The proposed area (bounded approximately by the red square in the picture below) currently consists of the IMAX Theatre and associated retail areas.

Figure 3.1. Proposed site

EWFW



4. Existing Infrastructure Services 4.1. SWC Water Main

The site is flanked by two (2) Sydney Water water mains. These mains are:

A 200mm DICL main located on the western end of the site (See Appendix 1 – Note 1)

A 150mm CICL dead leg capped main located on the eastern end of the site (See Appendix 1 – Note 2)

From the proposed footprint of the development both mains will be within the line of the building construction. It will be proposed to move the line of the water services to ensure they are diverted clear of the proposed building line. In addition to this, it is proposed that the 150mm and 200mm mains will be interconnected to extend the Sydney Water network within this region. This is in line with the requirements put forward by Sydney Water in their Letter of Feasibility for the site (Refer to Appendix 4).

4.2. SWC Sewer Main The site is flanked by several Sydney Water sewer mains and associated equipment. These include:

A 525 VC sewer main located at the eastern end of the site (See Appendix 1 – Note 3)

A 300 VC sewer main located at the southern end of the site (See Appendix 1 – Note 4)

A pump station and a vent shaft adjacent the site. This site pump station is also heritage listed.

Access chambers along both of the sewer mains nominated above

From the proposed footprint of the development both mains will be within the line of the building construction. It will be proposed to move the line of the sewer services to ensure they are diverted clear of the proposed building line. This is in line with the requirements put forward by Sydney Water in their Letter of Feasibility for the site (Refer to Appendix 4).

The Southern Lease Area of the proposed development (See Appendix 3) is located clear of the 750 VC sewer main (See Appendix 1 – Note 5). Further assessment will be conducted in conjunction with Structural Engineers as part of the design process to ensure that the proposed structure will have no impact on the service. This shall also be confirmed with Sydney Water as part of the Sydney Water Notice of Requirements.

4.3. SWC Stormwater Main As there are two significant stormwater mains running below the site there will be a protection requirement as part of the works. These mains include a set of culverts which traverse through the centre of the site in a north-south direction (known as the Hay Lackey Culverts) and a set which are located at the western side of the proposed development site.

The existing development currently sits above culverts and these will continue to be affected by the proposed development. Whilst the building footprint does not directly impinge the culverts at the western end of the site Sydney Water will be consulted in order to ensure all steps are taken to protect their adjacent assets.

Any works will be at the discretion of Sydney Water and their conditions as nominated.

4.4. Jemena Gas Main The site is flanked at the south-eastern corner and along the eastern boundary by Jemena gas infrastructure. This includes:

A 110mm Nylon main located at the eastern end of the site (See Appendix 2 – Note 1)

EWFW



A 50mm Nylon main located at the south-eastern end of the site (See Appendix 2 – Note 2)

A Secondary gas main (1050kPa) and a pressure reduction station located at the south-eastern end of the site (See Appendix 2 – Note 3)

Authority infrastructure to supply the Aquarium located at the south-eastern end of the site (See Appendix 2 – Note 4)

From the proposed footprint of the development both mains will be within the line of the building construction. It will be proposed to move the line of the gas services to ensure they are diverted clear of the proposed building line. These lines will run to the west and then the north of the building line, remaining clear of all adjacent supply authority infrastructure. This will be at the discretion of Jemena and their conditions nominated.

EWFW



5. Consideration of Authority Infrastructure 5.1. SWC Water Main

Sydney Water’s Letter of Feasibility has deemed that the adjacent water mains will be sufficient to satisfy the requirements of the proposed building. Sydney Water has nominated that the 150mm and 200mm water mains need to be relocated clear of the building line and interconnected. These works will be completed as part of the development. Subject to the final requirements set forth by Sydney Water, the building will be connected to the 200mm service.

A Sydney Water Co-ordinator will be engaged once the Development Application has been submitted. The Sydney Water Co-ordinator will provide the submission of a Section 73 Application to Sydney Water in order to obtain the Notice of Requirements for the development.

Works outlined within the Notice of Requirements will be undertaken by the Sydney Water Co-ordinator in accordance with Sydney Water’s Design Guidelines. Any works to the mains will be undertaken by Sydney Water approved contractors as nominated by the Water Co-ordinator.

