ENGINEERING GUIDE FOR DEVELOPMENT

2005

FOREWORD This Guide, and its accompanying document, Council's Work Specification - Civil, have been prepared to provide engineering guidelines for the subdivision and development of land within the Blacktown City Council area.

The aim of the Guide is to facilitate the efficient processing of engineering plan submissions, and to ensure that infrastructure associated with any development is designed and constructed to be safe, serviceable, economical to maintain and meets community expectations.

Applicants should be aware that each development is required to be treated on its merits, and that approval is dependant on the overall impact of the development and not solely on compliance with minimum engineering standards.

Nothing in this Guide is to be construed as limiting, in any way, Council's rights to impose differing conditions when approving development proposals, nor limiting the discretion of Council's Co-ordinator Engineering Approvals or his nominated representative to vary any necessary engineering requirements in respect of a particular development, having regard to good engineering practice.

Council wishes to acknowledge the assistance freely given by other Councils, Consultants and Contractors who suggested matters that required updating, new processes and products that may be adopted or provided assistance in this latest revision to ensure that this document represents current "best practice".

ENGINEERING GUIDE FOR DEVELOPMENT - February 2005

1 - 1

1. GENERAL PROCEDURES 1.1 Scope This section of the Engineering Guide sets out Council's general procedures

and practices in respect of engineering requirements for subdivision and development of land within the Council area.

1.2 Aim To provide an Applicant with an outline of Council's engineering procedures

for subdivisions and developments. 1.3 Engineering Plans, Inspections & Accredited Certifiers In this Guide, whenever the term "Engineering Plan" is used, this is deemed to

also be a reference to engineering plans associated with Construction Certificates issued by Council or Private Accredited Certifiers under the EP&A Act 1979, and Engineering Approvals issued by Council under the Roads Act 1993 and Local Government Act 1993.

Private Accredited Certifiers may issue Construction and Compliance

Certificates for subdivision and development works in accordance with the requirements of the EP&A Act 1979. Therefore any reference made in this Guide to approvals or inspections by Council’s Engineers or Development Supervisors for works under the EP&A Act 1979 shall also be deemed to be a reference to certificates issued and inspections carried out by Private Accredited Certifiers under the EP&A Act 1979.

Private Accredited Certifiers do not have any authority to issue Engineering

Approvals or carry out inspections for works on Public Roads under the Roads Act 1993.

It should also be noted that Construction Certificates cannot be issued for

works on sites that are not part of the "subject land" for which the Development Consent has been issued.

An example is interallotment drainage through adjacent lots that are not

included in the "subject land". In this case, a separate Section 68 Local Government Act 1993 Approval would be required for the drainage works. This form of approval can only be issued by Council.

Private Accredited Certifiers have no authority to vary the requirements of this

Guide. They must comply with all of the Guide’s requirements prior to issuing any Construction or Compliance Certificates under the EP&A Act 1979.



1 - 2

1.4 Overview of Engineering Process for the Applicant This section of the Guide sets out the suggested steps an Applicant should

follow once a Notice of Determination giving Development Consent to a development has been issued by Council. All other steps required prior to issue of consent can be found in Blacktown Development Control Plan 1992.

A. Read Notice of Determination (Development Consent): Where you are unsure of the meaning or extent of any condition,

contact the Council and seek clarification. (Development Consent No./File No. will help in this instance.)

Note: Construction Certificates cannot be issued until all Pre-

Construction Certificate requirements/conditions of the Development Consent have been satisfied.

B. Engage an Engineering Consultant/Project Manager: Satisfy yourself that the consultant has the required expertise and do

not decide on your consultant simply on the basis of fees. A higher fee may result in substantial savings in approval time/construction costs due to the consultant's expertise.

C. Give the consultant a copy of the whole of the Notice of

Determination: Any approved plans or other documents should also be given to the

consultant so he/she can fully understand the project. D. Let the consultant do the work: Once the consultant has been engaged, Council's officers will have

only one contact who is co-ordinating the progress of your development. Time delays often arise where inexperienced Applicants try to share the project management role.

