Data & Security Estimating Services in New Zealand

Telecommunications cabling in New Zealand must be installed by a registered cabler under the Telecommunications Cabling Regulations, and premises cabling usually follows AS/CA S009. Fibre lead-in to the building is generally arranged with the network provider and may need ducting and a termination point allowed for.

Access control on escape doors must work with the fire alarm so that doors release in an emergency, as required by the Building Code clause C provisions for means of escape. This interface needs coordination between the security and fire contractors and is easy to leave out.

We measure and price to the drawings. Design compliance and building consent remain with your designer and building consent authority.

Where do data & security estimates go wrong?

Future capacity is another common gap. Comms cabinets are often sized for today's outlet count with no space for growth, and adding capacity later is far more expensive than allowing for it during construction. We note spare rack space, spare cores in backbone cabling and spare containment capacity as options, so the client can decide whether to include them now while ceilings are open and access is easy.

Low-voltage scope is often split between the electrician and specialist contractors, and items fall between them. Containment, power to devices and fire alarm interfaces are common gaps.

Testing, certification and commissioning are another gap. Data cabling needs testing to its category, and security systems need programming and handover.

Finally, head-end equipment such as recorders, switches and controllers is sometimes assumed to be supplied by the client. We list it so the scope is clear.
