c) Imagine you are a property developer assessing the construction costs for boundary walls.
Given that it cost N$235,000 to construct the brick boundary wall measuring a length of 97.8
running metres and a height (h) of 2 metres for an adjacent property.
Calculate the rate per square metre for constructing the brick boundary wall. Justify your
calculation, considering the total cost and total area (in square metres) covered by the
boundary wall.

construct the boundary wall for the subject property, assuming the height of the wall (h) is 2
metres. Clearly outline your steps and assumptions in the calculation.

Question 7
Construction Challenges & Decision Making
In the dynamic realm of construction, professionals frequently encounter various challenges and
scenarios that demand critical thinking, informed decision-making, and strategic problem-solving.
The following case studies and scenarios mirror real-world situations that you, as a construction
industry professional, may face in your career. They are designed to test your knowledge,
analytical skills, and ability to make decisions that prioritise both the project's success and the
welfare of all stakeholders involved.
Read each scenario carefully and provide thoughtful and well-reasoned solutions to the challenges
presented. Remember, in the construction industry, every decision can have lasting impacts, so
consider both immediate and long-term consequences in your responses.
ANSWERALL THEQUESTIONS.
a) A large construction project is underway. The Project Manager is on an unplanned leave,
and the Resident Engineer notices that the subcontractors are not following the specified
contract documents. The subcontractors argue that their way is faster and more cost-
effective.
i) Analyse the situation. What are the potential implications if the subcontractors
continue not following the contract documents?
(2)
ii) Evaluate the Resident Engineer's role in this scenario. What should the Resident
Engineer do to handle this situation?
(3)
iii) Propose a strategy that should be followed to avoid such a situation in the future. (2)
b) The Clerk of Works has identified that the materials supplied are substandard and could
compromise the structural integrity of the building. What immediate and long-term actions
should be taken to resolve this issue?

c) A subcontractor specialising in reinforced concrete is significantly lagging behind the
schedule, causing delays in subsequent tasks. How should the Project Manager handle this,
ensuring minimum impact on the project?
(3)
d) Unstable Ground: You are a site planner and have just been handed the results of a soil test
for a new residential project. The soil is loose and moist in some areas, potentially indicating
a risk for future subsidence.
i) How would you approach this challenge?
(3)
ii) Would you recommend construction adaptations, or would you advise selecting a
different site? Justify your decision.