5.2. SWC Sewer Main Sydney Water’s Letter of Feasibility has deemed that the adjacent sewer mains will be sufficient to satisfy the requirements of the proposed building. Sydney Water has nominated that the 525mm and 300mm sewer mains need to be relocated clear of the building line. These works will be completed as part of the development. Subject to the final requirements set forth by Sydney Water, the building will be connected to the 525 VC service through a connection at one of the adjacent access chambers.

A Sydney Water Co-ordinator will be engaged once the Development Application has been submitted. The Sydney Water Co-ordinator will provide the submission of a Section 73 Application to Sydney Water in order to obtain the Notice of Requirements for the development.

Works outlined within the Notice of Requirements will be undertaken by the Sydney Water Co-ordinator in accordance with Sydney Water’s Design Guidelines. Any works to the sewer mains will be undertaken by Sydney Water approved contractors as nominated by the Water Co-ordinator.

5.3. SWC Stormwater Main Presently we have commenced discussions with Jeya Jeyadevan and Raymond Parsell of the Sydney Water Stormwater Group. Several meetings have been undertaken to date in order to determine the requirements for any works which will affect the stormwater culverts, particularly the Hay Lackey culverts which traverse below the building line. Sydney Water has outlined the information they require which we will provided to Sydney Water as part of the Design Development.

Any direction or requirements provided by Sydney Water’s stormwater group in terms of construction over, or protection of these assets will be undertaken in strict accordance with the requirements nominated.

5.4. Jemena Gas Main Based on the initial site meeting with Anne Westwood and Andrew Lelliott of Jemena, the adjacent gas mains are running close to capacity. Jemena are in the process of reviewing their capabilities within the region and the strategy for supply to this area and the adjacent CBD. This will see additional supply within the region which will satisfy the supply required for the calculated building demand. Presently it is proposed that connection be made to the main located at the rear of the site (pending final gas diversion routes).

EWFW



Any direction or requirements provided by Jemena in terms of construction over, relocation or protection of these assets will be undertaken in strict accordance with the requirements nominated.

9. Appendix 4 – Sydney Water Letter of Feasibility

Case Number: 131752

11 April 2013

GROCON PTY LTDc/- BILLBERGIA PTY LTD

FEASIBILITY LETTER

Developer: GROCON PTY LTDYour reference: 3867Development: Lot 401 DP862501 DARLING HARBOUR Unset, SydneyDevelopment Description: The development comprises a 20 storey building component

of approximately 73,000sqm total Gross Floor Area plus anUrban Renewal / Landscape component of approximately10,000sqm. The total proposed site area for the developmentincluding the building footprint is 15,060sqm on, and adjacentto, the site currently occupied by the IMAX Cinema, DarlingHarbour, Sydney.

Dear Applicant

This Feasibility Letter (Letter) is a guide only. It provides general information about what SydneyWater’s requirements could be if you applied to us for a Section 73 Certificate (Certificate) foryour proposed development. The information is accurate at today’s date only.

If you obtain development consent for that development from your consent authority (this isusually your local Council) they will require you to apply to us for a Section 73 Certificate. Youwill need to submit a new application (and pay another application fee) to us for that Certificateby using your current or another Water Servicing Coordinator (Coordinator).

Sydney Water will then send you either a:• Notice of Requirements (Notice) and Developer Works Deed (Deed); or• Certificate.

These documents will be the definitive statement of Sydney Water’s requirements.

There may be changes in Sydney Water’s requirements between the issue dates of this Letterand the Notice or Certificate. The changes may be:

• if you change your proposed development, e.g. the development description or the plan/

SYDNEY WATER CORPORATION 2 Case No: 131752

site layout, after today, the requirements in this Letter could change when you submityour new application; and

• if you decide to do your development in stages then you must submit a new application(and pay another application fee) for each stage.

No warranties or assurances can be given about the suitability of this document orany of its provisions for any specific transaction. It does not constitute an approvalfrom Sydney Water and to the extent that it is able, Sydney Water limits its liability tothe reissue of this Letter or the return of your application fee. You should rely on yourown independent professional advice.

What You Must Do To Get A Section 73 CertificateTo get a Section 73 Certificate you must do the following things. You can also find out about thisprocess by visiting www.sydneywater.com.au > Building and Developing > Developing YourLand.

1. Obtain Development Consent from the consent authority for your developmentproposal.

2. Engage a Water Servicing Coordinator (Coordinator).

You must engage your current or another authorised Coordinator to manage the designand construction of works that you must provide, at your cost, to service your development.If you wish to engage another Coordinator (at any point in this process) you must write andtell Sydney Water.

