Preface: Cultivating Heijplaat This Management Report is associated with a Masters level architectural thesis project. Such projects exist predominantly as fiction, all-be-it with roots in observations of reality. Cultivating Heijplaat thus attempts to map an understanding of professional practice and construction management in the UK to an imaginary project in the Netherlands. Where possible, points of comparison have been drawn, but for the most part this report assumes the UK culture of construction for the discussion of strategies of building production and the context of professional architectural practice. Nico Prins - the Verhalenman - took occupation of a condemned building in Heijplaat six years ago with the intention of collecting the stories of a place deeply connected with the evolution of Rotterdam as both city and port. Born in nearby Pernis and now living in Kop van Zuid, Nico spends his working days in Heijplaat listening to its stories. In re-telling them, he hopes to ensure that Heijplaat’s stories are given due regard as its future unfolds. Together with the Design Report, this report is a creative and strategic document that relates my encounters with Heijplaat - with Nico as my guide - and serves as a manual with which to frame the development of my project. It imagines how Nico might legitimately initiate the foundation of a community group that procures land and buildings in perpetuity for the community, and how the architectural programme of those buildings can procure the support of a wider group of stakeholders on a regional and national level.

Introduction Cultivating Heijplaat is an investigation into inclusive sustainable regeneration that is sensitive to place. Within that investigation the project considers the design and procurement of a building, or series of buildings. This management report focuses on a two-phase program of design and construction that forms the built element of the Cultivating Heijplaat project. The first phase considers the procurement of a community-house and hostel - named the Verhalenhuis - by a Community Land Trust called Nico’s House. The second phase considers a program of refurbishment of existing dwellings as an alternative to demolition and reconstruction, strategically utilising the facility procured in the first phase. Strong links to education and training are demanded by a multi-headed client group who seek to first test and then expand a model for regeneration-byretrofit, building working knowledge through the application of an area-specific procurement framework. Procurement Objectives WIth the above in mind, Cultivating Heijplaat has the following objectives with regard to procurement: Firstly; to consider the challenges associated with a general ‘skilling up’of built environment professionals to meet the future challenges of carbon-neutral new-build and - particularly retrofitting of existing dwellings to meet new performance standards. Secondly; adopt a permacultural attitude to development of place, accepting multiple outputs as valuable from a system rather than merely the regeneration of built fabric; in particular... Thirdly; to consider how a more inclusive approach to procurement and building might enable learning to run throughout the regeneration of Heijplaat, facilitating opportunities for education and training throughout the design and construction phases and beyond on into the useable life of the building.

Stakeholder Landscape There is a large number of actors and agents already at work in Heijplaat, of which many are already connected in a complex network of interaction. As a place it faces immense change and thus attracts a great deal of attention politically and economically. The diagram to the left illustrates the landscape of stakeholders that could have an influence or role in the Cultivating Heijplaat project. SHIS

The choice of procurement method is therefore a strategic one and for this particular project relationships within it can be exploited - and sometimes engineered - to best fulfil the projects objectives; principally the delivering of social value through education and training as part of the process of procurement. Thus in Cultivating Heijplaat, procurement and the notion of Inclusive Design - defined by the Commission for Architecture and the Built Environment (CABE) as design and development that achieves an ‘inclusive environment’ and creates ‘spaces and buildings that people can use to form strong, vibrant and sustainable communities’ 2 - are closely linked. If meeting the principles of inclusive design requires ‘an understanding of how the building or space will be used and who will use it’ 3, the the ethos of inclusion should certainly be carried across into the process by which such designs are conceived and developed.

Community Land Trust /// A Community Land Trust (CLT) is a non-profit, community-based organisation run by volunteers that develops housing or other assets at permanently affordable levels for long-term community benefit.

used primarily for non-profit organisations that require legal personality. A guarantee company does not usually have a share capital or shareholders, but instead has members who act as guarantors. The guarantors give an undertaking to contribute a nominal amount (typically very small) in the event of the winding up of the company 4.
CLTs range in size, can be rural or urban and provide a variety of housing tenures as well as other community facilities, including workspaces, energy generation, community food and farming. They take a variety of legal forms, although a CLT is usually constituted as an Industrial and Provident Society or Company Limited by Guarantee, and may or may not have charitable status. In UK law CLTs are legally defined in the Housing and Regeneration Act 2008, Section 79 5.

