as the main constraints on activity.
