• Tunnelling and Shafts
• Geotechnical Engineering
• Preparation of Full Tender
Documents
• Technical Specifications and Bills of
Quantities
• Preparation of Capital Cost
Estimates
• Project Management
• Seismic Retrofiting and Repairing
Roads & Bridges
We are committed to design services in highway / railway transportation projects. Design services include route selection and analysis, comprehensive topographical, hydrological and geological investigations and studies. We develop bridge solutions for road, rail and pedestrian traffic. For structural analysis of bridges and viaducts completed to date we have typically employed:
• Advanced finite element modelling (Time History, pushover)
• Construction staged effects
• Second-order buckling analysis
The majority of our designs for clients are undertaken to British Standards and AASHTO to suit the requirements of the approving authorities in the local market.
The services delivered by our bridge design specialists include:
• Concept design of footbridges
• Full design of pre-tensioned, post-
tensioned, reinforced, steel and composite sections road and rail bridges
• Assessmentofexistingreinforced and pre-stressed concrete road bridges
Tunnels
BIR delivers design services to clients in tunnelling design:
• Geological, hydrogeological and geotechnical analysis, stress analysis and design of the final lining
• Monitoring of soil behaviour during and after construction
• Techniques of prestabilisation and support
• Assessment of excavation methods
Our role includes the full multidisciplinary design and management of the civil works including:
• Geotechnical and site surveys
• Bored tunnels (using earth pressure
balancing TBMs)
Transport & Structures have long been one of our core business..
• Cut and cover tunnels
• Viaducts and bridges (utilising
post- tensioned, segmental bridge
construction)
• Route alignment
• Elevated, at-grade and underground
stations (utilising top down constructed station boxes with diaphragm walls)
Railways
BIR follows the national and international specifications to find the most economic and functional solutions in the transportation projects. In the design stages,
all possible alternative routes
and superstructure systems are investigated and assessed for comparison with the relevant cost- benefit analyses.
Our rail design services include:
• Civil design for railways
• Building design for stations
• Station boxes and diaphragm walls
• Architecture,structureandbuilding
services
• Ventilation and fire engineering
• Underground, at grade and elevated
stations
• Depots
Airports
BIR offers overall planning of
airports combines the architecturally demanding and economically rigorous design of passenger terminals with the planning of airside areas and facilities as well as landside traffic development.
We offer overall planning solutions for air traffic facilities embracing the following services:
• Master planning
• Passenger terminals
• Operation-specific buildings
• Technical building equipment
• Aircraft manoeuvring areas
• Engineering structures
• Landside traffic development
• Project management