E. Engineering plans are prepared by the consultant:.

The consultant is to arrange survey and engineering designs that will fulfil the conditions of consent. These plans, when approved, will be used by the contractor to construct the works.



1 - 3

F. Lodge Engineering Plans with Council for approval and pay assessment and inspection fees:

Lodge Engineering Plans, together with any other documents

/calculations/information and/or any clearances from government authorities required to satisfy the conditions of consent. Council's Engineer will provide a quote for the engineering fees. Once this is accepted, Council's Engineer will assess the Engineering Plans to ensure compliance with conditions of consent and other Council requirements.

G. Engineering plans returned to consultant for amendment (if

required): The Consultant will be advised if any amendments are required to the

Engineering Plans, and if any other outstanding items are required prior to the release of approved Engineering Plans.

H. Engineering plans relodged with Council: The Consultant should have carried out all the amendments required by

Council. If the consultant needs clarification of any requirements, Council's Engineers are available for discussion. The Consultant must also ensure that Council's "Red Mark Up" Plan (showing required corrections) is returned to Council with the amended plans. This will expedite their assessment.

I. Engineering plans approved: When Council is satisfied that the engineering plans will enable work

to be constructed with a minimum of field supervision the plans are approved and issued in accordance with the Consent conditions.

J. Construction of Works: The Consultant/Applicant will engage a contractor to carry out the

works in accordance with the approved plans. Council's Engineer or Development Supervisor will inspect the work to ensure the contractor carries the work out in accordance with the approved plans and with Council's "Works Specification - Civil".

K. Lodge Works-As-Executed Plan: Together with any Hydraulic (OSD), Structural or Compliance

Certificates, prior to requesting the final inspection.



1 - 4

L. Preliminary final inspection: When the Applicant considers that the works to be complete, Council's

Engineer/Supervisor will inspect the work and any defects will be brought to the Applicant's attention for rectification.

M. Final inspection: When all the defects, identified in the Preliminary Final Inspection, are

rectified the Applicant shall request a Final Inspection. Council's Engineer/Development Supervisor will reinspect the work to confirm that all the defects have been rectified.

N. Check Notice of Determination Before requesting the issue of a Subdivision Certificate (in the case of

subdivisions) or in other cases prior to the issue of an Occupation Certificate for the development, the development consent must be checked in detail. The Consultant/Applicant must ensure all conditions have been satisfied including, but not limited to:

* Compliance with all engineering conditions required by the

Development Consent, * Payment of fees and contributions, * Lodgement of completed Deed of Agreement for bonded

works, * Lodgement of certificates required by the Works Specification, * Lodgement of a Works-As-Executed Plan, and * Lodgement of Hydraulic & Structural certificates. O. Issue of Subdivision Certificate/Occupation Certificate: When all engineering conditions of consent have been satisfied and the

plan of subdivision and accompanying legal documents are correct, Council's Engineer for the project will recommend release of the plan of subdivision. The plan will only be released by Council if all conditions of consent have been satisfied and/or securities have been established for outstanding works.

P. Defects Liability/Maintenance Period: (a) Subdivisions: Upon the issue of a Subdivision Certificate the

constructed civil engineering work will enter the Maintenance Period. During this period any defect which becomes evident will be the responsibility of the Applicant to rectify. The



1 - 5

Maintenance Period lasts for at least 12 months from the issue of the Subdivision Certificate. At the end of the Maintenance Period, after any defects have been rectified, the Bond will be released and Council will issue an "Acceptance of Works" Certificate.

(b) All Other Development: Upon a clearance at the Final

Inspection (Step M) the constructed work will come under a Maintenance Period of at least 12 months. At the end of this period and upon rectification of any defects that become evident during that period, Council will issue an "Acceptance of Works" Certificate.

