  • Design
  • Risk Assessment
  • Site Investigation

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.

Services (Technical Disciplines):

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.

Services (Technical Disciplines):

  • Full 3D laser scan of the site at near project completion status.
  • Re-modelling of client architectural and structural models in Autodesk Revit.
  • Federation of numerous sub-consultant MEP as-built models and clash detection of all Architectural, Structural, and MEP elements.
  • Verification and checking of sub-consultant MEP models for accuracy and the reporting of all discrepancies utilising point-cloud dataset.

Our Role:

To provide an accurate model of the existing building and to federate all MEP models into an accurate and singular Revit model deliverable for the end client.

The challenges:

The client’s existing architectural and structural models of the building were supplied in ArchiCAD software; whilst the project deliverable to the end client was required in Autodesk Revit. Therefore, remodelling was required for the architecture and structure model to be supplied native to Autodesk Revit.

Laser scanning of the site was undertaken near project completion; meaning the majority of MEP and internal fit-out was in place at the time of the survey. Much effort was required to ensure as full data coverage as possible.

Our work:

A full 3D laser scan of the building and all installed MEP elements, including the use of an elevated tripod in order to capture as full coverage of ceiling level MEP as possible.

Remodelling of building Architecture and Structure in Autodesk Revit using both the existing model and 3D point-cloud datasets.

Federation of sub-consultant MEP models and alignments of all models to the correct site survey control grid and datum.

Clash detection of MEP and Architecture and Structure models as well as the reporting of all identified clashes to the tolerances outlined in the project’s BIM Execution Plan (BEP).

Manual verification of MEP models against 3D point-cloud data and utilisation of Autodesk Navisworks to highlight all discrepancies in the form of saved viewpoints and associated descriptive comments.

Numerous iterations of verification were undertaken following consultant model amendments and reporting on the ongoing accuracy of the supplied models through to project completion.

Our team:

x3 person laser-scan site team for the capture of a comprehensive 3D point-cloud dataset.

x4 BIM technicians for the production of an Architectural or Structural Revit model, MEP model federation, and all clash-detection and verification work.

Results:

End-client received a fully federated and verified Revit model containing all Architecture, Structure, and MEP. Discrepancies contained within the MEP models, were reported to the client and amended prior to the final delivery to the end client.

Date:

2019-2021

Business Sectors: 

Civil Infrastructure

Services (Technical Disciplines):

  • Subsurface Investigation
  • Topographical Surveys

Our Role:

Murphy Geospatial successfully delivered this large contract for the HS2 project, which will increase rail capacity and connectivity across the country, connecting London, the West Midlands, Manchester and Leeds.

The brief was to support one of HS2’s principal contractors, Skanska Costain STRABAG Joint Venture (SCS JV), which is delivering the 26.4km London section of HS2’s journey from West Ruislip to its southern terminus in Euston.

The project required topographic and utility surveys to help the design of utility diversions needed for the new railway line’s construction. The area of survey is one of the most complex as it’s close to central London with high levels of pedestrian and vehicular traffic.

Following several site visits and meetings, we rearranged the schedule to take account of feedback raised by the public and local stakeholders. This included:

  • Planning and splitting scoped works to make sure road diversions were kept as short as possible, minimising disruption to the local communities
  • Considering the local infrastructure, such as scheduling works near schools during school holidays, and those near shops at night-time or early morning, again taking into consideration the needs of the public
  • Liaising closely with local authorities and SCS JV to keep lane closures and bus stop and parking suspensions to a minimum
  • Planning closures and suspensions on a nightly or daily basis instead of large or lengthy closures which would affect residents and traffic flow
  • Produced a detailed risk assessment and method statement for each site, including traffic management to ensure the works could be carried out safely, with minimised risk and disruption
  • Provided a detailed programme of works, in accordance with the contract and NEC3 requirements, which was regularly updated and communicated to the project manager

Project Objectives/ Outcomes:

A detailed 3D topographical and subsurface model was required by the main contractor, Skanska Costain STRABAG JV (SCS JV), working on the HS2 state-of-the-art, high-speed rail line – the UK’s biggest infrastructure project.

Client:

Charles Brand

Date:

Jan 2020 – Sept 2020

Business Sectors: 

Water Resources/Civil Infrastructre

Services (Technical Disciplines):

Design

Our Role:

ByrneLooby’s multidisciplinary team of geotechnical and engineering experts undertook the following role: intricate design of the landside infrastructure at the terminal including pavement and drainage design, foundation design for lighting and CCTV towers. We also provided the following consultancy services: Geotechnical Advisor on settlement analysis, and design and value engineering support during construction phases. Construction started on this exciting project in October 2019.

A large proportion of the site was formed by reclamation and ground conditions which comprised of significant deposits of dredged infill, with near surface soils of low stiffness and high compressibility. To improve the near surface soils to facilitate improvement to lighting tower foundations and pavement design, ByrneLooby specified and verified ground improvement by High Energy Impact Compaction (HEIC) prior to pavement construction.

Given the high imposed pavement loads relative to the propose use, a relatively thick CBGM layer (470mm thickness) was required as determined by pavement design. This entailed placement of CBGM in dual lifts, and as such ByrneLooby defined and monitored a rigorous testing and verification strategy, inclusive of extensive trials, to ensure monolithic performance of the CBGM layer. This allowed the use of CBGM pavement solution, providing significant savings in both cost and program over an alternative Concrete Slab solution.

Project Objectives/ Outcomes:

ByrneLooby were appointed as lead designer for civil engineering company Charles Brand on a £9.5m contract to build the London Gateway commissioned by DP World, one of the world’s leading logistics firms. The London gateway development is located on the north side of the Thames Estuary and is a state-of-the-art deep-sea port & Logistics Park with rail terminal. A new empty container yard for the port will provide six hectares of empty container stacking area. The project comprises 80,000 m3 of bulk excavation and a heavy-duty pavement, comprising cement bound macadam with surface finishes of grouted macadam and block paving.
