"This is the first time the Catholic Schools Office (Diocese of Broken Bay) has engaged Marathon to supply and install modular learning spaces and a(COLA). This project was delivered in a very "tight" time frame, from our first site meeting to the delivery of the modular buildings. Marathon exceeded this time frame which required careful and safe site management. The high quality of the buildings also needs to be mentioned as a contributing factor to the project's success. With great pleasure, we recommend Marathon for its design, construction and delivery capabilities of modular buildings."

Sydney Catholic Schools

“Marathon were referred to us by another school. We had a complex site and time constrained brief. Jonathan was accommodating in helping us find a solution that met our needs, both design and time wise and our budget. Marathon were pleasent to deal with in a relaxed and professional way from the time we first met till the end of the project. One of the things we like best about our new modular building is how it integrates with the rest of the school. Jonathan helped us through some design concepts to ensure they delivered a building that met our expectations.”

Illawarra Christian School

“We engaged Marathon to construct and supply a group of buildings to serve the needs of our early Primary Years 1 and 2. The follow-up service for post-construction and maintenance issues following the installation has been fantastic. CAS operational and management staff would not hesitate in recommending Marathon as a service fit for the development of educational facilities.”

Calrossy Anglican School

"Our school chose Marathon as the preferred builder for our projects. They offer a competitive price, good customer service and a quality finish. One point we noted was in our experience in dealing with Marathon, there is always integrity between what the sales manager has stated and the actual final product."

Pacific Valley Christian School

"We wish to express our appreciation for the co-operation of your team during the work and to congratulate you on a job well done. We have enjoyed working with Marathon on this project, and we look forward to working with you again soon."

Bickerton Masters Architecture

"From the outset, dealing with Jonathan and Marathon, in general, has been a pleasure. All aspects of the project have been handled with professionalism and courtesy. Marathon's attention to detail, cooperation with our School Security Unit, their contractor Boston Security and the executive staff at Macarthur Girls High, and your accommodation of the School’s unique security issues have been exemplary and very much appreciated. The School is pleased with the project experience, and the finished product has fulfilled their expectations and, in many ways, exceeded them. I look forward to working with you again in the near future."

School Infrastructure

"Marathon has designed and constructed a modular building for one of the schools in my electorate. It’s a quality building and a positive addition to our environment. If the population begins to fall in 20 years, which can happen, this building can be moved to be used in another growth area. It’s a clever use of the ­education dollar."

Maitland MP

"Marathon caused very little disturbance to the school. They moved quickly and efficiently and always left the site clean and tidy. Communication, cooperation and meeting deadlines were the priority of Marathon throughout the project, and our finished result was outstanding."

Five Islands School

"Marathon was given a very tight time frame to supply a building for our school. Their team worked long days to ensure students could use the facility on the first day of school. Their workmanship is of a very high standard. They are keen to consult and ensure that we are satisfied with the final product. Marathon can provide design ideas if required. I would have no hesitation in recommending Marathon."

St Brigid's Catholic College

"I am pleased to provide this testimonial for Marathon, who recently installed modular classrooms at Canberra Grammar School. The job was not straightforward as the two buildings had to be matched to an existing building on two different levels on a sloping site, abutting an existing building on one side and with very little clearance on the other. To further complicate matters, there was very restricted access for the large crane required. Marathon completed the job with minimum fuss and within the programmed time and budget. I could not recommend them more highly."

Canberra Grammar School

"Marathon completed the construction of our new Junior School Building. This building consisted of 4 classrooms, a breakout space and offices. Throughout the construction and pre-construction phase Marathon assisted us in understanding restrictions and options available to us. The team were also co-operative with regard to enabling “school contractors” to undertake works concurrently with the installation of the modular building. We are delighted with the final product. It is a versatile and flexible learning space."
