Innovation on Site Masterproject Construction Technology 7RC50 Innovatie op Locatie, or Innovation on Site as it is called now, has been and still is a showpiece of how to implement the workfield of the Built Environment into university education. For the first time in the history of IoS, a whopping nine construction companies participated , by providing interesting construction sites with even more interesting problems or challenges. In this article one can find a short description of all the nine groups.
Nine groups have been able to attend the course Innovation on Site 2016. For us to be able to have nine companies providing decent challenges for our students to analyse, was a challenge on itself. As every year, Bouwend Nederland, has assisted us in providing nine construction sites, and collecting a proper jury. In this jury, this years chairman, Raymond Vaessen, director of Van Wijnen Sittard B.V., was able to lead the jury as a true expert. Heleen Herbert, CEO at Heijmans, was able to give very good remarks. As an expert on construction site safety, Adri Frijters, was also part of the jury and focussed in judging the groups more on

his profession. To make a complete jury, Erik Vastert, former responsible lecturer in Construction Technology at the TU/e, now was part of the jury, as the expert on IoS. Because of the huge amount of groups, attending the course IoS, a preselection was necessary, where five out of the nine groups were nominated for winning IoS 2016. These finalists, on the 8th june, held presentations in the Zwarte Doos for an audience, companies and of course the jury.

Group 1: Era Contour | TBI - Queeckhoven/Mussen en Merels Lex Hermens & Mike van der Linden In Utrecht, contractor ERA Contour|TBI is realising a housing project that consists of 117 houses. The houses are constructed with a conceptual building method called WoonLab. With this concept a lot of prefabricated concrete elements are used to make the structural works. Windows and window frames are also prefabricated in the structural wall elements. The floor is made with hollow core floor slabs. Due to this, the structural work of a block of houses can be made within a matter of days, creating an almost air tight structure. Ventilation of the houses is hard after this point, because the windows cannot be opened. This leads to water accumulation in the hollow core floor slabs. By using methodical analysis techniques a solution for this problem is attempted to be found. This eventually led to five possible solutions which are graded in terms of building quality (is the problem

solved), safety/heal risks, time and costs. A solution where the hollow core floor slabs are protected from external conditions proved to be the best. This solution also included an innovative idea for a dry mechanical connection between the hollow core floor slabs and an alternate scaffolding system. Innovative clamp

Group 2: Van Wijnen - DC Bol.com Philip Groeneveld, Yaron Moonen & Sahand Asgarpour Constructing the new Distribution Centre (DC) of bol.com with a surface space of 135.000 m2 (26 football fields) in eleven months, is the task that ‘Van Wijnen’ has for their client Bol.com. This new DC will be built in Waalwijk and will prepare Bol.com in the nearby future for an increase of the amount of goods sold by e-commerce.
Construction site Bol.com
To construct such a gigantic building in this small time period is an enormous task and demands a lot deployment of the building team. It was for this reason that Van Wijnen asked us to have a look at the building process and find out if there are possibilities to improve workflows, and if possible accelerate the construction process. Our investigation hereby was mainly focused on module 2 and 3, the parts of the building that provide the warehouses of the DC. After making an investigation with different cases to improve the building process we came to the conclusion that the main problem is that all activities are working one after another, and that makes the building process long and sometimes chaotic. So what our solution provides is a prefab element where they can build in an early stage of the construction process the Entresol floors or system floors (a separated construction that is placed in the building) in module 3. Where at the same time they construct the normal workflow in module 2. By doing this they could
1st place not only save four weeks of construction time, they split the two main workflows from each other so that they can’t conflict each other anymore. By doing this it provides a better a quicker way of constructing the warehouses and it helps to reach the deadline in time.

Group 3: Jongen - Meulen | Volkerwessels - Jazz City Roermond Nominated
Jan de Boer & Rob Claessens For the project Innovation on Site we were sent to Jazz City in Roermond. This is an expansion of the Designer Outlet and will be a new dynamic centre with apartments, entertainment, restaurants, cafés and shops. It will attract 7 million visitors each year. Because of a delay of three weeks, caused by some mistakes by the structural engineer, two problems will occur. One of the cranes, that is placed in another block of shops, will not be removed in time, therefore starting
the construction of this block will be delayed as well. Also, props that are placed in future shops, which are needed to support the scaffolding on top, will be removed too late. This means that the shops won’t be handed over in time. This all leads to not finishing the shops before the deadline, which will result in high fines of € 1 million per day. For both problems several solutions were developed after which the best solution was chosen. For the problem regarding the crane, the best solution is to use a mobile

crane instead, at another position, to finish the crane activities. For the second problem using a suspended scaffolding was a good solution. Another solution, which is easier to execute, would be to use an innovative temporary structure to make the use of props redundant. For us it was a nice experience to spend a whole week on a construction site. It provided us with more insight in the working practice in reality. A fun but exhausting week.

