Site Architecture Studio has been requested to provide a reference for Cassari Group who recently completed an alterations and additions project for us at Hale School Junior Boarding House – Brine House ($0.5M). This is the second project Site Architecture Studio has had experience working with Cassari Group and they were selected for the performance on this past project, a $1.8M Mixed use development in Floreat.

Staff Cooperation & Systems
The Hale project was managed and administered through the construction phase by Cassari Group in an efficient and professional manner. Lorenzo Cassiani,managed and supervised the project and was always available. He was well supported by experienced office staff, systems and protocols which were appropriate in achieving the high level of management and workmanship we demand. Lorenzo and his team worked well to expedite resolving issues which arose on site and were always easy to deal with. Although the project value was small, they gave it the attention we would expect from Contractors on much larger and more complex projects. Lorenzo was always quick to seek advice on issues encountered and worked cooperatively to resolve issues.

Cassari Group had a very tight program to meet the beginning of school term. Cassari were prompt to mobilise the site and manage the shop drawings and fabrication processes prior to the Christmas shut down period. Typical of that time of year, other construction delays and program issues were experienced; however, Cassari worked diligently to make up lost time and completed the project as per the original program. Lorenzo always under committed on their program but always over delivered.

Cassari approached all Contractual matters diligently and appropriately, providing all necessary supporting information to clearly justify all legitimate claims under the Contract. Their submitted Variations were always fair and reasonable. We found Cassari’s Contractual correspondence thorough yet not excessive which makes our administration job easier.

The project occasionally raised design problems which Cassari worked willingly to resolve on site with the view to providing the best possible solution for the project and client. This diligence and ‘can do’ attitude suggests that Cassari values forging good, continuing relationships with its clients and also their trades – a prerequisite for obtaining consistent, good quality which we consider Cassari to achieve.

The works were occupied during the end of the construction and Cassari worked well with the client to meet their safety and operational needs. Lorenzo liaised direct with the client to ensure they were aware of the construction activity on site at all times so disruption to the school was minimised and well managed.

In short, we would recommend Cassari Group to undertake a range of commercial, institutional, and residential projects. We find them a pleasure to deal with and as a result, where appropriate, will continue to request they tender on our projects.

Cassari Group has worked with our firm on a range of complex Commercial remodelling projects since 2018. These include, installation of subsoil drainage in an existing office complex basement, the construction of a Bridgestone facility, an F45 gym, and a new internal Mall within an existing retail complex. Each of these projects involved complex structural modification works, minimising disruption to existing tenants, exacting specifications and tight programmes.

In each case we were very impressed by the professionalism, construction knowledge and commitment to producing high quality outcomes in terms of cost, build quality, time programme and transparency. Cassari Group director, Lorenzo Cassiani, was outstanding. He was happy to get on the tools, get his hands dirty and stay close to his tradespeople to ensure Cassari group’s promise to us was fulfilled. He also developed a close rapport with existing tenants and ensured that disruption to their operation was minimised and, if unavoidable, occurred at times of least impact.

We value Cassari Group’s high level of transparency, clarity and precision of all contractual claims and advice; with alternative, more economical solutions, often provided to achieve our overarching objectives.

We have no hesitation in recommending Cassari Group for a wide range of construction projects.
