These lists of master`s contracts should be established for a pre-defined period or with update procedures to include new contractors in the roll-up table and be accompanied by pre-qualification rules setting a maximum value for a given task, so that all employment contracts exceeding the maximum value can be awarded as part of a public tendering process. The “contract for the agreed price” format (CCDC 2 – 2008) is used by the owner in combination with a separate consulting contract (i.e. the standard owner`s consulting contract for engineers, either standard industry models such as ACEC 31 – 2010 for engineers or raic 6 – 2017 for architects), under which the services provided by planning advisors and owner sub-advisors for the provision of project planning services contract management services remain at the owner`s expense during the construction phase. For the compliance of commercial contracts, the use of this format is most appropriate in combination with a pre-qualification procedure, in particular a supplier qualification contract (RFSQ) – a framework agreement that defines the process of awarding work for a list of several contractors who can deal with a downstream employment contract under the master`s agreement. Prices for these types of contracts can then be set on a price basis in downstream bidding procedures. Compared to the traditional contract (CCDC 2 – 2008), which requires the owner to manage the two contractors separately, the consolidation of the role of advisor and contractor in a project construction contract reduces the risk of disputes and disagreements between the planning consultant and the contractor during construction; However, this approach also removes a level of control and balance between these two roles, as the design consultant is no longer independent and directly with the owner. Master Agreement Between Owner and Contractor (CCDC 2MA – 2016) The Master Agreement Between Owner and Contractor (CCDC 2MA – 2016) was developed to be used by owners in ongoing construction or maintenance programs. This format allows the parties to enter into specific work agreements on the basis of the terms and conditions of sale, so that the parties can avoid renegotiating these terms and conditions for each employment contract. As with the predetermined sum model (contract contract (CCDC 2 – 2008), the owner should maintain parallel design consulting services to develop specifications for different work orders.
