200468 Estimating 1 Answers Assessment Answers

Task:

Part 1: From the table given above, you are required to select ONE group and explain how the factors in the chosen group generally affect accuracy of building cost estimating. You are required to bring examples from industry cases; and, research findings from relevant journal articles and books to support your discussion. Refer to FAQs given in vUWS.

• Include a title page, a small introduction and conclusion. 
• The body could be arranged in main and sub headings.
• The arguments should be supported with in-text references and analysed using appropriate tables and diagrams.  
• Add a list of references following HARVARD WESTERNSYDU referencing system after the conclusions (Please note that these references should match with the in-text citations).
• Also, add any appendices that show evidence of industry data collection e.g. interview notes, construction project details
• Please include the word count excluding references and appendices at the bottom of the title page.

Answer:

Introduction

If the actual cost exceeds the planned or estimated cost then the feasibility of the project will be interrupted. It is the role of the project head to consider some factors such as location and complexity of the project, price for the labours, price and quality of the materials, competitors, competitive market etc individually that may affect the construction cost estimation.

Part 1: Factor affecting accuracy of earlier stage building estimation for the chosen group

According to Shin (2015) the availability and type of specific material also affects the approach of construction cost estimation.  If the client of the project insists for any particular material or particular product on manufacture for the success of the project then the cost of the construction project can drive up over project cost. This is referred to as a type of close specification for the construction projects.

Part 2: Elemental VS Trade cost breakdown comparison

The building element related to the construction project that has been nominated is the internal wall. In order to design internal wall of the building the basic constriction materials which are required include bricks, plaster, cement, primer, paint etc (Correa 2016). According to a consistent analysis plan it has been found that Bills of Quantities (BQ) is referred to as one of the systematic ways which is applied in the construction industry whose primary objective is to create a fair agreement between the involved parties in construction.  

The trade items of a Bills of Quantities (BQ) are as follows:

• Preliminaries (actual construction contract)
• Facilitating works
• Substructure
• Superstructure
• Internal work finishing
• Fitting, furnishing and equipments
• Servicing
• External workings
• Risk analysis
• Provisional summation
• Credits
• Day-work
