LARE Project and Construction Management Questions and Answers — Questions and Answers
Question 1: 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?
- Issue a Construction Change Directive (CCD) to authorize the substitution immediately to avoid delays.
- Verbally approve the substitution with the contractor and document it in the next field report.
- Request a formal Change Order proposal from the contractor detailing cost and schedule impacts. (Correct answer)
- Reject the substitution outright as it deviates from the contract documents.
Correct 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.
Question 2: 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?
- Cost-Plus Contract
- Time and Materials (T&M) Contract
- Unit Price Contract
- Lump Sum (Fixed Price) Contract (Correct answer)
Correct 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.
Question 3: In project scheduling, which of the following best distinguishes the Program Evaluation and Review Technique (PERT) from the Critical Path Method (CPM)?
- PERT is used exclusively for construction projects, while CPM is used for research and development.
- PERT uses a probabilistic time estimate to account for uncertainty in activity durations, while CPM uses a single, deterministic time estimate. (Correct answer)
- CPM focuses on identifying project milestones, whereas PERT focuses on resource allocation and cost control.
- PERT is a visual technique represented by an activity-on-node diagram, while CPM uses an activity-on-arrow diagram.
Correct 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.
Question 4: 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:
- Contractual Completion
- Substantial Completion
- Final Completion (Correct answer)
- Mechanical Completion
Correct 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.
Question 5: 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?
- Upholding the project schedule
- Conflict of Interest (Correct answer)
- Ensuring quality of materials
- Maintaining the project budget
Correct 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.
Question 6: 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?
- General Conditions
- Addenda
- Specifications (Correct answer)
- Shop Drawings
Correct 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.
