Advising De Werkvennootschap

Flanders is coping with huge mobility problems, as seen around Brussels and in Flemish Brabant. Therefore, the Flemish government has decided that all major mobility projects will be coordinated through one organization.

To that end De Werkvennootschap was founded early 2017. This overarching project leadership helps realize infrastructure projects more quickly.

Mirjam Cauvern advises De Werkvennootschap on organizational aspects and supports the drafting of an organization plan, so “De Werkvennootshap” can perform its function as best as possible.

The value of underground development

The underground can make an important contribution to rendering the Netherlands more liveable. For example, there is often too little space in the overground urban environment to fit projects into it. The underground can lead to a solution there.

Building underground is often associated with high costs, complexity and risks. Then again, there are many benefits that can be realised, like improved accessibility, improvement of the quality of the local environment and more surface space for other purposes. Sometimes, unexpected benefits emerge afterwards that had no influence in the decision making.

By carrying out an analysis of social costs and benefits of realised underground projects (ex post) and an analysis of the decision making and argumentation thereabout (ex post), the actual (added) value of underground space use is made clear. With this goal in mind, the Knowledge Centre for underground development and underground space use (COB), in coorporation with Triple Bridge and other parties, has started a project in which 10 to 15 realised underground projects will be evaluated.

The results will be translated into a conversation framework for directors to better weigh up the choice for an underground solution. In addition, the results are input for urban designers (benefit-targeted design).

Lidwien Besselink manages this research project. More information about the research programme can be found here [in Dutch].

Review IC direct

The reliability of the national high speed line between Amsterdam, Rotterdam and Breda with the Intercity direct (IC direct) is insufficient. Moreover, it has decreased over the years.

ProRail and NS have drafted plans for improvement. Their goal is to improve the punctuality and reduce train cancellations.

Commisioned by the ministry of Infrastructure and Environment, Triple Bridge, in collaboration with Railistics, has tested the effectiveness of these plans.

In addition, the review team, directed by Mirjam Cauvern, compared the achievements of the IC direct with respect to those of other transporters on similar routes abroad.

Based on the results of the review, the ministry wants to make ambitious yet realistic agreements of performance with NS and ProRail. The results also provide the basis for potential investment decisions.

Final phase The Central Axis

The Central Axis is a project concerning the construction of a two-lane highway from Dokkum to Nijgega.

Task area development

On the 7th of October the road has been festively opened. The attention of the project organisation now turns to the task of area development.

The province Fryslân feels the need for an action plan in order to develop the project organisation of this final phase of the project of the Central Axis. Mirjam Cauvern and Elizabet de Graaf will compose this plan.

Desired project organisation

The action plan will include among others the scope of the integrated area development, the structure of the project organisation, a description of the consultation structure and workflow, a description of the required capacity and the desired official and administrative placing of the project. Furthermore, attention will be given to the transition from the current project organisation to the desired project organisation.

Project management solar installation

solar installation

The roof and parking deck of the former office of the Central Statistical Office in Heerlen will be paved with solar panels. Rooftop Energy and Walas Projects will realize this together. At the end of 2016, the solar panels on the roofs will produce energy. In the course of 2017 the solar system over the parking lot will be ready.

The parking deck will also be equipped with a water basin that will be used to catch and re-use rainwater. The sustainability of the parking deck will be further improved by replacing the current lighting with LED lights, and by redecorating the place with a sustainable design. Finally, there will be electrical charging outlets for both cars and bicycles, to encourage sustainable mobility.

Part of the office building, nowadays called Carbon6, is a national monument.

Elizabet de Graaf takes care of the project management for the preparation of the realisation of the solar installation and the related works.

Knowledge inventarisation water specialists WNZ


Rijkswaterstaat Western Netherlands South (RWS WNZ) controls a very diverse waterway network. Water safety and water management have a prominent role in this network. Specialised knowledge of water is deployed in both urgent situations (for example, when a decision must be made in case of imminent flood) and for measuring effects on the long term (for example, to determine the consequenses of emissions on the ecosystem of rivers).

