Project Brief Information Summary Beam road that located in the northern suburb of Brisbane city is predominately classified as an arterial road that connecting urban area and suburban area in the regional network. Therefore, beam road has an important function in east-west arterial routes as it also provide access to suburbs along its axis. Although Beam road categorizes as an arterial road, beam road does not provide a primary freight route access. However, since it connects the Sandgate road and Stanworth road where it linking to the access of gateway motorway. Now beam road allow a limited freight vehicle (19m semi-trailer,not oversize) to access the road. Nevertheless Beam road also can be categorized as an environment-friendly road for the cycling and also have 2 lanes dual carriageway. The only problem is that there are three train tracks which is the North Coast Railway Line (NCRL) with 40m width that cutting the Beam not perpendicularly also still in the form of open level crossing (OLC). With the facts that all the community services located near the Carseldine train station shows that lots of people crossing the OLC every. Nonetheless if we it look from a safety point of view, open level crossing is not suitable for current traffic flow. Also based on Queensland Level Safety Strategy Annual Report, in 2012 – 2021 the strategy aims to: o Eliminate Level Crossing Collision o Reduce the number of near miss incidents at level crossings o Minimize the impact of any incidents that occur

Since the current OLC giving high workload zone which inherently risky. Therefore, in this project we are assign to replace the Beam road OLC with Grade Separated Overpass of the NCRL

Project Task o Design the structural design of a four lane, dual carriageway bridge overpass of the North Coast Railway line and preserved northern busway corridor(including barriers and gantry signage structure), with a left side shoulder bicycle lane of 2.0m width on each carriageway, along with a separate 2.0m pedestrian path on each of the north and south sides of the overpass o Design the structural design of a pedestrian ramp from the pedestrian on the northern side of the overpass, to land indicatively adjacent to the present bus interchange at the Carseldine railway station

C.

Project Feasibility Study Here are the mind maps of how this project feasibility study will be done, We divide it into 6 consecutive steps.

2

C.1.

Traffic analysis

In this part of the study we will gather the information of : o The road characteristic like the vehicle volume etc that will be used to determine the work load of the overpass. o Nearby public transportation: since we know that there’s a Carseldine train station which also have bus interchange. That indicate public transport mode share would be high. Therefore, we need to know that, does this project will be affecting the public transport timetable. o City council plan for Beam road : we need to check whether this project is oppose the Kedron city council plan.

C.2.

Project location analysis

in this part we need to take account for all of the property nearby and do the risk management like whether we need to do the property acquisition or not, here are the list of nearby property: o

South-west quadrant: public open space and sporting field

o

South-east quadrant: car-wrecker yard

o

North-east quadrant: 25m unformed preserved corridor for the proposed future extension of the Northern Busway (north-south) with residential estate immediately to its east

o

North-west quadrant: Carseldine railway station park & ride lot, passenger set-down facility and bus interchange facility

Moreover, we need to analysis the suitable height and width of the overpass since we need to design it based on the corresponding train tracks width and the height of the electricity pole plus the suitable degree of incline for the disability people.

C.3.

Geotechnical Engineering Analysis o Preliminary maps analysis : to determine the road chainage for the overpass construction. o Contour maps analysis : is done to check whether the project location is located above some geological anomalies or not. o Soil analysis : is done to determine the soil property like the soil strength and layer, that will be used for designing the suitable foundation. o Overview the underground service maps : to make sure that the project will not accidently destroy the underground services

C.4.

Overpass structure design

As you can see from the mind map it tells you step by step what we need to do in this part of the study like we can determine the maximum load by the information that we gather in traffic analysis etc. but the main thing from this part that we should came up with one preliminary design that have higher allowable design load than the maximum working load.

C.5.

Pedestrian ramp design

After we finish with the dual carriage overpass we could just adjust the pedestrian ramps design so that I can suit perfectly with overpass design aesthetic and also the needs of the pedestrian. Besides those two reason, the overall calculation for this is only take little amount of time compare to the overpass and also customizable Each steps are done consecutively so that if one of the pervious steps doesn’t pass the feasibility study the rest of the steps would not be done. For example if this project conflict with the city council plan why we need to bother by building an overpass and also if the project location is located above type of soil that only could support limited amount of load and you need load of earth work then why you need to continue with the design study if its already cost so much until this stage.

