IJburg is a large-scale urban development project on the outskirts of Amsterdam, the Netherlands. Where the territory of Amsterdam reaches the IJsselmeer, the biggest lake of the Netherlands, a major urban extension with a size of 220 ha and a population of more than 22.000 is being developed on artificial islands which have been raised from the lake. This means that the existing natural functions and requirements of the water system needed to be taken into consideration in the development of the district. Both the first phase of IJburg and the second phase, in enhanced form, seek to work in harmony with the surroundings; an extraordinarily high density of up to 90 homes per hectare, ensuring preservation of the quality of the water in the IJsselmeer, alongside a high aesthetic appeal. Because the development is on islands, which also have waterways cutting through them, then naturally water has to be a main consideration when developing the site.

Challenge

Via Milder, producer and importer of plastic pipe systems, Walraven received the request to develop a pipe support system. For this project ground-coupled heat exchanger systems were installed for residential use and large diameter PE pipe-work had to be constructed for the transportation of heat and cold water. Ground-coupled heat exchangers use the earth’s near constant subterranean temperature to warm or cool the water, a viable and economical alternative or supplement to the conventional central heating in the properties of this project.

The solution

One of the main reasons why Kersten Retail, the main contractor of this project, selected Walraven as supplier was that, besides their technical expertise, our technical engineers use Revit^® software for their designs. Using Revit^® software our engineers produce consistent, coordinated and complete model-based designs and documentation. By using the integrated BIM models specifying the Walraven products they can develop effective and high quality pipe support solutions for the diverse pipe installations and detect clashes on-time. This does not only result in safety and ease of use, but also prevents waste, failure costs and expensive corrective measures. For the IJburg project our engineers created the pipe support design in a separate Revit^® file that linked to the master file that Kersten Retail sent to us, specifying the building- and installation design of the project. Once approved, the solution drawings were communicated to our in-house prefabrication service department for assembly. The design ensured fast and precise assembly, ensuring time and cost saving on site.

What makes this project also real special is that the Walraven Aerofoam^® NBR insulation rolls and sheets were applied. This highly efficient closed cell foam offers high thermal efficiency and protection from imminent condensation problems. Due to the little space at the building area the insulation company decided to first apply the Walraven Aerofoam^® NBR insulation on the PE pipes and the distributors of the installation and then transport the prefabricated parts to the construction site. Not an easy job. Due to the excellent mechanical strength of the Walraven Aerofoam^® NBR insulation foam nothing was damaged and the high insulation value was retained. No need for repairs, no loss of time!

The Problem

This was a rooftop installation project to support very heavy pipework. The solution had to take into account several factors:

• It had to be suitable for outdoor use
• The thermal expansion of the pipework
• Allow for a non-penetrative roof design
• Be easy to install in a confined space

The Solution

Our technical support team provided drawings and load calculations to recommend a combination of Walraven installation systems. This was followed up with a toolbox talk on-site.

The Walraven Maxx frame system is perfectly suited to supporting heavy pipework and is suitable for outdoor use. Used in combination with our expansion guides, the pipes would be effectively supported whilst allowing for thermal expansion. To provide a non-penetrative rooftop attachment, our Walraven Yeti® rooftop support feet were used.

The Walraven Maxx frame is a flexible, heavy rail system that is safe, secure and corrosion resistant. It is suitable for many applications and is quick and easy to install without the need for on-site fabrication or welding – perfect for confined spaces.

The problem

Large pipework in the basement required supports allowing for expansion, as well as fire stopping of the pipe penetrations through firewalls to ensure safety of fire escape routes. There were a number of different substrates and arrangements that required solutions, along with the added issue of pipe expansion and contraction. If pipe expansion and contraction is not correctly considered when installing a fire stop, the movement of the pipe could render the fire stop ineffective over time.

The Fire Stop Solution

Walraven’s range of fixing points and slide guides were ideal for fixing the large pipework system, whilst allowing it to expand and contract. The Walraven Pacifyre® MKII Fire Sleeve was recommended for fire stopping. It is unique in that it allows pipes to expand and contract without compromising the effectiveness of the fire stopping – unlike fire collars which hold pipework static, preventing the pipe from expanding freely, potentially resulting in failure. Walraven provided technical advice, design solutions and on site support for this project.

Problema

Healthcare ne-a rugat să lucrăm împreună pentru a găsi o modalitate de a monta cât mai rapid instalațiile mecanice în proiectele lor de cămine de bătrâni. Având în vedere numărul mare de proiecte de acest tip, timpul economisit cumulat are un potențial substanțial.

Soluția

Am recomandat sistemul nostru Walraven RapidRail® ca soluție rapidă și flexibilă. Asta a inclus și gama de coliere cu garnitura verde, perfecte pentru rețelele realizate din țevi din plastic unde există dilatări.

Cu avantajul prefabricării în fabrica noastră, am putut livra module pre-asamblate pentru instalare imediată. Pentru a realiza acest lucru ne-am ocupat de toată partea de calcul pentru întreaga clădire, luând în considerare țoți factorii, cum ar fi dilatarea la trecerile prin încăperi cu temperaturi diferite.

Colaborarea încă de la început în astfel de proiecte este importantă, pentru a asigura schimbul de informații exacte din care să rezulte soluțiile ce pot fi aplicate. Informațiile corecte sunt esențiale pentru a fi siguri că ansamblele prefabricate se potrivesc perfect în configurațiile finale ale construcției.

Într-un astfel de cămin din Londra, întregul parter a fost gata în 1,5 zile. În mod normal, instalarea ar fi durat 1-2 săptămâni. Gavin Hayes – Project Manager la Heatcare a comentat:

“Walraven RapidRail® este sistemul nostru preferat în proiectele de instalații. Este un produs de calitate ce se instalează rapid și ușor. Am economisit 150 de ore de lucru folosind acest sistem. Am folosit de asemenea designul Walraven și serviciile de prefabricare, ceea ce au ajutat ca proiectul să meargă ca pe roate. Recomandăm cu căldură produsele și serviciile Walraven”.

Problema

În locație exista foarte puțin spațiu pentru instalații, pentru care trebuia găsită o soluție. Trebuia instalată o rețea de ventilație complet funcțională. Dar nu se puteau prinde de pereți sau pardoseală. Atunci Avantor a rugat Walraven să găsească o soluție.

Soluția Walraven

Soluțiile noastre ”clasice” Walraven Yeti and Walraven Urus nu au putut fi aplicate aici, de aceea am apelat la cel mai robust sistem al nostru: Walraven Maxx. Cu acest sistem am instalat canale mari de ventilație în mai multe rânduri unul peste altul. Acestea au fost legate de structura clădirii pentru că pereții și pardoseala nu erau disponibile.

Noi fiind producătorii acestor produse, am putut livra tot în mai puțin de 48 de ore. Astfel, clientul a economisit din timpul alocat instalării. Pe lângă aceasta, Avantor a fost foarte mulțumit de faptul că noi am pregătit și organizat totul. De la estimare la execuție, noi am oferit toate informațiile pentru a se executa această lucrare.
