Requisite(s): 16105 Cost Management 1: Measurement

Description

This subject examines estimating practices and techniques typically used by contractors. Construction pricing underpins the subject and includes breaking construction costs and quantities into labour, material, plant, sub-contract and indirect cost components. The differences in quantity-related, time-related and fixed costs are explored. A series of tutorials and exercises in quantifying and pricing construction work items and activities are carried out by students. The subject then looks at more strategic estimating areas such as tender preparation, the use of builder's bills of quantities, obtaining and checking sub-contractor quotations, pricing preliminaries and determining margins for profit and overheads. Estimating software applications are utilised throughout the subject and students are exposed to leading edge practices that involve integrating construction cost estimating into building information modelling (BIM) systems.

Subject learning objectives (SLOs)

On successful completion of this subject, students should be able to:

1. Demonstrate a knowledge of the PMBOK Competency Unit for Project Cost Management
2. Understand the process of estimating and the techniques used by construction contractors in preparing a tender
3. Determine costs of construction for bill of quantities items by calculating unit rates based on labour, materials, plant and sub-contract components
4. Understand the use of published and historical cost data
5. Obtain and analyse the accuracy of sub-contract quotes and estimate the cost of facilities and supervision supplied by the head contractor
6. Understand the methods for calculation of profit and overheads
7. Assemble an estimate for tendering
8. Prepare unit rates using current estimating software available in Australia

Course intended learning outcomes (CILOs)

This subject also contributes to the following Course Intended Learning Outcomes:

  • Identify ethical issues and apply informed ethical judgements in professional Contexts. (A.1)
  • Work effectively in project teams in professional contexts. (C.2)
  • Operate effectively within the social, legal and technical framework of the design and construction process. (P.1)
  • Apply the body of knowledge underpinning construction project management practice. (P.2)
  • Develop strategic advice for clients on the costs and benefits of various courses of action involving construction projects and financing options. (P.5)
  • Demonstrate an understanding of construction technology and structural principles. (P.10)
  • Source evaluate and use information to approach new projects/problems. (R.1)

Contribution to the development of graduate attributes

The term CAPRI is used for the five Design, Architecture and Building faculty graduate attribute categories where:

C = communication and groupwork

A = attitudes and values

P = practical and professional

R = research and critique

I = innovation and creativity.

Course intended learning outcomes (CILOs) are linked to these categories using codes (e.g. C-1, A-3, P-4, etc.).

Teaching and learning strategies

The subject is delivered in blended learning approach with pre-recorded lectures (with online materials), and on-campus tutorials. The learning activities in this subject also involve a variety of assignments, quizzes and in-class tutorial tasks. A tutorial approach is used to give immediate feedback to students and to provide professional comment and advices.

Students are further supported through the use of UTS Canvas offering subject material and information moderation with the subject coordinator/lecturer. Pre-reading queries will be discussed and addressed before being applied in class exercises.

The option to attend classes online will no longer be continued for this subject. Regular class attendance (i.e. tutorial classes in this subject) is a requirement of the University. It is your responsibility as a student to attend lectures and tutorials, and to carry out all in-class assessment tasks.

Content (topics)

The content of this subject covers the following topics:

  • PMBOK Competency Units/Knowledge Areas in Project Cost Management
  • The development of techniques and skills for the pricing of construction works
  • Calculation of labour, material, plant, sub-contract and indirect costs
  • Determination of labour productivity rates
  • Preparation of trade estimates using built-up rates. Procedures for general building work, likely inclusions and omissions, allowances for waste, cutting and laps. Labour and plant production constants
  • Analysis of sub-contractors’ quotations, inclusion or exclusion of plants, tools, equipment, sheds, scaffolding, possible duplications and conditions of quotation
  • Identification and pricing of project preliminaries
  • Determination of profit and overhead, and rate distribution
  • Tender preparation and submission
  • Use of estimating software, e.g. iTwoCostX and/or Cubit
