Project ile soleil

Ile Soleil is 123,000 square metres of reclaimed island at Anse Aux Pins, in the eastern district of the main island of Mahé. The new island is mainly designated for residential development along with some commercial plots.

This month sees the commencement of the ground infrastructure work including; the provisions of water, electricity, roads, pavements, drains, street lights, sewage, telecommunication ducts, bridges, added reclamation work, public parking and garden spaces.

United Concrete Products Seychelles (UCPS) won the contract to carry out these major works alongside engineering company GIBB (Seychelles). The infrastructure works are due to be completed by December 2015.

Micro-Piling Castor Road

In July 2016, the technical expertise of UCPS was requested for foundation solutions for a new apartment building project. The site is situated along Castor Road in Victoria. Due to the complexity of the sub-stratum, revealed in the Geotechnical Investigation, and the very tricky site accessibility, UCPS geotechnical and piling department came out with a design and build micro-pile foundation solution.

The design being approved by the Client’s Engineer and the Government Authorities, UCPS mobilized on the site and launched this first ever micro-piling foundation project in the Seychelles. To be able to drill and cast effectively the 44 designed micro-piles, our technical team adopted the ODEX down the Hole Hammer drilling method. Our 15 bars Compressor was thus also mobilized together with our Hanjin versatile D&B 8B Drilling Rig.

Prior to the effective start of the micro-piles drilling, a test pile was drilled and casted following a series of grout-mix design in our Laboratory of Providence. An initial Static Load Test was performed successfully and the green light was then given for the drilling of the 44 piles. At the end of the drilling and casting, a second Static Load Test was performed to confirm the effective strength of the piles.

Equipment Used for the Project

Anonyme Marina

Client: Anonyme Estates Ltd

Duration: 18 Months

Description: Construction of Marina

Construction of Cold Rooms and Fish Processing Factory for CCCS at Ile du Port, Mahé, Seychelles

The Central Common Cold Store (CCCS), the project consists of the construction of steel superstructure building of about 12,200m² resting on piled foundations to house cold rooms, sorting areas, fish processing factory and offices with all associated infrastructures. UCPS (Main Contract) has built all the civil works for the project and the steel work.

Part of UCPS scope of work is Coordinating the works of all the nominated sub-contractors (Site clearance and removal of trees, steelworks, refrigeration, cold-room paneling & refrigeration and hybrid power (generators & photovoltaic system).

La Digue Port Extension

The new design of La passe port extension at La digue will comprise passenger ferry, handling cargo, and landing craft slipway.

The duration of the project is 12 months starting from March 2022 to March 2023 for the Seychelles Ports Authority.

This project concern itself with the construction of a 128m long*6.95m wide z type sheet pile quay.

The existing basin will be dredged -3.00m ACD and to construct a new structure along the shoreline of the basin of La passe harbor. under the supervision of Seychelles port authority.

The port project helps La digue to upgrade and modernize the facility by deepening the harbor and increasing the berthing space by converting the present retaining wall next to the passenger terminal building for berthing purposes.

La Digue Port Extension Details

Dredging of existing sea basin to -3.00 ACD for an area of 6640m2.
Construction of Breakwater to keep the basin calm. The Breakwater is 83m long* 19m wide, which consist of rocks size varying from 700mm to 1200mm, from UCPS quarry.
Relocation of existing main electric cable passing of 200 meter long through the sea.
Sheet pile preparation - Sand blasting and applying primer and marine final coat paint before driving the piles.
