Project Brief

You have been hired asthe BIM manager for a prefab construction factory that aims to deliver prefabricated components of granny flats. The first  project you come across  is to  build  a granny flat in the backyard of a house located in Sydney, NSW (anywhere in Sydney, you choose the  location) .  You  are  required  to  undertake  the  necessary  steps  to  produce  the required design documentation, includingthe 3D model, time scheduling and simulation (4D BIM), BIM based cost estimates (5D BIM), and the BIM based sustainability reports of the granny flat (7DBIM) to be constructed.

You can choose one of the footprints demonstrated in the links below:

https://grannyflatsaustralia.com.au/floor-plans/matilda/

https://grannyflatsaustralia.com.au/floor-plans/lily/

https://grannyflatsaustralia.com.au/floor-plans/melaleuca/

You are to come up with the dimensions of the project so you can make some changes of the dimensions for the footprint you choose. For your granny flat’s roof type, consider a popular roof type you can see from Google Earth Pro for the location you choose.

An integral part of your work is to produce a BIM model.  The client states that you have the liberty to choose appropriate materials, color, and embedded information for your model elements. Note that you are to choose any land allotment in Sydney as the hypothetical site for this assignment (does not need to be empty land) .

Report Details

The full report you are to produce will act a learning journal for you with a maximum of

2700 words, consisting of the following sections:

Report Section 1 (max. 200 words)

This section should include a map of the location of the land and discussion on the following:

•    Project scope and site logistics Report Section 2 (max. 300 words)

In this section, you are to detail the 3D model of the granny flat. In particular, you should consider the following when producing your 3D model:

•   3D model of the topography linked to your architectural models (everything should be linked together)

•   Appropriate 2D annotated section drawings showing details of the building, with appropriate title blocks

•   Appropriate plan views, with room details.

•   Appropriate 3D views

Since dimensions have not been specified in the plans, you have the liberty to adopt appropriate measures that are realistic. In terms of material types and textures for model elements, you are entitled to use any appropriate material which you deem fit, so long as the choice makes sense.

Report Section 3 (max. 200 words)

In this report section, you are required to document your steps that explain to a client the predicted scheduling of the project, through producing a 4D construction simulation of   your 3D BIM above using Navisworks. In particular, you should pay attention to the following:

•    Integrate the 3D model with a project schedule by defining appropriate selection sets

•   The simulation clip created (mp4 file format) should be 15s long (take snap shot)

•   A timeline isto be imported to Navisworks using MS Project or Excel Report Section 4 (max. 500 words)

In this section, you are required to document your learning journey to describe how a  reasonable cost of your project can be generated, based on the 3Darchitectural model created in Section 2. This is to be achieved using CostX or Revit, using your 3D model.

In particular, you should pay attention to the following:

•    Ensure you set up an appropriate rates library in CostX. You can use a common cost database such as Rawlinsons. It is expected that you have multiple rate components when setting up your rates library (i.e. labour cost + material cost etc) .

•   There are many options for creating dimension groups in CostX. The easiest is through a template

•   Your estimate needs to be based on a 3D model. 2D cost estimation will not be accepted (take snap shots and insert in your report)

Generate professional cost estimation reports form. CostX and report the results in your report submission.

Report Section 5 (max. 700 words)

An integral part of a project is the sustainability analysis conducted to ensure high performance of the design. Make sure to add a few scenarios so that you achieve a green scenario for energy performance of the design. Justify which changes in your initial BIM model results in better outcome for energy saving in your best scenario. Include a diagram/graph of your scenarios’ energy performance. Two analyses (among three sustainability analyses you have learnt in this course) are sufficient for this    section.  Please note your discussion in this part needs to be more specific to choosing only a few factors that have a significant impact on building costs and are also reasonable.

Report Section 6 (max. 800 words)

In this part, you demonstrate your ability to analyze how your model should be modified with changes in the location, climate, budget, scope of project etc. Choose three questions from the list below to  answer and include at the end of your report.

Section 6 questions - answer only three questions among the questions below (foryour answers, correctness of the answers is important not the number of words):

Q1.If you are asked to save $14,000 on the cost of your granny flat, can you still maintain the sustainability of the granny flat based on your BIM-based sustainability analysis in Insight? Add screenshots from your Project report or BIM model to support your answer to this question.

Q2.Imagine you are working in a BIM design company and your designed BIM model has

gained interest for application to other cities worldwide. Your BIM manager asks you to replicate the BIM model for use in suburbs of London and Toronto. You only have one week to do so. You need to prepare 3D, 4D, 5D and sustainability analyses for the granny flat in these countries within that week. What are the major changes you need to make for your granny flat’s 3D, 4D, 5D and 7D BIM to prepare a design appropriate for these two cities? Explain how the location of the granny flat impacts its price. Support your answer by adding screenshots of your Project assignment report.

Q3.What are the main changes for the sustainability analysis (lighting, solar gain and energy optimization) of your building when you:

•    increase or decrease the size of the windows;

•    change the shape of the roof;

•    rotate the building; and

•    add plants on any side of the building.

Please explain each of the scenarios above by adding manual sketches or screenshots from your granny flat’s BIM model.

Q4.Discuss the affordability vs sustainability of your granny flat’s BIM model if you

•    use sustainable materials for the granny flat; and

•    introduce different roof shapes for increasing solar gain.

You don't need to make these changes in your BIM model for this question. Only discuss and add screenshots of your current model from your granny flat.

Q5.Will you be able to construct a more sustainable building of your granny flat (e.g., by using more sustainable materials) by only spending extra $15,000 compared to the initial cost of your granny flat’s BIM model? For your answer to this question, use data and cost estimations from your own granny flat models.

Notes:

2). In order to be able to complete Report Section 3-6 you will be required to have a 3D model from Section 2 ready.

3) . Although Report Section 1 will have to appear first in your final submission report, it is advised that you write it at the end to ensure that you have a full grasp of the modelling required for the full project.

4) . Indicate the number of questions that are going to be answered in section 6. If the questions are copied and pasted in your submitted file, they won’t be counted for the number of words that need to be written for section 6.

5) . The report needs to be typed up. No scanning is allowed for the report content.

6) . You will need to have snap shots throughout the report to demonstrate that some/all of the assessment checklist items mentioned above have been attempted.

7) . In order to achieve objective 2 you need to:

•     research on the ways you can increase the sustainability of your own model by changing the materials or the design of the house, sth like climatic design of your own model.

•     research on sustainability vs affordability.

•     sustainable materials impact on the building price

FAQ: How to do 4D and 7D forthe this project assignment?

For 4D BIM of your major project, please prepare a construction plan via Project software and save it as mpp, then convert it to mpx using the link given in Moodle and also, accessible below:

https://products.aspose.app/tasks/conversion/mpp-to-mpx

make sure to consider schedule for all the spatial components of your 3D BIM model in this plan. The mpx file can then be used in Navisworks to be added to your 3D BIM Model.

In order to bring your 3D BIM model in Navisworks, you need to save it as nwc using nwc exporter plugin in Revit or export it as dwffile. Both nwc and dwf files can be read by Navisworks. Save the Navisworks file and export the animation file for submission.

For 7D BIM in Major project, please use the tutorial instructions to apply on your 3D BIM model and make three analyses i.e. energy optimisation, day lighting and solar access.

See the link below from minute 35 to see how to interpret the results of Insight for your energy optimisation and how you can decrease the energy cost for your Building model.

https://www.youtube.com/watch?v=7CrG6hw1Wdo&t=3010s

add screenshots of these analyses in your report.
