NSW Parliament House – Standby Diesel Generators and Mechanical Switchboard

The works carried out include the design, supply and Install of a 2 x 1650kVA standby diesel generator system, associated building works and the replacement of existing mechanical switchboards. Ryan Wilks was responsible for providing a turnkey solution for this emergency standby system, ensuring seamless integration with the existing onsite services. The detailed scope of works included the following.

Removal of the existing gas fired generator, associated controls and chiller,  main switchboard modification with the integration of new ATS controllers. The new ATS system performs a break in transfer from Mains to Generator supply during a mains outage but allows the two supplies to be synchronised on return to Mains Supply.

Due to limited outside air availability within the basement, Water Cooled Air-Conditioning (WAC) Units have be installed at each end of the new generators to condition the air and maintain a desired room temperature of around 28oC when the generators are operational.

The Cooling system on the two generators servicing the water jacket system and the charge air cooling system is provided using the centralised plant condenser water system with heat exchangers mounted to each set. 

Challenges and major works:

  1. Extensive design and engineering review with the client to ensure Ryan Wilks met the specification brief and stakeholder expectations.
  2. Detailed electrical and mechanical building survey of all existing services to enable the design engineering of the new emergency standby diesel system.
  3. Decommission and staged demolition of the existing gas fired generator.
  4. Staged decommission and demolition of existing mechanical switch boards
  5. Design supply and installation of diesel generators & diesel generator output switchboard.
  6. Associated Electrical Work including Automatic Transfer Switches (ATS) Units, cable trays, lighting, dry fire and security.
  7. Design, supply and installation of mechanical switchboard and mechanical ATS servicing the centralised HVAC plant.
  8. Fire services & Building Management Services (BMS).
  9. Extensive waterproofing works
  10. Lifting works to remove redundant SGP, chiller and installation of new building materials and new SGP through 6 basements levels of gatic access
  11. Supply and installation of combustion exhaust systems connected to existing exhaust risers
  12. Supply and installation condenser water pipework
  13. New fuel filtering and fuel system works connected to the existing bulk tanks.

Jamison High School – Cooler Classrooms Project

Ryan Wilks completed the air conditioning installation on this project at Jamison High School in May 2019 as part of the NSW Governments Cooler Classrooms Program – Thermal Comfort Indoor Air Quality Works

The works involved the installation of new split type air conditioning systems and fresh air fans within a total of 65 classrooms, as well as replacing the existing Library air conditioning unit.

Whilst each project poses its own challenges and obstacles, this project included the additional challenges of working around the day to day operations of the school and the students resulting in much of the works being undertaken out of hours.

The different types of class rooms also posed their own challenges. What worked in general teaching classrooms, didn’t necessarily work in the arts rooms, the lab’s or in the workshop’s areas

We are pleased to say that with support from the Principal and the Department  we were able to develop specific designs for each of these areas.

The original intent for the main classrooms was to install the new air conditioning and ventilation systems within a large bulkhead at the front of each room above the white boards. As part of our design review process we proposed to remove the equipment, and more importantly the noise generated by the equipment, and the large bulky bulkheads from within the classrooms and install the new air conditioning systems within the common corridor area outside the rooms, hidden behind a new and modern suspended tiled system bulkhead.

This solution removed the noise source from the room, removed the ugly bulkhead and made serviceability a lot easier. Most importantly this design provided a better learning environment for the students. We are pleased to say that this solution (initiative) was adopted on other Cooler Classroom projects by the Department.

In other areas the new fresh fans and ductwork have been located within bulkheads constructed in the corridor areas. These bulkheads have been installed to blend in with the existing corridor walls and in many instances the angles of the walls, and ceilings. Existing colour themes have been maintained which has assisted the new works to blend in, it looks like it has always been there.

In the lab areas we had two rooms that were nearly all windows. In these rooms we came up with the unique solution to hide the fans and ductwork in new cupboards. We ordered and installed new cupboards to match the existing ones and then mounted the fans and ductwork within the cupboards.

The most positive comments we can make and have received about our installation works is that you cant see them, you  don’t know that they are there, which is exactly how we planned it.

In the Workshop area, and in the Arts rooms the industrial feel of the areas has been reinforced by the installation of exposed spiral ductwork, and exposed cable tray and lids for cabling and pipework.

A new mechanical control panel has been installed in each classrooms. In keeping with the “blending in” we installed panels in white, grey and light blue powder coat to match the existing walls and panels.

To support the new air conditioning upgrade a total of seven (7) new MCC / MSB panels were installed to replace existing, along with new sub main cabling. The existing Main Switchboard was also extended and a new  60 kw solar installation was installed. This project really emphasised Ryan Wilks ability to carry out all of the trade disciplines we are known to possess.

We’d love to show you pictures of our works, but as we mentioned most of it has been hidden away by new ceiling or bulkheads, but here’s a try;

 

 

Main Switchboard Replacements and Upgrades

Life cycle replacement, meeting the demands of current and future electrical demands are the main factors that drive switchboard replacement and upgrading.

Our highly experienced team can provide a seamless replacement of your Switchboards. We can co-ordinate your change-over from design through Switchboard construction to a successful handover. At all times maintaining our commitment to high quality workmanship and safety.

Power Distribution Systems

Ryan Wilks understand that Electric power – the life-blood of industry – can represent up to 40 per cent of the total cost of production especially in energy -intensive industries. The management and control of electrical power underpins profit and success in businesses that use higher than normal  amounts of electrical power.

Industry now demands flexible, scalable solutions for the reticulation and marshalling of electric power – switchboards and reticulation systems that can be extended, modified and adapted to suit a dynamically varying range of requirements within an operational facility. Power must be quickly reticulated when and where it is needed, responsively and effectively.

Ryan Wilks can design, procure and install an electrical power distribution system to meets most clients needs.
