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.

Services (Technical Disciplines):

Construction Supervision, Contractors Support, Monitoring, Project Management, technical assistance

Project Objectives/ Outcomes:

An alumina operator in Bahrain was expanding its smelter operations with a sizable CAPEX investment making the project one of the largest brownfield developments in the region. Due to this expansion, the operator needed to increase the import of raw materials via its existing port facility. The upgrade included the demolition of an existing warehouse, the construction of two large silos and the expansion of the existing jetties to accommodate and unload 60,000-ton Panamax alumina vessels.

ByrneLooby added value for the client by recommending an alternative solution as outlined in the preferred bid. This consisted of installing 2 VSUs on the upgraded Jetty 2 which allowed speedier loading times for the 60,000-ton Panamax vessels, hence optimising the required works. Furthermore, ByrneLooby reviewed all technical submission for the proposed marine works (including upgrade of Jetty 1 and 2) according to the relevant codes and in line with the client’s expectations.

Our Role:

ByrneLooby was appointed as the Engineers Representative (ER) to provide technical assistance and construction supervision services of all civil and marine-related elements for the Alumina Pier Extension.

The teams scope included various elements some of those being reviewing and approving designs for all marine construction drawings (pier extension and access trestle), along with the construction drawings for the onshore structures (silos and conveyor system) which form part of this contract.

Through initiatives led by ByrneLooby site personnel, the team was able to lead design value-engineering exercises to reduce construction times and eliminate interruptions to the berthing and offloading operations of the client’s vital material offloading at the port.  ByrneLooby also conducted daily site inspections during the construction phase to ensure compliance with approved drawings and approved design standards.

River Dargle Flood Defence Scheme | JB Barry & Partners

Location:

Wicklow, Ireland

Client: 

Bray Town Council

Business Sectors: 

Civil Infrastructure

Services (Technical Disciplines):

The Scheme comprised of a variety of flood defences including construction of new sections of earth embankments, demolition and rebuilding of river walls with extensive stone and timber/timber-type facing, channel excavation and regrading, and river bank strengthening. A range of landscape treatments in and adjacent to the river are proposed to mitigate the impacts of the scheme on the local environment along the river corridor.

Project Objectives/ Outcomes:

The purpose of the scheme was to protect the town of Bray, County Wicklow from flooding from the River Dargle. The Works consisted of the design and construction of flood defences, river widening and regrading along the lower reaches of the River Dargle.

The works extended over approximately 3.3 km of the river from the N11 Bridge to the DART Harbour Bridge. The flood defences were required to provide protection against a 1 in 100 year fluvial flood and 1 in 200 year tidal flood. The Works also included the design and construction of 7mx4m culvert adjacent to Bray Bridge, the only vehicular bridge in Bray Town, to act as a fourth arch to the bridge.

Environmental Assessment

Project Objectives/ Outcomes:

Previous site investigations including limited environmental sampling for soils had been undertaken prior to the commencement of construction activities. which suggests the material would be classified as Non-Hazardous. This testing frequency was not be considered to be adequate in accordance with the relevant codes of practice to allow classification of the materials at the site.

Due to the limited environmental sampling undertaken to date, FT deemed that further environmental assessment of soils at the site during construction was required to determine the suitability for reuse and categorisation of the waste status of material to be removed from site for disposal.

Our Role: 

FT supervised and managed intrusive investigations and soil/made ground sampling program to complete a comprehensive assessment of the contaminative status of soils/made ground at the development. This included analysis of laboratory testing, completion of generic risk assessment and recommendations for material reuse or disposal options for materials at the site.

Project Title: 

Clonakilty Flood Relief Scheme | Rubicon Heritage

Location:

Clonakilty, County Cork

Date:

2020

Client: 

Ward and Burke Construction

Business Sectors: 

Civil Infrastructure

Services (Technical Disciplines):

  1. Provide archaeological consultancy and advice to the Design Team during project planning.
  2. Provide all required archaeological supervision and services (Survey, monitoring and excavation) required during construction.

Project Objectives/ Outcomes:

  • Understand and characterise the archaeological environment of the proposed flood relief scheme.
  • Minimise the impact of the development on the archaeology through effective mitigation strategies
  • Preservation by record of any archaeology likely to be impacted by the scheme

Heritage assets and their significance were highlighted to the design team in order to allow them to make an informed decision on the preferred design in relation to heritage. As part of the process of preparing the Cultural Heritage Chapter of the EIA we produced a Mitigation Strategy which provided a strategy for facilitating development within a tailored programme of archaeological work in order to mitigate the impact of the development on known and potential archaeological remains.

