Design notes

Introduction:

This Design Note, provides guidelines and requirements in relation to Design & Construction of Infrastructure to be handed over to Moyne Shire Council through the various Acts & Permits

1.    Drainage Pits

The use of step irons in pits is not accepted in The Shire, all pits are to be manufactured in accordance with this. Pits with step irons cut off will not be accepted

Drainage pits are not to have sumps and are to be grout filled sloping to the invert level of the outlet pipe, designers are to include a note on plans to this effect.

Contractors are reminded that when specified on the plans for a Double Side Entry Pit, only DSEP will be accepted. Single Side Entry Pits joined together will not be accepted.

FRP Pits are to be used refer to Design Note: Pit Lids

The use of grates on pits is discouraged other than in exceptional circumstances. Their use is to be approved, in writing, prior to the submission of drawings

The use of grates on pits is discouraged other than in exceptional circumstances. Their use is to be approved, in writing, prior to the submission of drawings

2.    Approval Process

All submissions of engineering plans in the first instance are to go to Moyne@Moyne.vic.gov.au the plans are to be accompanied by all calculations and the relevant IDM Checklists. Consultants are to include the applicable Planning Permit number and Certification number in the subject line

Consultants should note that the statutory timeframe for the checking of drawings will not start until all of the following have been complied with and/or submitted:

• Planning Permit issued
• Completed relevant IDM Checklist(s)
• Pavement Design & Geotechnical Report
• Stormwater Management Plan
• Functional Layout Plan
• Safety Audits for Roads and Major Drainage infrastructure

3.    Changes to Approved Drawings

Consultants should note that any changes to approved drawings are to be properly documented.  Each page of the construction drawings that is effected by the proposed change is to be updated and clouded a full set is to be resubmitted for review/approval.

4.     As-Constructed Drawings – IDM Section 7.5 & 7.6

The IDM requires that As Constructed drawings be submitted to Moyne Shire as part of the Acceptance of Works (Statement of Compliance) process. As constructed drawings are to be provided to Council in AutoCAD .dwg format and .pdf. The plans are to be MGA 2020 and digitally scalable

5.     Certification of Plan of Subdivision Prior to Approval of Detailed Design plans.

Section 17 of the Subdivision Act. States that “Works must not start until the Plan of Subdivision has been certified”

Therefore, if Engineering Plans are approved without a certified plan of Subdivision,

• Works must not start without a certified Plan of Subdivision AND
• The submitted Plan of Subdivision must match the approved plans OR
• The engineering drawings shall be resubmitted to match the Plan of Subdivision

6.     Issue Statement of Compliance / Start of Defects Liability Period – IDM Sec 7.5-7.7

Consultants should note that a Statement of Compliance (SOC) can only be issued after all the relevant referral authorities have each given their releases.  Council’s Engineering Department, acting as an internal referral, requires, as a minimum, for the Engineering SOC release, all of the following

a)     That the inspector agrees that the works are to Council standard and has been provided with copies of test results as requested.

b)     All test/inspection records are available eg -

     i)               CCTV of all drainage pipes and pits in accordance with WSA code (Provided prior to PC, Road Crossings to be reviewed prior to wearing course

     ii)              Pavement Compaction (Provided prior to advancement of each layer & prior to proof role)

     iii)             Fill/backfill compaction tests

     iv)             Filter media test results (where Bio-retention elements have been approved)

c)     That any outstanding issues be documented

d)     That any bonds are paid/arranged

e)     That the calculations for the subdivision fees and bonds have been submitted for checking, agreed and the fees been paid

f)      That as-constructed drawings have been provided

7.     Assessment and delivery of Cheques and Bonds

Prior to lodgement of any fees and/or bonds, the consultant must provide a copy of the Schedule of Rates for the works which is to come in a pdf and excel format printable in A4.

Consultants / developers shall note that all cheques for the payment of fees and bonds and documents following approval related to the provision of bank guarantees must be sent/delivered to the Planning Department with all bank guarantees being unconditional (no end date)

All cheques and documents must be attached to a letter clearly referencing the basis for the payment/bond/guarantee.  As a minimum, the information will include–

a)    The name of the development (if applicable)

b)    The address of the development

c)     The planning permit number

d)    The stage number of the development (if applicable)

e)    Any relevant Council reference number

The naming of a new road (or previously unnamed road reserve) is required to follow the road naming process outlined by Geographic Names Victoria (GNV).

GNV maintains a series of rules for ensuring that a street name is appropriate, shares local significance and does not create confusion. The full Naming Rules can be found at here.

In addition to this process, Council maintains a limited number of pre-approved road names for each region in the municipality. Further detail on Council’s Road Feature and Locality Naming Policy can be found here.

For further information or to access the Council pre-approved name list please email moyne@moyne.vic.gov.au marked Attention: Assets Department.

Introduction:

This Design Note, provides guidelines and requirements for the use of pit lids throughout Moyne Shire Council.

Definitions

Activity Centre - Vibrant hubs where people shop, work, meet, relax and often live. Usually well-served by public transport, they range in size and intensity of use from local neighbourhood strip shopping centres to universities and major regional shopping malls.

Neighbourhood Centre - Centres which have a limited mix of uses meeting local needs and are dominated by small businesses and shops and some community services. They offer local convenience services and limited public transport provision but are not necessarily well located on the transport network.

Residential Zone – An area which provides for the housing and accommodation needs of the local population.  For the purposes of this design note a single shop within a predominantly residential area will be classified as residential, but any pits adjoining a delivery access area for the shop shall require a pit cover equivalent to a Neighbourhood Centre.

Industrial Zone - An area which provides for manufacturing industry, the storage and distribution of goods and associated uses in a manner that does not affect the safety and amenity of local communities.

FRP – Fibre Reinforced Plastic.  A lightweight composite material which can be used as an alternative to conventional building materials.

IDM – Infrastructure Design Manual adopted by The City guiding the construction standards of infrastructure

Australian Standard Design Criteria

All pit lids are required to comply with the Australian Standard 3996 Access covers and grates for loading, durability in service and markings.

Location vs. Pit Class

The following table provides a quick guide for the selection of appropriate class of pit lid for various locations throughout The City. The IDM & AS 3996 has been considered in producing this table.

In new subdivisions due to construction vehicles associated with residential housing mounting kerbs whilst accessing individual blocks during the build out phase, a minimum C class pit lid has been specified for all installations, within road reserve. When construction has ceased, and the lid reaches end of life The Shire will replace the lid in accordance with “Existing Area section of the table”

Where the situation is not covered by the below table or is atypical, it remains the judgement of the assessing Council Officer.

Pit Lid Type

FRP pit lids are a lightweight alternative to traditional concrete and steel side entry and junction pit lids. They provide significant benefits to the health and safety of maintenance crews through reduced lifting weight and need for special equipment.

The use light weight lockable FRP lids are mandated throughout The Shire and must be installed in all applications except; where the required class is not commercially available. The colour of the lid is to compliment the soundings e.g. (green in grass). Designers are to specify on the pit schedule the type, class and colour of pits for acceptance.

In limited scenarios such as areas of significance The Shire may require the use of Bluestone style pit lids. Any use of bluestone lids must come with written approval from the Shire’s Engineering Department.

Supplier product images

Moyne Shire expects any design to have undergone a thorough design review by the designer prior to submission to Council for endorsement. Attention is drawn to the various IDM checklists – refer Appendices C, D and E.

Moyne Shire provides a sample of ITPs for contractor’s use where Council inspection is required. Refer below attachment.

These ITP’s while not an exhaustive list, provide detail on Council’s expectations with regard to the construction of assets in road reserves regardless of ownership or gifted to Council as part of a development.

Council expects that the contractor/developer have access to these ITP’s on site and that they are presented to Council for signing upon inspection.

Moyne Shire Standard Drawings have been in circulation since 2007. Since the adoption of the Infrastructure Design Manual many of these are now superseded. A full list of the Moyne Shire Standard Drawings can be found at Appendix A below along with their current status. Refer below attachment.
