Richmond Valley Council (the Principal) is seeking Tenders from appropriately qualified and experienced Tenderers for the Design and Construction of two landslips on MR145 (Woodburn Coraki Road). The landslips occurred during the 2022 February and March floods. This tender is required to be designed and costed as two separable components of remediation for both sites. A more detailed brief of the extent of services required by Council is set out in Part 3 – the Specification of this Tender document.

The Northern Rivers Local Government Development Design and Construction Manual is a collaboration between Lismore City Council, Ballina Shire Council, Kyogle Shire Council, Richmond Valley Council, Clarence Valley Council and Byron Shire Council.

It serves as a resource that provides uniform development standards across the Northern Rivers area through a comprehensive set of guidelines for design and construction of development infrastructure.

During the February and March 2022 floods, two landslips formed along MR145 (Woodburn Coraki Rd) washing away the embankment involving at the first location approximately a single 30m section and two other sections totalling 47m at the second location. The first site is located approximately 850m from the intersection of River Street and Woodburn Coraki Road and second site is located a further 2.85km along the road.

MR145 is a sealed main road which is a main B double route linking Woodburn, Coraki and Casino. Recent traffic counts in this area predicts the Annual Average Daily Traffic (AADT) is 1819 vehicles per day, with 20.5% of that being heavy vehicles. MR145 services as a primary production and local resident route.

REVISED SCOPE OF WORKS - SITE 2 (Yorks Marine)

TfNSW have assessed this site as ONLY requiring rock protection of the embankment over 2 locations relatively close together.

TfNSW have successfully used this methodology on numerous other areas along the Richmond River between Woodburn and Wardell.

We believe the 2 areas are about 35m and 25m totalling 60m.

Flood Height information is probably irrelevant as the river overtopped the road in this area, therefore the rock protection will be needed for the entire bank face from river floor level to road level.

The top of the rock embankment should be situated about 4m from the existing edge of bitumen.

It is envisaged that this work will not encroach into the existing pavement. These works are to stabilise the embankment for protection of the road.

Your design is to include;

- the slope of the rock embankment.

- the size of the rock required.

- the distance out into the river onto the river floor that the rock will be required.

- The length of the works at each location.

- Guard Rail if required.

Following your inspection of the site, if you think that this approach is incorrect, you can submit an alternate Tender with due justification that may be considered.

The works required will need to be designed and costed as two separable components of remediation at both locations.

Essential Public Asset Restoration (EPAR) claims have been made for the repair of flood damage (that meet the restoration guidelines) to both sites under NSW Disaster Recovery Funding Arrangements (DRFA).
