About YellowX
15+ years in the ground, still family-owned.
YellowX is the excavation & civil venture of BlueXplus Pty Ltd, serving Greater Melbourne & Victoria. We built the business the way we run a site — hands-on, self-performed, and accountable.
Who we are
YellowX is a family-owned Melbourne excavation and civil-works contractor with more than 15 years moving earth across residential, commercial and developer projects in Greater Melbourne and Victoria. Bulk and rock excavation are the core of the business — done with our own crews and 5–35 t GPS-enabled plant — with retention piling and capping, shotcrete walls and foundation bored piers delivered under the same contract, plus drainage, retaining walls and car park works when a package needs them.
Led by director Ehsan Sadreddin, we’re small enough that the people quoting your job are the people running it, and structured enough to carry a head contractor’s compliance, program and expectations. We trade as Bluexplus Pty Ltd T/As YELLOWX (ABN 72 655 259 331).
Where we work
Greater Melbourne and regional Victoria — from tight-access inner-city basements to bulk earthworks in the northern and western growth corridors. Our office is in Bundoora and our plant is sized to travel to where the work is.
Safe and compliant
A genuine WHS system, insured and prequalification-ready. Everyone goes home the same way they arrived.
Straight with numbers
Transparent, itemised BOQs with assumptions called out. No surprises buried in a covering letter.
Fast and reliable
Enquiries acknowledged the same business day, a detailed BOQ typically within 2 business days of full documentation, and a program we can commit to.
