King Abdullah Financial District – Ahlamana

OVERVIEW
Langan provided geotechnical engineering services for a mixed-use residential, office, and retail building located within the southern portion of the King Abdullah Financial District. Ahlamana consists of two structures, a 26-story (105 meter) residential tower and a 15-story (78 meter) office tower. Four basement levels are planned for about two-thirds of the parcel and a fifth basement level for the remainder of the parcel. The total footprint for the location is approximately 5,700 square meters. Langan’s subsurface investigation observed significant rock fracturing during drilling. Additional services included calculations and recommendations for permanent control of groundwater, a seismic evaluation, backfill and compaction, and a site-specific investigation to better understand conditions at the site.
