Concepts
In order to demonstrate that Hepta Consulting is the right company for the Oaklands Park Grade
Separation Project, we have generated a list of ideas which we believe, best solve the problem at
hand. These concepts range in cost, scale, and time, all of which we consider to be extremely
important. A list of some of the initial concepts which are believed to address to previously supplied
Project Brief include:
Rail Overpass
Rail Underpass
Road Overpass
Road Underpass
50-50 grade separation
Modifications to the Diagonal Road/Morphett Road intersections immediately north and south of the
railway crossing
Boom gates
Removal of the Morphett Road/Diagonal Road intersection on the northern side of the railway line
Road widening
Installation/reprogramming of traffic signals surrounding the intersection
To consider which option is the most appropriate, Hepta Consulting will evaluate all ideas against a
set of general considerations. Some of these criteria can be seen listed below.
General
Project cost
Construction time
Disruption to services and residents
Available resources
Practicality
Visual amenity
Noise
Hepta Consulting is dedicated to finding the perfect solution to the Oaklands Park Railway Crossing
Area. To assist with this, engineering division specific question will be generated and answered for
each possible solution. A brief example of some of the questions that Hepta Consulting will ask can be
seen listed below.
Transport
Will projected the traffic flow be enough to be able to support the build and the cost?
During construction how will the traffic flow be affected?
If we leave the area as it is, how bad will the traffic get?
Structural
How big would a rail over pass (or any overpass) have to be?
Are there any implications with building large infrastructure in this area?
HEPTA CONSULTING 20
Geotechnical
Is the soil safe to build upon? Will the soil support extensive permanent vertical forces?
Is the area prone to any earthquake activity?
How deep will foundations need to be for any sort of overpass?
How far beneath the soil surface is bedrock located?
If an under pass is required is the soil safe to excavate?
Environmental
How will the local business cope during construction and after?
How will construction affect local housing/people’s lives?
Water/Utilities
Will the water-table effect any in ground construction?
Are these underground utilities in the immediate vicinity of the rail crossing? If so, where are they
located? How many homes will be affected? Where can they be shifted to?
What will happen with existing stormwater during construction?
Is the site prone to flooding?
These are just some of the things which will be considered by Hepta Consulting. In order to
appropriately determine the most feasible solution, further exploration into each idea is needed to
see which will achieve the best possible outcome respective of the Oaklands Park Grade Separation
project brief.
HEPTA CONSULTING 21
Scope of Works
Transport Division
Major components
Due to the 30-year plan for Greater Adelaide, there will be more and more public facilities and
infrastructure available for the resident. While developing the Greater Adelaide, the increasing of the
traffic will occur as the same.
As planned, more rail services will supply on the Noarlunga, it means the Oaklands Park rail crossing
will close more frequently. Then, the road will be overload running. To design a new traffic road
program is extremely urgent.
This tender details the feasibility of foreseeable works which are:
Redesign the existing road to cater satisfying 2021 traffic volumes. It requires integrating and altering
the existing road in order to service the busy traffic from 2021.
Choose suitable road sections to build the overpass. It is very important which need to consider two
aspects: it is better to avoid the high value for the slope of the bridge; and make sure do not make the
vehicles cannot access their destination or need to drive longer to access the destination caused by
overpass.
Overpass should be designed for the busier lanes.
Design the suitable pavement sections for the overpass construction. The software CIRCLY can be
used to analysis the sections.
During and after construction, need to consider how to allow pedestrian to across the intersection.
Speak to the local council to inform residents and businesses about this project for a period depends
on the final project plan prior to the start of the construction phase of the project.
Potential Impacts
Construction area may clash with allocated public transport routes, so it is necessary to come up with
a number of detour path plans to help this situation.
Trains maybe cannot crossing this area, it will affect resident to choose others vehicles to instead
Some points which are shown above maybe not need to be carried after the design, but they are
necessary to be considered as the feasibility study in this stage.
HEPTA CONSULTING 22
Structural Division
Major components
The major structural element in the Oaklands Park grade separation project consists of some
modifications of road to increase capacity and improve traffic flow and road and rail safety. Structural
elements in this project include any location that has access to a transportation network, and Physical
transport infrastructures that enable to connect two nodes. Also, the corridor could also be involved
that a sequence of nodes and links supporting modal flows of passengers or freight. They are generally
concentrated along a communication axis, have a linear orientation and usually serve a gateway.
