QUAY OPTIONEERING FOR NEW BULK TERMINAL PHASE II IN AFRICA
Trent Port Services Pte Ltd (Trent Global) was approached to conduct a quay optioneering exercise to determine the most suitable quay solution for Phase 2 of a Bulk Terminal Development in Africa.
Trent Global subsequently appointed us to collaborate on the design consultancy to carry out the “Quay Optioneering Exercise” for Phase 2 and to identify the most suitable engineering solution for the proposed Berth 2. Phase 2 involves the development of a 200 x 35-meter berth, which is an extension of the ongoing construction at the port.
Eka Infra’s scope of work included at a broad level the following activities considering the above are as follows:
- Review all available data and provide a Gap Analysis report, highlighting if there is any additional information necessary
- Design Basis Document for the Phase 2 of project, with consideration Phase 2 existing basis of design documents
- Maximum of three suitable quay structural options to be developed for selection with pros/cons, based key criteria related to site conditions, engineering, constructability, operations, costs, schedule, maintenance
- Various option for soil retaining soil stability beside berth to be developed in different options for shore and land side protection. Option to be included but not limited to different types of sheet pile, tie back anchor wall or any other types of retaining wall, revetment, and slope protection method
- Option engineering of berth to be performed by ultimate limit state in accordance with BS:6349-1-2:2016 for persistent, transient, and accidental design situation. In addition to limit state, serviceability limit state design to be performed for characteristics, frequent and quasi permanent situations
- Concept drawings for three maximum suitable options to be provided
- Construction CAPEX estimations for the options studied to be provided with sufficient detail to allow for selection review, with the three maximum options having a level of +30% to -20% (AACE Class 4 accuracy)
- A project schedule (Level 1) and high-level construction methodology for all three options to be provided
- Undertake workshops with the client to discuss and present the options and considerations
- Final Optioneering Report and Presentation with recommendation of preferred quay option to be submitted
A team of head office professionals and associates of Eka Infra comprising of civil, geotechnical, structural engineers and administrative staff with experience in the field of design consultancy assisted in ensuring that the works have been completed in line with the standards prescribed by the Contract in November 2021.
