In the fall of 2018, Arjan Bassie approached AAB to discuss the possibilities regarding project management of the Syngenta new-build R&D tomato greenhouse project in Maasland. Arjan: "After a couple of discussions, we decided that AAB would provide support in the permit phase, the design phase, the tendering phase and the construction phase. AAB was already well known to Syngenta for the supervision of various projects. That gave us confidence for our cooperation in this project."
Maik Rodenrijs, AAB: ”The major challenge in this project was primarily to arrive at quick and clear starting points within the available time. The aim was to have potential building partners to quickly start the cost calculations, with which an agreement could be concluded with each party. Finally, a speedy lead time was required. Which means a tight schedule. In mid-December 2019, the planting had to be started in the unlighted greenhouse."
One of the priorities was the practical translation from the idea into the design. Arjan and Syngenta regularly coordinated with each other. And at the same time they started looking for construction partners. Collaboration would become the key to success.

Because there was no time to lose, the tendering phase was arranged slightly different. Apart from two disciplines, no drafting of technical specifications, but of clear functional descriptions, in order to arrive at concrete quotations. Parties were not only assessed on the financial aspect, also the quality, capacity in labor and materials were important award criteria.
Different disciplines are needed within such a project. Maik: "Both large and small, all in proportion, but none indispensable." The largest construction partners within this project are:
- Technokas - Greenhouse, heating, the demo room
- Stolze - Water, electrical installation, lighting
- Huisman Scherming - Screen and insect screen installations
Construction partners
By combining different disciplines under one company/construction partner, efficiency and coordination have been improved, as all parties agree. Although each discipline is represented by its own project manager, the lines and coordination are short. This resulted in a fast realization design. Despite the ‘regular challenges’ such as delayed deliveries, weather conditions, et cetera., there will be planting in the high-tech tomato greenhouse in mid-December.
Stolze - water, electricity and lighting
Arjan Bassie and Carel van Ruijven (Stolze) have known each other for a long time. And that is, of course, pleasant. Carel: "With this project we had an extra challenge because it concerned the wishes of both Arjan (owner) and Syngenta (user). We finally came up with a complete electrical, water and grow light installation."
Due to comparable tests, Syngenta has opted for a conventional SON-T lighting installation, which uses Industria luminaires 1000W with a so-called 'deep reflector', 4 per girder. This amounts to approximately 190 micromol (1 light fixture per 10 m2).

Huisman Scherming - screen installation and insect screen
Arjan Bassie and Dave Boer (Huisman Scherming) have also known each other for many years.
The objective ahead of time was to integrate as much as possible into the greenhouse structure. In a short time, a great deal of preparation was done previously with the construction partners. Dave: "We succeeded well with the screening installation and the insect screen."
Arjan Bassie and Syngenta have opted for insect screen type Multi-Fold: "This screen stops as many external influences as possible. That is important. The breeding process must take place as accurately as possible to achieve a good result. And this screen is going to be part of it."
Screen and ventilation motor
A clear Luxous 1147 FR energy screen is installed in sections 1-2, 3, 4, 7 and the corridor. This screen has been chosen for energy saving. And due to the high light transmittance, this cloth can also be used during the daytime on cold days.
Sections 5 and 6 are the lighted sections. A light-reduction cloth type Obscura 9950 FR W is mounted there, which is mandatory against light emission. This cloth also provides a 50% energy saving.
A Harmony 5220 O FR cloth is installed in the demo room. The greenhouse roof is fitted with double glazing. The preference here is for an open structure diffuse sun screen cloth. This will be used during too much direct radiation and on hot days. The screen can then be closed completely and still allow ventilation.
Technokas - the greenhouse
Technokas, together with AAB and Arjan Bassie, devised this integrated greenhouse. Maurice Hartman, Technokas: "The greenhouse departments and demo room were already well developed in the preliminary stage, but there was sufficient freedom of movement for the right fine tuning.
For the central heating installation we have been able to contribute a great deal of knowledge in the preliminary phase and an integral design has been made where all disciplines are aligned. During the coordination meetings, all installations were discussed openly on the basis of detailed drawings."
Construction was then started and the project was properly coordinated with the partners in a biweekly planning meeting. In this way the entire building could be realized smoothly through pleasant cooperation. Technokas: "It results in the delivery of a state-of-the-art horticultural project, where the tomato plants will be planted before Christmas."
