Coursework 3 – (Individual Project Report) . Weighting (40%).
Task:
Sandford access bridge is situated near Oxford. The bridge was originally designed for an 18 tonne load capacity. The bridge deck has deteriorated rapidly over the last few years and the load capacity on the bridge is now restricted to 3 tonnes.

Feasibility studies were carried out and it was recommended to implement the preferred option, ‘to remove and dispose of the existing bridge deck and replace with the new precast bridge deck to the current British standards’. The duration of the construction works is 12 weeks and the total project duration from the planning stage is 36 weeks.

The task of this course work is to write a project report about how you will plan and manage the construction phase for the preferred option and must include:
• How you selected the design parameters to design the concrete deck- explaining, site investigation methods to establish the pile length underwater, as the as built drawings are not available and how you find out the strength of the current concrete works.
• Environmental socio-economic sustainability, innovation and ethical standards, availability of resources and compatibility in the preferred option in addition to its contextual and aesthetic impact.
• Develop the activity schedule for the works from planning to completion of the construction works and show the programme in a Gantt chart with critical path analysis. Please assume realistic duration for all activities to do the critical path analysis.

The page limit is 40 A4 sized pages which is approximately 12,000 words including references and bibliography at the end.

Background information is given below.

Background to the project
The bridge was built in the 1970s and it spans over the Sandford Lock bypass channel on the River Thames. It is approximately 6km South of Oxford city centre (Figure 1). It provides vehicular access to Sandford Lock for operational use, but being part of the Thames Path National Trail, it is used mostly for recreational purposes. The bridge is 40m long with five spans and carries a 3m wide roadway. The bridge was originally designed to carry a load of 18 tonnes gross vehicle weight. In 2007, a routine condition inspection was carried out by the Environment Agency and identified that the carrying capacity of the bridge had been reduced to 3 tonnes gross weight and, restricted the bridge use to only cars and vans.

Figure1: Location plan
To carry out the construction work it was necessary to close the footpath and the cycle path for several weeks and this would cause significant disruption to the local residents. It was important that the community were consulted about these works and their needs accounted for when planning the scheme.
It is important to minimise the environmental impacts through recycling and reusing the existing bridge deck and minimum damage to the surrounding environment. Necessary to prepare an environmental action plans and waste management plans for the project. Re-using the existing sub-structure proved to be the most sustainable of solutions in terms of cost, material use and carbon footprint of the other technically viable solutions. However, it is necessary to do the appropriate site investigation work to make sure that the substructure is strong enough to undertake the 18 tonne loading capacity.
