The Landscape architect may assist the client in finding contractors to bid on and build their project.
If the client is not in the public sector and knows of a contractor they feel comfortable with, bidding is not necessary. They should feel free to get a price from that contractor.
Bids from two to three reputable contractors is recommended. The construction documents are submitted to contractors for pricing. Unless the client is an entity with restrictions, they may choose whomever they wish regardless of who is lowest bidder. The bidders should not bid unless they have personally seen the project area and reviewed the plans on the actual site.

A contract is signed by the Client with the contractor of their choice.
Note: In addition to the time it takes to complete the previous processes, finding available contractors and getting complete and accurate pricing can take weeks or even months before a contract is signed or work begins. It is best to plan projects as far in advance as is possible.
