Assignment 1
Assignment 1
0 There are three tasks to be done in this assignment.
Task 1 : Develop a brief project scenario from the project details given in Column 2 in Table 1
0 This means; you are required to describe further on the project design, materials used, services & facilities provided, functional area allocation, project duration, project cost etc..
E.g. Further development of scenario on design and materials (few elements) as follows:
Shape : Complex shaped tower with curved aluminum and glass exterior wall cladding.
Walls : Internal walls are finished with premium quality designer wall papers.
Floors : Common floor areas are finished with polished granite flooring and all internal floor areas of residential apartments are finished with premium quality designer carpets except for toilets.
0 Suggested word limit for this task is 250 words

0 There are three tasks to be done in this assignment.
Task 2 : Details of the preliminary estimating method adopted in preparing the early stage construction cost estimate
0 You are required to include ;
0 Preliminary estimating method used
E.g. Superficial floor area method (describe how this method was used for the chosen project to prepare the early stage cost estimate and why this method was selected)
0 What were the information available to prepare the preliminary estimate ?
E.g. sketch plans, functional area schedule etc.
0 At what stage of the project, the preliminary estimate was prepared ?
0 How did you find cost information (various sources)?
0 What were the assumptions made when preparing the preliminary estimate ?
0 Suggested word limit for this task is 250 words

0 There are three tasks to be done in this assignment.
Task 3 : Detailed analysis of the chosen factors that influenced on the accuracy of early stage construction cost estimate and caused the final construction cost of the project to vary significantly from it.
0 You are expected to select 2 to 3 factors from the predicted list of factors given in Column 3 in Table 1 for the chosen project scenario.
0 Suggested word limit for this task is 500 words.

Task 3 continued…
0 Select factors
E.g. of an influencing factor :
1. Plant, labour, material shortage and price escalations :
0 Analyze factors by providing supporting evidences E.g. for the above factor You could :
0 Compare martial, labor and plant market information (availability and price)at the time when the estimate was prepared and the actual construction happened
0 Provide information on drastic construction boom in Sydney / Sydney suburbs during 2016 – 2018
0 Include what % of cost (approximate) of the project was affected with this factor
0 Include some other facts to support your argument
(Your facts should support the argument “though you allowed adequately for price escalations in your estimate, drastic change in construction volume during the affected period impacted on the accuracy of your estimate)

0 There are three tasks to be done in this assignment.
Task 3 continued…
0 Select factors
E.g. of an influencing factor :
1. adverse weather conditions (droughts) made site operations difficult :
0 Analyze factors by providing supporting evidences E.g. for the above factor You could :
0 Compare the weather condition in Wagga Wagga (temperature, amount of rain) at the time when the estimate was prepared and the actual construction happened
0 Provide information on droughts condition in Wagga Wagga and regional NSW during 2016 – 2018
0 Include what site operations were affected by drought condition and how it affected
0 Include what % of cost (approximate) of the project was affected with this factor
0 Include some other facts to support your argument
(Your facts should support the argument “though you allowed adequately for adverse weather conditions in your estimate, unpredicted severe drought condition impacted on the accuracy of your estimate)
Assignment 1
0 Suggested information sources :
0 lecturers and tutorials
0 Published information : Text books, price books, research papers, newspapers, websites etc.
0 Information from the industry sources :
Example : Developers, Consultants, Contractors, Material suppliers etc.
0 Information from relevant authorities and institutions
Example : Banks, councils etc.
The evidence of data collection from above sources should be provided in Appendices
