Accepted Answer

32 inches

Answer

ANSI Z60.1 specifies a minimum 32-inch root ball diameter for a 3-inch caliper balled-and-burlapped deciduous shade tree.

Question 2

During a pre-bid site visit, a prospective contractor notices that existing tree roots extend into the proposed paving area but are not shown on the drawings. The contractor does not raise the issue and submits a standard bid. Who bears the cost risk if root removal causes delays?

Accepted Answer

The contractor, because they had opportunity to observe and price the condition

Answer

When bidders have the opportunity to observe existing site conditions during a pre-bid walkthrough and do not raise them, they generally assume the risk of those visible conditions.

Question 3

What is the purpose of a 'Notice to Proceed' in a construction contract?

Accepted Answer

It authorizes the contractor to begin mobilizing and construction work

Answer

A Notice to Proceed is the formal owner directive that establishes the contract start date and authorizes the contractor to begin work.

Question 4

A landscape contractor wants to substitute a nursery stock species not listed in the specifications. Under standard AIA contract conditions, who must approve the substitution?

Accepted Answer

The landscape architect

Answer

Substitutions require the landscape architect's written approval, as the design professional is responsible for ensuring the substitution meets design intent and specification requirements.

Question 5

A retaining wall installation is proceeding faster than planned, and the contractor proposes skipping the required 3-day cure time between concrete lifts to stay ahead of schedule. What should the landscape architect do?

Accepted Answer

Require adherence to the specified cure time to ensure structural integrity

Answer

Specified cure times are structural requirements; allowing shortcuts that compromise structural integrity exposes the owner to liability and the LA to professional negligence.
