Forward Works Design - Gnowangerup Recreation Precinct

⁠⁠⁠The Shire of Gnowangerup is constructing a recreation precinct, adjacent to an existing park, within the town of Gnowangerup. The Gnowangerup Recreation Precinct consists of a skate park, pump track, and multi-use hard surface court amongst a landscaped area. To enable efficient delivery the Shire is seeking the design of preparation works prior to the main Precinct design and construction.

The Forward Works consists of three elements:

i. Existing Water Corporation infrastructure is to be realigned to avoid proposed structures;

ii. Site and Preparation Works; and

iii. Works to road reserves.

Scope:

A design to realign Water Corporation infrastructure (water pipeline) located in the vicinity of Aylmore Street between Yougenup Road and McDonald Street in Gnowangerup. The existing water main is located within the Aylmore Street road reserve, though investigations have indicated that it is likely to differ from the plotted location on Before You Dig plans. Indicative sketches of the location are provided in the Concept Design by Convic.

The proposed water main is to follow the pathway within the Recreation Precinct (NW-SE orientation). Connections are to be made to the existing water main located in the Yougenup Road reserve (north-south) and the existing water main in Aylmore Street). 

Allowance is to be made for undertaking the works with minimal disruption to the provision of Water Corporations services to the town. Consideration is to be given to ensuring that water supply is maintained to the four dwellings adjoining the southern laneway that is accessed from Aylmore Street. Works to existing and retained Water Corp infrastructure (capping, valves etc.) is to be detailed.

Precinct Site Preparation Works

The site is to be prepared to enable the construction of the Recreation Precinct features as detailed in the Final Concept Report.

The scope of works incorporates:

Demolition

• Remove kerbing

• 15m either side of Aylmore St on Yougenup Road

• Along both sides of Aylmore St to Laneway (eastern side)

• Remove trees and vegetation on northern side of Nobarach Park

• Remove any miscellaneous items from project area (Blue)

• Remove northern footpath at Nobarach Park

• Remove bitumen, concrete on Lot 40 Yougenup Road and Aylmore Street within project area

Earthworks

• Cut and fill ground levels to -0.05m level below indicated FGL (refer to levels in Concept Design Package)

• Ensure that site is stabilised from wind and erosion until works can commence.

Drainage

• Allow for one connection within Precinct into stormwater drainage system along Yougenup Road. End of pipe connection to be located at western side of Precinct (to the south of the Skate Park, outside of footprint) and capped (allow for future connection to Skate Park drainage).

• Allow for one connection within Precinct into stormwater drainage system along Aylmore Street. End of pipe connection to be located at eastern side of Precinct and capped.

Footpath

• Kerb (match adjacent existing kerb profile and materials) to extend from northern end of Yougenup Road to southern end.

• Allow for pedestrian ramp at pathway in Nobarach Park

• Allow for pedestrian ramp on western side of Yougenup Road

• Kerb (same profile) to extend the eastern side of the precinct from Lot 40 Yougenup Road to southern end of precinct

• Allow for 3m wide flush entrance to precinct from Aylmore Street within kerb at Precinct footpath.

• Paved footpath along extent of Yougenup Road from the northern lot boundary of Lot 40 Yougenup Road to the Primary School road crossing. Paving width is to be from road kerb to edge of precinct (paving to match existing on northern end of footpath).

• Provide concrete edge to stabilise paving

Road Infrastructure Works

Yougenup Road and Aylmore Street are to be subject to works to allow the formation of the Recreation Precinct. A portion of Aylmore Street is to be closed and removed (refer to Final Concept Report), with a kerb and parking to be provided to the eastern side. Yougenup Road is to have the turning lane removed, island altered, and a kerb and footpath provided along the extent of the Precinct with associated parking bays.

The scope of works incorporates:

• Extend southern island along Yougenup Road from start of turning lane to Aylmore St intersection.

• Allow for pedestrian crossing from pathway in Nobarach Park

• Remove bitumen at marked onstreet parking along Yougenup Road and install maroon coloured bitumen

• Allow for foundation preparation works

• Remove line marking and bitumen to eastern turning lane on Yougenup Road (to Aylmore St)

• Install compacted gravel to Aylmore Street (temporary road surface until Precinct works are complete and then will be bitumised).

• Mark Yougenup Road parking bays as per parking sketch

• Allow for sufficient drainage points along Yougenup Road and Aylmore Street and connection into existing stormwater drainage system.

The Shire is requesting quotes to prepare the design package for one, some, or all of the Forward Work elements of the Gnowangerup Recreation Precinct. This RFQ outlines the scope of services to be provided, objectives and standards, conditions of a submission, and relevant information.
