**Question 1.** Which of the following best defines the “Four Rs” principle in construction
logistics?
A) Reduce, Reuse, Recycle, Recover
B) Right Material, Right Time, Right Place, Right Condition
C) Risk, Resources, Reliability, Reporting
D) Review, Refine, Re‑schedule, Release
**Answer:** B
**Explanation:** The “Four Rs” are a cornerstone of site logistics, ensuring that the correct
material arrives at the correct location, at the correct time, and in the correct condition to avoid
delays and waste.
**Question 2.** At which stage of the construction life cycle is the logistics manager most
involved in developing the site access plan?
A) Design development
B) Pre‑construction planning
C) Construction execution
D) Handover and demobilisation
**Answer:** B
**Explanation:** During pre‑construction planning the logistics manager analyses site
constraints, stakeholder requirements and regulatory permits to design an access plan that will
be used throughout construction.
**Question 3.** Who holds ultimate responsibility for coordinating deliveries with
subcontractors on a large commercial project?
A) Site Supervisor
B) Logistics Manager
C) Project Manager

Operations CLOSOP Exam
D) Procurement Officer
**Answer:** B
**Explanation:** The logistics manager orchestrates delivery schedules, communicates with
subcontractors and ensures that material flow aligns with the construction programme.
**Question 4.** In supply chain integration, which diagram most accurately depicts the flow of
materials from raw‑material supplier to point of use on site?
A) Linear chain diagram
B) Hub‑and‑spoke network
C) Circular loop diagram
D) Matrix flow chart
**Answer:** B
**Explanation:** A hub‑and‑spoke model shows a central distribution hub (often the site store)
receiving supplies from multiple suppliers (spokes) and dispatching them to various
consumption points.
**Question 5.** Which KPI is most directly linked to site congestion?
A) Cost‑per‑delivery
B) Vehicle‑hours per week
C) Carbon footprint per tonne‑km
D) Number of safety incidents
**Answer:** B
**Explanation:** Vehicle‑hours per week measures the amount of time vehicles occupy site
roads, providing a clear indication of congestion levels.
**Question 6.** When designing a site layout, what is the primary reason for allocating
separate zones for hazardous material storage?
, AICM Certified Construction Logistics Site
Operations CLOSOP Exam
A) To reduce transportation distance
B) To comply with fire‑code segregation requirements
C) To maximise use of available space
D) To simplify inventory counting
**Answer:** B
**Explanation:** Hazardous materials must be isolated to meet fire‑code and health‑safety
regulations, preventing cross‑contamination and reducing risk.
**Question 7.** Which of the following is a key feature of an effective Traffic Management Plan
(TMP) on a construction site adjacent to a public highway?
A) Permanent one‑way road layout
B) Unlimited vehicle holding areas
C) Designated entry/exit points with signage and speed‑reduction measures
D) Open access for all contractors at any time
**Answer:** C
**Explanation:** TMPs aim to control vehicle flow, protect the public, and minimise disruption
by clearly marking entry/exit points and imposing speed limits.
**Question 8.** What is the main advantage of a Just‑in‑Time (JIT) delivery strategy on a
high‑rise build?
A) Increased on‑site inventory for flexibility
B) Reduced need for on‑site storage space and lower material handling costs
C) Ability to delay deliveries without penalty
D) Simplified procurement contracts
**Answer:** B
**Explanation:** JIT deliveries align material arrival with installation schedules, minimising
on‑site storage, handling, and the risk of damage or theft.

**Question 9.** Which technology is most suitable for real‑time tracking of individual pallets
within a site store?
A) GPS satellite tracking
B.1) RFID tags with handheld readers
C) Manual paper logbooks
D) Barcode scanning at dock doors only
**Answer:** B
**Explanation:** RFID enables rapid, non‑line‑of‑sight identification of pallets, providing instant
location data without manual entry.
**Question 10.** In crane coordination, what does “crane‑time optimisation” primarily aim to
reduce?
A) Number of crane operators required
B) Idle time of the crane between lifts
C) Height of the crane mast
D) Load‑capacity of the crane
**Answer:** B
**Explanation:** Optimising crane time focuses on scheduling lifts to minimise periods where
the crane is on‑site but not actively lifting, thereby reducing costs.
**Question 11.** Which factor is least likely to affect the selection of a temporary power source
for site offices?
A) Proximity to the main grid
B) Noise emissions
C) Colour of the generator housing
D) Fuel availability on site
