4 The D1 project at Belfast Harbour, the UK s first purpose-built offshore wind logistics facility, involved the construction of a new 500m quay wall structure and a deep water berth. The quay wall was constructed over both land and water, utilising 32m long, 1.6m diameter tubular piles in combination with 22m long PU22 sheet piles. The combi-wall was tied back to a reinforced concrete anchor beam, supported on 367 raking tubes. These tubes were 30m long and 760mm diameter and were anchored to the rock. A total of 30,000m³ of concrete was used during the construction of the relieving slab which is supported on 780 CFA piles of diameter 750mm. Works also included the dredging of 600,000m³ of material for the new deep water berth and approaches and its disposal at sea. An additional 20,000m³ of contaminated dredged material was treated on site prior to disposal. Approximately 150,000T of rock armour was placed beside the quay wall as protection for the seabed. The contract also entailed the development of 50 acres of hinterland. A total of 900,000m² of geotextile and 1,000,000T of aggregate was used in the construction of 200,000m² of heavy duty unbound pavement for the hinterland. General services were also installed to supply the future renewables hub. The D1 project - the largest ever undertaken in the 400 year history of Belfast Harbour was completed in just over one year.

5 Page 8 & 9 Mersey Docks and Harbour Co. Ltd 11 Million Seaforth Passage The existing Seaforth Passage gives access for cargo and ferry vessels into the Royal Seaforth Dock within the Port of Liverpool. Due to a proposed increase in the size of vessel using the port, it has become necessary to widen the passage by approximately 20m. The dock structure was built in the 1970s and comprises reinforced concrete diaphragm walls approximately 38m apart and 100m long. These walls house steel sector gates which were designed to close the passage between Gladstone and Royal Seaforth docks. Extending underneath the passage, there is a 3m diameter siphon connecting the Liverpool storm drainage system with an existing outfall. There are also link ducts containing the HV, LV, communications and water supplies essential for the operation for the port. The widening project included installation of a new piled quay wall behind the existing western diaphragm wall. The new quay was a combi wall with sheet pile infills tied to a sheetpile anchor wall. A permanent cofferdam now provides access to the existing siphon for its extension beyond the line of the combi wall. A new, prefabricated steel 1m diameter U-Tube extends between service culverts on the eastern and western sides, diverting the existing services around the works area. Floating plant was used to demolish the western diaphragm wall and the 420T western sector gate. The gate was then cut into sections using explosives placed by divers and lifted to shore for recycling. All works were completed whilst maintaining shipping through the passage.

6 Farrans was contracted by EDF Energy Nuclear Generation Ltd to carry out repairs to the cooling water outfall structure of Heysham No.1 at the licensed nuclear site at Heysham. Page 10 & 11 EDF Energy Nuclear Generation Ltd 2.6 Million The cooling water is discharged from the cooling water culvert into a channel predominantly formed by two parallel rows of frodingham steel sheet piles which run westwards to the deep water channel. Generally, the condition of the structure had continued to deteriorate due to corrosion as would be expected for a steel structure in a marine environment. In numerous locations, there were areas of suspected Microbially Induced Corrosion (MIC) which had led to significantly higher corrosion rates. Heysham Cooling Water Outfall During 2008 and 2012, a significant number of the sheet piles failed above berm level, in addition to the formation of less significant holes and leaks. The repairs which Farrans undertook involved the installation of replacement sheet piles along sections of the structure which were failing. New piles were landed next to the existing piles to form a box. These were subsequently bolted together and sealed using concrete. The piles were driven into place from a jack-up barge and, in order to maximise productivity, works were being carried out 24 hours a day. The project was completed on budget, to programme and the satisfaction of EDF Energy Nuclear Generation Ltd.

7 Page 12 & 13 Forth Ports 2.4 Million Granton Harbour Wall The Granton Harbour Wall development was part of a multi-site regeneration of some of Edinburgh s industrial heartland. The Harbour Wall was one of a number of projects successfully carried out by Farrans as part of the long-running multi-agency scheme. The new wall was required to reclaim a new development footprint from the existing sheltered anchorage for small boats at Granton Harbour. At 200m long, the quay wall was constructed of new sheet piles shipped directly to the site, handled and installed from the Farrans barge, the Claude Monique. The front wall is anchored by tie rods to a new anchor wall. As part of our bulk earthworks exercise, we worked with our to identify local fill sources and test the material, ensuring its viability for use as marine structural fill.

