The awards, run in association with HW, will see winners and principal winners presented with prizes at December's glittering awards ceremony - a fixture in the landscape diary now recognised as the networking event of the year.
Multiple spin-offs for the winners include peer recognition of high achievement and a strong motivational spur to staff.
"Winning one of these awards offers a company great marketing opportunities, with the benefits lasting long beyond the ceremony," said a spokesman.
Judges this year will choose winners in around 15 categories. The adjudicators are Greg Allen, Michael Chance, Steve Roberts, Robin Templar Williams, Richard Barnard and John Melmore. Rigby Taylor is headline sponsor for the event.
The deadline for entries from full contractors/group members of BALI is 24 May. Registered designers, overseas businesses and affiliates have until 2 August. See www.baliawards.co.uk.
