Good civil contractors never bid ground segment work, because the tender never says "space" and nobody told them the slab under a 13-metre antenna was theirs to pour.

Ground stations, teleports and antenna facilities are procured as facility works and communications infrastructure, CASG-managed or let by a prime, on template formats that punish anything commercial-shaped. The contractors who win aren't better on site, they're the ones whose response maps to the clause structure and whose methodology takes the security constraints seriously.

The opportunity

Two doors into the ground segment

Australia's satellite communications and ground infrastructure work reaches contractors through two doors. Direct Commonwealth tenders on AusTender, CASG-managed for Defence sites and issued on ASDEFCON template formats, or agency-run for civil ground stations such as the Alice Springs facility Geoscience Australia is scoping to relocate. And subcontract packages let by the primes on Defence programs, who run their own supply chains and carry Australian Industry Capability obligations they must evidence with named Australian firms.

Neither door works like commercial construction. The RFT scores how you'll build inside a secure establishment, staged access, escorting, a vetted workforce, live operations continuing around your site, and it does so on a clause structure that expects your response in its shape, not yours. DISP obligations sit underneath most of it. A contractor with an excellent commercial track record and no answer to any of that is not a contender, they're a compliance risk the evaluation is designed to screen out.

What we deliver

What a ground station bid has to survive

Antenna foundation & structural response

Foundation design response for dish structures where pointing accuracy is a contract requirement, differential settlement tolerances, and the survey and monitoring regime that evidences them. This is the section where a general civil methodology stops being credible.

Live service continuity & cutover

The site is already carrying traffic. Staged outages, cutover windows agreed with the operator, fallback positions, and what happens when a window is missed. Evaluators score this harder than the build itself.

RF environment & exclusion zone management

Working alongside live transmitters, RF safety, crane and plant restrictions near an operating antenna, and the exclusion zones that reshape your program. Ignore it in the methodology and it surfaces during evaluation.

Power, earthing & lightning protection

Redundant supply, UPS and generator arrangements, earthing systems and lightning protection for a high-value remote asset, with test and witness points written into the program rather than left for commissioning.

Remote site logistics & workforce

Exmouth, Alice Springs, Woomera. Supply lines measured in days, accommodation and rotation planning, plant availability, and a program that survives a wet season. Costed properly, not assumed.

Commissioning & integrator interface

Your handover is not practical completion, it is a working interface with the systems integrator who owns the payload. Defined in the bid, or argued about during commissioning.

The ASDEFCON compliance, DISP readiness, security management and personnel clearance work sits underneath all of this and is common to every Defence package we write. See our Defence construction and maintenance practice for how we handle it.

The VXS evaluation lens

How ground segment tenders are scored, and where bids die

Critical sections in every ground segment tender

Foundation and structural response, stated tolerances and the survey regime that evidences them
Live service continuity plan, outage windows, cutover sequence and fallback
RF safety and exclusion zone management while transmitters remain in service
Power, earthing and lightning protection, with test and witness points in the program
Remote logistics, workforce rotation, plant availability and weather contingency
Interface schedule with the systems integrator and the site operator

Where ground segment bids fail

A foundation methodology that treats a dish pad like a building slab
Assuming the site can be taken out of service, or never asking
No RF safety plan on a site with live transmitters
Remote logistics priced as though the site were metropolitan
Treating commissioning as somebody else's problem
Compliance content lifted from a base construction bid, which the evaluators have already read
