Reflection

Time flies doesn’t it, the 9 weeks of consistent guest lecture presentation has come to an end, so as this semester and what does this indicates HOLIDAYS YAY!!!!!!!!!!!!!!!!!
But before that I still need to finish off this blog with the reflection on how innovation can be driven by IT in construction project management and study for the coming final exams -__________-!
Anyway, after listening to the 9 great presentations of the lecture series, it has helped me gain so much knowledge in various sector of the construction or property firms,. This was delivered through the presentation of GIS,BIM,RP data to property management ,Building Digital Project and 5 D modelling.

In the current building industry today, all design documentation are recorded in one accessible model by the design and management team who are involved on the particular project through BIM, and this has proven by various big companies like Hansen Yuncken’s that the IT innovation of Building Information Modelling has not only changed the construction industry from the traditional use of 2D CAD technology to 3D digital representation of building model, but allowing building works to change more easily and to predict the performance of the projects before they have built through simulation.

Moreover, the advanced Building Digital Project software used by ARUB on building the complex shape of the Dr Chau CHak Wing building to a co-ordinate X,Y,Z points. All the IT innovation of technology has driven the construction building to a new level to development, which speeds up the construction time, save on project cost and at the same time provides a quality effective finishing.

Week 10 Chris Linning – SOH


It is quiet fortunate to have Chris Linning as our last guest lecturer for the 9 weeks lecture series, the face of business has dramatically changed in the past 60 years as corporation have responded to increasing competition in a business environment that has expanded exponentially from local, to national, to global. These pressures have forced the construction industry to be more flexible and responsive to rapidly changing market condition,political and technology impacts regulatory requirements.

The Sydney Opera House Project was also competitive as 6 companies took in operation of the project delivery to ensure the accuracy of the project and to stay on schedule for the completion data, this project is another example of use of 3D modeling by using of BIM technology just like how i talked about on week 6 & 7’s blog.

Firstly, I would like to show my appreciation to Caitlin Hintz a Quantity Survey at Mitchell Brandtman who flew over from Melbourne just to present to us on this week’s lecture series.
The traditional way of Quantity Survey is a way of extract quantities putting number against to it and produces the estimates, but at Mitchell Brandtman a professional Quantity Survey firm provides detailed and accurate 5D estimates and living cost plans at any phase from concept design through to the construction and completion.

The 5D Quantity Surveying process is refined by Mitchell Brandtman into 4 distinct stages. LOD 100 – LOD500 (LOD = Level of development or Level of detail). For example, start of LOD 100 with basic geometry with not much data inputs, LOD200 a little bit more detail like basic (solid/light weight) wall, roof with not detailed description of the material parts, moving towards to LOD300 a precise geometry stating the specific construction materials, finishes and services specifications (e.g. stud wall with plasterboard on both sides and insulation in the middle). LOD400/500 is fabrication model and taking to the construction. All this can be delivered by Costx reader version of the bill of quantities with the BIM model of the project building to the client to create a easy visualisation.

Michael starts of a brief outline of the company he worked for Hansen Yuncken, Hansen Yuncken is one of the top 500 private owned companies in Australia, it has being continual operation for over 90 years. Today, Hansen Yuncken has an annual turnover exceeding $1.2billion, employing more than 650 people nationally. Further, he also mentioned about a flash back in 2009 of the Julia Gillard Stimulus Plan for school, during that time Hansen Yuncken has to manage 203 projects in a very tight time frame, so the transaction from spreadsheet to data base is needed and the power of visual imaging. Everything they did for the project was relying on GIS, this allowing the flexibility of the management to talk the issues to the client without travelling down to every project site in a tight working frame.

Hansen Yuncken’s entire portfolio of construction projects can be viewed in a geographical representation via Google Earth, with the ability to view each project to analyse live data delivered from enterprise application.

It is a great privilege to have Julian D’onofrio Project Engineer ( worked 8 years with lend lease ) and Rick Benjamin Structural BIM Technician ( worked 5 Years with ARUP Sydney ) to talk about on the Dr Chau Chak Wing building.

Traditional building practice relies upon drawings 2 dimensions. Building designs are communicated through dozens of separate documents. However, CAD documents usually exclude the very information necessary for effective design evaluation and construction(e.g. Timelines, price lists specifications).