Commissioned by RWS WNZ, Triple Bridge is working on an inventarisation of the present and required specialised knowledge of water. This inventarisation further substantiates the ambitions of Rijkswaterstaat on knowledge management.

For more information, please contact Nicolien Vrisou van Eck or Elizabet de Graaf.

The Oosterweel link

Oosterweelverbinding Beheersmaatschappij Antwerpen Mobiel Triple Birdge

The ring of Antwerp is amongst the busiest traffic junctions in Belgium. It is prone to congestions, among others because the ring road is not closed. At present the Antwerp region has two motorway connections between the river Scheldt left and right bank: the Kennedytunnel and the Liefkenshoektunnel.

A third tunnel underneath the river north of Antwerp, the Oosterweel link, will round off the ring of Antwerp and should solve the current structural mobility issues in the Antwerp region. The Beheersmaatschappij Antwerpen Mobiel (BAM) is responsible for this project.

Because of the unique character of the project a tailored project organisation is necessary. Triple Bridge will support BAM in shaping the project organisation for the execution phase of the project Oosterweel link.

Implementation Programme Sustainable Subsoil Use Flevoland 2016-2020 initiated

Uitvoeringsprogramma Duurzaam Gebruik Flevolandse Ondergrond Elizabet de Graaf Triple Bridge

On behalf of the province of Flevoland, Triple Bridge has supported the formation of the Uitvoeringsprogramma Duurzaam Gebruik van de Flevolandse Ondergrond (Implementation Programme Sustainable Subsoil Use Flevoland or UP DGO) 2016-2020. This Implementation Programme has been established on the 1st of March 2016 by the Provincial Executive of Flevoland.

Induced by the results of the Interim Review performed by Triple Bridge, the new Convenant Bodem en Ondergrond (Convenant Soil and Subsoil) 2016-2020 and the Coalition Agreement 2015-2019, the wish was expressed to update the UP DGO in Flevoland.

Triple Bridge has supported the implementation process, through a successful meeting with local partners, and has provided substantive information on the matter of sustainable use of subsoil. Together with the local partners, the province of Flevoland will develop the formulated ambitions, by the motto ‘Oriented smart, investing together in the Flevoland soil and subsoil’.

Results investigation smoke and fire alerts Schiphol railway tunnel

Schipholspoortunnel Brandmelding onderzoek Triple Bridge NS ProRail Veiligheidsregio Kennemerland

In recent years ProRail has taken many measures to reduce the amount of fire and smoke alerts in the Schiphol railway tunnel. Commissioned by ProRail, NS and Veiligheidsregio Kennemerland, Triple Bridge has investigated the effectivity of these measures. Triple Bridge also has inventoried the possibilities to further reduce the number of alerts and its impact on the timetable.

The number of fire and smoke alerts in the Schiphol tunnel has been declining since 2013. Many measures have been implemented to reduce alerts and their impact. Triple Bridge concludes that – despite the measures implemented – smoke and fire alerts will always occur. The causes of the alerts are diverse, making it difficult to further reduce their number.

The safety procedure dictates that in case of fire or smoke detection the entire tunnel must be closed for all rail traffic. The consequences greatly affect the timetable and are far reaching for passengers. Triple Bridge concludes that the procedure does not provide enough space to deal adequately with fire and smoke alerts. Advantage is to be gained in faster starting up the schedule after disruption by a fire or smoke alert.

Based on these conclusions Triple Bridge made a number of recommendations. For more information, please contact Mirjam Cauvern.

Results study PPP Flanders

Commissioned by the Flemish centre for Public-Private Partnership, Triple Bridge has examined the infrastructure-investment policy in Flanders. A group of experts operated as sparring partners for the research team.

The research team analysed the available instruments in all the stages of the process and so captured the process of public infrastructure investments in Flanders. This way insight on contemporary knowledge and expertise in the field of realisation of large infrastructural projects in Flanders was gained. Besides that the best practices and bottle necks typical for Flanders have come forward.

There has been concluded that many instruments have been developed in Flanders to realise projects. By focussing on the lessons from the past and the division of knowledge between several sectors the set of instruments can be improved to a general appropriate guidebook for the realisation of infrastructure projects.

