Deliver quality outcomes

Beejays Solution Flooring & Interiors has worked as a contractor on projects managed by ISL Consulting over many years, including projects for the Ministry of Education, NZ police and the wider commercial sector. ISL’s projects have always been well planned, well organised and clearly structured, with strong communication and practical coordination throughout. Their approach helps contractors understand expectations, maintain momentum and deliver quality outcomes. We have valued working with ISL and would be happy to recommend their project management services.

Strong coordination and practical project leadership

Strata Architects has worked with ISL Consulting on multiple projects, with ISL providing project management services across a broad range of work, from large weathertightness remediation projects through to smaller specialist projects, including AVL installations for NZ Police. ISL has consistently delivered clear communication, strong coordination and practical project leadership. Their professional, reliable and solutions-focused approach has added real value, and we would be pleased to recommend their project management services.

Professional, practical and outcome-focused

I have worked with ISL Consulting for many years and have consistently found their work to be professional, practical and outcome-focused. Their deliverables are always clear, well considered and completed to a high standard, with an excellent understanding of both the technical and the broader project requirements ISL bring a calm, experienced and solutions-focused approach, and their input has added real value across a range of property and asset management projects. I have no hesitation in recommending ISL to others.