Group 4: IQ Woning | Ballast Nedam - Weert Stefan Werner, Luuk Titulaer & Meruyert Albagambet We as team 4 were assigned to the iQwoning® factory site. iQwoning® is a company which has accomplished to combine the automotive industry with the building industry. The basis of this unique concept begins with the manufacturing of six high-quality concrete elements, which in time can be assembled

to a iQwoning®. Currently, iQwoning® has seven concrete moulds in their possession that are able to manufacture seven elements a day. iQwoning® is planning to increase their production capacity, so they have purchased another four moulds. This will increase the production capacity to eleven elements a day. Our task was to research and observe the current logistic situation of the production process (seven moulds) and to inventory any existing and expected bottlenecks. After a week of observation and investigation, we had formulated the following problem definition: “In future situation, when up-scaling the production capacity, the capacity of the element crane is too low.” The crane mentioned in the problem definition has to make four movements for each element, which in total takes approximately 40 minutes. Multiplying this time with the desired production of 11 elements a day in the future, results in almost 8 hours of crane usage.
Nominated The solution we have created for this problem enables the crane to skip one movement and thus reduces the element crane usage. Our solution is realised by making a modification, which pushes the element on a trolley instead of lifting it with the crane. The solution is expected to reduce the necessity of the element crane by 30%. In addition, we have calculated that the investment of this modification will be earned back within 5 years. This whole project was a big and interesting challenge for our team, which we managed to cope with. We have gotten valuable knowledge on how the factory for prefabricated elements works.

Group 5: BAM - Kennedytoren Remco van Roestel, Berenisse Hernandez Quinones & Shai Nahum Corrales Silva construction process, especially when a lot of different parties are involved. By creating a standard protocol, everyone knows how to check their work. For the management it will also be easier to keep an eye on the subcontractors, by being able to follow the development of their work step by step. The improved way of communicating will also result in faster decisions on site, regarding small obstacles, but for instance also large RFC’s.
Relocation HERE Eindhoven is a large reconstruction project of seven floors in the Kennedy tower. The project was assigned to the company BAM in December 2015. The building costs will be around 3,8 million euros, which puts the project on the separation line between the maintenance department and the construction department. The construction is characterized by a very short building period (January - April 2016), a client that changes a lot of design aspects during the construction, and the full responsibility for BAM as the general contractor. After a very intensive construction period, BAM is almost done with this project. After the 28th of April, HERE moved in their new office, while there is still some remaining work to be done. Originally, a fine of thousand euros a day was set for any delay. However, since HERE was able to move into their new office, and considering the large

amount of design changes, the fine has not been applied. The aim for the presented solution is to show new and more efficient ways to organize the

Group 6: Stam + de Koning - De Groene Toren Kay van Meerwijk, Thomas Dam & Mario Santamaria Puga After two days of roaming and analysing on the Space-S project in Eindhoven, the project group asked the supervisor if the unclear problem definition could be taken into an extreme case, having no construction site at all. One of Stam + de Koning new building projects is De Groene Toren at the Vestdijk in
Eindhoven. The façade will be replaced by new façade panels and the interior will also be refurbished. The problem analysis results in the importance of the transport on site of all several building elements. Various crossing transport chains of export and import of building material in the 14 storeys tower need to be coordinated. The safety of the pedestrians and traffic is another aspect on this project. The transport plan and the safety come together in the assemblage of the new façade panels. If the assemblage takes too much time, the storage of the panels becomes too large, which gives risk
of damage. Moreover in the current situation the use of a safety net attached to a scaffolding impedes the montage as well. The solutions of these problems concern the coordination of the transport chains and improving the assemblage using a specific transport- and assemblage systems as indicated in the images. The safety will be guaranteed by a self-climbing scaffolding system with a curtain wall. Due to the safety it is only happening at the height where the scaffolding is at that moment. After all the project was very interesting to get in touch with Stam + de Koning and also the learning process about problems on the construction site.

