Construction Management Questions

In organizational theory for project execution, a purely military organization structure is classically referred to as a line organisation (single, direct chain of command).

A Critical Path Network (CPM/PERT) helps the engineer focus on critical activities, reallocate resources from noncritical leads to critical ones, and avoid project-wide delays—i.e., all of the above.

Select the correct logical sequence for concrete works: (1) Erection of formwork → (2) Pouring of concrete → (3) Curing of concrete → (4) Removal of formwork.

The CPM family of terms commonly includes CPA (Critical Path Analysis), CPP (Critical Path Plotted), MCE (Minimum Cost Expenditure during time–cost trade-off), and CPS (Critical Path Scheduling): effectively, all of the above.

About activity float in networks: float can be positive, zero, or negative; positive float allows delay up to its value without delaying the project; negative float implies inevitable project delay unless recovered; zero float marks a critical activity—i.e., all the above.

In CPM terminology, the performance of a specific, measurable task consuming time and/or resources is called an activity (events are milestones; dummies carry logic only).

In an Activity-on-Arrow network, a dummy activity is an artificial, dotted-line connector that consumes no time—used solely to preserve logic and uniqueness of event numbering.

For any activity with duration D, the standard CPM timing relations are: EF = ES + D, LS = LF - D, LF = LS + D, and D = EF - ES—hence, all the listed relations hold good.

Critical Path Method (CPM) improves on bar charts, offers a realistic problem-solving framework, reduces delays common with simple bars, and was introduced in 1957 by Morgan R. Walker (DuPont) and James E. Kelley (Remington Rand)—therefore, all the above.

CPM (Critical Path Method) characteristics: which statements correctly describe CPM network analysis in construction project planning?

PERT (Program Evaluation and Review Technique) uses three-time estimates for each activity. Which set correctly represents the PERT basis?

Bar chart planning granularity: For a concrete job covering (1) supply of materials, (2) formwork, (3) reinforcement and placing of concrete, (4) removal of formwork, and (5) curing of concrete, how many separate bars should ideally be shown on a bar chart?

While pricing and submitting a tender (bid) for construction work, which of the following does a prudent contractor assess before quoting?

Network theory basics: identify the correct statements about slack, critical path, and project duration in CPM/PERT networks.

Line organisation (classical scalar structure): what is its principal advantage in construction firms and public works departments?

Network time computations: Which statements about forward pass, backward pass, and event time selection rules are correct in CPM/PERT?

Construction management – Line organization: What is the principal disadvantage of a pure line organisation structure in a construction firm or project department?

Bar (Gantt) charts in project control: Which of the following is an incorrect statement about Bar Charts used for planning and monitoring construction activities?

Critical Path Method (CPM): In a project network, the critical path represents which of the following for overall project completion?

Pre-tender stage in project delivery: Which activities are normally completed before inviting tenders for a construction project?
