The RIBA Professional Services Contract sub-advisor is appropriate in the event that an architect or advisor wishes to appoint a sub-advisor to the client who performs part of the architectural or consulting services, and if the contractual terms are consistent with the main agreement between the client and the architect or advisor. The new 2020 edition of the RIBA Subconsultant Professional Services Contract has been fully updated to align with the revised riba worktop and has the same back-to-back conditions and constraints as the standard RIBA Professional Services Contracts. Therefore, if an architect or advisor wishes or may be asked to appoint a sub-advisor to provide part of the architect/advisor`s services, the Head Agreement is a standard RIBA Professional Services contract. If the main agreement is not a standard contract for RIBA`s professional services, the agreement of the architect/adviser for the sub-advisor is a capped responsibility. If the architect/advisor has not been able to negotiate this capped liability in the head agreement, this can be serious. The RIBA Standard PSC has the most comprehensive service plan, which defines four roles – architect, senior designer, project manager and contract manager – and re-equips their services at every stage of the riba work plan. Other services can be listed at any stage of the work and/or selected separately in the calendar of other services. The RIBA Concise and Domestic PSCs include architecture services only with the ability to include additional rolls. The RIBA Domestic PSC is intended to be used with consumer customers and contains the required retraction form.
It also includes main design services (as is accepted by default if the client does not make separate appointments). The designer`s main tasks are excluded from the RIBA standard and the Concise PSCs, as the RIBA recommends appointing this role under a separate and autonomous PSC, hence the release of the new RIBA Principal Designer PSC. The RIBA PSC Sub-Advisor is where architects need sub-advisors or can be mandated by other companies and ensures compatibility with the RIBA Standard PSC. The RIBA-Subconsultant Professional Services Contract can be used when an architect/advisor is to be assigned to another architect/adviser and can be used for both commercial and non-commercial work, but only if the client is a commercial client.