The research team has proposed to bolster the missing knowledge, instruments and processes. By international examples Triple Bridge has shown in which direction the development of instruments can be sought.

Risk review of the Riyadh subway

Risico review metrobouw Riyad

FAST, an international consortium in which Strukton participates, is now realising three subway lines in Saudi Arabia’s capital Riyadh. Risk management plays an essential role in the successful execution of this project (within the financial and scheduled conditions).

Risk management provides insight in important factors that threaten or improve the success of a project. It also assures that one is aware of the risks of a project and communicates about them. Above all, based on risk analyses more measured decisions can be made and improvements established.

To get a clear view of the quality, lay-out and the application of the risk management, Marcel Hertogh and Nicolien Vrisou van Eck produced a review at the consortium in Riyadh. Points of interest are the intern and extern context of the project and the room for improvement in the project organisation. The review has resulted in the desired prospect for risk management and the starting point to achieve this.

Evaluation program durable soil Flevoland


On the 5th of June 2013 the Provinciale Staten van Flevoland certified the Nota Duurzaam Gebruik van de Flevolandse Ondergrond 2013-2017. The aim of the province of Flevoland is that by 2025 inhabitants, companies, and governments make use of the soil in a more conscience and ecological way. To stimulate the ecological usage of the soil in the province an execution program has been issued. The program now runs for two years and is halfway through its lifetime.

The province of Flevoland has asked Triple Bridge to map out the results of last two years. A distinction is made between progress relating to the content, in means of process and finances.

Lidwien Besselink and Tanja Manders produced the mid-term evaluation. The mid-term evaluation report provides input on the further configuration of the follow-up trajectory, about which the Provinciale Staten in the autumn of 2015 will decide.

State support test for the Energiefonds Utrecht

Triple Bridge has evaluated for the Energiefonds Utrecht if, in case of a funding request for a durable energy company, there could be question of clandestine support from the state.

For this task Ingrid Dolmans-Budé determined the juridical frame and subsequent Julia Padberg established a financial model to calculate if the anticipated state support is within the legal limits. Two scenarios were assessed: one in which the total sum of the credit facility was not used through the years and another one in which the committed sum was fully consumed throughout the whole run-time of the enterprise.

In both circumstances it turned out the legal limits were not exceeded and thus there was no question of clandestine support from the state. Meanwhile the Energiefonds Utrecht has provided the fund.

Life Cycle Costing in the HWBP


The Hoogwaterbeschermingsprogramma (HWBP) applies the method of Life Cycle Costing (LCC) to come to the solution with the lowest total costs for the primary flood barrier, based on the total (planned) lifespan.

To facilitate the deliberation of alternatives the program management Hoogwaterbescherming wants to be able to objectively evaluate the functionality and fundability of the measures.

Therefore Triple Bridge received the task to draw up an inventory of the contemporary costs of the management and maintenance of the flood barriers and works of art. Triple Bridge also issues an advice on the deployment of LCC within the HWBP.

Risk and fragility analysis Brouwersdam


To improve the quality of the water in the Grevelingen a drain in the Brouwersdam is desired. Rijkswaterstaat, the provinces of Zuid-Holland and Zeeland and the municipalities of Goeree-Overflakkee and Schouwen-Duivenland explore hereby the possibility for generating tidal energy. Therefore the Projectbureau Getijdencentrale Brouwersdam has gone through a Joint Fact Finding process with several market players. They have proposed different variations for the tidal energy station.

Nicolien Vrisou van Eck has analysed together with Horvat & Partners the risks of the different variations. Subsequently she translated these risks to a frequency range surrounding the results from the corresponding business cases. With these gained insights the assessments are simplified and clarified.

Fundability subterranean projects


More and more provinces and municipalities formulate a policy for subterranean projects, the Dutch government is also working on the Structuurvisie voor de Ondergrond (STRONG) program. The challenge of the upcoming convenant period is to move from policy plans to concrete projects. Because the subterranean can deliver an important contribution to the solution of societal problems of space, water and energy.

