Learning Outcomes to be Assessed:
- Review contractors tenders received, record and analyse, presenting a final
recommendation. - Interpret civil engineering information to compile a pricing document for tender
purposes. - Describe and quantify civil engineering works in accordance with HKCESMM.
- Construct descriptions of work appropriate to the work sections being measured, cost
and represent in a priced Bill of Quantities.
Assessment Details:
Part 1 – Civils Costing (Approximately 18 hours preparation/equivalent to 2,000 words)
(total: 30%)
Preambles and Preliminaries are commonly stipulated in the bills of quantities of civil
works. With reference to the HKCESMM, relevant government circulars and the Hong
Kong government conditions of contract for civil works, you write an investigation report
in around 2,000 words for the following:- Define the meaning of preambles and discuss the difference in unit rate of bored pile
shafts when the unit of bored piles shaft is changed from metre (m) to number (nr). - Define the meaning of Preliminaries and discuss the difference in costs of transport
for the engineer when the item coverage of transport for the Engineer is changed
from “the item shall include for vehicle licence fee, fuel, cleaning, repairing,
maintenance and accessories” to “the item shall include for fuel and reparing”. - Write Preamble clauses and Preliminaries items that are appeared in bills of
quantities. - Discuss how you handle errors found in the tenderer’s pricing documents attached in
Appendix A.
Part 2 –Civils Measurement (Approximately 36 hours preparation), this is an individual
assessment. (70 %)
Take off the quantities of bored piles, pile testing and concrete and formworks for the
retaining walls shown on the attached drawing Nos. 202003-1001, 1002 100, 100,
1005,1006 & 1007 (total 7 Nos), in accordance with the Government of HKSAR CESMM
1992 edition with corrigendum upto September 2011.
Prepare a bills of quantities based on the quantities taken off.
You can make any assumption while you discover any information missed from the given
drawings.
