ABSTRACT
One of the key features of the new FIDIC Form of Contracts for Underground Works (the “Emerald Book”) is the remeasurement of time and of quantities for excavation, support and lining of the works. It is an important aspect of the balanced allocation of risk related to the subsurface conditions, as in this way, the effectively encountered ground is taken into account. In the tender documents, the relevant quantities are presented in specific schedules for time related, quantity related and value related cost items. These items are the used by the Contractor and the Engineer in order to establish the realized works on a regular basis, allowing for a timely issuing of the necessary statements, as well as for the control of cost evolution in the project. The present contribution is one of several regarding the Emerald Book, and treats the remeasurement process and tools regarding time and quantity related cost items, as well as the documents that must be prepared by the Employer prior to issuing the tender documents during his procurement process.
