Health NZ - Te Nikau, Grey Base Hospital, Top Carpark Drainage and Resurfacing

Please provide plans showing parking, land contours, drainage and a fixed price quote for the upgrade of the top carpark at Te Nikau Hospital. See attached concept Plan (rough drawing showing area in pink attached). Approx. 4350m2
The two main purposes of this upgrade are Safety of our users and maximisation of the land available for parking.
We would like to use a minimum of 30mm asphalt as the finish coating over a new AP 40 base.
It will require recontouring of the ground and include new drains and sumps with connection to the waste water system.
The design should be based on a traffic safety plan based on safe movement across the site by users. This will include speed limits and crossing points and pedestrian flow (including wheel chairs).
All existing service hatches/ lids will need to be raised (lowered) to fit the new contour.
Design and supply new curb and channel as required and specified in your quote. This will include nib walls and V channels. We require no standing water and all areas to have a drain path for rain water.
Provide a parking layout and once approved paint the areas as required for parking/no parking, give way etc.
Basic layout to be similar to the existing.
Care must be taken as we have limited plans showing the old infrastructure in the ground. Currently
Boiler pipes, Town water, Sewage, Fire sprinkler pipes, Fibre cable. Copper cables, Power and Streetlights to name a few. You will need to locate these services and supply an updated plan of those found during these works at completion.
All removed surfaces including gravel waste must be disposed of as per District Plan. On site dust to be kept to a minimum at all times.
