Final answer:
B101 is an agreement defining the relationship between an owner and architect, which includes terms for the start and end dates of architectural construction phase services. These dates are set by a schedule in the agreement and usually span from the contract start of the construction to the issuance of the final certificate for payment.
Step-by-step explanation:
The document B101 refers to an agreement between an owner and an architect, which is provided by the American Institute of Architects (AIA). Regarding the start and end dates for construction phase services from the architect, B101 stipulates that these dates are established through a schedule that is defined within the agreement. The construction phase services commence when the owner's contractor is bound by a contract to start construction and typically conclude when the architect issues the final certificate for payment, signifying the completion of construction in accordance with the contract documents. However, B101 also provides for additional services after this point, if agreed upon by the owner and architect. It is essential for both parties to review the specific terms and conditions outlined in their customized B101 agreement to understand the precise start and end dates, as they can be subject to negotiation and revision based on the project's needs. Ultimately, any agreed upon construction start date and substantial completion date will be recorded within the contractual documentation.
