The report has said there is evidence of improvement in the local economy and the picture in the building industry was also more positive.Spokesman, Jim Sammon, said the Executive could encourage more growth by spending on infrastructure.He said: "This is growth from a low base, following a long period of contraction, and the key challenges for the sector locally remain."These include limited access to bank finance, restricted public sector demand and planning challenges.He added: "We would urge the Northern Ireland Executive to encourage and nurture recovery by increasing infrastructure spending through moving more money from current to capital spending."Infrastructure is a driver of growth and competitiveness."He added: "Like the rest of the UK, shortages in quantity surveying skills have had an impact."Quantity surveyors are involved in all aspects of the construction supply chain, so when construction activity begins to pick up, demand for quantity surveyors is particularly quick to recover."