Q. Completion of Project: When all bonded works have been satisfactorily completed Council

will, upon request, release all securities held over the works. In the case of Path Paving Bonds in subdivisions, 2 years or more can elapse between the "Acceptance of Works" and the release of the bond. Council provides the Applicant with the option of making a monetary payment for the works rather than be burdened with a long-term bond in accordance with Council's Path Paving Policy (January 2001). In this event, Council will use the Monies to construct the path paving when building activities are finalised and when damage is less likely.

This monetary payment is based on the costs set out in Council's

Goods and Services Pricing Schedule. These costs include a provision for the delay in construction and are updated every year.

1.5 Engineering Survey & Bench Marks The engineering survey shall be carried out using the ISG co-ordinate

reference system and all levels shall be on Australian Height Datum (A.H.D.). The Co-ordinator's approval shall be obtained if another datum is to be adopted.

The survey shall accurately show the landform to facilitate the best possible

design and construction of road works and drainage consistent with minimum interference to the existing amenity of the area.

Bench Marks shall be established at intervals not greater than 600 metres and

are to be placed where they will not be disturbed. This requirement may be waived by the Co-ordinator where State Survey Marks exist. One copy of each locality sketch shall be submitted to Council at the same time as the final Plan of Subdivision (Subdivision Certificate).



1 - 6

1.6 Engineering Drawings Engineering Drawings shall be submitted in triplicate, with a covering letter,

by the Consultant. One set of approved plans will be returned to the Consultant with an approval letter. It is suggested that one (1) set of plans be submitted for an initial check by Council's Engineers, followed by the submission of the full set upon completion of any amendments required by Council.

The preparation of engineering drawings for developments and subdivisions

shall be carried out in accordance with Section 2 - "Engineering Drawings", of this Guide.

The civil engineering drawings will be checked by Council's Engineers for

compliance with these guidelines. It is the responsibility of the Consultant to ensure that the designs, calculations and specifications comply with Consent Conditions, this Guide, relevant Australian Standards and other Council Codes. Approval of the drawings does not relieve the Applicant from rectifying any errors or omissions which become evident during construction or the liability period.

The Applicant is required to comply with Council's current standards and if

work has not substantially commenced within two (2) years of the date of the endorsed approval, the Co-ordinator may require that revised engineering drawings, calculations and specifications be submitted for a renewed approval.

1.7 Persons Qualified Unless stated otherwise in this Guide, Council requires that design plans be

prepared to Council's standards by a person either holding qualifications acceptable for Corporate Membership of the Institution of Engineers Australia or approved by the Co-ordinator and/or who has proven experience in the preparation of plans and specifications for land development.

1.8 Consultation Designers are encouraged to consult with Council and other relevant

authorities during the preparation of design plans. 1.9 Inspection of Works All road and drainage works carried out by the Applicant that will become part

of Council's infrastructure, are to be inspected by Council's Engineers and Development Supervisors in accordance with Council's Works Specification - Civil.



1 - 7

In addition to all engineering works associated with land subdivisions, Council's Engineers and Development Supervisors will also approve and carry out inspections for road and drainage works on Public Roads, On-site Stormwater Detention Systems, Interallotment Stormwater Drainage Lines, WSUD features, Stormwater Quality Improvement Devices, Stormwater flow paths and channels, and Community Title/ Private Access Roads.

A separate application shall be submitted to Council in respect of footway and

gutter crossings and inspections shall be arranged with Council's Maintenance Section.

1.10 Tree Preservation Applicants are advised that NO trees shall be removed without Council's

permission. The Applicant shall provide a tree survey plan detailing the trees to be retained and clearly defining any trees proposed for removal.

The following Tree Preservation Order applies to the City: Blacktown City Council Tree Preservation Policy is covered by Clause 25

of the Blacktown Local Environmental Plan 1988. "Tree Preservation 25. (1) A person shall not ringbark, cut down, lop, top, remove, injure

or wilfully destroy any tree, or cause any tree to be ringbarked, but down, topped, lopped, removed, injured or wilfully destroyed, except with the consent of the Council.

