Question 1

The critical path in a project schedule refers to:

Accepted Answer

The critical path is the longest sequence of dependent activities from project start to finish. Any delay to a critical path activity directly delays the project completion date. Float (slack) on the critical path is zero.

Question 2

Float (slack) in a project schedule refers to:

Accepted Answer

Float (or slack) is the amount of time a non-critical activity can be delayed without pushing back the project completion. Activities on the critical path have zero float.

Question 3

A Gantt chart is primarily used to:

Accepted Answer

A Gantt chart displays project activities as horizontal bars against a time axis, showing scheduled start dates, durations, and finish dates. It provides a visual overview of the project schedule and activity sequence.

Question 4

A Request for Information (RFI) is typically submitted by the contractor to:

Accepted Answer

An RFI (Request for Information) is a formal written question submitted by the contractor to the designer or owner when the contract documents are unclear, incomplete, or conflicting. The RFI process creates a documented record of clarifications.

Question 5

The three constraints of project management commonly referred to as the 'triple constraint' are:

Accepted Answer

The project management triple constraint — scope, schedule, and cost — are interdependent. Changing one typically affects the others. Quality is sometimes added as a fourth constraint in the expanded model.

Question 6

Submittal review (shop drawings, product data) by the architect/engineer serves to:

Accepted Answer

Submittal review verifies that proposed materials, equipment, and fabrication details conform to the design intent in the contract documents. It does not transfer design responsibility or liability to the contractor.

Question 7

A daily field report (or superintendent's log) should document:

Accepted Answer

A daily field report creates a contemporaneous record of site conditions. It should document weather, number of workers by trade, equipment present, work performed, deliveries, visitors, and any incidents. It serves as critical evidence in disputes.

Question 8

Project close-out documents typically include all of the following EXCEPT:

Accepted Answer

Close-out documents include as-built drawings, O&M manuals, warranty certificates, training records, lien waivers, and attic stock. Original bid documents and quantity takeoffs are internal contractor documents, not owner close-out deliverables.

Question 9

The purpose of a pre-construction meeting is to:

Accepted Answer

A pre-construction meeting brings together the owner, designer, contractor, and key subcontractors to review contract requirements, safety plans, communication protocols, schedule milestones, and site logistics before any work begins.

Question 10

Project acceleration (crashing) involves:

Accepted Answer

Project acceleration (crashing) reduces project duration by adding resources such as labor, overtime, or equipment to critical path activities. It typically increases project cost and may affect quality or safety if not managed carefully.