However, the business case including finances in practice frequently proves itself difficult to complete. Commissioned by the Uitvoeringsprogramma (UP) Bodemconvenant Lidwien Besselink and Lex Roukens researched the fundability of subterranean projects.

A2 Maastricht

The A2 freeway near Maastricht will be amended. The freeway will go underground near Maastricht, which will enhance the traffic flow and the quality of life in the city.

The plan is called ‘The Green Carpet’. Its main objective is a stacked tunnel, which will lead 80 per cent of the current traffic underground, while offering a residential area above. There, a green recreational path will be constructed for cyclists and pedestrians, which will connect the Landgoederenzone and the Europaplein junction. The so-called Green Carpet will be given a recognisable and striking city entrance.

Pierre Bermejo of Triple Bridge is involved as a process manager in one of the largest current projects in the Netherlands (approximately € 1 billion). Triple Bridge’s role is primarily aimed at optimising the collaboration between several stakeholders, for example Projectbureau A2 Maastricht (the client); Avenue2 (the contractor); the municipality of Maastricht; and Rijkswaterstaat (the tunnel manager).

Durability criteria for tunnels

The city of the Hague wants the Rotterdamsebaan, a tunnel in the making that connects the highways A4 and A13 and the inner ring road of the Hague, to be the most prominent example of durable infrastructure in the Netherlands.

A team of experts examined the question of what is needed to create a durable tunnel. Chairman prof. Marcel Hertogh presented the examination with nine durability criteria to the city of the Hague on Thursday the 19th of June.

Centrale As Friesland

The province of Friesland is working on a new road between Dokkum and Nijega: de Centrale As. The largest infrastructure project in Friesland to date, it has been divided in 17 shared contracts. Henk Blok, partner of Triple Bridge, is realisation manager of the project in name of the province. In an interview with Cobouw he explains the project.

Left-over steam network

At an industrial and harbour area in the Netherlands multiple companies are in need of steam. Besides that there are companies that can deliver left-over steam from their manufacturing process. By connecting these companies left-over steam can be used effectively and the energy situation becomes more sustainable and optimised.

Triple Bridge was tasked to establish an Energy Services Company (ESCo), that deals with the purchase and transport of left-over steam and through that delivers a blue-print of comparable projects in the future.

Fish migration river

Project office De Nieuwe Afsluitdijk has asked Triple Bridge to give advice on administrative-juridical form of organisation that now and in the future is the most suited to prepare, realise and manage the project fish migration river.

The fish migration river is an artificially constructed, controlled and twisting tidal river, around six kilometres in length. The river has as goal to ease the ecological barrier, that the Afsluitdijk creates for the migration of fish.

The project VMR is one of the innovative projects in the program De Nieuwe Afsluitdijk.

Research regional approach Friesland

Friesland tackles complex infrastructure projects regionally. Triple Bridge has performed an intervision of this approach. The results of the research have been used as basis for a film about the regional approach.

Strukton underground project

In the beginning of 2012 the city of Riyadh, the capital of Saudi-Arabia, wrote a tender for the construction of an underground network. A consortium of companies, among which the Dutch contractor Strukton, submitted a tender for the contract. The start of the construction works began in the third quarter of 2013. By the end of 2013 circa 25 Dutch expats of Strukton were stationed in Saudi-Arabia. The expectation is that in 2014 40 expats of Strukton will be working in the Middle-East country. The project ends in 2018.

Strukton has outsourced the development of the terms of deployment and the earn methodology [?] of Dutch expats to Triple Bridge. The terms of deployment and earn methodology keep in mind the living and working conditions in Saudi-Arabia. Besides that Triple Bridge has recruited several experts of the labor market for Strukton which are now active in Saudi-Arabia.

Amsterdam Climate & Energy Fund

AKEF logo

Amsterdam will invest €45 million in financial and durable profitable energy projects. The city of Amsterdam has established the Amsterdam Climate & Energy Fund for this purpose. On Thursday 4 July 2013 the city of Amsterdam and the e3 signed the agreement that launched the fund.