Some minor structural work may be required for car parking, some traffic signals, and bus stop etc.
Moreover, if a road overpass or underpass is considered then service relocation will become
significant.
Potential issues
Some potential issues need to be considered about construction of a rail overpass at this location,
such as security and safety, pedestrian access across at Diagonal/Morphett Roads, and local vehicular
access to businesses and facilities. Also, installation of the rail overpass and greenway structure, as
well as modifications to the Diagonal Road / Morphett Road junctions will impact on some elements
of the local road network. In particular, modified access from Morphett Road to Murray Terrace and
Kildonan Road - both become left in / left out only, and railway Terrace closed with no direct access
to Diagonal Road – alternative access would be via First Avenue and Dunrobin Road. In addition,
existing uncontrolled pedestrian refuge crossing on Morphett Road (near Murray Terrace) will be
replaced with a nearby pedestrian activated (signalised) crossing.
HEPTA CONSULTING 23
Geotechnical Division
Geotechnical always been the first parameters causing project success or not, that’s why Hepta
Consulting always been aware on this part to ensure and provide the best Final Construction for client
that reach their requirement. Furthermore, Hepta Consulting is undefeated on the accuracy of all the
data need for Geotechnical by Investment.
Geotechnical Field & Working Process
For the Geotechnical Team in Hepta Consulting, identifying Soil properties around the Working
location would be the Very first step of Geotechnical Team. Once the Result comes out, our team will
start figure out the best solution for the Foundation, these data would be one of the reference for the
Depth of Foundation and Diameter of the pile. Base on the Accruement of data, taking Soil Sample
from current location necessary. Furthermore, Hepta consulting also being aware of not affecting
surrounding structure foundation, during the investment, affection of the foundation around the
Working area would be estimated as well.
Issue and Solution for Oakland Railway Station
Stability and avoid deformation of the Structure is the most important part for Geotechnical, except
choosing the suitable material from structural design, maxi sing the support from the foundation is
the other way to avoid cracking, deformation, all the failure that client would not like to see happen.
There a few Point Need to be invest to ensure the foundation would be prefect.
Soil Properties
As the Soul Properties around Oakland Railway Station is unknown, a reality soil sample in Oakland
will be taken by Borehole. Soil example would go over a role of experiment to found out the per cent
of every Element within the soil, thus the properties (Hardness, elasticity, swelling etc.) can be
determined. According to these soil properties, the best depth of the foundation could be found.
Underground Water
The Location of Oakland is Approach to the Sturt River which connect with Gulf st Vincent, corrosive
or insoluble salts might contains in the underground water around Oakland. However, this point need
to be ensure by the further land investment, Insoluble Salt will increase the Corrosion Reinforced
concrete. Furthermore, the Crystallization on the pipe by underwater, would cause a high pressure in
foundation, which might cause cracking on foundation pipe. Underground water can be pump out by
the mechanics belongs to Hepta Consulting. This Investment can ensure the foundation is safe and
reliable.
HEPTA CONSULTING 24
Mechanical Problem in Rock
Drilling and Blasting may be necessary if rock layer is under the construction site. Getting the suitable
Drill for different hardness layer, can ensure the drill hole for foundation would in good condition and
reach the requirement depth from calculation.
HEPTA CONSULTING 25
Environmental Division
Major Components
An EIS or Environmental Impact Statement is required by law before any construction can take place.
It is a paper that provides information about potential issues of a project and ways to avoid or
minimise these issues.
An EIS must detail the ‘purpose and need for action,’ which is the overlying problem and why the
project needs to be conducted. As well as a range of alternatives to the proposed action which will
include no action at all, reasonable alternatives and alternatives that have already been eliminated
from the study. There will be an analysis of all alternatives, which will be used to come up with a list
of ‘preferred’ alternatives.
An EIS requires a detailed description of the environment that is going to be affected by the project.
Specifically what parts of that environment will be impacted and the consequences of those impacts.
