Mr Gillespie said the group's Morrison Construction arm has benefited from relatively strong levels of public sector activity in Scotland.
The division has been performing better in Scotland than anywhere in the UK for Morrison "in terms of growth and the pipeline," he said.

Mr Gillespie renewed the support for the Scottish Government's infrastructure investment policies he voiced then.
"The Scottish Government has recognised the positive effect on the economy that construction can have in terms of investment in infrastructure.
"They have been with it for some time and created a very positive pipeline of opportunities.
Morrison belongs to a coalition that was recently named as one of two preferred bidders for the M8, M73 and M74 improvement scheme.
Regarding the UK Coalition Government, Mr Gillespie said: "I don't think they have quite got the key relationship between infrastructure and economic recovery."

Mr Gillespie said conditions were not strong enough in Scotland to encourage the firm to make the investment required to challenge established players in areas such as the central belt.
It has a small number of sites in the Highlands.
