Experts in mobilising newly constructed buildings

Consolidated is an industry leader

Consolidated is considered an industry leader in the mobilisation of cleaning and waste management services within newly constructed buildings and development environments. Our strength in setting up operations on site and establishing methodologies ensure the operations of the building are smooth and seamless.

We work hard to build our service relationships with all key stakeholders in the building and establish a warm rapport to support tenants in the high stress moving in phase. Our wealth of knowledge from working in similar profile properties, enables us to bring with us the expertise gained from over 45 years experience to properties of similar scope, size and prestige.

Our transition plan sets out key milestones and activity required to mobilise the building smoothly and on time. Led by our department heads, the team is fully briefed and trained on all aspects of the services provided. Then the plan is presented to the client during weekly catchup meetings to review progress and gain feedback. Generally this takes place over a 4 week timeframe.