For a list of authorised Coordinators, either visit www.sydneywater.com.au > Building andDeveloping > Developing Your Land or call 13 20 92.

The Coordinator will be your point of contact with Sydney Water. They can answer mostquestions that you might have about the process and developer charges and can give you aquote or information about costs for services/works (including Sydney Water costs).

3. Developer Works Deed

After the Coordinator has submitted your new application, they will receive the SydneyWater Notice and Developer Works Deed. You and your accredited DeveloperInfrastructure Providers (Providers) will need to sign and lodge both copies of the Deed withyour nominated Coordinator. After Sydney Water has signed the documents, one copy willbe returned to the Coordinator.

The Deed sets out for this project:

• your responsibilities;

• Sydney Water’s responsibilities; and

• the Provider’s responsibilities.

You must do all the things that we ask you to do in that Deed. This is because yourdevelopment will have an impact on existing water, sewer and storm water services and youmay be required to adjust/deviate these assets and pay for the following works under thisDeed to provide these services.

Note: The Coordinator must be fully authorised by us for the whole time of the agreement.

4. Water and Sewer Works

4.1 Water

Your development must have a frontage to a water main that is the right size and can be

19


used for connection.

Sydney Water has assessed your application and found that:

There is sufficient trunk capacity to service your development.

Adjustments will be required to the existing DN150 water main currently supplying the IMAXTheatre and the DN 200 water main that loops through Tumberlong Park to accommodatethe proposed development footprint.

A link main will need to be constructed between the two existing aforementioned DN150 andDN200 water mains to provide a point of connection with adequate capacity for domestic andcommercial services.

Fire services have not been assessed as part of this application. Sydney Water provides noguarantee that the proposed infrastructure will have sufficient capacity for fire services –Refer to Fire Fighting in ‘Other Things You Need to Do or Know’ below.

These works must be constructed by a constructor with the appropriate capability. YourCoordinator will be able to provide further advice about this.

4.2 Sewer

Your development must have a sewer main that is the right size and can be used forconnection. That sewer must also have a connection point within your development'sboundaries.

Sydney Water has assessed your application and found that:

There is sufficient trunk capacity for the proposed development.

Adjustments to the existing DN525 & DN300 sewer mains will be required to accommodatethe proposed development footprint.

A Sewer main extension will be required if the point of connection is remote from theproperty boundary.

The terms of the Deed define this extension as ‘Major Works’.

4.3 Stormwater Requirements.

Sydney Water has assessed your application and found that indicatively:

• The proposed development is in close proximity to existing Sydney Water stormwaterassets.

• There is insufficient information / clarity within the submitted documentation to facilitate aclear understanding of the potential impacts of the proposed development on SydneyWater stormwater assets or the potential impacts of the proposed development on local

20


flooding.

• The applicant is requested to provide a Stormwater Impacts Report to assist SydneyWater in the assessment of the proposed development and the formulation of furtherrequirements related to Stormwater.

o The Stormwater Impacts Report is to be prepared by a suitably qualified andexperienced person (Water Servicing Coordinator to verify) with access to thecurrent Sydney Water GIS Asset Database (Hydra) via the lodging WaterServicing Coordinator.

o Any component of the proposed development within 10 metres of an existingSydney Water stormwater asset is to be clearly identified by the Water ServicingCoordinator in plan and described / itemised in the report.

On receipt of a suitable Stormwater Impacts Report, as part of either a new feasibility applicationor Section 73 Compliance application, Sydney Water shall issue further requirements related tostormwater.

Approval for any element of the proposed development that is within 10 metres of an existingSydney Water stormwater asset shall not be inferred, notwithstanding the content of anydocumentation provided to date, unless specifically approved in writing by Sydney Waterfollowing receipt and review of a suitable Stormwater Impacts Report.