An EIS requires a detailed list and analysis of the environmental issues involved with each alternative.
Including but not limited to impacts to flora and fauna, historical impacts, pollution, social and
economic impacts as well as a cost analysis for each alternative.
An EIS must also detail true ownership and heritage of the land in question.
The EIS is not to be treated as final. If new environmental concerns come up during different stages
of the project they will be added.
Overall the EIS must be able to give an informed overview of all possible issues involved in the project
and alternatives to either avoid them all together or at least drastically reduce them.
The EIS must be used to easily show whether the project has a strong environmental backing and
whether it is feasible that it goes ahead.
Potential Impacts
Social and Commercial impacts
Effects on plants, wildlife and landscape
Pollution (contaminated material, noise, vibration and air)
Sustainability (waste, recycled materials and greenhouse gas emissions)
Water sensitive urban design elements are kept intact or improved
HEPTA CONSULTING 26
Social and Commercial Impacts
The Seaford rail crossing in question is surrounded by a populated suburban area, so it is very
important to take in to consideration the effects that the construction and operation of the project
will have on housing and local business.
Probably the most important issue involved in the project will be keeping the impact on local residents
and business as low as possible. Housing surrounds the Seaford rail line crossing on all sides as well as
a set of shops west of the crossing. Local residents will need to be able to easily access the area daily
to ensure that they can get to and from their homes without heavy delays.
The Environmental Team will be working closely with local business to ensure that no business will
need to close during construction. Businesses will be visited and surveys will be carried out to
understand how they operate and solutions to their queries will be gathered from this. Traffic will
need to be managed and detours utilised to allow people to use the businesses during construction.
All residents and businesses will receive a copy of the EIS and will be encouraged to ask questions on
how to ease their problems during the construction phase.
Pollution will have a big impact on both housing and local business, and will be discussed in more
detail in the section ‘Pollution (Contaminated Material, Noise, Vibration and Air).’
Effects on Plants, Wildlife and Landscape
The Seaford rail crossing and surrounding area have been severely modified leaving very little area for
plants and wildlife. The site is already heavily developed and has been stripped to make room for
roads, housing and, of course, the train station.
There is very little grass land - mainly large trees remain, mostly gum, scatter the area. An assessment
of the flora will need to be undergone to detect plant species in an effort to protect them. Any
endangered flora if avoidable will not be touched; if unavoidable will be relocated by professionals.
The removal of large trees will not happen where avoidable, but if it becomes unavoidable, 8 trees
will be planted in one’s place. Any endangered trees will be left untouched. Even though the plant life
is scarce it will be of high priority to keep the impact on plant life low. But it’s not enough to leave the
local ecosystem as untouched as possible; an effort will also be made to improve it, where possible.
The wildlife in the area is made up of predominantly birds, as well as perhaps some Koala and Possum
species. Working with the local council as well as a site investigation will show areas and types of
wildlife, which will be kept as untouched as possible, if need be animals will be appropriately relocated
by professionals and perhaps brought back after construction is complete, if feasible.
Pollution (Contaminated Material, Noise, Vibration and Air)
Noise and vibration levels will need to be addressed for both the construction phase and operation
phase of the project. During the construction phase noise and vibration will be caused by machinery
used on site and an increase in congestion from local traffic and public transport. Once the project is
HEPTA CONSULTING 27
in operation the noise and vibration from every day use is also a big issue as the landscape will have
changed and the area will not be running as it was before. Noise and vibration is important to be kept
at a minimum for the protection of workers, local residents, passer-by’s and for the safety of local
wildlife.
Air pollution will occur from machinery used in construction as well as all modes of transport in the
area, both public and private, in the form of emissions such as nitrogen gas, carbon dioxide, carbon
monoxide, nitrogen oxides and hydrocarbons. Dust particles will also be a bi-product of
construction/demolition and will have to be kept at low levels. Keeping air pollution low while the
project is in operation is also a big issue that will be addressed in the feasibility study.
If any contaminated materials lie in the area it will be of utmost importance to avoid moving them,
but if that becomes unavoidable a professional team will be brought in to quickly and safely remove
the threat. Clean up teams will also be utilised in case of spills or leaks of any kind of dangerous
substances.
