Rossaveal Deep Harbour

/in

Specialist offshore engineering and design consultancy, Gavin & Doherty Geosolutions Ltd (GDG), with their specialist dredging sub consultants, Anthony D Bates Partnership (ADBP), have been appointed by the Department of Agriculture, Food and the Marine (DAFM) to undertake the detailed design, tender and construction phases of the Rossaveel Deep Water Quay Development, at Rossaveel Fishery Harbour Centre (FHC), Co. Galway.

Rossaveel FHC is located on the north-east shore of Cashla Bay, approximately 40km west of Galway city, serving the fishing fleets that operate off the coast of Galway. The existing harbour at Rossaveel is constrained, as no deep-water facilities are currently available to accommodate modern fishing vessels, which continue to increase in size as the industry trends towards larger and more sophisticated boats. To address this, the construction of a new 200m long quay and associated dredging to provide -10m CD on berth (Chart Datum) and -7m CD in the navigation, has been agreed. A reclamation area will also be constructed directly behind the quay, which will provide connectivity from the quay to the existing onshore facilities at the harbour. The development of the harbour infrastructure will attract additional vessel activity and therefore create local employment opportunities in rural Ireland.

Project Objectives/ Outcomes

The UAV survey was undertaken by our Specialist Engineering Services (SES) team due to its prominent central London location and the requirement to fly as close to the building as possible. By undertaking a comprehensive UAV flight at close range (in line with all necessary UAV legislation and OH&S requirements), high-resolution imagery could be collated and inspected by our in-house Building Surveying team to provide a detailed Schedule of Condition Report.

In addition, the survey was undertaken to produce a full, accurate, and detailed scan-to-BIM model of the building facades in Autodesk Revit. Undertaken by the Digital Engineering team, the modelling was to be used by the architect, lighting designer, and various other project stakeholders to plan and refurbish the building.

Our Role:

Murphy Geospatial was commissioned to undertake various geospatial services at UK House, a landmark heritage building on the North side of Oxford Street, London.

The primary brief of the project was to undertake a UAV/drone survey of the building roof and facades for the dual purpose of condition reporting and accurate as-built BIM modelling.

Results:

By federating and updating the client’s existing survey and design information into a common BIM environment, Murphy Geospatial provided a singular BIM model of the building externals for all stakeholders to work from.

Regent’s Crescent

Services (Technical Disciplines)

The task of reconstructing John Nash’s Regent’s Crescent without damaging it’s Grade 1 listed façade or the Jubilee Line tunnels running just below presented many challenges. Management of those challenges was achieved, in part, through insight from a unique monitoring programme built around Senceive remote monitoring technology in the hands of experts from Murphy Geospatial. The bespoke solution enabled ground risk and impact on third parties to be measured and managed in a way that was safe, cost-effective and reliable.

Built in 1820, Regent’s Crescent is a prime example of Regency architecture and proposals to demolish and re-build the mixture of properties behind its iconic facade to deliver 83 high-end apartments required a robust monitoring plan. With the redevelopment including excavation of a full-footprint basement, safeguarding the tube tunnels was a fundamental part of that plan.

Established methods to monitor convergence and divergence in the tunnels including manual measurement and automated total stations were rejected because of drawbacks including the need for frequent access, power supply, extensive cabling and cost.

A total of 250 tilt nodes were installed in sets of five around the tunnel intrados, providing geographically remote stakeholders with virtually realtime insight into movement within the zone of influence. By establishing that the magnitude of movement caused by the construction activity above the tunnels was within predicted safe levels the monitoring helped to keep the construction programme on track and to satisfy third parties including London Underground and other property owners that their assets were not under threat.

Project Objectives/ Outcomes

The installation and monitoring of the tunnels took place over 5 years approximately. With the completion of Regent’s Crescent development last year in 2020. Murphy Geospatial delivered final monitoring reports to London Underground prior to removing the kit in 2020. Ongoing analysis of the data continues to get a better understanding on how tunnels of this type behave when put under stress from above.

Our Role

Monitor movement of London Underground tunnels to reduce costs and risk during the demolition and construction works.

