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. |
Access Process
Prior to any telecommunication equipment installation occurring the design will need to be reviewed by our consultants. In the majority of circumstances, the chosen service providers(s) will require access to common areas, including the MDF Room and Communications Risers (other than those on the floor you intend to occupy), to prepare a suitable design for review. The request to access site to prepare the design should also be made to TAS who will co-ordinate access between the chosen service provider and the Facilities Management Team at site.
Access requests can be made to the TAS team via their online portal. The requests are made by the chosen service provider directly to TAS via the TAS portal. The TAS portal is located at the following website address:
https://portal.telcoaccess.com.au
Design Review
Once the design has been prepared it will need to be submitted by the service provider to TAS for review. TAS will provide a response to the service provider, in consultation with the Facilities Management Team. It is most likely that the chosen service provider will be aware of this process. For further information, you or your nominated service provider can contact TAS on the details provided above, noting that all submissions are to be made via the TAS portal.
Distributed Antenna System (DAS) – Mobile Phone Coverage
Please note that this property has a dedicated mobile coverage solution, known as a Distributed Antenna System (DAS). 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.
Context
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. The MCF is updated every few years to reflect the changes in technology and should be reviewed in accordance with these guidelines.
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.
1. 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.
2. 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.
3. 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 any 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 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 is 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 H&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.
