Commencement: March 2008

Design and supervision of geotechnical works involving earth retaining elements for the perimeter of a major commercial development of Alf Mizzi & Sons Group. The site is located within Mriehel, Malta and incorporates a three storey excavation within clay material. A combination of laterally loaded piles and mass retaining perimeter walls are being utilised to retain an existing adjoining building and perimeter road.

iAS was commissioned to prepare the geology, geomorphology and hydrology baseline studies for the EIA process for this project. This project is being carried out in two stages – a geotechnical desk study and site survey of the terrain around the Citadel was first conducted, resulting in the development of a conceptual ground model on which the borehole investigation was designed and commissioned.  The second stage, currently in progress, consists of the analysis of the retrieved cores, laboratory tests and numerical modelling of the existing and proposed slope profiles to determine the stability of the clay slopes and overlying historic structures.

The sewage treatment plant, currently under construction, consists of a series of reinforced concrete tanks and ancillary structures built on a sloping site on relatively weak rock.  iAS was involved during the excavations of this project,  when a clay layer was encountered that was much softer than expected.  A detailed site investigation and laboratory testing programme was carried out under the supervision of iAS to determine the load-bearing and settlement characteristics of the subgrade. The adequacy of the proposed foundations was assessed in close collaboration with the structural engineers of the project.

Client: Malta Freeport Corporation

iAS has prepared a geotechnical desk study of previous site investigations carried out within the Freeport area.  Borehole records and laboratory test results from the various investigations conducted since inception of the current terminal were analysed with the purpose of creating a conceptual ground model for the proposed extensions.  This model was used to design a site investigation to BS 5930 within seabed sediments and rock formations, specific to the project area. iAS prepared specifications for further borehole drilling, in-situ testing, retrieval of disturbed and undisturbed samples, and for laboratory testing to BS1377 and Eurocode 7. The ground model was also used to develop scheme proposals for the quay structures.