Project Objectives/ Outcomes

The Limestone blend provided the visual effect required to replicate the tones of natural cobble stones but at a fraction of the cost.  The paving provided a durable paving product that can accommodate light traffic, parking and turning areas and requires minimum maintenance or protection from the elements

Our Role

To provide a functional and aesthetically pleasing courtyard to allow a very modern style house to nestle into a traditional rural setting

The courtyard would need to reflect the various hues of traditional cobble stones to portray the ambiance of a traditional rural courtyard.

The courtyard needed to reflect a variance in pattern and lines to create a canvas to enhance the clean lines of the modern home.

The product would have to be robust to accommodate pedestrian and vehicular traffic.

Roadstone supplied 450 m² of dual size, 60mm Limestone Blend Thomond Paving and 10m² of 60mm Verona Midnight Setts to this modern dwelling.

Roadstone also supplied 50 tonnes of laying grit for the paving and 200 kgs of granite sand in 20kg bags, to joint the paving. All the materials were supplied locally from Roadstone’s paving plant in Gooig, Co. Limerick

The Thomond Limestone Blend was laid as the body of the paved surface with the Verona Midnight Setts being used in a double row as an inset border. The paving was laid on 6mm grit and jointed with a kiln dried white granite sand which was sympathetic to the paving colour.

The paving contractor then sealed the paving, using a liquid sealer, in order to set the jointing sand, enhance the colours and provide extra protection from the environment.

Design and Build

Our Role:

Mincon’s patented Spiral Flush technology recently played a key role in a Skanska-led project to modify a rail junction called the Harold Interlocking – the busiest rail junction in North America.

The Harold Interlocking primarily serves Amtrak and the Long Island Rail Road (LIRR), but also supports train movement for New Jersey Transit and the New York and Atlantic Railroad.

Skanska’s task was to design and build a Support of Excavation (SOE) for the construction of a 200-foot-long (61 metres) concrete cut-and-cover structure that connected a bored tunnel to a 600-foot-long (183 metres) open-approach structure.

The key structural element chosen for the solution was a “mini” soldier pile measuring 18-inches (457mm) in diameter, but the nature of the site presented multiple challenges.

The first challenge was the glacial till, which contains nested cobbles and boulders in the subsurface that can be hard to drill through.

Second is the restrictions placed by the surrounding rail infrastructure, which eliminated the use of large drilling rigs due to the presence of overhead obstructions while also eliminating the use of impact and vibratory methods due to settlement concerns.

The drilling site was also surrounded by active rail tracks, which meant that equipment had to be delivered by train during rail off-hours, further limiting equipment size.

The site wasn’t suitable for using a conventional DTH systems due to the risk of damage to the rail infrastructure from flushing during drilling.

Mincon’s Spiral Flush systems offer a unique air control feature that entirely contains flushed air within the casing, avoiding disruption to the surrounding soil and nearby foundations.

The Mincon DTH hammer used for this project was attached to a modified excavator that was equipped with a drill mast and hammer controls using an excavator-mounted drilling attachment.

By partnering with Mincon, Skanska was able to overcome traditional objections to using air drilling near rail infrastructure, a practice banned by most rail agencies.

“The work was completed on time and on budget without any major issues,” concluded Skanska in its article. “Teaming with specialty equipment and tooling suppliers resulted in a site-specific drilling system that overcame the challenges presented by a very difficult site.”

Our Role:

The Heathrow Expansion Programme is a £14bn project to construct a third runway, taxiways linking it to the rest of the airport complex, a new terminal building and satellite, additional stand areas, new airport gateways, carparks and other associated infrastructure. It will involve re-routing the M25, diversion of rivers and substantial earthworks to achieve.

The ByrneLooby team were appointed to provide specialist landfill permitting advice in relation to the part excavation of the three existing permitted landfills and to prepare permit applications for four new landfills. To support the permit applications ByrneLooby designed the remedial works, the new landfills and carried out the associated environmental risk assessments. Our role in this project was wide-ranging and multidisciplinary including earthworks design, site investigation support, hydrogeological risk assessments, stability risk assessments, air quality assessment, design of landfill gas, leachate and odour control systems, environmental monitoring, regulatory compliance and advice on landfill tax.

