performed by the Works Package Contractor to ensure that all machinery, apparatus and systems, insofar as is possible, is capable of being fully operated by the Works Package Contractor to satisfy all Integrated Test functions and tests to be performed during the Test Running period.
“Completion Tests” means tests including Installation Tests, PAT, SAT, TOC and PRO to be executed after the supply, delivery and installation of the Permanent Works but prior to practical completion of the Works or after any part of the Permanent Works contained in any section of the Works is installed but prior to practical completion of the section of the Works in which the part is comprised.
“Contractor’s Independent Checking Engineer” means the Registered Professional Engineer appointed by the Works Package Contractor to independently check and certify the design of Temporary Works.
"Defined Area" means an area of track as described in Clause G2.11.
“Design Documents” means all drawings, design calculations, software, specifications, samples, patterns, models, written procedures and all other documents and things relating to the design of the Permanent Works and/or the Temporary Works which are prepared by or on behalf of the Works Package Contractor.
"General Works Train" or “Works Train” means any rolling stock provided by the PDP or the Works Package Contractor respectively for the purpose of carrying out installation and testing works within the Defined Area or Restricted Area. “Integrated Test” means those system‐wide operability tests
to be undertaken by the Works Package Contractor whereby the Works Package Contractor shall demonstrate the compatibility between his plant and the plant of Other Works Contractors.
“Monthly Progress Report” means a report which shall be prepared and submitted by the Works Package Contractor to the PDP on a monthly basis, detailing the progress of the Contract and other matters as specified in Section G12. "Operating Railway" means the existing railway tracks

“ ‘S’ curve” means the graphical relationship between the planned (and actual where appropriate) quantity of completed work (or resources) and time. The curve produced is to be illustrated on an accumulative basis where the slope of the line indicates the rate of undertaking the work or rate of expenditure of the resources.
“Test Running” means that period of PAT, SAT, and TOC prior to Trial Running when the Other Works Contractors shall be testing their plant and equipment and run the same in conjunction with the Railway Operator. In addition during this period system‐wide tests shall be undertaken that shall require the attendance of relevant Other Works Contractors. “Trial Running” means that period immediately following the
completion of a section of railway under construction, but prior to opening, when the Railway Operator shall be operating the rolling stock and all other systems and generally using the railway as though a scheduled service was operating, except for the absence of fare‐paying passengers.