• In general terms the proposed development is required to meet the followingrequirements:

o Where an existing structure is already placed in, on or near the stormwater assetin a manner that interferes with the operation of or accessibility to the asset andthe structure is to be demolished then any replacement structure shall generallynot be installed in a similar configuration / footprint without the writtenconcurrence of Sydney Water.

o Sydney Water will consider on merit any proposal to reinstate a replacementbuilding or structure in a similar configuration / footprint.

o No new structure is to be placed in, on or near the stormwater asset in a mannerthat interferes with the operation of or accessibility to the asset.

o Sydney Water would consider a proposal to deviate / relocate an existing SydneyWater stormwater asset to facilitate an improved development outcome.

o The development is to be configured and include any necessary design elementsor works to ensure that local flood risks are suitably managed and appropriatelymitigated. The proposed development shall incorporate sufficient floodmanagement elements to ensure that the development shall not increase floodrisks to the community nor shall there be any potential for increased communityexpectation or demand for stormwater asset amplification to be undertaken bySydney Water in the future.

21


o A detailed 2D flood study will be submitted describing flood extents, velocities anddepths for a range of events (5yr, 20yr, 100yr) and provisional hydraulic andhazard categories (low and high).

o The proposed development will need to demonstrate a best practice approach tomanaging people and property in high flood hazard areas.

If the proposed development is required to discharge stormwater into Sydney Water’sstormwater channel, then a separate application is to be forwarded to Sydney Water.

All stormwater connections should comply with Sydney Water’s On-Site Detention policy andconnection requirements. For further details please contact Sydney Water’s StormwaterTeam on (02) 8849 4459 (or fax (02) 8849 3063)

5. Ancillary Matters

5.1 Asset adjustments

After Sydney Water issues this Notice (and more detailed designs are available), SydneyWater may require that the water main/sewer main/stormwater located in the footway/yourproperty needs to be adjusted/deviated. If this happens, you will need to do this work as wellas the extension we have detailed above at your cost. The work must meet the conditions ofthis Notice and you will need to complete it before we can issue the Certificate. SydneyWater will need to see the completed designs for the work and we will require you to lodge asecurity. The security will be refunded once the work is completed.

5.2 Entry onto neighbouring property

If you need to enter a neighbouring property, you must have the written permission of therelevant property owners and tenants. You must use Sydney Water’s Permission to Enterform(s) for this. You can get copies of these forms from your Coordinator or the SydneyWater website. Your Coordinator can also negotiate on your behalf. Please make sure thatyou address all the items on the form(s) including payment of compensation and whetherthere are other ways of designing and constructing that could avoid or reduce their impacts.You will be responsible for all costs of mediation involved in resolving any disputes. Pleaseallow enough time for entry issues to be resolved.

5.3 Costs

Construction of these future works will require you to pay project management, survey,design and construction costs directly to your suppliers. Additional costs payable toSydney Water may include:• water main shutdown and disinfection;• connection of new water mains to Sydney Water system(s);• design and construction audit fees;• contract administration, Operations Area Charge & Customer Redress prior to project

finalisation;

22


• creation or alteration of easements etc; and• water usage charges where water has been supplied for building activity purposes prior

to disinfection of a newly constructed water main.

Note: Payment for any Goods and Services (including Customer Redress) provided bySydney Water will be required prior to the issue of the Section 73 Certificate orrelease of the Bank Guarantee or Cash Bond.

Your Coordinator can tell you about these costs.

6. Stamping and Approval of your Building Plans

You must have your building plans stamped and approved before the Certificate can beissued. Building construction work MUST NOT commence until Sydney Water hasgranted approval. Approval is needed because construction/building works may affectSydney Water’s assets (e.g. water and sewer mains).

Your Coordinator can tell you about the approval process including:• Your provision, if required, of a “Services Protection Report” (also known as a “peg-out”).

This is needed to check whether the building and engineering plans show accuratelywhere Sydney Water’s assets are located in relation to your proposed building work.Your Coordinator will then either approve the plans or make requirements to protectthose assets before approving the plans;

• Possible requirements;• Costs; and• Timeframes.

You can also find information about this process (including technical specifications) if youeither:• visit www.sydneywater.com.au > Building and Developing > Building and Renovating.

Here you can find Sydney Water’s Guidelines for Building Over/Adjacent to SydneyWater Assets; or

• call 13 20 92.

Notes:• The Certificate will not be issued until the plans have been approved and, if

required, Sydney Water’s assets are altered or deviated;• You can only remove, deviate or replace any of Sydney Water’s pipes using

temporary pipework if you have written approval from Sydney Water’s UrbanGrowth Business. You must engage your Coordinator to arrange this approval;and

• You must obtain our written approval before you do any work on Sydney Water’ssystems. Sydney Water will take action to have work stopped on the site if you donot have that approval. We will apply Section 44 of the Sydney Water Act 1994.

