WYG has restructured its UK management team and reorganised its operations into two divisions.
The building and engineering consultant said the latest changes provide a “simplified structure”.
The UK operations will now be split into two divisions; planning, environment and transport; and management services/buildings and infrastructure.
They will be headed by Tim Holden and Clive Anderson.
The move effectively removes a layer of management, though its four other divisional leaders remain with the company.
WYG said the latest move will “position its senior management team to play a bigger role in growing the business and leading a more focused and joined up marketing strategy”.
Previously the firm’s operations were split into building and infrastructure; energy; management services; waste; environment; planning; transport.
The change comes after Glen Thorn was made head of WYG’s UK Region.
Mr Thorn said: “We have an opportunity to continue to create our own place in the consultancy market, one that is significantly different from the large engineering businesses with which we traditionally compare ourselves.
“I am looking forward to leading our UK teams into a new era for the company”.
Analysts expect the company to return to operating profit at its half year financial results later this week.
WYG employs more than 1,400 people and works across 40 countries. Formerly White Young Green, the firm saw extensive restructuring, with staff numbers down from 3,700 to 1,450 between 2008 and 2012.
Chief execuitve Paul Hamer told CN in August that significant restructuring is now in the past.
The firm has since put its Republic of Ireland businesses in liquidation, which employed 50 people but had 750 at its peak.
Its Northern Ireland division was also placed into liquidation, but then bought back by the firm, securing 90 jobs.
