Atkins provides services on Geotechnical Inspection of slopes and retaining walls including both Annual Routine Maintenance Inspection and Engineering Inspection. Inspections are carried out by professional staff to identify potential hazards and to identify maintenance works required to ensure the slope features' proper functioning. Recommendations for emergency stability improvement works and needs for stability study will be made from the inspection and desktop studies. We have significant experience on such kind of works for private owners, estate management companies and government authorities.

Atkins provides services to private owners, where Dangerous Hillside (DH) Orders are issued by Buildings Department. We can investigate the stability of the slopes and/or retaining wall and advise on whether they meet the current legislation requirements. We have lots of experience in designing cost effective and economic upgrading work to achieve acceptable stability requirements and hence to lift the DH Orders.