On the other hand, BIM is more than drawings, it is data for building design, construction and maintenance information combined in to one model, but for complex shape buildings like Dr Chau Chak Wing Building needed to use the software ‘Building Digital Project’ to create 3D modelling. This software was designed by Gehry Technologies it allows building model to co-ordinate X,Y,Z points ( Z- Co-ordinates are RLs).The building is virtually built on a 3D model (e.g. facade elements -substructure and curtain walls) before built on site and prefabricate put it together like a puzzle on site. Both guest lecturers also updated the current construction of the building, commenting on it as being great and the accuracy of it being purely because of the 3D modelling.

The use and development of BIM technology has rapidly changed the construction industry from the traditional use of 2D CAD technology to 3D digital representation of a building model. This allows building works to change more easily and to predict the performance of projects before they are built through simulation.

For instance, a door of certain material and dimension needs to be changed, this change can be made through 3D model instantly. This has made a better communication of information for everyone who are involved in the project (e.g. builders and sub-contractors) through 3D visualisation. It also creates better co-ordinations for building professionals for accuracy as the model consists of a particular design, material and cost used on the project, which saves on construction time and cost.

RP data was used for property valuation reference by the real estate agency for many years, the Property Information can be searched by state, suburb, street and unit number through RP data. Property reports can also be seen such as the ownership and sales history of the properties. It also provides Suburb Statistics report of a particular suburb, an estimate of the current value of the property can be produced by RP data (valuation report) this is based on the past sales near the area within the past 12 months. There are also Market and Rental Comparison reports and more.
RP 1 RP Data

As mentioned by Allan the RP Data is a rich reference source for historical contents and suburb information, but many photo graphs of the properties does not match with the property description as this is taken by individuals, unlike Western Australian taken by the Land tittles office so errors can be made in NSW. Some of the properties even do not provide or has a wrong area size. I agree with the fact that sometimes there is a need to be physically on the site that you research on or work on in order to double check or find out the current condition of the property.

IT requirements are pushing us to explore more effective IT system that would allow us to see and understand more about building efficiency.
The lecturer states that building can be measured building by a range of tools, NABERs is a tool that is developed and managed nationally by the NSW office of Environment and Heritage, this tool allows us to measure the performance of the building’s energy, water, waste, and indoor environment (air quality).
IMG_3954 IMG_3958

Furthermore, the Green star rating tool is voluntary tool that is developed by the Green building Council of Australian, it evaluates the environmental design and construction of the buildings (e.g. bike racks on site) used by the Architects for their innovation for design for its client, whereas NABERs is more on how to maintain a building.

About three year ago mandatory disclosure for commercial office space of 2000 square metres or more are required to have a rating certificate of the building’s efficiency to show the energy consumption for 12 month with 75% occupancy of the building, without this rating certificate the commercial office building can’t be sold, bought or leased.
Wandering why this is so important?
Week 4 Week 4 - 1

It’s all about the environmental awareness use of non renewable resources and sustainability issues that drive the technology to develop a high performance energy efficiency building, which would interests the landlords, tenants and the environment. Moreover, she also mentioned two and half stars was an average rating building and six star was outstanding sustainable building, an example given was 161 Castlereagh street, Sydney. It was originally designed as a 5 Star Green Star building but the Green Building Council of Australia has awarded the development a 6 Star Green Star. Some of the features that have pushed 161 Castlereagh Street from 5 Star to 6 Star Green Star Include:
 Tri- generation plants, generating electricity, heating and cooling for the air conditioning and hot water systems through the use of gas clean energy.
 A high performance thermal shielded glass exterior, allowing in maximum light and reflects heats off the glass without creating a reflection that will disturb neighbouring buildings.
 External sun senses to help the building adjust during the day and afternoon.
 Efficient lift system with floor to destination control
 Designed to bring 150% of the outside air into the building
 Motion senses on the floor for lighting.

Since 1991 Estate Master has been developing a suite of powerful , flexible and easy to use property development software including:
 Development Feasibility- can perform risk assessment on the project, while compare multiple options (e.g. calculate key investment performance) to ensure the best financial outcome achieved for development site.

 Development Management- It import expenditure and revenue data from accounting system which will help you track your development cash flow from project commences right through to completion.

 Corporate Consolidation – It is a central management tool for archiving, managing, tracking which generate detailed reports of the entire property development.

 Investment Appraisal -It calculates property purchase and sales values for property valuation and investment analysis.

 Hotel Feasibility – It determine the acquisition price and impacts due change of price in a hotel base on average occupancy rates.

Even after the first few weeks of university it was still struggle to get up for a morning lecture at 9 am sharp. Maybe I was too relaxed during my mid semester break, but there was no other choice, as there would be consecutive guess lecture talks every week until week 9 (15th October).
