Question 1: What is the purpose or advantage of having a location plan in relation to your
proposed building development?
Answer:
Location plans indicate the positioning of a block within the estate or development area.
Question 2: It is important to read and understand the “Title Block”
a) What information does it contain?
b) Amendments are shown on Title Blocks. Why are these important?
Answer:
a) It gives vital information such as: The drawing number, Amendment numbers indicating
amendments to the plan, who drew the plans, what date the plans were drawn Lot
number, street address and what the scale of the drawing is.
b) They show/ indicate current amendment to the plan.
Question 3: It is important to read and understand the “Site Plan” effectively.
a) Name 3 key features of a site plan.
b) Describe why each one is important?
Answer:
a) Easements, Contour lines, and Boundary off-sets.
b)
i. Easements: these are sections of the land which are designated for services such
as Sewer, Storm water, Common Electrical and Fire breaks.
ii. Contour lines: these are generally constructed over the site plan. They are
important because they provide information on how much slop or fall is on the
land. Contour lines or Integers are separated by even increments of measurement
in height.
iii. Boundary off-sets: these are important because they give us a start point for
setting out our building. Encroaching on these will give you and the owner/s a lot
of problems with both the local authority (council) and financial problems.
Question 4:
Reference the plans Blue Dog Training have supplied in the project overview.

CPCCBC4012B 3
a) What easements are present on the plans?
b) How might they affect the building design on the land?
Answer:
a) Easements in the plan include; Drainage easement 0.5m from boundary, electricity
connection box, and drainage surface inlet pit.
b) Buildings cannot be constructed where they would obstruct such easements since the
easements are critical to house planning and building.
Question 5:
Reference the plans Blue Dog Training have supplied in the project overview.
a) Calculate the amount of fall between the North-Western corners of the house to the South -
Eastern corner of the house. (Highest to lowest)?
b) How did you determine this?
Answer:
a) 70-68.5=+1.5m (1.5 m increment)
b) By reading contour at northwestern corner of the house and subtracting from the contour
reading at south eastern corner of the house.
Question 6: When setting out the location of the house position on the land, boundary off-sets
are critical.
a) Explain why and what impact it would have for you as the Builder and the Owner if the house
is incorrectly positioned.
b) How could this be avoided?
Answer:
a) Boundary off-sets are important because they give the start point for setting out of a
building. Encroaching on these will give you and the owner/s a lot of problems with both
the local authority (council) and financial problems. Council can make you either pull
down the structure or enforce a Boundary Relaxation (re-aligning of the building and
boundary off-sets).
b) By having an understanding of the Boundary Off-sets.

a) Outer Most Projection
b) At the outer edge of the fascia in relation to the boundary off-set.
c) 25.288m
Question 8:
How do you determine the orientation of a house by interpreting the site plan?
Answer:
The site plan will have a North point located on it and this will be used to determine the
orientation of the house.
Question 9: Existing services are to be located prior to construction.
a) How would you locate these?
b) What would be the impact if they are damaged from construction works? (I.e. fibre optic
cable, sewer, gas, water, electrical etc.)
Answer:
a) To locate services, you should identify these through either Dial before you dig, or a
qualified services location expert.
b)
i. Damaging any services will delay your progress on the job and may cost you a lot
of money.
ii. Damaging services may affect neighboring properties and disrupt supply of
services to these homes.
Question 10: If there is a discrepancy on the plan with the dimensions;
a) Who should you seek clarification from in order to get the correct information?
b) In what format should the clarification be given?
c) Who should you notify when this occurs?
Answer:
a) Owner and/ or architect.
b)
i. Double check all calculations and measurements to confirm.
ii. Notify the owner/s immediately

CPCCBC4012B 5

Question 12: What is the purpose of the floor plan?
Answer:

Question 14:
a) Explain why it is important to show the positions of any wet area set downs on a slab and
foundation plan.
b) What must you consider for a set down to be accurate and compliant?
Answer:
