DESIGN is intentional

Q?

Solid hard landscape vs sustainable integrated systems

or more importantly, permeable integrated systems.

 

 

 

 

 

Step 1> THE SITE

  • purpose (the function of the site)
  • understanding of the site
  • the flow (movement on the site)
  • the experience

And OFTEN, the focus should be

“ Great design is simplistic and based on minimalism” to finding added value through intervention, structural design and aesthetics

Step 2>

Making the KNOWN (the site), more visible

the language of design articulated into a meaningful, feasible and livable space

Integrated systems by combining the DESIGN (formal & structural) & LANDSCAPE (informal & organic)

What is the CONTEXT?

Urban, rural, residential and or industrial

HOW? The intention is for rainwater to run across a surface into the gulley, that directs it into pipes, as stormwater drain facilities as we know it.

  • Pollutants contained is conveyed into overloaded drains, streams, rivers leading to floods and evenly putting a huge amount of strain on protecting our freshwater systems.

BENEFITS

  • Its functional and diverting water away from a building as quick asap.
  • It is durable and known for its performance, and specified in terms of load-bearing forces suitable for light & heavy traffic

To understand the concept, we need to look at

SUDS

(sustainable urban drainage systems)

 

A sequence of water management practice and facilities designed to drain surface water in a manner that will provide a more sustainable approach than what has been the conventional practice of routing run-off through pipes/canals to watercourses. Example suds facilitates detention ponds, preventing downstream flooding.

BENEFITS?

  • Reduce carbon tax
  • Increase property value
  • Reduce flooding
  • Reduce pollution
  • Increase urban biodiversity
  • Addressing the heat island effect

There is already policy supporting the requirement to ensure that peak run-off rates and annual volumes of run-off post-development should not be greater than the previous site conditions, effectively requiring SUDS solutions. Depends on the existing subgrade, with careful consideration should be given to Groundwater table level, pollution prevention, discharge consents and proximity to the building

SYSTEM A (Full infiltration)

Suitable for existing subgrade with good permeability with no conventional drainage systems for discharge, eliminating the need for pipes and gulleys. Water filtrate down into the subgrade. Some of the water is temporarily retained in the permeable sub-base.

SYSTEM B (Partial infiltration)

Suitable where the existing subgrade may not be capable of absorbing all the water. Outlet pipes are connected to the permeable sub-base. Water is drained to other drainage devices like ponds, watercourses and sewers. It removes the need for long term storage.

System C (no infiltration) contaminated sites

Suitable for existing subgrade where the permeability is poor and contains pollutants. Complete capturing of the water. An impermeable flexible membrane is placed on top of the permeable sub-base, which forms a storage tank. Water is transmitted through the outlet pipes, to other devices like ponds, watercourses or sewers. The flow of water is restricted and temporarily stored, before discharging.
