PSC requests quotations from suitably qualified and experienced organisations offering to provide Topographical Survey Services for the development of the RWRM associated with the Parkes RWS Project - Phase 2.

As a minimum, the following scope of services shall be undertaken for the provision of Topographical Survey Services for the development of RWRM design development:
1. Site inspection(s) and review all background documents.
2. Complete the following fieldwork:

RWRM Pipeline;
I
Obtain all relevant utility service information available from service authorities through Dial Before you Dig and Parkes Shire Council.

Obtain all relevant survey control information from LPI.

Undertake site reconnaissance and briefing with the Project Manager and Parkes Shire Council.

Undertake site risk assessment in accordance with WHS Regulations and operate a safe system of work whilst on site, including adherence to an approved Project Safety Plan.

All applicants are to provide evidence of currency of relevant insurances, and evidence of an accredited WHS system.

Adopt in MGA (strict) and AHD, permanent survey control marks along the length of the proposed pipeline routes established in the LPI SCIMS database.

Using RWRM concept design as a guide, peg out pipeline route(s) with numbered angle pegs and line pegs placed at not more than 200m intervals (preferably inter visible) and place two recovery tie marks at each angle peg. Recovery ties to be shown on the plans. All pipeline routes shown as solid lines on figure 1 are to be surveyed.

Investigate and peg a detailed pipeline route in consultation with Parkes Shire Council, considering such factors as constructability, existing or proposed utility services such as Telstra etc, minimal disturbance of vegetation, remediation of existing roads and other infrastructure.

Locate services using pipe and cable location device and / or visual evidence and / or DialB4UDig Plans. Obtain depths, directions and diameters where possible by a survey crew, otherwise these will be estimated from plans provided and noted accordingly.

No allowance for the potholing or exposure by mechanical means needs to be included at this stage. If required, Council will engage a professional services locating contractor shall more detailed investigation of services be required.

Once the pipeline route has been pegged and investigated, Council will inspect the route and either approve the route for final survey or make amendments. Once approved, conduct a route plan and longitudinal survey along the intended pipeline route. Data points along the long section shall be spaced not more than 30m apart and at changes in grade of the natural or formed surface. Crossing of services by the intended pipeline route shall also be surveyed and plotted on the long section plan with the nature of the service, depths and diameters shown.

Locate features approximately 5m either side of the proposed pipeline route, or further is considered relevant to design and construction, including trees, boreholes, kerb & gutter, roads/tracks, fencing, services, creek crossings. Sufficient detail shall be located and shown on the route plan and long section to enable engineering design, set out, and construction.

Survey is also to include location of sufficient cadastral survey marks, including boundary pegs & reference marks, to be able to plot on the route plan, with reasonable accuracy, the cadastre adjacent to the pipeline corridor, particularly where the proposed pipeline route is expected to cross or be close to cadastral boundaries. This requirement is to ensure that all land matters associated with the pipeline, such as easements and acquisitions, can be quantified and made known to Council prior to the pipeline construction.

Applicants shall make particular note if they are able to add any specific value to the deliverables that may enhance the efficiency of the engineering pipeline design.

Tenders shall demonstrate their recent experience and capability in undertaking pipeline survey projects.

Reservoir and Booster Pump Station;
Detail & contour survey of the proposed new reservoir and booster pump station sites as shown in the concept design Option 11.

Establish a total of three (2) permanent survey marks for both reservoir and booster pump station combined, in MGA & AHD, adjacent to the site suitable for construction set-out and show the location and coordinates of these marks on the plan.

Topographic survey of the sites is to be carried out on a plane grid adopting an MGA origin and azimuth.

Obtain a current Dial Before You Dig search to identify any services in the vicinity of both sites.

Undertake topographic survey of the natural surface to adequately describe the site in an accurate 3D surface model (minimum 20 metre data point grid).

Locate all site features including fencing, tracks, roads, boreholes, visible services, trees, and any other features relevant to engineering design.

Adequately survey mounds, swales, hollows etc to satisfactorily develop an accurate 3D surface model of each site. Show adequate spot levels over the site.

Boundary marks and monuments easily identified are to be located to enable a boundary overlay of the detail and contour survey to a nominal accuracy. A cadastral model fit-for-purpose shall be prepared (not DCDB).

Isolated trees greater than 5m in height or greater than 200mm trunk diameter will be shown individually.

3. Compile the above topographical survey into the following deliverables:
Prepare CAD plan at a nominal 1:500 scale presented on a B1 sheet size.
Show with 0.5 m contour interval.

Include a table of MGA/A
