1) Estimating is important at different stages of construction procurement to provide budget comparisons, assess tenders, predict project timelines, and allocate budgets. 2) Measurement involves calculating material quantities, tendering involves contractors bidding with profits, and estimating involves calculating total project costs without profits. 3) Preliminaries items provide important project details and include site administration, waste management, insurances, reports, and temporary facilities like electricity. Examples given are site security, waste plans, risk insurance, soil reports, and small plant allowance.

7. Question 1 (b)
Differences Measurement Tendering Estimating
Measurement is a process of
calculating the quantity for
different materials to produce
an accurate quantities and
descriptions by apply a rule or
set of rules.
Tendering is a process of bidding
and obtaining the construction
project by contractors.
Estimating is the process of
calculating the net cost required
to carry out the construction
work.
Involve in different
construction
procurement process
Involved in both pre-contract
and post-contract work.
Involved in pre-contract work
only.
Involved in both pre-contract and
post-contract work.
Purpose It provides the quantity of
materials required for the
construction project.
It provides the price of estimated
cost and profit for contractors to
tender the project.
It provides the estimating cost of
preliminaries, plant, labour and
material cost, daywork, provisional
sums, prime cost sums and
contingencies.
Profit Without profit. With profit. Without profit.
Application Application on SMM. Application on Bill of Quantity. Application on the building up
rate.

Measurement + Rates
Estimating + Profit
