1 York Street, Sydney NSW – Services Upgrade for
151 Property

Mechanical, Electrical and Fire Services Upgrade

Service: Design & Project Management

Project Overview

When 151 Property purchased the iconic building at 1 York Street Sydney, they asked Nutbrook Group to conduct a complete technical review of the site’s fixed plant and equipment assets and services.

The site was constructed in the 1970s and comprises 22 storeys of office space, a lobby area with retail amenities, and four levels of basement carparking.

Our review identified opportunities to improve the performance, reliability, safety, and sustainability of the services within the building.

Our Approach

Our team recommended upgrades to the building’s mechanical, electrical and fire services, including:

• A major overhaul of the air delivery system, including new variable air volume units on each floor, that will result in improved control and user comfort.
• End of life replacement of major mechanical equipment including the boilers and chiller with new state of the art, energy efficient equipment.
• Refurbishment of the building fire services including replacement of all sprinkler pipework throughout the building.
• Replacement of the main mechanical services switchboard.
• Upgrade of the existing pneumatic controls to a new site wide, Building Management Control System with direct digital controls.

Based on our review, we were engaged to provide the project management and design services to complete these works.

The Benefits

The upgrades will protect against any potential end-of-life failures or compliance issues that could frustrate tenants while increasing the building’s energy efficiency and saving associated running costs.

Having Nutbrook Group undertake both design and project management proved particularly valuable as it facilitated close collaboration between the teams to develop a project staging plan and minimise disruption to occupants, especially as the works were undertaken within a fully occupied building with high-profile tenants.

The project has seen a positive impact on the building’s energy efficiency and sustainability. Its 4-star NABERS rating moved to 4.5 stars.

In addition to improving the efficiency of the site, the project has removed the issues that tenants of older sites may face as building services run their natural life cycle – a positive outcomes for both the tenants and the building owners.
