Who is primarily responsible for preparing bidding documents?

The architect or engineer typically takes on the primary responsibility for preparing bidding documents. This is because they are usually in charge of the design and technical specifications of a project, which are essential components of the bidding documents. These professionals ensure that the drawings and specifications clearly outline the requirements and expectations for the project, allowing contractors to submit accurate bids.

Additionally, the architect or engineer coordinates the overall project requirements and adheres to relevant codes and standards, making their role crucial in the preparation of these documents. This includes not only the construction drawings and specifications but also the general conditions and supplementary conditions that govern the bidding and contract processes.

In contrast, the owner is focused on financing and overall project goals, while the general contractor, and subcontractor are typically engaged later in the process to respond to the bidding documents prepared by the architect or engineer. Their roles are vital for project execution but do not primarily involve the initial creation of bidding documents.
