Architectural construction administration and site reviews
OAN Architect provides construction administration to support the architectural design as work moves from drawings to the site. We address design questions, carry out site reviews and coordinate architectural information with the owner, contractor and consultants within the agreed scope. Based in Welland, we support projects across Ontario, with the level of involvement and site attendance defined for each project.

- Property owners moving an architectural project into construction
- Homeowners building a custom home, addition or major renovation
- Business owners and developers coordinating a building or renovation
- Owners who need architectural support for construction-stage questions
When to get started
- The contractor needs clarification of the architectural drawings
- An existing condition or proposed change affects the design
- You need architectural site reviews at an agreed level of involvement
- The owner, contractor and consultants need coordinated design information
01In detail
Architectural support during construction
Questions can arise when drawings meet existing conditions, material choices and work on site. Construction administration provides a defined point of contact for architectural decisions and coordination.

Drawing clarification and design questions
We help explain the architectural intent and respond to questions about the design documents. Where a question involves another discipline, we coordinate input from the consultant responsible. The aim is to give the project team the architectural information it needs to address the issue.
Proposed changes and existing conditions
A discovered condition or proposed change may affect the layout, details or other design disciplines. We discuss the architectural implications with you and the project team, then prepare the agreed clarification or revisions. Any additional design or application work is identified as the issue becomes clear.
02In detail
Site reviews and project communication
The level of construction-stage involvement should be established before work begins. We agree the architectural review scope and how observations and questions will be communicated.

Architectural site reviews
Site reviews provide an opportunity to observe work in relation to the architectural documents and identify matters for follow-up within our scope. Visits occur at the level agreed for the project. They are not a promise of continuous attendance or a review of every part of the work.
Coordination with the construction team
We communicate architectural observations and design responses with the owner, contractor and relevant consultants. Clear responsibilities help the team know who needs to address a question and what information is outstanding. Engineering matters remain with the licensed consultants responsible for those designs.

05Common questions
Questions about construction administration
Does OAN stay involved after the drawings are complete?
Yes. We offer construction administration, including architectural questions, site reviews and coordination within an agreed scope. Discuss the support you need before construction begins so the responsibilities and level of involvement are clear.
How often will the architect visit the site?
Site attendance is established for each project in the appointment. It depends on the work and the scope of architectural review. Contact us to discuss the proposed construction and the level of support required; there is no universal visit schedule.
What happens when the contractor has a design question?
We address architectural questions within our scope and coordinate input from other consultants where needed. If a question requires a design change or additional services, we discuss the next step with the owner and project team.
Does construction administration include continuous site supervision?
Continuous supervision is not assumed in our construction administration scope. The contractor carries out construction, while OAN provides the agreed architectural support and site reviews. Your appointment sets out the specific services and attendance arrangements.
