Quality & Workmanship

More than 60 years ago, our founder, Jan van der Sluys (senior), realised that quality workmanship would increasingly become the only differentiator between construction companies. It is this early realisation that has driven our desire to be recognised for the quality of our workmanship, the materials we use and above all, our people. We undertake to not only meet your expectations, but to exceed them. We are committed to achieve these high standards and all employees at all levels endeavour to commit to, and take responsibility for, achieving this goal.


The expression "Teamwork Builds Quality" was coined in 1991 and signalled a new phase in the company’s development. Isipani, as a collective, actively subscribe to participative management, personified by the Isipani concept. We see everybody involved in the construction process as part of the team: Client, Architect, Engineer, Contractor, Sub - Contractor, Supplier, Financial Institutions and Local Authorities. Every one of us fulfills a certain role and has certain responsibilities. Together we can create something significant.


To enhance teamwork, and to encourage employees to communicate and share their ideas and concerns to management, a workers forum within our company, called the ITISA Committee was formed. This ITISA Committee, is actively involved in the administration and welfare of our employees. Representing employees on various matters and assisting with challenges. The committee manages its own ITISA Fund.

Profit Sharing

Since 1995 an employee profit sharing scheme has been implemented whereby the annual profit, as declared by the directors, is shared with all permanent employees. We think this is unique in a private company. The rewards have been manifold: a loyal workforce, improved communication channels and an increase in quality and productivity in every aspect of our business.

Professionalism & Performance

No compromises. No shortcuts. Just hard work and high standards. We’re proud of our reputation for efficiency and we believe it’s the direct result of our hands on approach and careful integration of all our service components. Constant self-evaluation and appraisal of our services help us reaffirm and refine our core business. As the industry evolves, so do we. As technology changes, so do we. With one area of predictability: our unwavering commitment to quality and our desire to remain at the forefront of construction in South Africa.

Our service integration is facilitated by housing most construction trades under one roof, ensuring quality and helping to avoid delays. We have formed clearly defined and in most cases, long-standing working relationships with sub-contractors which help offset the shortage in schooled labour during peak construction periods. The appointment of the right service providers are crucial to the ongoing synchronisation of project design, site management, construction, quality control and project management. We contract the best, on your behalf.

Most of our work comes through negotiations from previously satisfied clients or through invited tenders. Each project is allocated an experienced quantity surveyor, contract manager and site managers. Team members are required to maintain good channels of communication and individual duties are carefully defined for maximum efficiency.

Thanks to our dedicated team we are able to manage the entire construction process from concept to completion – Effectively, Efficiently and on Time.

After sales service

There is no better advertisement than a satisfied client. With this in mind, we have developed expert in-house teams that is acknowledged by clients and opposition alike as a standard-bearer for after sales service and advice. Team members are on hand to attend to any unforeseen construction problem at short notice, around the clock.
