In Hampshire and the Isle of Wight, a quarter of construction employees are aged 55 and over. An estimated 12,000 new recruits are required every year to meet forecast growth.
In response, businesses in the sector are being encouraged to exhibit at the Construction and Built Environment Skills Festival on 13 February at Southampton's Rose Bowl.
Designed to give 14 - 24 year olds a taste of career opportunities in construction and the built environment, the 'SkillsFest' will brings together all areas of the industry, from architecture and civil engineering to vocational courses such as carpentry and brick laying.
The event, is funded by the South East England Development Agency and the Learning Skills Council, and has been organised by Southampton and Southwest Hampshire's Education Business Partnership, Solent Skill Quest.
Chief executive Angela Wright said: “Hampshire is the second wealthiest county in the UK and construction is at the core of its continued development and success.
"Major developments springing up in towns and cities across the region are testimony to the area's growth and progress. The Construction SkillsFest is an important tool in ensuring that this growth isn't affected by a shortfall in qualified professionals, now or in the future.”