The Main Components of the Structural Study Area D.1

Quantitative Analysis o Overpass Measurements In this part we going to analyze the appropriate length and width of the overpass so that we not design it to close to the electrical pole or to high o Load Analysis In this part we going to analyze the maximum load which is the working load that we could determine from the vehicle volume and traffic flow and also the design load which the load that can be supported by our structural design o Soil properties In this part we analyze the soil properties that affecting the calculation of foundation design such as bearing capacity, coefficient, and water table o Forces In this part we analyze and calculate all the forces that working in the structure such as bending moment, shear forces, and axial forces (compression and tension) o Money resource or budget Last but not least we need to balancing between our design and the budget itself

D.2.

Qualitative Analysis o Structural efficiency (to make sure that we not overly design our structure) o Materials grade and quality (to make sure that we not over spec the structure material) o Geological location (to make sure there no problem with the soil layer below the structure) o Where to put temporary crossing (to make sure we provide alternative route)

5

o Weather impacts (to make sure the design is suitable with the usual weather) o Service installation along the overpass (ex/ storm water management, cable installation, etc)

Project Package Design

White Hat – Information (what are the information need)

Red Hat – Feeling (what are my feelings about this)

Looking forward to came up with an suitable and efficient structural design Worrying about unexpected risk that I have to dealt with in the design process

Black Hat – Weaknesses (what is might wrong with this)

There are several private property around the project location, this project will affecting nearby public transport, and route diversion

Yellow Hat – Strengths (what are the good Points?)

This project could reducing road users workload, improve the traffic flow in beams road, and reducing risk on OLC

Green Hat – New Ideas (what are the possibilities)

Use precast material to speed up construction, use the suitable material but not expensive for pedestrian ramp such as timber deck. Use the simplest structure to speed up the design

8

Blue Hat – Thinking (what thinking is needed)

Careful thinking , logic thinking, and down to earth thinking

Based on all of the design thinking process above here are the proposed project package design for this project.

E.1 Foundation Design

Where we begin to choosing or designing the appropriate structure we always start by designing the suitable foundation type first. When we start designing a foundation there are a certain check-list we should do

Table. E.1.1 Foundation selection (Shaw, 2008)

After we know what types of foundation that appropriate for this project we could start designing it by calculation all the forces. And then we could choose how the construction of the foundation will be done. But from my point of view everything that precast is much more efficient in time and man power. For the materials it’s depending on the type of foundation it self

E.2.

Overpass structure design

In this part of design first thing to do is we determine what will be the working load of the overpass. And then we choose which type of structure that suitable for the overpass. In our opinion we would go with the precast segmental doubleT concrete that will be design in a little bit of an arch shape. The reason why we propose precast concrete structure is the fact that precast concrete is generally more durable than cast-in-place/in-situ concrete because of the controlled environment when the manufacturer producing the precast concrete. Besides , the precast also reducing the rate of cracking in the deck slab that making it less penetrable (smith, 2012).

The other reason why this structure is much better than the conventional one is that based in Li (Li, 2010) is that o Double-T design are valid for a range of span length used in highway overpass (which almost the same like Railway overpass) o Double-T design can reduce the system’s sensitivity to posttensioning losses o Compare to the conventional one the system is competitive by comparing material use, cost, scheduling and aesthetic criteria. But the main reason why choose precast and shaped a little bit like arch is that we can reduce the length of the overpass while maintaining the required height so that the overpass did not hit the electrical pole of the rail ways. Moreover, this shape also can help reducing the materials, time, money and all other resources that will be used.

13

E.3

Pedestrian Ramp design

In this part of the design we would to propose a pedestrian ramp design that still follow the guideline that affecting level of service. There are three main factors which are physical characteristic factors, location factors, and user factors. And in our design we try to keep maintaining some of the important point of factors from each factors such as for physical characteristic the main point is support facilities, location factors main point is connectivity, and for the user factor main points are personal security and mix path user (Gallin, 2001). These are the main guideline for us to designing the pedestrian ramp.

For the detailed design of pedestrian ramp itself we want to propose of using steel structure and timber deck. The reason of why we choosing this design is that to minimize the material cost and also reducing time of the construction since steel structure is way much more simple to build than a concrete structure for a small scale structure.