Group 7: Huybregts Relou - Student housing TU/e Francisco Jose Bernal Ferrer, Renée van der Wurff & Patricia-Alexandra Diaconu A case study on the water penetration problems existent in the Student Housing project developed by Huybregts Relou in Eindhoven (The Netherlands) is presented in our report. Water infiltration resumes to penetrate through the installation shafts and between joints as well as caused by the existing water in the construction materials. After a comprehensive analysis, a shaft covering presents itself as the best possible solution for our problem on site according to the criteria stablished. Although this solution does not cover the criteria about preventing water penetration through joints, it prevents water coming inside through the shafts (intended holes) until the outer shell is finalized. Considering the fact that our contact on site gave more importance to the water penetration through the shafts, it makes sense to give a higher priority to this criterion and therefore to this solution. About the material, biodegradable material

appears to be the green solution as it is an option that will not need any removal. This is due to the fact that the material applied will disintegrate in the end. On the other hand, it is considered an experimental material, more expensive in comparison with other petroleum based plastics. Hydrophobic material is on the other hand a more economical solution. Nevertheless, once applied it needs to be removed by hand when pipelines are installed through
the shafts, which adds an extra requirement in the building process.

Finally, in terms of performing the research we can conclude that the on-site experience gave a very good understanding on the cause of the problem. Also, the discussions with the experts on site (site engineer and technical engineer) made the building process and the damages caused by the problems clearer. The problem analysis methods helped us to better map the roots of the problems and their implications. Lastly, the criteria based system and the morphological map helped us combine
Group 8: HBO- Bloemenbuurt Zuid Miryana Stancheva, Glenn Pennings & Maria Camila Duarte Due to the unfeasibility in renovating Bloemenbuurt-Zuid, the authorities chose to redevelop the area. The housing company however, demanded that the social structure remains preserved. Hence, a Collective Private Commissioning-Cooperation was initiated, in which the future inhabitants (buyers of the plots) were actively co-developing the housing design, which co-development happened within the boundaries set by the municipality and the housing organisation. Regardless of the set boundaries, the clients

had the freedom to choose between three types of extensions for their properties. Subsequently, the freedom of choice resulted in the variation of depths in the façade surface in each storey and between the different storeys of the total structure. After analyzing the situation on site from several different perspectives and with the help of tools such as the Ishikawa diagram and the Porras stream analysis, we managed to discover that the reasons why the current scaffolding system doesn’t comply with the needs on site are several. Firstly the problem can be divided into two main sub-categories and namely, managerial (cost-oriented decision making) and technical issues (low flexibility of the scaffolding system). The managerial aspect refers to the decision making procedures of the company, whereas the technical aspect can be further broken down into three different categories, namely problems due to fixed sizes of scaffolding platforms, distance to the façade bigger

Each from the aforementioned problems was tackled separately where for the managerial part the solutions were presented in the form of recommendations for the future, based on hard data and comparison of prices. The uneven surface resulting from the overlapping of the wooden planks was solved by the use of rubber covering (usually used to protect cables). The other two technical problems were tackled by the implementation of two types of slidable metal platforms, one adjustable in length and the other – adjustable in width.

Group 9: Hurks - Blixembosch Buiten Omar Abdelghaney, Maria-Niki Kravari, Marleen van Wanroij Spending a week on the Hurks Blixembosch Buiten site was a unique and highly educational experience. Apart from gaining firsthand valuable site knowledge, we were exposed to real life practical problems that Hurks faced on this particular project. In our
Construction site Blixembosch buiten
case, we were asked to find solutions for Hurks’ problem of being forced to build the 16 townhouses of the project horizontally instead of vertically due to logistics, structural and architectural issues, as well as subcontractor demands. The reason for this is that Hurks gets paid for a house according to the construction progress of that house. Therefore, they wanted the houses to be built subsequently in order to be able to start recouping their money as early as possible rather than in one big bulk in the end. In order to make this possible we suggested architectural changes for some elements, some traditional and some innovative structural options, as well as logistics and subcontractor solutions. These solutions would allow Hurks to manage to build vertically, improve their rate of return on their investment, as well as cut down on construction time by over 50% for one house, and over 7% for the total
project. In the end, finding a solution was a long and difficult process for us as it had to be tailor made for this particular project, as well as be cost effective and innovative. We are glad we were able to experience this process and gain insight by seeing how the theoretical work was applied on site. We want to thank Frank Stoop for his time and effort to help us with our project, as well as Cor de Bruin for his supervision over the project and for the advice he offered us during the time we worked on this project.