ByrneLooby’s primary role was to secure advance Environment Agency approval of the proposed works in advance of the project moving into the construction phase. This required the preparation of seven full permit applications, including three to allow the existing MSW landfills to be partly excavated and remediated and for four new engineered containment landfills to be developed alongside the proposed new runway. The new runway is to be constructed over the top of the existing three landfills posing some complex remediation and foundation design issues. The existing leachate and landfill gas control systems will be replaced and a new capping system installed. The four new landfills are to be constructed to EU/UK standards and were designed to take account of their close proximity to a working airfield with associated access restrictions.

The project includes the design and construction of 3.8km of new carriageway, a 256m long five span steel viaduct bridge and 6 no. culvert structures.

Our Role:

The A737 Dalry Bypass involves the construction of a new off-line bypass to the east of the town of Dalry and associated junctions to connect to the existing A737 Trunk Road. The project includes the Design, construction and maintenance of the scheme including:

  • Approximately 3.8km of new carriageway comprising 2.45km of Wide Single 2 + 1 layout with overtaking lanes in opposing directions & 1.35km of single carriageway layout including the provision of a differential acceleration lane (DAL).
  • A five span steel viaduct bringing the mainline across the River Garnock floodplain and Glasgow to Ayr Railway line;
  • Blair Road overbridge a single span concrete overbridge bringing Blair road over the mainline;
  • One farm accommodation Underpass bringing a private access track beneath the mainline;
  • Mine consolidation works (grouting works);
  • 6 No. culvert structures to accommodate watercourses;
  • 2 No. Mammal underpasses adjacent to the culverts on the Coalheughglen Burn;

FT were responsible for the design of all structures on the scheme including the River Garnock Viaduct a 256m long viaduct over the River Garnock floodplain and adjacent Glasgow to Ayr Railway line.

The structure is a 5 span, weathering steel ladder deck bridge with precast concrete deck and piled in-situ concrete abutments and piers.

The steelwork for the bridge was assembled on the west embankment and push launched into place due to difficult access conditions between the river and railway. FT carried out the temporary works launch study to assess the impact on the bridge steelwork along with the load and deflection analysis for the temporary bearings, launch nose and tail design. Deflections during the launch over the railway span was particularly critical due to railway overhead electrical lines.

Precast concrete deck panels were designed to support a 40 Tonne crawler crane allowing the panels to be placed from deck level and then to support the crane for placement of adjacent panels. Precise detailing of the panels was essential to ensure that protruding reinforcement fitted precisely with adjacent panels and shear studs from the deck steelwork.

Scour protection measures for intermediate support columns within the floodplain were also required as part of the design.

Our Role:

J B Barry was commissioned by  to carry out a series of Road Safety Audits for the Main Design for Heavy Maintenance of Sections from the third year of the Serbian Road Rehabilitation and Safety Project (RRSP), which is supported by the World Bank, European Investment Bank, and European Bank for Reconstruction and Development. The project forms parts of the Government of Serbia’s National State Road Network Rehabilitation Program.

The Road Safety Audit work involved 12 schemes totalling 220 km of IA, IB and IIA class roads, located throughout Serbia. These roads included the IA-1 and IA-3 motorways which provide key strategic linkages between Belgrade, the rest of the country and the borders with Hungary, FYROM (Macedonia) and Croatia. The audits were undertaken in accordance with the PIARC publication “Road Safety Audit Guidelines for Safety Checks of New Road Projects” (2011), with the final audit report recently completed and delivered.

The team used role play to consider how all road users, including pedestrians, cyclists, motorists and visual- and mobility-impaired people, will cope in every condition. This included driving the routes during day-time and night-time, taking photographs and videos and drawing on our experience of undertaking Road Safety Inspections, Road User Audits and Accessibility and Disability Audits as necessary. Our audit team subsequently made recommendations on measures to mitigate any potential safety issues identified.

The RRSP will improve the conditions of the state road network as well as increasing safety for all road users and we’re delighted to have worked with Roads of Serbia, who were a very proactive and engaging client, on this project.
