Engineering and construction firm website cost in Adelaide: local agencies vs Kolonell (2026)

The verdict in three sentences

In Adelaide, a website for an engineering and construction firm built by a local agency costs, as a 2026 ballpark, between 8 000 and 38 000 AUD, about 5 200 to 24 700 USD, often slightly below Sydney or Melbourne prices. Kolonell builds the site of a firm coming out of a merger or a rebrand, with services, references, qualifications and careers, for a fixed price of 2 900 USD, 4 900 USD or 8 900 USD. Kolonell does not shoot photos or video on site and runs no face-to-face workshops: if your partners insist on those sessions, an Adelaide agency is better placed.

What changes when two firms merge their websites?

A merger turns a website project into a brand project. You need to combine two reference portfolios without duplicates, present a larger team, keep the links of both former sites alive through redirects, and reassure existing clients that their contacts stay the same. Public buyers and head contractors also check that qualifications and insurance are held in the name of the new entity.

What do agencies, freelancers and Kolonell charge in Adelaide?

Prudent ranges, drawn from public rate cards of Adelaide agencies, minimum project sizes on Clutch.co, published hourly rates (often 100 to 160 AUD per hour) and freelancer profiles on Upwork. Indicative conversion: 1 AUD is about 0.65 USD.

An Adelaide freelancer can be as affordable as Kolonell; what Kolonell adds is a project manager, native English copy written from your interviews, a written update every week and a fixed price. The team is in Senegal (GMT), nine and a half to ten and a half hours behind Adelaide depending on the season: calls take place late in your afternoon. Payment by bank transfer or Wise, 50 % at kickoff, 50 % at delivery. More in our international offer.

How much does the site cost over three years?

Same maintenance assumption on both sides; Kolonell maintenance after support is quoted on request, so the line is an assumption.

What Adelaide clients expect from an engineering firm

South Australia's economy blends naval defence shipbuilding, health and higher education, renewable energy, copper mining and housing. A building services (MEP) engineering firm works there for hospitals, campuses, public buildings, industrial sites and developers.

• Sensitive sectors: for defence projects, show nothing that is not cleared for publication, and mention Defence Industry Security Program membership only if you hold it.
• Sustainability: cite Green Star projects or NABERS ratings only if your projects are actually certified or rated.
• Titles: Engineers Australia awards Chartered status (CPEng) and maintains the National Engineering Register; check whether any state registration applies to your work and show each title exactly as held.
• References: hospitals and universities often restrict the use of their name; without written consent, describe the project ('HVAC upgrade of a hospital building, Adelaide').
• Certifications: ISO 9001, ISO 14001, ISO 45001 only if the firm holds them.
• Recruitment: the MEP engineer market is tight; a clear careers page about projects, training and flexibility helps convince candidates.

Compliance, facts only. The Privacy Act 1988 and its Australian Privacy Principles generally apply to businesses with annual turnover above 3 million AUD, with exceptions; after a merger, the privacy policy must name the new entity. The Disability Discrimination Act 1992 also covers online services, and WCAG 2.1 AA serves as the technical reference. This is not legal advice.

Red flags in the quotes

• No line about redirects from the former sites: you lose the links and search positions both firms had built.
• References duplicated across the two portfolios, or credited to the wrong entity.
• Hospital or government department logos shown without permission.
• Sustainability certifications or ratings you do not hold.
• A new domain registered in the agency's name.
• Questions to ask: who writes the merged team's biographies? How long does it take to publish a project sheet? Do the former domains stay in our name?

Mini case study

Illustrative example. Marco D. is managing director of a 35-person MEP firm born from the merger of two Adelaide practices. He wants a site under the new brand before bidding on a series of health sector tenders. An Adelaide agency quotes 28 000 AUD, workshops included, about 18 200 USD.

• Agency: 18 200 USD.
• Kolonell Growth: 4 900 USD, plus one day of a local photographer for team portraits at 2 000 AUD, about 1 300 USD: 6 200 USD.
• Difference: 12 000 USD, with a site live in 3 to 4 weeks.

If Marco needs a French version or richer project sheets, Premium at 8 900 USD still sits below the agency quote.
