The UK is aiming for carbon neutrality by 2050 and wants to accelerate the development of nuclear power. It has therefore approved the project to replicate Hinkley Point C on the Sizewell site. This project involves the construction of two EPR-type pressurized water reactors with a total capacity of 3.2 GW.

Thanks to their expertise on the Hinkley Point C power plant, Ingérop teams have been commissioned, under a framework agreement, to carry out the civil engineering studies for four buildings on the nuclear island, intended for tanks and hot laundry utilities, hot warehouse and decontamination workshop and intermediate level waste storage.

The scope of the studies is as follows:

• Global calculations (soil-structure interaction, finite element modeling, reinforcement maps),
• Local calculations (reinforcement sketches and detailing briefing packs),
• Production of 3D models (general arrangement and reinforcement).

By order of the Free State of Bavaria, the water management service of Donauwörth is implementing the flood retention basin on the Mindel to protect the town of Burgau. The basin has a retention capacity of 1.4 million m³. The implementation of the basin consists of a slightly curved dam embankment with a length of 1.5 km and a height of 6.0 m, as well as 4 multi-span dam structures for regulating the retention area. The flow rate is thus to be reduced from 135 m³/s to 65 m³/s. The adjacent railway line and the federal highway also constitute planning intersections.

Project overview

The Thames Barrier is one of the world’s largest and most prestigious moveable flood defence structures. It was designed by Rendel who also supervised the construction of one Europe’s largest civil engineering projects undertaken between 1975 and 1985. The Barrier protects London from North Sea surges which, when combined with high astronomic tides and heavy fluvial flows, could result in flooding over large areas to effectively take London out of action for up to six months.

The structure covers the entire width of the River Thames at Woolwich, with four primary openings of 61m to permit navigation and six subsidiary gated openings.

A novel feature is the 19m high, 3,400 tonne Rising Sector Gates (RSG’s) in the navigational openings, which lie in recessed sills in the river bed when not in use to allow unobstructed passage of river traffic through the Barrier. Each gate is pivoted and supported between concrete piers, which contain the operating machinery and control equipment, with primary controls located on the south bank.

All gates are designed to withstand a design surge differential head of 8.4m from the downstream side. When a flood threat is imminent, the gates are swung up through 90 degrees to a vertical position and form a continuous barrier across the river.

Initial Studies (1960’s)

Following the disastrous tidal flooding and loss of life in the Thames Estuary and east coast, studies were under taken to estimate the potential levels and frequency of tidal surges and the impact these could have on the Thames Estuary and London. Various schemes and locations were considered before Rendel recommended a unique form of structure – a Rising Sector Gate – located at Woolwich Reach, with several gates of differing sizes completing the closure of the 520m river width.

Design Phase (1970 – 1974)

In 1970 The Greater London Council, instructed Rendel to proceed with their recommendation and, given the uniqueness of the scheme, the design was accompanied by considerable research and development. The novel concept of the RSG’s had to be tested structurally and hydrodynamically. Rendel directed the testing at Imperial College London, and Manchester and Cambridge Universities. Design criteria were agreed between the Executing Agent and Consultants, based on the earlier studies and required the design to withstand a 1,000-return surge tide, covering the conditions pertaining to the year 2030. A key parameter in the design approach was to ensure unimpeded navigation of the river during construction.

The creation of a dry port, a Value-Added Logistics Centre (VALC) near the 6th October City, west of Cairo, to be connected by rail to the Port of El Dekhila Port and the Great Port of Alexandria (GPA) container hub. The VALC is planned to be the centre of a state-of-the-art facility which will combine all types of logistics/warehousing activities (refrigerated stores, bonded and non-bonded warehouses, etc.) It will allow the transfer of part of the container traffic transiting these two ports to the dry port for customs clearance and thus relieve congestion at these two existing ports and reduce other negative environmental and social externalities linked to the present movement of this traffic by road vehicles.

Services Provided by Rendel:

Traffic Review Study and Traffic Demand Study forecasting likely use of the dry port for several types of container traffic and likely throughput of containerised cargo transiting the dry port. Traffic Impact Study. Port Operations study within the Dry Port Area based on traffic forecasting, producing layouts of dry port appropriate cargo handling equipment with development cost estimates, including cost of civil construction, cargo handling equipment, manpower and maintenance.

Review of railway operations linking the two locations.

Abidjan Metro Line 1 is a surface train 37 km long spreading from North to South and crossing the Abidjan lagoon. The line will serve 20 new stations. 2 intermediate terminus stations will allow to operate the central section of the line with a double frequency.

Specificities

The layout uses a narrow urban corridor twinning with the freight SITARAIL line, which implied numerous retaining walls and overpasses.

The construction has been awarded to a consortium led by Bouygues TP under a PPP scheme.

The assignment consists in providing a layout study, then a Preliminary and a Detailed responding to the requirements of the Ministry of Transportation, and defining a bankable project for a PPP realization.

The program and the studies have been optimized to that purpose. For example, one intermediate step consisted in analyzing 3 various infrastructure scenarios, corresponding to 3 tariff scenarios and thus 3 passenger traffic scenarios.

Assignment

The full layout, civil works and stations were studied :

• Main track layout study, and its impact on SITARAIL infrastructures,
• Earthworks,
• Geotechnical studies,
• Hydraulic studies,
• Bridges : underpasses, overpasses, footbridges for public crossings and at stations,
• Stations (platforms, buildings, Civil works and systems integration).
