About Black Opal Services

An established ACT construction and demolition company, built on more than 40 years of industry experience.

Our story

Black Opal Services Pty Ltd was founded in 2002 by Director Marjan Zagar, who has been working in Canberra's building and construction industry since 1985. Over that time the company has built a reputation for versatility, practical problem-solving and delivering projects efficiently and safely.

We specialise in commercial demolition, building alterations and associated construction works. As licensed builders we can take a project from strip-out through to the finished building work, and we have the resources to deliver projects valued up to $2 million, with capacity for around $200,000 of work each month.

We understand the pressures of commercial construction: safety, programme, cost and quality. We work closely with builders, project managers and subcontractors, keep communication clear and solve problems on site.

Start right, finish right.

Every job starts with a proper plan, the right paperwork and a clear scope, and finishes with a clean site and a proper handover.

Play the long game.

We would rather keep a client for twenty years than win one job. Honest pricing, straight answers and doing what we said we would.

Improvise, adapt, overcome.

Sites change. Latent conditions, programme shifts and scope gaps are part of the job, and we find a way to get it done safely.

Our plant and equipment

How we work with you

Start right, finish right

We identify the project goals with the client and head contractor first, then sequence the work so it is efficient, properly resourced and safe.

  1. Scope and drawings

    Send the scope, drawings and hazardous materials survey. We'll confirm access, hours and services.

  2. Price and programme

    An itemised price and a realistic programme for the works.

  3. Safety documents

    Project-specific SWMS and, where required, a safety management plan.

  4. Daily pre-start

    A pre-start with the project team at the start of every day.

  5. Quality checks

    Inspection and test plans on complex scopes so nothing is missed.

  6. Clean handover

    Waste removed, area cleaned and the scope signed off with you.

Safety and compliance

Safety is our main priority and we meet all regulatory and legislative requirements. Every worker is trained for their tasks and consulted when our SWMS are written, before they start on site. Project-specific documents are updated as the job changes.

  • Company procedures and SWMS for all works
  • Project-specific safety management plans where required
  • Silica controls with HEPA extraction and fit-tested respirators
  • Asbestos register reviewed before any material is disturbed
  • Workers compensation, public liability and plant insurance
