The firm said revenue particularly at its London business had soared to a record high.
Chief executive Mark Lawrence said forward orders at the end of last month jumped to a new all-time record of £525m – £320m of which (2020: £257m) was already secured for 2022 with many other significant opportunities in TClarke’s bid pipeline.
He added: “Importantly, we are not experiencing any materials shortages that impact our ability to meet delivery of our projects.
“The board now expects revenue for the year ended 31 December 2022 to be ahead of market expectations at £410m.”
Lawrence said the technologies market was a major growth area for the business and was key to achieving its £500m revenue target.
He said: “It is therefore pleasing to report that the board now expects one third of group revenues to come from Technologies in 2022, up from under 15% in 2020.”
