ACES Regional Center of Excellence(RCE) for Pavement Studies and Evaluation has successfully completed an extensive study at the Dubai International Airport (DXB) to evaluate the pavement condition of the southern runway, its associated taxiways and general service equipment (GSE) roads around the airport facilities and concourses. The detailed scope of work, which was awarded to ACES RCE by Dar Al Handasah, included several highly specialized destructive and non-destructive evaluation methods. The non-destructive scope included visual inspection and documentation of the present condition and existing types of distresses, pavement condition index (PCI) evaluation, international roughness index (IRI) evaluation and Boeing bump index (BBI) evaluation using the laser roughness profiler. Furthermore, the pavement deflection, modulus of elasticity, modulus of subgrade and load transfer efficiency were non-destructively evaluated using the super heavy falling weight deflectometer (SH-FWD). Results of the above-mentioned tests were cross-checked and accompanied by destructive evaluation of the pavement by excavation of test pits, drilling of asphalt and concrete cores on rigid and flexible payment layers, and a thorough lab testing program was carried out to determine the physical and mechanical properties of the sampled materials. Being the world’s third and sixth busiest airport in terms of passenger and cargo traffic respectively, introduced an added layer of complexity during work completion. With only two operational runways, all sampling and field work had to be completed on taxiways with live aircraft traffic, and all sampling points (test pits and cores) required drilling, excavation, and reinstatement during very limited runway closure periods in close coordination with air traffic control.

ACES Jeddah has been awarded recently the geotechnical investigation works for Baha and Assir Housing project with a total area of 30 million square meters in the Assir and Baha regions of Saudi Arabia. The client is the Ministry of Housing and the consultant is Khatib & Alami. The project is part of the Saudi Government program to provide 500,000 housing units to middle class Saudi families and to meet the growing housing needs in various regions of the Kingdom. The aim of this investigation is to explore the subsurface conditions for the infrastructure detailed design works of Bisha site in Assir area, and the scope of work include 444 boreholes with depth ranging between 10 meters up to 20 meters below ground, 45 trial pits, 50 piezometer, 50 permeability tests and a wide range of laboratories tests.

ACES Khobar successfully completed recently the quality control works for the King Fahd Causeway Island Project in Khobar, Saudi Arabia. The King Fahd Causeway Island “A” Project is a project for dredging and reclamation of “Artificial Island A of King Fahd Causeway”, with a contract value of $78 million and a construction period of 18 months. It involves reclamation of 7 million cubic meters of material and foundation treatment of an artificial island covering an area of some 720,000 square meters, artificial island revetment construction and marina construction. ACES Khobar scope of work included technical support and guidance in site laboratory testing including rock testing( drop test, shape index, soundness, point load index, specific gravity, ten percent fine and aggregate impact value), concrete test, field testing( field CBR, DCPT) and soil testing. The owner of the project is King Fahd Causeway Authority, the consultant is Dar SSH International Consultant and the contractor is China Harbour Engineering Arabia Co. Ltd. (CHEAC).

ACES Dubai was recently awarded the pile testing work for the roads project ( R881/3C2 ) in Dubai, UAE. The project owner is the Roads and Transport Authority (RTA), the consultant is Parsons and the piling work is being completed by Universal Piling Company and Dutch Foundation. The objective of the project is to mitigate the traffic intensity on the Sheikh Zayed Road. The project is the continued extension of Al Asayel Street (D72) and First Al Khail Street (D86), as well as the updating improvement of Al Yalayis Street between Mohamed Bin Zayed Street and Sheikh Zayed Street. The total project value is estimated at AED 800 Million and is considered one of the largest infrastructure projects awarded from RTA in the past few years. ACES Dubai scope of work for pile testing in the project includes pile instrumentation testing for 41 piles, cross hole sonic testing and pile integrity testing for 858 piles, caliper logging of pile boreholes for 315 piles and static loading test for 83 piles.

ACES Jordan has recently completed the initial site investigation phase for the Red Sea - Dead Sea Pipeline Project in Jordan. The objective of the proposed project is to stabilize and control the alarming pace of water level drops in the Dead Sea by gravitationally flowing seawater from the Red Sea. The Dead Sea water level is falling at a rate of one meter per year and has dropped from 394m below sea level in the 1960s to 423m resulting in several environmental problems. The proposed project will include the construction of a 180 km pipeline engineered to carry up two billion cubic meters of seawater per year, and pumping stations to transfer substantial quantities of water from the Red Sea to the south area of the Dead Sea. ACES scope of work for the geotechnical investigation included the drilling of 18 boreholes to depths ranging from 8 to 20 meters below the existing ground surface, 25 test pits, field testing including SPT, permeability, field density, field CBR, soil electrical resistivity, and soaked plate load, in addition to intensive laboratory testing. The project was awarded by Dar Al-Handash. In 2009, ACES completed the subsurface investigation for the initial proposed design for the Red Sea – Dead Sea Pipeline Project. The geotechnical investigation scope of work included the drilling of 37 boreholes to depths ranging from 10 to 180 meters below the existing ground surface, 65 test pits, field testing including standpipe piezometer installation, permeability, and soil electrical resistivity, in addition to intensive laboratory testing. The project was awarded by Tractebel Engineering Coyne Et Bellier. ACES has previously completed geotechnical and site investigation work for other major projects in Jordan including Al-Abdali project, Queen Alia New Airport, Jordan Nuclear Power Plant, Saraya Al –Aqaba, Hilton Dead-Sea Hotel, Potash Dead-Sea Dikes 19 and 20 , to name a few.
