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 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


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.
