Bam Nuttall has posted its full year 2016 results which show a dip in pre-tax profit of £14.3M compared to £18.2M in 2015.
The figures showed that turnover was £637M, compared to £787M in 2015, producing a 2% margin.
It said it was focusing on securing a “good quality” order intake.
“The impact of the UK referendum decision is not expected to have any significant impact on our order book. Our workload is dominated by public and regulated sector customers and is consequently mostly influenced by government infrastructure related decisions. The benefits of investment in infrastructure by government seems to be well recognised now,” wrote chief executive Stephen Fox.
The firm said that one of the focuses for this year is health and safety in four areas: safety, occupational health, mental health and wellbeing and personal health.