Raymond van Steenvoorden, managing partner of Triple Bridge and owner of Libertus Energy Finance, will manage the fund together with Michel Hendriks and Jeroen Meinders in name of e3. The investments will be made under conditions in line with the prevailing market. This means that investments must have a minimum goal of 7,5% return of investment. Raymond van Steenvoorden: ‘The fund will mainly invest in projects in the field of energy saving, durable power generation and energy-efficiency. A small amount of the investments goes to innovative companies.

Financing platform for PV projects

For the purpose of Triodos Bank and Libertus Energy Finance a platform has been created that enables financing opportunities for durable energy projects. Through a combination of fiscal and financial structures a financing model is developed for the benefit of durable energy projects. Triodos Bank grants long-term loans for the benefit of these projects through her Triodos Green Fund whilst offering private investors the opportunity to make an alluring return of investment.

Solar Energy

Together with Rooftop Energy and RCA Solar Power an ESCO concept has exclusively been developed. Rooftop Energy, as supplier of durable generated solar energy, takes care of the design and installation of the solar energy station, the financing, the maintenance and inspection, the insurances and the administrative management.

Rooftop Energy delivers the energy to the consumer on the basis of energy produced by the solar energy station. The customer only pays a compensation in line with the prevailing market for the solar energy. Any residual energy is delivered through the main electricity grid.

Financing / funding for the purpose of reorganization and growth

For several companies in the telecommunication sector and the service industry an equity between €500.000 and €2.500.000 has been raised in support of growth strategies and the financing of reorganization.

Interim CFO at an organization quoted at the stock exchange

On a temporary basis interpretation has been given to the role of CFO at a detachment company, that after a ‘reverse’ take-over, reorganization and strategic refocus regained the way to profitable growth.

Advising a company in the healthcare sector

On behalf of an international bank we oversaw and advised by the implementation of a reorganization and financial and operational plan for improvement for the purpose of a medium sized player in the healthcare sector.

Bringing in the financing for the purpose of durable energy projects

For the second round of projects for Rooftop Energy a need for project financing existed. After a market orientation and an intense negotiation session the financing agreement with Triodos has been signed on 30 august 2012. This facility provides Rooftop Energy the opportunity to realise new projects of 3,5 megawatt altogether.

Structuring of PPP projects

In both the United Kingdom and in the Netherlands. In organizational context a professional team has been put together from various discplines with the goal to meet the functional demand specifiations of PPP-concession projects. Meanwhile the team has been involved in a large number of PPP project in the Netherlands.

Restart biomass station

Commissioned by one of the Dutch banks –after a bankruptcy- Triple Bridge has sought new parties willing to co-invest in the restart of the biomass digestion station.

Acquisition and resale of a telecom-infrastructure company

After the bankruptcy of a Dutch stock market listed company a department of the company has been bought up –by means of an active/passive transaction- on behalf of a private client and resold for 51% to American investors. By now the company is active again in the Netherlands and Belgium.

Administrative alliances for the purpose of infrastructural projects

Commissioned by RWS in cooperation with the province and municipalities two administrative alliances have been drawn up for two separate, large infrastructure projects, that have an important relation with development of the region. Triple Bridge wrote the procedure.

Research into and advice regarding cost exceedance of a large infrastructural project

Commissioned by Rijkswaterstaat Triple Bridge did a research on the causes of the exceedance of the cost budget regarding the realization of a large infrastructural project. During a short and intense research time in which all key officials of the project were interviewed, measures for improvement were emphasized to minimalize the risk of recurrence for this kind of complex projects.

Development and implementation of a business concept concerning solar energy

A completely new concept of the generation of renewable energy has been developed by a small team. After an extensive orientation of the available and robust technologies, the mapping of the value chain and the active players and the study of relevant legislation a concept has been developed for the purpose of the marketing of supplier of fully durable generated energy. After the business plan was drawn up and the gathering of investors the plan was implemented.

Rooftop Energy presented the plans on the 29th March 2012. Meanwhile the amount of projects quickly augments and the concept appears to meet the market demand.
