The RIBA Sub-Consultant PSC is for Denk, where architects need sub-consultants or can be mandated by other companies, and ensures compatibility with the RIBA Standard PSC. As you can see, although the suite claims to distribute the risk in a fair and balanced way, the changes mentioned above tend to favor the architect and reinforce the perception that RIBA agreements are favorable to consultants. As a result, this may deter developers or business customers from opting for the 2010 RIBA agreements in favor of a tailor-made date, an alternative standard form, or a heavily modified RIBA contract. Consultants are usually professionals appointed by the client to perform expert tasks for a project. This is similar to the relationship between contractors, contractors and subcontractors. The senior advisor may want to ensure that they have back-to-back clauses in their own consulting contract and in the sub-consulting contract, so as not to be exposed. This is not always easy to negotiate and the best way to achieve this is to design and agree on consulting and sub-consulting contracts simultaneously. The sub-advisory contract should cover issues such as the transfer of copyright to the lead advisor and the timing of payments, so that the senior advisor`s cash flows from its own payments are appropriate and it can meet the requirements of the Housing Grant, Construction and Regeneration Act, which would allow a sub-advisor to suspend the benefit for non-payment.
