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. Like other models that involve the contractor in design discussions, the IPD model (AIA C191 – 2009) reduces the risk of disagreement between different contractors over design details during the construction phase; However, direct management of multiple contracts is also an increased risk and responsibility for the owner. 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. While the trustee has more contractual risks of taking direct responsibility for the subcontractors` performance in relation to the service construction management contract (CCDC 5A – 2010), the owner remains at risk for the cost and time uncertainties associated with this model, while the project is designed, auctioned and evaluated in phases. The general contractor who receives this contract outsources the various trades (for example. B using the agreed-upon subcontractor price (CCA 1 – 2008) that the general contractor will assume responsibility as the contractor during construction. The Construction Management Contract for Services (CCDC 5A – 2010) format is signed by the owner and site manager, in conjunction with the contract for contractors for construction management projects (CCDC 17 – 2010) and in connection with a separate contract, a parallel design consulting contract, under which the services provided by the owner`s advisor for the provision of project planning and contract management services (i.e. the contract standard engineering owner advice) or industry standard models such as ACEC 31 – 2010 for engineers or RAIC 6 – for architects in 2017). 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. Separate qualified advice for the owner is particularly important if the owner does not wish to rely on the builder`s design contractor as a payment certifier under the contract, and this role plays directly or through a separate contract.
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 construction management contract for services and construction (CCDC 5B – 2010) is used in circumstances similar to those of the Service Construction Management Contract (CCDC 5A – 2010), with the site manager making contributions to the owner and design consultant, while the project will be built in stages when the various design components are completed.
