Bostoen and Gillion, a winning combination

Bostoen is delighted with the work carried out for the Alida development (7 houses and 38 apartments) and is to continue its partnership with Gillion. The first stone of a second residential project will be laid in January 2020, in Forest.  

At the junction between Rue du Delta and Avenue Van Volxem, in a neighbourhood where city and nature mingle, the new project, which is to start in January 2020, will last 330 days. Bostoen has entrusted Gillion with the structural and finishing work that includes six single-family houses, the Forestine Residence with fourteen apartments and nineteen parking spaces and the Pauline Residence with twelve apartments and twelve parking spaces.  

For the Alida project, Gillion understood and responded optimally to the client’s needs thanks to a lean approach. Lean Manufacturing is the western version of the Toyota Production System and aims to refine the execution process. The schedule is precise and execution as efficient as possible. Rather than labour saving, it’s about avoiding wasting stock and production waste. Here again, Gillion will carry out different stages at once by starting the finishing work before the structural work has been completed. Thanks to lean manufacturing, Gillion can therefore set up worksites that reflect ideal execution.  

It should be noted that Bostoen, acting as developer, is planning to renew its trust in us with the third phase of the development. The feat continues for both companies, while in the lush atmosphere of Forest, a neighbourhood is undergoing a major transformation, in perfect harmony with its surroundings.

Gillion contributes its expertise to a charitable project

The first stone of CREB2 was laid on the 22nd of January. This day centre for children with multiple disabilities, is located in Anderlecht and will complement the one in Woluwe-Saint-Lambert that currently accommodates 55 children.

An entirely passive, prefabricated building with a wood and steel structure! Thanks to the generosity of charity organisations, such as the Rotary Club or Cap 48, and significant funding from the Brussels Region, this wonderful project will soon be able to accommodate 30 children who, up until now, spent up to five hours travelling between the centre in Woluwe and their home. The non-profit organisation CREB has found a prime plot on the Erasme Hospital site to the north-west of Brussels: a location that will make life much easier for the children and their families by limiting travelling time.

This project therefore fulfils a genuine need, but several significant partners have been called upon for funding as the overall cost (construction and equipment) is estimated to be €3,650,000. With planning permission granted, the specifications approved, and a long-term lease for a ground rent of €25,000 per annum, the works can now begin! We are proud to contribute to this vital operation.

Gillion breathes new life into the Samusocial

For Gillion, construction work also serves a social and societal purpose. The Brussels company will soon be renovating the Samusocial headquarters in Anderlecht. A mission that they take pride in.  

For almost four years, the Boulevard Poincaré in Anderlecht has been welcoming homeless people in a former office building belonging to the Brussels Region.

This centre for vulnerable people is in dire need of renovation. After a call for tenders to renovate and improve the building, Gillion’s bid was selected.  

Considering the complexity of the project – mainly due to the need for major refurbishment in a dense urban fabric – it was Gillion’s experience that sealed the deal. The company, whose main constituents are based and very active in the Brussels-Capital Region, has shown that they know how to deal with such constraints. The team has already participated in numerous public social housing and healthcare projects. These experiences are put to good use in the Samusocial project.

In this Design & Build market, Gillion’s partners are the Altiplan architectural firm, TPF and PS2. This team is highly motivated and determined to offer decent accommodation to the disadvantaged. Needless to say, it is of primary importance for Gillion to enable Samusocial to function comfortably. Once the permit is granted, the construction site should be completed in 2021 after roughly 150 days of work.

Gillion celebrates 2019 with its staff

As usual at the end of each year, Gillion brings its staff together for a winter barbecue. An opportunity to celebrate the past year and look to the future. This year, the festivities will take place at the Kontich headquarters.  

2019 was a special year for Gillion. Not only did the construction company celebrate its 100th anniversary (yes, that’s right!), but it also underwent a complete makeover by entirely revamping its brand. It is at that anniversary party that employees have shown their new worksite jackets bearing the new logo.  

We mustn’t forget that 2019 was a year of many successes for the company. Gillion rose to the challenge at Pairi Daiza, Europe’s largest animal park. A new World, the Last Frontier, was built adhering to a strict deadline to ensure that the new part of the park could open at the start of the season. Mission accomplished!    

At 100 years of age, the Gillion company appears to be outstandingly youthful. It won the Trends Gazelles trophy in January and a victory at the Green Solutions Awards. At the opening of the Batimat Trade Fair in Paris, Gillion received the Health & Comfort prize for innovation at the IBGE forestry brigade site in the Sonian Forest.  

As a family business, keenly run by the fourth generation, Gillion is committed to continuous improvement while maintaining a human scale. Whether for colossal sites or smaller missions, the objectives for 2020 are unchanged: listen to customers, innovate, be efficient and respect the environment while considering energy performance and the reuse of materials. 2019 was yet another springboard year. Gillion intends to celebrate it with those that make it all possible.