23


OTHER THINGS YOU MAY NEED TO DO OR KNOWShown below are other things you need to do that are NOT a requirement for the Certificate.They may well be a requirement of Sydney Water in the future because of the impact of yourdevelopment on our assets. You must read them before you go any further.

Individual metering of units

All multi-level unit developments now have the option (not mandatory) to prepare their building’splumbing for individual unit metering. For more information visit www.sydneywater.com.au >Plumbing > Meters and look at our �ulti�level�individual��etering�guide� It is important that youunderstand that this will become mandatory from late 2013 and that you should consider this inplanning your development.

Disused Sewerage Service Sealing

Please do not forget that you must pay to disconnect all disused private sewerage services andseal them at the point of connection to a Sydney Water sewer main. This work must meetSydney Water’s standards in the NSW Code of Practice for Plumbing and Drainage (the Code)and be done by a licensed drainer. The licensed drainer must arrange for an inspection of thework by a NSW Fair Trading Plumbing Inspection Assurance Services (PIAS) officer. After thatofficer has looked at the work, the drainer can issue the Certificate of Compliance. The Coderequires this.

Soffit Requirements

Please be aware that floor levels must be able to meet Sydney Water’s soffit requirements forproperty connection and drainage.

Requirements for Business Customers for Commercial and Industrial PropertyDevelopments

If this property is to be developed for Industrial or Commercial operations, it may need to meetthe following requirements:

Trade Wastewater Requirements

If this development is going to generate trade wastewater, the property owner must submit anapplication requesting permission to discharge trade wastewater to Sydney Water’s seweragesystem. You must wait for approval of this permit before any business activities can commence.

The permit application should be emailed to Sydney Water’s Business Customer Services [email protected]

It is illegal to discharge Trade Wastewater into the Sydney Water sewerage system withoutpermission.

A Boundary Trap is required for all developments that discharge trade wastewater wherearrestors and special units are installed for trade wastewater pre-treatment.

24


If the property development is for Industrial operations, the wastewater may discharge into asewerage area that is subject to wastewater reuse. Find out from Business Customer Services ifthis is applicable to your development.

Backflow Prevention Requirements

Backflow is when there is unintentional flow of water in the wrong direction from a potentiallypolluted source into the drinking water supply.

All properties connected to Sydney Water's supply must install a testable Backflow PreventionContainment Device appropriate to the property's hazard rating. Property with a high ormedium hazard rating must have the backflow prevention containment device tested annually.Properties identified as having a low hazard rating must install a non-testable device, as aminimum.

Separate hydrant and sprinkler fire services on non-residential properties, require the installationof a testable double check detector assembly. The device is to be located at the boundary of theproperty.

Before you install a backflow prevention device:1. Get your hydraulic consultant or plumber to check the available water pressure versus

the property’s required pressure and flow requirements.2. Conduct a site assessment to confirm the hazard rating of the property and its services.

Contact PIAS at NSW Fair Trading on 1300 889 099.

For installation you will need to engage a licensed plumber with backflow accreditation who canbe found on the Sydney Water website:http://www.sydneywater.com.au/Plumbing/BackflowPrevention/

Water Efficiency Recommendations

Water is our most precious resource and every customer can play a role in its conservation. Byworking together with Sydney Water, business customers are able to reduce their waterconsumption. This will help your business save money, improve productivity and protect theenvironment.

Some water efficiency measures that can be easily implemented in your business are:• Install water efficiency fixtures to help increase your water efficiency, refer to WELS

(Water Efficiency Labelling and Standards (WELS) Scheme, http://www.waterrating.gov.au/

• Consider installing rainwater tanks to capture rainwater runoff, and reusing it, where costeffective. Refer to http://www.sydneywater.com.au/Water4Life/InYourBusiness/RWTCalculator.cfm

• Install water-monitoring devices on your meter to identify water usage patterns and leaks.• Develop a water efficiency plan for your business.

It is cheaper to install water efficiency appliances while you are developing than retrofitting themlater.

25


Contingency Plan Recommendations

Under Sydney Water's customer contract Sydney Water aims to provide Business Customerswith a continuous supply of clean water at a minimum pressure of 15meters head at the maintap. This is equivalent to 146.8kpa or 21.29psi to meet reasonable business usage needs.

Sometimes Sydney Water may need to interrupt, postpone or limit the supply of water servicesto your property for maintenance or other reasons. These interruptions can be planned orunplanned.