PHASE ONE: The Client - Nico’s House
01 / The Idea - Becoming A Client Fig.H /// Nico and A.N. Architect come up with the idea for an alternative strategy for regenerating Heijplaat, placing greater importance on inclusive governance and decision making. They approach the Stadshavens Projectbureau (as mandate holders for regeneration of the area) and Woonbron (as housing association and landowner) for funding to commission a feasibility study. To facilitate theSHIS transfer of funds they need to be an organisation with a legal identity and thus Nico’s House is formed. A.N. Architect Local Worker

Procuring the Verhalenhuis The first phase considers the procurement of a community-house and hostel - named the Verhalenhuis - by a Community Land Trust (CLT) called Nico’s House. The community-house is intended as a manifestation of Heijplaat’s active community; an expression of existence that affords further engagement with and by others. The hostel is intended as a complementary asset enabling the community to host guests; to work on projects or to conduct their business in the neighbourhood.

This intention requires that Nico and the residents of Heijplaat form an organisational body E that has the capacity to legitimately act as a client on behalf of the wider community. To do E this it needs be able to hold ownership of land in trust for Ethat community. It is also important that the organisation limits the personal liability of its members with regard to any E risk that the organisation is exposed to by its activities.

They have chosen to establish a Private Company Limited by Guarantee in order to given Nicos’s House a legal personality. Along with other nominated residents, Nico and A.N.

The objectives of the CLT enshrine the values behind its creation: principally the provision of a forum for community views on the regeneration of Heijplaat; and the re-imagining of the neighbourhood as a place of education in its widest sense. These objectives would be supported by a more detailed schedule of constitutional articles and amendments that set out the criteria by which the performance of the CLT towards its objectives would be met.

Selecting a Procurement Route - Client Requirements
COMPLEXITY
COST
“ The procurement system should be the most appropriate in the light of the criteria signalled to the architect by the client during and after the briefing stage. In choosing a procurement path, the key criteria are the client’s priorities in respect of: - Time: economy and certainty; - Cost: economy and certainty; - Control: apportionment of risk; - Quality: in design and construction; - Size / Value: small, medium or large; - Complexity: simple or complex.7 ”
Despite having A.N. Architect as a knowledgeable member, Nico’s House are fairly inexperienced as a client. They will therefore require close guidance in procuring the Verhalenhuis.

QUALITY TIME
COMPLEXITY
To demonstrate the viability of an alternative strategy of development in Heijplaat, the Verhalenhuis will need to be high quality in terms of energy performance, which in turn necessitates a high degree of workmanship. The aspiration to provide an exemplary, sustainable community building adds to what is already a challenge in terms of buildability. Although part of a wider area strategy, the Verhalenhuis itself represents a reasonably small and simple building, whilst the unique identity of the area and the clients insight into existing social and environmental value inherent within it require that they retain good control of the project and manage the risk accorded by that control. Due to aspirations for quality, the client is willing to accept slight delays in time to account for acceptable resolution of deisgn challenges, although the fact that the client has obtained funds from other stakeholders necessitates a reasonable level of cost certainty. As a result of analysing the client’s requirements for their project, a traditional procurement route - in which the architect is commissioned by the client to take a brief, develop it, produce designs and construction information, invite tenders, administer the project during the construction period and settle the final account - seems the most appropriate choice, especially given the small scale of the building and particularly when compared to a design and build strategy, where a greater responsibility for design - and therefore greater control in order to manage a greater risk - is passed to a contractor.

The advantage to an inexperienced client such as Nico’s House, working on an exemplary sustainable building with precise requirements, such as the Verhalenhuis is that design input from the contractor(s) can be secured at an earlier stage and usefully inform the development of the design.

WIthin a traditional contract it is possible to choose a two-stage strategy with regard to tendering. In this approach, the project is put out to tender earlier than in a single-stage strategy - typically at the end of RIBA Work Stage C. Tenders are prepared by contractors on the basis of more limited information, and only aim to secure work associated with the development of a design, typically the detailed (D) and technical (E) design stages. The project is again tendered before a contractor is selected to construct the building.

