GREEN & BLUE INFRASTRUCTURE developed to BS3882:2015 for use in the urban environment . Having a naturally open structure , Greentree Amenity Tree Soil allows for
compaction without sacrificing any water percolation or aeration properties of the soil .
To complete the tree pits , MacGregor Smith specified the Fortress tree grille tray . This is designed to accept block paving to ensure a seamless transition to the surrounding paved finish . Each pit included an irrigation pipe topped with Greentech ’ s Mono Relief Piazza aluminium filler cap , which was set flush into the paving .
To ensure that the tree ferns in the sunken garden received adequate irrigation , the decision was made to fit a fully automated Rain Bird irrigation system , also from Green-tech . The system was custom designed for the area and featured micro-sprays and driplines , along with the all-important pressure regulators and solenoids . The pressure regulators are critical to any automated system , as they ensure that each emitter or drip line provides the same amount of water no matter how far down the line from the water source they are .

Jamie Cusack , Senior Associate from MacGregor Smith comments , “ This was a challenging project , not only with the sunken garden , but also the tight spaces in which to work and get deliveries in . On this project Green-tech were particularly helpful in respect of providing detailed design input into the automated Rain Bird irrigation system , which helped ensure the successful establishment and longevity of the distinctive tree ferns .
Alasdair Innes , Green-tech Specification Advisor adds , “ It ’ s always a pleasure to work on any MacGregor Smith project , and we first visited the site in February 2022 as the exterior trees were going in but before the sunken garden was in place . It was great to go back and see that everything has come together , especially the automated irrigation in the sunken garden .