8 The Montrose Port Authority Deep Water Berth Project involved the redevelopment of the berthing and cargo handling areas at the South Quay. It included the removal of the existing collapsed quay wall and reconstruction of 230m of heavy duty combi wall and service bases for the offshore oil and gas industry. Page 14 & 15 Montrose Port Authority 8 Million The existing quay walls at Berths 16 and 17 had collapsed and the contract required their removal from the seabed prior to the installation of the new quay wall. We used underwater drilling and blasting techniques to remove the collapsed sections before building the new quay wall as a combi-wall structure. The concrete deck was strengthened by a matrix of hard driven concrete piles within an area specifically designated for heavy lift purposes. Montrose Deep Water Berth Utilities and bunkers on the quayside were also constructed and included water, gas, oil and lighting. To provide a facility for deep draft vessels, a total of 27,000m³ of material was dredged from the berth. The dredged material included estuarine alluvium and boulder clay deposits and was safely transported to a licensed disposal site at sea.

9 Page 16 & 17 Pointhouse Quay Glasgow City Council 6 Million Situated at the mouth of the River Kelvin, Pointhouse Quay was part of Glasgow s Masterplan to rejuvenate the dockland area. The quay is now the site of the new Transport Museum for Scotland, as well as the permanent berth for the Tall Ship Glenlee. Works involved installing a steel piled combi-wall anchored back to anchor blocks. Working from land, we installed 106 tubular piles at a raking angle. These supported the anchor blocks which were then secured by a rock anchor and drilled concentrically down the raked pile. The anchor block was then securely fastened to the rock, some 30m below the surface. Due to the size of the tubes on the combi-wall, the support formwork for the cope needed to be specially designed. The support mechanism was manufactured by welders and tested within our plant yard in Belfast. This system proved to be very effective and when stripped, could be used repeatedly for cope construction.

10 Page 18 & 19 Montrose Port Authority 5.7 Million Montrose Berth 6 Renewal This project involved the design and construction of a new quay structure at Berth 6, Montrose Port, to upgrade the existing berth. In order to ensure the existing quay was fully operational during the course of the project, the works were designed to be carried out in two phases. A 180m long combi wall was constructed at the front face of the quay, utilising tubular and sheet piles. The tubular piles were a combination of 1.2m and 1.4m diameter piles, 29m in length, with AZ18 sheet pile infills. The front wall was connected to a sheet piled anchor wall, 180m long, using tie rods. The quay deck structure covers an area of 4,800m 2. The slab structure is supported on precast piles and incorporates heavy lift areas. A new drainage system was installed on the quay, including a drainage channel, manholes and outfalls for surface water drainage. In order to facilitate the service requirements for the new quay structure, we provided a service trench, with special access covers and ducting. The contract also included the installation of new quay furniture including ladders, fenders, bollards, etc. In addition to these works, 8000m 3 of material was dredged from the channel in front of the quay to deepen the berthing pocket.

11 Page 20 & 21 Warrenpoint Harbour Development Warrenpoint Harbour Authorities 6.8 Million The Warrenpoint Harbour Development project responded to the need to deepen the existing main berthing facility at Warrenpoint Harbour which is situated on the mouth of the Newry River. As part of this design and build appointment, we installed 320m of combination piled wall along berths 4 and 5. This deepened the harbour area by 2m, allowing large vessels to use the dock facilities. The final work on this scheme included the construction of a new 110m long rock bund breakwater which runs from the existing custom house quay. The electrical services and water supply on the quayside were also upgraded, along with the replacement of all the quay furniture.

15 The Belfast Tunnel is a stormwater management sewer built by Farrans in one of our most successful strategic joint ventures. It is 9.4km in length, with tunnels ranging in diameter from 1.5m to 4.0m and connected by overflow weirs to the existing Victorian network. Working at depths of up to 35m below the city streets, the larger tunnels were constructed using an Earth Pressure Balance tunnel boring machine and the smaller bores were formed by pipejacking. We constructed 19 shafts for access to the tunnel with diameters up to 12.5m. We also worked with local communities to ensure we made a positive contribution by providing walking buses to guide schoolchildren safely through our temporary diversions. We controlled noise using acoustic enclosures and showcased the project on hoardings and through community participation projects. The downstream Terminal Pumping Station (TPS) is one of the most significant aspects of the scheme. It houses stormwater pumps with a capacity of 16,000 l/sec in a 38m diameter shaft constructed to a depth of 40m in very challenging ground conditions. We used a number of highly specialised techniques to construct the TPS, including diaphragm walling and sprayed concrete excavation support to get to base level and curved jump formwork to cast the walls. The pumps discharge to an outfall and diffuser at the adjacent sea shore. Page 16 & 17 Belfast Sewers The Belfast Tunnel N. Ireland Water 120 Million