(2) In any proceedings for an offence arising under this Clause, it

shall be sufficient defence to prove that the tree ringbarked, cut down, topped, lopped, removed, injured or wilfully destroyed, was dying or dead or had become dangerous.

(3) This clause does not apply to trees in State forest or on land

reserved as a timber reserve within the meaning of the Forestry Act 1916, or to trees required to be lopped in accordance with Regulation 38 or 29 of the Overhead Line Construction and Maintenance Regulations 1962, or to any trees which are under the control or management of Sydney Water.

(4) This clause does not operate so as to require a consent to be

given pursuant to this clause for the carrying out of development at a plant nursery if the development could be lawfully carried out at the plant nursery in the absence of this clause."



1 - 8

Council may require Applicants to lodge a Tree Bond to ensure trees are not damaged or removed during the construction of works.

Engineering Plans must bear the following note: Prior to the commencement of any earthworks, and after the road centrelines

have been pegged and/or permanently marked, the site must be inspected by Council's representative and the Applicant's representative to identify and appropriately mark:

(a) The trees to be retained. (b) All trees to be left undisturbed and cordoned off. All trees to be retained are to be protected by paraweb fencing, firmly staked

four (4) metres from the trunk of the tree. This fencing is to be erected prior to the commencement of any site works and is to be maintained in position for the duration of the works. The area within the drip line of the tree should not be used for the stockpiling of new or demolition material, nor for vehicular or pedestrian convenience or uses that would compact the soil in this area.

1.11 Street Trees Where the Applicant proposes to plant street trees in lieu of the Section 94

Tree Contribution, or proposes to landscape roundabouts and medians, works must be carried out in accordance with the requirements set out in Council's "Tree Planting Study". The Applicant must obtain written agreement from Council prior to proceeding with these works.

1.12 Erosion and Sediment Control All developments, where the site is disturbed, shall provide Erosion and

Sedimentation Control in accordance with the requirements of the NSW Department of Environment and Conservation, and Council.

Design plans shall be in accordance with the NSW Department of

Environment and Conservation Guidelines, Landcom's "Managing Urban Stormwater - Soil and Construction - Volume 1" 4th Edition (2004), and Section 5.14 of this Guide.

1.13 Road Safety Audit and OH&S Requirements Consultants preparing Engineering Plans must carry out a road safety audit of

the site, drawings and associated documents to ensure that all the requirements as set out in Austroad's "Road Safety Audit" Manual, Second Edition 2002, have been satisfied.



1 - 9

It is the responsibility of the Consultant/Designer to ensure that they have

addressed all relevant Occupational Health & Safety concerns, including but not limited to Traffic Management Plans for works on Public Roads, and Confined Spaces Act requirements for SQIDs and OSD storages.

1.14 Bonds 1.14.1 General

Council's Development procedures provide for the lodgement of bonds where it is impractical to complete certain aspects of the infrastructure work or where it is necessary to defer construction until building activities have been substantially completed. All bonds must be in accordance with Council's Standard format (see Appendix "E").

Bond amounts will be provided upon request. Upon written request from the Applicant and satisfactory completion of the Maintenance Period, or the works (whichever is the case), the Bond or any amount remaining will be released by Council.

1.14.2 Path Paving

Path paving construction in accordance with Council's Path Paving Policy (see Appendix "C") shall be deferred for a period following practical completion of the road works.

Two options are available to the Applicant:-

* Bond the Works, by lodging an appropriate security with a

Deed of Agreement. * Monetary Payment, where Council will use the monies for

construction of paths at a later, appropriate time.

