Mechanical Services

This section covers air conditioning, mechanical ventilation, and aspects of the Building Mechanical System (BMS).

Connection interphase to base building BMS must be discussed with the Building Management Team prior to any HVAC mechanical services works commencing in the fit-out.

During your fit-out, please provide your Project Manager with detailed plans showing the location of all staff, equipment, and lighting so the heat load and the usage of all areas can be determined. The Project Manager will also need to provide these plans to the Building Management Team’s preferred air conditioning consultant.

Ductwork modifications must be minimised to maintain straight duct runs, the use of flexible ducts need to kept to a minimum with bends kept under radius of 1.5 diameters.

Areas which are highly partitioned or have floor to slab partitioning must have sufficient return air grilles to allow return air to traverse the above ceiling space when partitioned doors are shut.

Tenancies on multi-tenanted floors may require either acoustic security transfer ducts across the tenancy dividing partition or return air grilles in the tenancy wall to the core corridor and corridor ceiling grilles; to allow the return air from the tenancy to leave the tenancy and return to the false ceiling level to return to the return air riser.

Air and water balancing of fit-out works must be performed by approved balancing contractors. The final balancing detail must be reviewed by the base building services consultant.

Electrical, Security, Communications Systems

The electrical and security systems provided by Investa are designed to be tenant friendly, enabling efficient general servicing and substantial and regular fit-out alterations, with minimal inconvenience.

Prior to any demolition works, your Project Manager must check existing cables (power, data and communications) in the tenancy and obtain approval from the Building Management Team for any isolation or cutting of these cables.

This is to avoid accidental damage to existing base building cables, and impact to base building equipment operations. If the Building Management Team have not been advised and proper authorisation not provided to the main contractor, it will be the Lessee’s responsibility to restore damaged services.

 

Tenant Lighting

Lights are controlled from group switches.

Tenant Distribution Boards

All electrical circuits and GPOs must be numbered (circuit number and distribution board number) and the distribution board permanently labelled as appropriate. The load across phases must be balanced.

Wiring

All wiring run in ceiling spaces, including the central service corridor, must be supported on trays or catenaries, or clipped to the slab and bundled by means of cable ties.

No wiring whatsoever will be allowed to lie on the ceiling grid or tiles, be clipped to the sprinkler pipe work or run in the data cable trays.

To assist you with the cabling of power and communications cabling from the core area services, cupboards to the tenancy area facilities have been provided and are mentioned below.

Fire Services

The Life Safety Systems associated with the building are designed to a high commercial standard and maintained and tested to ensure compliance with the prevailing Australian standards.

The Premises has a Fire Engineering Consultant that certifies the building annually and on an ongoing basis. All tenant areas that are altered or refurbished will be required to engage the Premises Consultant to review and carry out final sign off for the fire safety measures at the tenant’s expense.

The classification and hazard rating for the building is as follows:

  • Tenanted areas are Ordinary Hazard I;
  • Car Park Ordinary Hazard II; and
  • Retail areas Ordinary Hazard III.

Smoke System

Addressable Smoke detectors interfaced to the base building main fire monitoring system are mounted above each fire exit door and return air riser. These detectors are sensitive to dust and smoke which may be generated as a result of fit-out works. The Project Manager shall notify the Building Management Team in writing when dusty or smoky works may take place so that the detector(s) may be isolated. A Fire Impairment Form must be completed and lodged prior to any isolation taking place.  

Any charges incurred from Fire Brigade attendance for false alarms associated with fit-out works will be charged to the Project Manager. Under no circumstances are smoke detectors to remain isolated overnight after works have been completed.

Hose Reels

The hose reel cupboard adjacent to the fire stair door must remain accessible from the fire stair. All parts of a tenancy must be reachable by a hose reel. The Project Manager will arrange for additional hose reels to be installed to achieve this if required.

Coordination and notification to the Building Management Team is required in the event of Hose reel shut down being required.

Note that access to the aforementioned fire stairs from each level of the tower is not available at any times (unless there is an emergency).

Emergency and Exit Lighting

Emergency and exit lighting is installed on an open plan basis to comply with safety requirements. As a result of the tenancy fit-out, further emergency and exit lighting may be required, and any such additional lighting is at your expense and must comply with safety requirements.

Whilst Management will undertake 6-monthly emergency exit light testing, it is your responsibility to install service and repair exit lighting. Investa can arrange this on your behalf and this sundry charge will appear on your monthly rental invoice.

A certificate of compliance for the tenancy area Emergency and Exit Lighting must be supplied as part of the tenancy Fire and Essential Services documentation.

The following table contains the design parameters of the fire and emergency systems.