Our field teams recorded all known archaeology in advance of construction and monitored construction works in order to identify any previously unidentified archaeological sites. We excavated four disturbed burnt mounds in Miles townland to the west of Clonakilty, within the impact of the Fluvial Storage Area, including a stone-lined trough.

We found remains of the earlier quay wall at Deasy’s Quay, but no trace of the shipyard visible on the historic maps. At Kent Street we found a cobbled surface outside the Fire Station which likely related to the old Fish Market – present on the site until the 19th century and we assisted with survey and recording during the process to number, deconstruct, store and rebuild a portion of the old market wall which is incorporated into the fire station structure.

Our Role: 

  • Cultural Heritage Constraints Study
  • Design Options Appraisal
  • Cultural Heritage Chapter for EIA
  • Historic Building Recording
  • Archaeological Monitoring
  • Archaeological Excavations
  • Post-excavation analysis and Reporting

Location:

Dublin City

Client: 

Sisk Steconfer JV

Business Sectors: 

Civil Infrastructure

Services (Technical Disciplines):

  • Survey
  • Engineering
  • Geospatial Data Collection

Project Objectives/ Outcomes:

This critical piece of urban infrastructure links up two existing light rail corridors in Dublin city centre comprising of 5.9km of new track, 13 new stops and associated works. Murphy Geospatial were the Geospatial Managers for the entire project working in partnership with the Sisk Steconfer JV. Geospatial certainty throughout the life cycle of the project, managed reliably by an experienced Murphy Geospatial team, was a key reason this project was delivered on time and on budget.

Our Role: 

Murphy Geospatial played a critical role in the success of the project, delivering surveying and engineering services during the design and construction phase. Our Head of Digital Construction, Michael Durnin, acted as Chief Surveyor with SS JV and oversaw every aspect of survey and geospatial data collection including establishing the control network, all setting out works, deformation monitoring and subsurface mapping.

Early engagement and collaboration during the pre-construction phase was the key to success. Murphy Geospatial strong and trusted relationship with the Sisk Group over years of working together was also instrumental.

Technical sensor driven solutions were used to automate the data capture process. Compared to more traditional methods this reduced risk, cost and optimised efficiency. Data management workflows were also integrated into the project which increased on-site efficiency and productivity.

Challenges during the project included TII’s construction specifications. 1mm relative change over 1m of track was an extremely tight tolerance for rail construction. 1:60,000 linear accuracy and 5√k for control are both very difficult to achieve in a heavily urbanised environment and in phased construction works.

The specification also included localised variables for paving under tight constraints where real-time decisions against design were made by the setting out teams.

Despite facing tight constraints and the challenges of such a large and complex site, the survey works were completed to a high standard in line with the specification.

Key Construction Statistics

  • Total single line track: 13.4km
  • Total weight of the tracks: 1,520 tonnes
  • On street, concrete track bed and shoulders poured: 13,600m3
  • Total ducting and pipes under the surface: 178,000m
  • Projected total man hours to complete SSJV works: 3 million hours

  • Topographical Surveys

Project Objectives/ Outcomes:

Eccles Heath Bridge (ETN 1613) is a three-span overbridge (7.5T) carrying a single lane road over the up and down lines of ETN Ely to Norwich (non-electrified route). Following an incident in December 2017, where a vehicle collided with the existing parapets, the bridge has been closed to road traffic. Installation of new compliant parapets was not feasible, thus, full superstructure replacement was required The initial works were to carry out a track alignment and road survey for the bridge. This was subsequently extended to include a topographical survey of an adjacent field to be used as a site compound. Finally, we were commissioned to locate and mark the location of buried services within the field in order to facilitate the planning of heavy lifting works.

Our Role: 

Murphy Geospatial have a long experience working in the rail environment and are fully conversant in Network Rail Standards and Procedures.  The brief for these works was governed by strict adherence to these requirements, together with the requirement to complete the survey within the restricted time access available.  A team of rail survey specialists in topographical surveys, laser scanning and sub-surface utility surveyors, together with our 3D modellers was designated to this project.

Process

Whilst the Network Rail standards are clearly defined, we worked closely with the client to determine the exact deliverables and the most practical and cost-efficient format.

Given the restrictions on access it was important to plan the right blend of experienced personnel with the latest equipment sufficient to complete the works with contingency available to allow for possible delays.

The works were executed according to plan; The following items were issued:

Detailed survey report to NR/L2/TRK/3100 standard to include witness diagrams, schedule of control, traverse and level diagrams and accuracy obtained.
Digital data a) Registered point cloud data in scanworld, combined and unified database outputs (*.IMP files), and *.POD files. b) 3D Wire frame model (Microstation .dgn) – topographical data extraction from point cloud including utilities tracing and plotting in 3D.

Initial expectations were met and the client subsequently commissioned further works on the project.