1.14.3 Maintenance

Prior to the issue of a Subdivision Certificate (for subdivisions) or at practical completion of works (for other developments), a Bank Guarantee or Cash Security, to the amount of 5% (with a minimum amount of $5,000) of the value of the whole of the works to be constructed, must be lodged with Council. This is to provide for the satisfactory performance of works and the replacement of any failed or unsatisfactory work and any repairs required, inclusive of the maintenance of any traffic control facilities.



1 - 10

The bond will be held by the Council for a period of at least 12 months from the date of issue of the Subdivision Certificate/release of the Plan of Subdivision or the date of completion of the works, whichever is the latter. During this time the Applicant is responsible for maintenance of the works. Any failure on his behalf may lead to call-up of all or part of the security to enable remedial works to be undertaken by Council.

1.15 Contributions/Monetary Payments Contributions and/or monetary payments for certain outstanding items must be

lodged prior to the issue of the Subdivision Certificate, or upon practical completion of ½ width road works associated with developments as detailed in the Consent.

1.15.1 A.C. Sealing

Subdividers are required to lodge a cash payment to cover the cost of the final 25mm layer of Asphaltic Concrete (A.C.) following installation of services by the various authorities. Such payment is assessed by Council after submission of Work-As-Executed plans and is based on Council's current construction rates.

1.15.2 Street Trees A cash contribution in accordance with Section 94 (EP&A Act) Contributions Plan No.10 is required in respect of each new lot towards Council's provision of street trees at a suitable time in the development of the area.

1.15.3 Path Paving

3. ROAD DESIGN 3.1 Scope This section of the manual sets out Council's requirements for the design of

urban and rural roads. It is in no way a comprehensive design manual and it is intended to be read in conjunction with and as a supplement to:

* AUSTROADS (2009) - Guide to Traffic Management * AUSTROADS (2009) – Guide to Road Design- suite of design

manuals- as amended * AUSTROADS (2012) – Guide to Pavement Technology – Part 2

Pavement structural Design * ARRB, Transport Research (1995) Sealed Local Roads Manual -

Guidelines to Good Practice for the Construction, Maintenance and Rehabilitation of Pavements,

* AMCORD - A National Resource Document for Residential Development,

* Department of Housing Road Manual, and * Council's relevant Development Control Plans. 3.2 Aim The design and construction of a road system that provides the following: * a high level of safety for all users, * acceptable levels of amenity and protection from the impact of traffic, * a reasonable level of convenience for all users, and * economy of construction and maintenance. 3.3 Planning Standards The road hierarchy has been developed to cater for various functions that need

to be performed by roads within Council's road network. The road hierarchy and relevant road widths are listed in table 3.1 of this Guide and are also embodied in Council's Blacktown Development Control Plan 2006 (Part A).

New road layouts and widths must conform to that shown in Table 3.1 and any

other relevant Development Control Plans. The precise location of any proposed roads are subject to the detailed site assessment carried out during the subdivision application process. In areas not covered by a Development Control Plan the layout and width will be determined by Council on their merits.

Kerb return and cul-de-sac details are contained within Section 2-12 of this guide.

3.4 Half Width Roads

Council does not encourage the construction of half width roads, however in certain circumstances this may be permitted. A minimum 4.5m width pavement must be fully constructed.

Where half widths roads are approved, the applicant is required to provide sufficient details regarding the extent of works to ensure operational effectiveness and safety. This will involve a full design together with sufficient details to ensure adequate transitions to the standard road pavements inclusive of full width cross sections.

3.5 Construction Specification

Council's Works Specification - Civil complements this Guide and shall be referred to for all construction details.

3.6 Pavement Design

A formal pavement design shall be prepared by a registered N.A.T.A.

laboratory based on sampling and testing of the subgrade materials from the site. Details of the pavement design, results of subgrade testing (including 4 day soaked CBR's) are to be submitted to Council for approval prior to commencement of pavement construction. The design shall be based on Traffic Loading Criteria specified in the Consent for the proposed works, which is based on the Design Traffic Loadings shown in Table 3.2.

The structural design of the pavement must be in accordance with the following procedures and shall have a con
