LARE Project and Construction Management Flashcards

During the construction of a public park, the contractor discovers that the specified bluestone pavers are unavailable due to a quarry strike. The contractor proposes substituting a different type of stone that is readily available. What is the first formal step the landscape architect should take in this situation?

Answer: Request a formal Change Order proposal from the contractor detailing cost and schedule impacts.

A Change Order is the formal process for altering the construction contract. When a substitution is proposed, the landscape architect must first receive a formal proposal from the contractor that outlines any changes to the contract sum or schedule. This allows the owner to make an informed decision. A Construction Change Directive is used when agreement on terms isn't reached but the work must proceed. Verbal approval is not contractually binding, and outright rejection without evaluation is unprofessional.

A landscape architect is managing a project where the client has a strict, non-negotiable budget. The scope of work is well-defined and a complete set of construction documents has been prepared. Which type of construction contract would be most appropriate for this scenario?

Answer: Lump Sum (Fixed Price) Contract

A Lump Sum or Fixed Price contract is ideal for projects with a clearly defined scope and a strict budget. The contractor agrees to complete the project for a predetermined, fixed price, which provides cost certainty for the owner. Cost-Plus, T&M, and Unit Price contracts are better suited for projects where the scope is not as well-defined or is likely to change.

In project scheduling, which of the following best distinguishes the Program Evaluation and Review Technique (PERT) from the Critical Path Method (CPM)?

Answer: PERT uses a probabilistic time estimate to account for uncertainty in activity durations, while CPM uses a single, deterministic time estimate.

The fundamental difference between PERT and CPM lies in their approach to time estimation. PERT is used for projects with uncertain activity durations (like research and development) and uses a three-point estimate (optimistic, most likely, pessimistic) to create a probabilistic duration. CPM, more common in construction, is deterministic and uses a single, well-defined duration for each activity.

A landscape architect is reviewing a contractor's application for payment at the end of a project. The contractor has completed all physical construction, including all punch list items, and has submitted all required closeout documents, such as warranties and as-built drawings. This milestone is known as:

Answer: Final Completion

Final Completion is the stage when all work is 100% finished, including the correction of all punch list items, and all contractual obligations (like submitting closeout documents) have been met. This is the trigger for the release of the final payment, including retainage. Substantial Completion is the earlier stage where the project is complete enough for the owner to occupy and use for its intended purpose, even though minor punch list items may remain.

During a weekly site observation meeting for a corporate campus project, a project manager for the client asks the landscape architect to award the irrigation subcontract to a specific company owned by the project manager's cousin, despite it not being the lowest bidder. Which of the following is the MOST significant ethical issue at play?

Answer: Conflict of Interest

This scenario presents a clear conflict of interest. The project manager's personal relationship is influencing a professional decision, which could compromise the project's integrity and fairness to other bidders. While budget, schedule, and quality are important, the primary ethical violation is the pressure to make a decision based on personal gain or relationships rather than the project's best interests.

Which of the following documents, typically prepared by the landscape architect, provides detailed, written requirements for materials, equipment, construction systems, standards, and workmanship for the work and is a critical component of the contract documents?

Answer: Specifications

Specifications are the written documents that complement the drawings. They describe the qualitative requirements for products, materials, and workmanship upon which the contract is based. General Conditions set forth the rights, responsibilities, and relationships of the parties. Addenda are modifications issued before the contract is signed. Shop drawings are prepared by the contractor or supplier to illustrate how specific components will be fabricated and installed.
