Complex projects contract

In November 2015, the Complex Projects Contract was updated and renamed the Time and cost management contract TCM15.


The Complex Projects Contract was developed by the Chartered Institute of Building (CIOB). It was called the 'Contract for use with Complex Projects, First Edition 2013'. However, it was also be referred to as the 'Complex Projects Contract 2013' or 'CPC 2013'.

Launched on 23 April 2013, it was thought to be the world's first contract specifically aimed at the management of time in complex construction and engineering projects. It was also the first standard form contract to cater for Building Information Modelling (BIM).

It was suited for works of high value or complexity, major real estate projects and engineering / infrastructure projects. It was less suited to simpler works or those of short duration, construction management / Engineering Procurement and Construction Management (EPCM) projects without amendment and inexperienced clients /contractors.

CPC 2013 was designed for use by companies and public authorities where works comprise complex building and / or engineering, which could not be expected to be managed intuitively. It could be used where the contractor was expected to construct works designed by or under the direction of the client with traditional drawings, specification and / or bills of quantities, or building information modelling, or on projects which required the contractor to design of part or all of the works.

The contract required a collaborative approach to the management of design, quality, time and cost. A working schedule, planning method statement and progress records were at the core of the management process. They were the tools by which all time and time-related cost issues were to be determined, and conformed with the standards required by the conditions, appendices and the CIOB's Guide to Good Practice in the Management of Time in Complex Projects.

It was strongly recommended that those intended to have a continuing responsibility during the course of the project in design, or in quality, time and / or cost control, or in administration, had at least achieved the standard of knowledge required by the CIOB's Certificate in Project Time Management, or its equivalent.
