ACES Carries out Bi-Directional Static Load Testing for Bridges and Overpasses at Bidbid Sur Road ACES Pile Testing and Instrumentation (PT&I) Regional Center of Excellence has completed an extensive pile testing and instrumentation program for the Bidbid Sur highway (Section 1) in Oman. The Bidbid Sur project consists of the expansion of a 75km section of a road from a single, two-lane carriageway to a four-lane dual carriageway highway and includes nine crossings with bridges, one underpass, four overpasses and a 50km service road. ACES scope of work consisted of 1,000 pile integrity tests, 580 cross-hole sonic tests, and 14 static load tests to a capacity of 700 tons. One of the main challenges faced by ACES was the difficulty in transporting static load blocks and beams due to the mountainous and rugged area along the roadside. As an alternative solution, the ACES team suggested utilizing bi-directional static load testing, which was conducted successfully at six locations (tested to a capacity ranging from 615 to 3,000 tons). The bi-directional test is an innovative method to test high capacity piles through hydraulically driven, sacrificial loading device installed within the foundation unit. As the load is applied to the device, it begins working in two directions; upward against upper side shear and downward against base resistance and lower side shear. ACES PT&I Center of Excellence is one of the pioneer centers in the region in pile testing and instrumentation and offers a wide array of technical services including but not limited to pile integrity, caliper logging, static load testing, high strain dynamic load testing, and bi-directional static load testing.

Arab Center for Engineering Studies (ACES) has been providing support in several capacities to the new American Society for Civil Engineers (ASCE) student chapter which was initiated at the University of Jordan in August 2015. Dr. Naeem Abdulhadi (Deputy Group CEO for Operations) is the practitioner advisor for the new chapter, whereas Prof. Samih Kakish from University of Jordan is the faculty advisor. ACES has sponsored the various activities carried out by the chapter and has organized seminars and field trips to the students. In addition, ACES is assisting in training and mentoring the students as well as providing internship opportunities during the summer breaks. Some of the activities carried out by the chapter include balsa wood bridge competition, treasure hunt, technical debates, engineer’s week events, field trips and seminars. “Our objective is to expose the students to practical issues and projects and to better connect the students at universities to the engineering industry and companies. We are engaging the Jordan Engineers Association, A/E Business Council and the main engineering companies in Jordan to prepare the student to enter the practical world through comprehensive trainings, internships, field trips, seminars, and personal interactions, among other initiatives” explained Dr. Naeem Abdulhadi.

ACES Jordan has recently completed the geotechnical investigation for the Wadi Araba Dams in Jordan. The Wadi Araba Dams are part of an integrated master plan launched by the Jordan Valley Authority (JVA) for developing the Wadi Araba area between the Southern Ghor and the Gulf of Aqaba, a 165km long and 9-40km wide area. The development projects include the construction of several storage dams that will benefit, renovate and revive water resources, agricultural activities, tourist and industrial sectors in the Southern desert area. The purpose of the geotechnical investigation was to assist in the dam type selection by assessing the foundation ground conditions, identifying the boundaries between the overburden soil deposits and rock formations, investigating the hydraulic properties of the dam sites, and identifying the suitability of the surround material for construction purposes. The ensuing investigation consisted of drilling a total of 16 boreholes, including two inclined boreholes, to depths ranging from 20m to 45m, hydraulic permeability testing of 29 falling head permeability tests and 39 Lugeon (packer) tests, and excavating 15 test pits including rock bulk samples. The field work was followed by a series of laboratory tests including direct shear testing for recovered soil samples, as well as chemical testing, soundness, Los Angeles Abrasion and petrography for the aggregate materials.

ACES Amman was recently awarded the geotechnical investigation for the second phase of design of the rehabilitation and reinstatement works of Dikes 19 and 20, in the Dead Sea, Jordan. The purpose of this investigation is to define the subsurface conditions in the study area in order to put the dikes back in operation after a sudden and catastrophic failure occurred in 2000. ACES Amman scope of work includes drilling of 30 boreholes and 14 Cone Penetration Tests (CPT) holes down to a depth of 50 meters, field testing (SPT and Permeability), installing standpipe piezometers, in addition to performing the necessary and applicable laboratory testing and geotechnical reporting. The client is Arab Potash Company and the consultant Dar Al-Hanadaseh.

ACES Dubai completed in 2015 the geotechnical and site investigation work for the prestigious Metro Red Line Connection to Expo 2020 Site. The proposed development aims to facilitate and support Dubai’s hosting of 2020 World EXPO. Roads & Transport (RTA) is developing a link between the existing Dubai Metro Line adjacent to Sheikh Zayed Road to EXPO 2020 near Al Maktoum International Airport. The connection will add up to 12 Km of track and as many as four new Metro Stations. ACES Dubai scope of work in this project includes drilling of( 8) boreholes up to a depth of 50.0m each, (11) boreholes up to 30.0m each; excavation of (17) trial pits was carried out at the specified locations up to a depth of 2.0m below the existing ground level; conducting (14) falling head permeability tests and (11) packer permeability in specified boreholes within the project site; installation of (19) standpipe piezometers in specified boreholes within the project site (one piezometer in each borehole); performing the required laboratory tests on soil, rock and groundwater samples; and preparing factual report as per the project requirements. The client name is M/S Roads & Transport Authority (RTA)-Dubai and the consultant Parsons International.
