Workers will return to the Colwyn Bay Pier site tomorrow.
Borehole investigation work will be carried out on the seawall and the upper retaining wall on the site of the former pier in Colwyn Bay tomorrow and Friday.
The testing is part of the preparation for the construction of a new truncated pier, which was one of the listed building conditions placed on Conwy County Borough Council (CCBC).
The investigation work aims to determine the profile of the rear face of the wall and foundation depths.
The contractor taking on the work will be Colin Jones (Rock Engineering) Ltd.
Dismantling of the pier, which has stood on the Colwyn Bay promenade for more than 100 years, was completed in May.
Work on the construction of a new truncated pier could begin as early as spring 2019 after a designer was named to draw plans in July.
