Due to the time-critical nature of the project and the handover and re-commissioning of the building ready for use by the university, the Board of Governors of the university have asked for a detailed section of this report to cover the means by which the contract deals with time and changes and how we can be reassured that the work can be completed by the due date? They have prepared the following scenario for you to use as a basis for your advice: During excavations for the basement and foundations of the new Burnaby building, the contractor has discovered a substantial number of brick and concrete structures which appear to be part of the building which was on the site prior to the construction of the Burnaby building in the 1980's. Explain how the contract and other documentation provides for this type of circumstance and provide a detailed assessment of how you, together with other members of the project team, would manage such a situation if this occurred and how this would be managed if this issue became a dispute
