Vieux Fort Water Supply Redevelopment Project
St. Lucia, W. I.
The Vieux Fort Water Supply Redevelopment Project is part of a list of several island wide water supply improvement projects with the specific objective of achieving a sustainable supply of potable water to all of the residents and businesses of Vieux Fort. Under the project contractors, Vinci Construction Grand Projects (S.A.S.), Amarna was sub-contracted to produce:
1.Civil engineering and structural design drawings and calculations for the building components of Grace and Beausejour Water Treatment Plants (WTP) sites

Volet River Crossing
St. Lucia, W. I.
The Volet Culvert Crossing, located in Micoud, is one of the critical culvert crossings along the East Coast Highway which connects Castries to Vieux Fort. In December 2013 Saint Lucia experienced the Christmas Eve Trough, which resulted in the extensive damage to the Volet Culvert Crossing.
As the Design Consultants for this project ACL’s role is to prepare preliminary designs for the suggested reinforced concrete culvert but also to present alternative options while comparing the cost benefit analysis for each option. Through preparation and/or analysis of topographic surveys/mapping, hydrological/hydraulic conditions and geotechnical conditions, preliminary designs for the initial box culvert were prepared, as well as for the alternative options of a composite arch bridge and right portal bridge. 

Rehabilitation of Primary and Secondary Roads,
St. Lucia, W. I.
In an effort to further improve Saint Lucia’s national road system The Ministry of Infrastructure, Ports Energy and Labour has initiated the largest single investment in roads being made by a government here in Saint Lucia. Valued at US$42 million, the Road Improvement and Maintenance Program (Phase IV) aims to deliver complete reconstruction of approximately 81km of roads in various communities for the benefit of citizens island-wide.
The government of Republic of China, Taiwan (ROCT) and government of Saint Lucia have engaged Overseas Engineering & Construction Cooperation (OECC) to undertake design and construction of the roads. They, in turn, have engaged Amarna as local sub-designers to provide complete detailed engineering designs for over 29m of road reconstruction located in Dennery, Micoud and Soufriere.

Feaibilith Study for the Development of the Millet Intake within the John Compton Dam Raw Water Supply System
St. Lucia, W. I.
The Millet Intake is a diversion dam constructed on an elevated tributary of the Millet River. Damage to the intake caused by Hurricane Tomas and siltation have cause variation/shortfall in the level of water it diverts from the Millet River to the Northern section of the island. In a effort to re-establish the Millet Intake as a primary source of raw water for the north of the island, the Water and Sewage Company (WASCO) has undertaken a feasibility study for the re-construction of the Millet Intake and the associated raw water line.
As local sub-consultants under R.J. Burnside out of Cananda, ACL’s role on this project included the preparation of a detailed topographical survey of the selected site for the intake structure; geotechnical investigation including borehole drilling; onsite local expertise and support for the location and design of the intake structure; and local administrative support.

St. Vincent Port Modernization Project
St. Vincent & the Grenadines, W.I.
The Government of St. Vincent and the Grenadine, under the execution of their Port Authority are currently undertaking the modernisation of their port facilities through the construction of a new cargo port in Kingstown. The proposed site for the Kingstown Port Extension runs along 600m of undeveloped coastline North-West of the existing Port facility starting from the fisherman’s jetty to ‘Bottom Town Beach’. The port will extend approximately 100mm from the shoreline adjacent to the central business district in Kingstown.
Under the helm of Sellhorn Ingenieurgesellschaft mbH, ACL’s role on this project was to provide geotechnical investigation: topographic survey; bathymetric survey; and traffic study of the marine area chosen for the future location of the New Kingstown Port in St. Vincent.