 

Emergency Warning and Intercommunications System

The Emergency Warning and Intercommunications System (EWIS) incorporate speakers, which are distributed throughout the building and tenancy areas. Tenancy fit outs generally attenuate the volume of the EWIS speakers, and the Project Manager shall ensure that additional speakers are installed, or speakers are relocated as necessary to achieve authority compliance (AS2220).

While general EWIS speaker wiring can be performed by the tenant’s contractors as part of the fit-out works, any disconnection from or connection to the ‘live’ EWIS must only be performed by the building preferred contractor. The Project Manager will be held responsible for any damage to the EWIS which results from unauthorised disconnection or connection.

Sprinkler System Isolations

  • Drain downs must be kept to an absolute minimum. Any drain downs must receive approval from the Building Management Team with no less than 24 hours' notice
  • Drain downs left overnight or for an extended period are conditional on approval by the building insurers and adherence to any requirements imposed by the insurers. Any costs associated with this approval and subsequent conditions will be the responsibility of your Project Manager.

  • Drain down and refill operations will only be performed by the building preferred contractor, without exceptions.

  • The existing sprinkler system will be retained in service whilst new pipe work is being installed, and all new pipes must be cut over during one drain down. Sprinkler systems must be refilled and operational overnight and on weekends.

Context

Distributed Antenna System (DAS)

Providing a quality mobile phone coverage experience within a building is achieved using a dedicated in-building system known as a Distributed Antenna System (DAS), sometimes referred to as In-Building Coverage (IBC) system. The system is installed throughout the building including cables in risers and ceilings, and antennas below the ceiling within the tenancy, lift lobbies and public areas. The service is delivered via white (unless painted) dome antennas and will be visible when installed below the ceiling. In some instances, the antennas may have been placed above the ceiling, however this is to the detriment of the performance of the system.


Due the topology of these systems any damage to an antenna or cabling within the ceiling may have an impact on a larger portion of the system beyond the immediate impacted area. Damage to the system results in not only a deterioration of mobile performance below the antenna, but over the entire ‘sector’ - often 10+ floors with significant deterioration of performance in lifts. Consequently, the preservation and adjustment of the system to accommodate a specific tenant fit-out is critical. A DAS is highly specialised equipment and should not be handled by a standard electrician or builder.


The most recent version of the Mobile Carrier Forum (MCF) Guidelines published in November 2018 represents the latest set of operator guidelines outlining details of performance requirements, testing requirements, installation standards and PIM expectations as a point of reference for DAS works.

Tenant Activity Impact

There are primarily three (3) ways in which the DAS performance can be negatively impacted as a result of a tenant activity.
  • Modification of floor fit-out

    Changes to the fit-out may limit the quality of coverage throughout the floor, particularly if new walls are being erected for offices and meeting rooms. For example, antennas being isolated in enclosed area may significantly impact the performance of the DAS throughout the floor.

  • Relocation/Damage to Infrastructure

    Undertaking any tenant fit-out or refurbishment resulting in antennas being placed above the ceiling, removed, or damaged will lead to coverage gaps and deterioration of the ‘sector’ of the DAS within the building. Similarly, it is not uncommon for coaxial cable to be cut or bent beyond the prescribed bend radius which can result in cables having to be replaced in their entirety to achieve the required DAS performance levels.

  • Passive Intermodulation (PIM) Interference

    A more subtle activity may result in the creation of interference on the system whereby the materials of nearby items including fit out materials and furniture (particularly metal) can negatively impact the performance of the system. Typical issues come in the form of emergency lights, sprinklers, metal lockers, etc. This is generally not malicious damage, but it will result in a deterioration of performance. Typically, any DAS works on a given floor should be at the back of a fit-out process to allow for PIM optimisation once all the new structures are in place.

Process to Limit Impact

As with all utilities the preservation of the DAS is paramount. All costs associated with retaining the DAS in its’ operational state during and immediately after the fitout will be borne by the fitout contractor and their respective client.

DAS system with a lead operator. Tenant Fitout

Refer to the specific license between the landlord and the operator for specific process and notification periods. However typically the process will progress as follows.

1. Provide notice to the operator of the upcoming changes to the floor including relevant information - typically RCPs and partition plans will provide the operator with the information required to move forward.

2. The lead operator may choose to pursue works themselves and will likely provide a quotation, or they may be willing to refer the work to a qualified party depending on the scope and the operator’s policies

3. As the system is live it’s likely that works will need to be completed within an ‘outage’ period, usually at night or out of hours, where the operator will power down the system for WH&S reasons.

4. The operator may put in place documentation or testing regimes in line with their requirements.

Please contact the site facilities manager or other landlord representative should you require further information.