Sustainability (Waste and Recycled Materials)
Demolition and construction will yield waste, it is unavoidable, whether that is hazardous, organic or
recyclable and because of this, appropriate measures must be taken in the disposition of said waste.
Wherever possible, organic and recyclable waste will be recycled and reused for other projects.
Hazardous waste will be kept to a minimum and safely removed by a carefully selected waste disposal
company.
As sustainability is a big feature at Hepta Consultants, recycled materials will be used wherever
possible in the construction of the project. Not only will this keep costs down, but it will lessen the
impact of the project on the environment.
Water Sensitive Urban Design Elements are Kept Intact or Improved
The Environmental Team will be working closely with both the Water and Utilities Teams to ensure
that the water sensitive design elements that are already in place in the area will not be affected too
much during the construction phase of the project.
Stormwater may have to be re-routed during construction and drains and pits may have to be
temporarily relocated. As this is the driest state on Earth, water efficiency is obviously a high priority.
Keeping water usage down during construction will be a main issue as careful planning will need to be
in place to ensure water losses will be kept at a minimum while stormwater systems and their
constituents are relocated. Urban planners will be utilised to not only reinstate the water sensitive
design elements already in place in the area after the construction is complete, but to improve them
in an effort to make them run more efficiently for the altered landscape.

Water Division
This part of the project deals with the changes that will occur to the existing water systems along the
construction site as well as introducing additional water systems for the constructed overpass.
Major Components
The water design part of the project will include a complete study of the following:
An introductory visual survey to observe the functionality and possible deficiencies of existing
drainage structures in the located area.
A more focused drainage study and survey
Hydrological survey analysis for the selected area
A complete stormwater analysis which includes: overland flow and reuse system as well as a flood
management and a treatment system.
Potential impacts
The new overpass will have a slight increasing effect on the total volume of stormwater runoff as the
existing roads have impervious surfaces.
Another concerning factor is the possible effects of the construction phase of the project on the water
supply and sewage systems in the area.
The project site (Seaford rail crossing) is surrounded by a populated suburban region. This means that
the water group should work closely with the environmental team to ensure that resident’s water
system associated needs are met during the course of the project and that possible negative effects
of our operation on the local environment in general is cut to minimum.
For example temporary water systems are put in place and a much improved and efficient water
system is developed by the end of the construction phase.
Strategies to achieve reduction of these issues involve:
Considering a major stormwater runoff treatment; whilst collaborating with the Environment team to
confirm that environmentally justified options are selected. Such options may include underground
storage which will be studied in detail.
Development of a strategy for an integrated Stormwater Management Plan.
Constructing water systems in accordance with hydraulic design of channels and structures with the
aid of modern computer modelling softwares such as DRAINS and HEC-RAS.
Consideration of Water Sensitive Urban Design (WSUD) principles and ethics.
To prevent negative environmental effects, Gross Pollutant Traps are used for contamination
avoidance.

Management Systems Division
Major components
A reasonable provision is necessary for bridge construction management. A good provision leads the
bridge construction work methodically. And major provision includes:
Traffic control management: the management of vehicles traveling. Arrange orderly vehicles traveling
or change to other road, in order to avoid accidents.
Road block management: the management of sign. The sign and signal must be clear. Make sure the
relative tool is not out of place.
Humanities management: The site position locates at the commercial and residential mixing zone. The
construction will bring the impact to this zone such as economic loss to the mall and noise pollution to
the resident.
Construction environmental management: the management of all environmental impacts caused by
the construction.
Environment monitoring: ensure that possible environmentally harmful actions are not undertaken
on the construction.
Security: the management of the protection of issues such as trespassing and terrorism in the
construction site.
To compile this provision, HC consulting must follow all necessary standards and laws, and make sure
all operations are executed efficiently and effectively.
The management provision and the level of adaptation are needed to be determined. And these things
will be revised and upgrade by experience learned from the process of construction.
Costing
The following cost developed by HC consulting is based on the potential issues and mitigation
processes and investigations as detailed above this document. The cost is calculated based on working
hours of each personnel with the assumption of 20 hour working weeks. The pay rate of employees is
based on the position of the personnel as well.
