Towers

Communications and lighting towers, fabricated and standing

A tower job needs four trades that don't usually share a ute: fabrication, civil works, rigging and rope access. Industrial Site Services has all four, so the foundation, the lift and the fabrication are one company's job and one phone number. You get a tower handed over standing.

We build communications, broadcast and lighting towers. Wind turbine towers are on the Renewables page.

What we do with towers

• Fabricate: in the Te Rapa workshop, to your engineer's spec or to a design we make repeatable. The NZ Police coastal tower was built with every attachment point fitted in-house before it left; Lightwire's 42 towers came off one design so parts could be made in bulk.
• Foundations and civil: for each Lightwire site, a 4 m × 4 m × 900 mm hole, a 440 kg reo cage, boxing and about 25 tonnes of concrete, then grouting, earth pins and conduit.
• Install: each 800 kg, 10 m tower goes up in four pieces. Where the road runs out, materials go in by helicopter.
• Rebuild live towers: Ruru, a working radio tower for the central North Island, rebuilt at about 450 m above sea level in RF suits with monitors.
• Replace lighting towers: Seddon Park's 50 m towers derigged and replaced; four new towers at FMG Stadium for the Women's FIFA World Cup broadcast standard.
• Maintain: the NZ Police tower is on ongoing maintenance with us. Repairs at height are done by rope access where a scaffold would cost more than the job.
• Remove the old one: the previous NZ Police tower came down once the new one was live.

How a tower job runs

1. Send us the spec, or the site. A drawing from your engineer, or a brief and a location, and we'll tell you what's possible and what it will take to get there.
2. We plan the ground and the delivery. Foundations, access, landowner arrangements and whether the last leg is by truck or helicopter. All of it under our ISO 45001:2018 health and safety system; certificates are on the Health & Safety page.
3. We build, lift and hand over. Sections fabricated in Te Rapa, installed on site, fittings and conduit in, old tower removed if there is one, and maintenance afterwards if you want it.

What we don't do

We fabricate, install and maintain towers; we aren't a structural engineering consultancy. A tower that needs a producer statement gets its design from your engineer, or from a consultancy we work alongside, as we did with Holmes Consulting on the FMG Stadium roof. Wind turbine towers belong with our Renewables crews.
