The document discusses several infrastructure projects in the UK involving bridge and retaining wall design. It provides details on the structural elements designed, software used, design codes followed, and roles and responsibilities on each project. The projects included bridge assessments, refurbishments, and new designs incorporating concrete, steel, timber and prestressed structures. Design activities involved load calculations, 3D modeling, temporary works planning and site supervision.

1. M74 Motorway Completion - Scotland
• The M74 Completion scheme was a Design and Built Scheme and so design drawings
were issued in packages to suit a compressed programme where the design and
construction phases overlap
• Cat 3 Independent Design Check
• Used design codes: BS5400-4, BD37/01, BD21/01, TD19/06, BS6779 – 3 and 8500 -1
• Understood the principles of designing of RC concrete and prestressed concrete
structures
• Used design software: SuperSTRESS and SAM 2000
• liaised with geotechnical team and Introduced to geotechnical design principles

2. Glasgow Rd Underbridge
A three-span, 86m long, semi-integral bridge.
The bridge deck made of prestressed precast
U12 beams and an in-situ RC slab.
I designed the following elements:
•Pile caps
•Piers and abutments
•RC deck slab
•Prestressed beams
•Bearings for the abutments.

3. Farmeloan Rd Underbridge
A 58m long, three-span, integral bridge.
The deck is of prestressed precast concrete Y7
beams and an in-situ RC slab.
I designed the following elements:
•Created and analysed a 3D grillage model
using Super STRESS
•Piles and pile Caps
•Abutments and piers
•Prestressed beams
•RC Deck Slab and RC Parapet
•Diaphragm and Wing Walls.

4. Cambuslang Rd Underbridge
A 94.9m long, four-span, semi-integral bridge.
The superstructure consists of prestressed Y6
beams and a cast in-situ RC deck.
I designed the following elements:
•Piles and Pile Caps
•Abutments and Piers
•Prestressed beams
•RC Deck Slab and RC Parapet.

6. Salford Meadows International Footbridge Design Competition
I took part in the international RIBA competition for the design of a new pedestrian bridge
across the River Irwell led by Salford City Council.
My team of 4 engineers developed a conceptual design of underslung cable truss bridge.
Out of 203 submissions our design reached Stage 2, the short listed four submissions.
The submission can still be viewed on RIBA Competition web site

8. Design activities:
•Attended 3 day Lusas training course
•Undertaken an Initial dynamic analysis of behaviour of the structure to the moving and
pulsating pedestrian load
•I understood the basics of dynamic analysis.
•The bridge designed to carry 5kN/m2 crowd loading.
•The acceleration comfort criteria of the UK National Annex to Eurocode 1991-2
The following Engineering analysis work undertaken at competition stage.
I have created a 3D model of the bridge and completed preliminary static structural analysis
at Stages 1 of the competition, considering all the relevant load effects.
At Stage 2, I have additionally completed a preliminary dynamic analysis of the main span.
Several modes of the bridge had frequencies requiring further detailed consideration. For
these, I have undertaken a detailed time-history analysis, which showed that the bridge deck
accelerations satisfy the pedestrian comfort criteria.

9. Lancashire Bridge Assessment
• I have undertaken non intrusive Inspection For Assessment (dims, condition
survey and covemeter scan for reinforcement location)
• I produced Site Inspections method statements
• Produced a 3D space frame model using SuperSTRESS
• Carried out full structural assessment of the RC portal frame bridge.
• Section capacity checked using hand calculation methods as well as “SKALE”
design software.

10. • Example of 44t vehicle located on Portal 55 to gain Max Hogging moment.

11. • Bridge Assessment proved that the structure
can stand on its own but it is not able to
support any live loading including pedestrians.
•I have produced Assessment Report
recommending demolition of the bridge.
•Shortly after the Report, Stockport Council
decided to close the bridge for the traffic and
soon after that the bridge has been
demolished.

12. Marsh House Bridge
I have undertaken an initial hand calculation design of an abutment of a single leaf lifting
bridge carrying Marsh House Lane over the disused St Helen’s Canal. The deck was
hinged on the south side with hydraulic machinery in the designed box.
The box substructures consisted of reinforced concrete abutment founded on piles with
reinforced concrete canal walls approaching the abutments on both sides.

15. Red Brook Footbridge Refurbishment

16. • Assessed the bridge in accordance with
BS 5268 Part 2
• Produced Assessment Report
• Understood the principles of
permissible stress design of timber
structures,
• Understood different timber Strength
and service classes
• Produced Design, Specification and Bill
of Quantities for the bridge
refurbishment
• The following loadings have been used
during the design: 1.4kN/m load applied
to the top 1800mm high parapet to TD
19/06; 5kN/m2 footway loading to BD
37/01 and 8.12kN point load to The
British Horse Society Advice Note.

18. Dumvilles Brow Retaining Wall Strengthening

20. A hand sketch produced for the draughtsman

22. • Detailed design of strengthening of 3 No. masonry retaining walls supporting
highways.
• Wall A (8.0m high) – designed as reinforced concrete retaining wall. Due to
overturning and sliding instability the new wall was tied back to the existing
masonry wall and down to the rock foundation
• Wall B (5.5m high) – designed as brick wall fixed at the top to the RC stair case
and bottom to the bed rock. Also dowelled back in to the existing brick wall and to
the new adjacent RC L-shape wall.
• Wall C (4.0m high) – designed an underpinning for the foundation of wall that
showed signs of settlement. The underpinning in form of a series of pile caps
cantilevering under the wall. Wall B anchored to the staircase slab with series of
dowels.
• RC structures were designed using hand methods, however crack width and early
thermal cracking were checked using Excel spreadsheets.