Water supply is critical to some businesses and Sydney Water will treat vulnerable customers,such as hospitals, as a high priority.

Have you thought about a contingency plan for your business? Your Business CustomerRepresentative will help you to develop a plan that is tailored to your business and minimisesproductivity losses in the event of a water service disruption.

For further information please visit the Sydney Water website at: http://www.sydneywater.com.au/OurSystemsandOperations/TradeWaste/ or contact BusinessCustomer Services on 1300 985 227 or [email protected]

Fire Fighting

Definition of fire fighting systems is the responsibility of the developer and is not part of theSection 73 process. It is recommended that a consultant should advise the developer regardingthe fire fighting flow of the development and the ability of Sydney Water’s system to provide thatflow in an emergency. Sydney Water’s Operating Licence directs that Sydney Water’s mains areonly required to provide domestic supply at a minimum pressure of 15 m head.

A report supplying modelled pressures called the Statement of Available pressure can bepurchased through any Quickcheck agent and may be of some assistance when defining the firefighting system. The Statement of Available pressure, may advise flow limits that relate tosystem capacity or diameter of the main and pressure limits according to pressure managementinitiatives. If mains are required for fire fighting purposes, the mains shall be arranged throughthe water main extension process and not the Section 73 process.

Large Water Service Connection

A water main will be available, once you have completed your drinking water main constructionto provide your development with a domestic supply. The size of your development means thatyou will need a connection larger than the standard domestic 20 mm size.

To get approval for your connection, you will need to lodge an application with a Quick CheckAgent. You, or your hydraulic consultant, may need to supply the following:

• A plan of the hydraulic layout;• A list of all the fixtures/fittings within the property;• A copy of the fire flow pressure inquiry issued by Sydney Water;

26


• A pump application form (if a pump is required);• All pump details (if a pump is required).

You will have to pay an application fee.

Sydney Water does not consider whether a water main is adequate for fire fighting purposes foryour development. We cannot guarantee that this water supply will meet your Council’s firefighting requirements. The Council and your hydraulic consultant can help.

Disused Water Service Sealing

You must pay to disconnect all disused private water services and seal them at the point ofconnection to a Sydney Water water main. This work must meet Sydney Water’s standards inthe NSW Code of Practice for Plumbing and Drainage (the Code) and be done by a licensedplumber. The licensed plumber must arrange for an inspection of the work by a NSW FairTrading Plumbing Inspection Assurance Services (PIAS) officer. After that officer has looked atthe work, the drainer can issue the Certificate of Compliance. The Code requires this.

Other fees and requirementsThe requirements in this Notice relate to your Certificate application only. Sydney Water may beinvolved with other aspects of your development and there may be other fees or requirements.These include:

• plumbing and drainage inspection costs;• the installation of backflow prevention devices;• trade waste requirements;• large water connections and• council fire fighting requirements. (It will help you to know what the fire fighting

requirements are for your development as soon as possible. Your hydraulic consultantcan help you here.)

No warranties or assurances can be given about the suitability of this document or any ofits provisions for any specific transaction. It does not constitute an approval fromSydney Water and to the extent that it is able, Sydney Water limits its liability to thereissue of this Letter or the return of your application fee. You should rely on your ownindependent professional advice.

Meeting Minutes EWFW

- Dilapidation reporting - Maintenance and access requirements and potential methods for replacing the stormwater in the future

o A Flood Study outlining: - Overland flow paths for existing and proposed - Capacity assessments - Impacts associated with the stormwater and the proposed buildings

JJ noted that the existing culverts are 3.9m x 2.2m and 3.0m x 2.2m and they have been sized using the rational method for a 100 year capacity

JJ is happy to allow access to any information SW has available and copies can be made of existing information. There may be a condition report for the culverts. JJ can be approached to find further information however the SW contact who would be aware of this information is currently on holidays for 2 weeks

RP noted that the main issues in which SW would not allow any construction is if there are overland flow path and flooding issues that can’t be rectified or if the assets could not be cost effectively renewed in the future

RP noted that a decision would be made a couple of weeks after all of the above information was available to SW

Issues for Resolution

EWFW to provide information on Dilapidation Contractor used for previous project to GG GB to confirm if these works are covered under Bonacci Contract In the event that Bonacci are not providing Flood Study EWFW to provide details to have Flood

Study conducted All services will be required to provide information for the Deviation Report as required
