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.