The RIBA Plan of Works The Royal Institute of Brtish Architects (RIBA) publishes an Outline Plan of Work10 . It sets out a series of workstages that have come to be accepted as construction industry standard framework for organising work towards the design and construction of buildings, including the administration of building contracts. These stages run from Stages A and B, representing Appraisal and the preparation of a Design Brief, through to Stages K and L, representing Construction to Practical Completion and Post Completion work such as assisting the client in taking occupation of the building. The Outline Plan of Work details the kind of tasks expected under each workstage, and has recently been updated with a ‘Green Overlay’ which adds a number of sustainability checkpoints designed to encourage an ecological approach to construction. Please refer to Appendix 1 for an illustration of the traditional two stage tendering process, relative to the RIBA Workstages and as applied to the procurement of the Verhalenhuis. The following pages continue to document the procurement process relative to the key on p.6.

Fig.K /// Work Stages A and B are procured by means of a ‘live’ educational experience in partnership with the Akademie von Bouwkunst Project Office. Work associated with development of a brief and with feasibility studies is strategically timed to coincide with the academic year; Stage A commencing in September and running until the Christmas vacation; and Stage B resuming upon return, running until an ‘end of year’ presentation to Woonbron, Stadshavens Projectbureau, Nico’s House and the Concept House Consortium that doubles as an academic assessment procedure. Tactically the Project Office is considering which consultants they might need to develop the project after approval by the funding bodies. Work is conducted by students under the guidance of experienced staff and academics with a background in the built environment professions, and features an emphasis on participatory design and community engagement. Events run as part of this programme simultaneously help to establish the CLT as a known organisation known to the community in Heijplaat. It is likely that more detailed and wide-reaching work will be produced due to the length of time committed to Stages A and B, as well as the greater capacity that a group of students can offer compared to a standard professional office.

Procuring the refurbishment of existing dwellings Following the successful completion of Phase One, the Stadshavens Projectbureau and Woonbron consider the wider implications of an alternative regeneration strategy for Heijplaat. There is still much to be tested, principally the refurbishment of existing buildings. ‘Retrofitting’ is a relatively undeveloped field of knowledge, but one with immediate and widereaching future applications given the large number of existing properties that contribute to energy and emissions targets across Europe. Therefore, it will be of benefit to client, design team and contractor to develop methods, techniques and working relationships that might allow them to tackle such a challenge effectively.

With Nico’s House taking the lead, a development company is formed in order to develop Phase Two. Woonbron provide some funding as an interested party, standing to benefit from the success of the project in their position as a land owner in the wider area. The Projectbureau lend political support bringing contacts, whilst the Concept House Consortium - connected to Woonbron by funding streams and the Projectbureau by permission - put up the majority of the money, seeking to develop retrofit alongside their exemplary new-build program. The Stichting Hervormde Internaten voor Schippersjeugd (SHIS) will eventually rent dwellings in the finished scheme and so enter at this point as an interested party, providing some funding in partnership with their long-term collaborators and educational provider Prokino. Thus the principal objective for Phase Two is the development and retention of knowledge associated with retrofit and refurbishment of a particular type of housing stock in a particular area, coupled with the provision of opportunities for education and training and an inclusive procurement process.

(Why Not) Self-Build? An initial assumption was that the project objectives might be best facilitated by procuring scheme as a community self-build project, with eventual tenants providing labour for all or part of the work, However, this was dismissed due to the limited scope for technicallydemanding deign solutions as may be necessitated by high performance refurbishment; and also due to the relative specificity of procurement strategy. An interview with Robin Hillier of Architype provided a scope of the contractual ambiguity of many self-build schemes11.

Fig.O /// Soundings /// Soundings form part of the evolving design methodology used in Cultivating Heijplaat and involve a number of methods for accumulating indirect knowledge as part of a strategy for approaching a site remote from the designer and dependent upon the reconciliation of fictional narrative with observations of reality.
(Why Not) Partnering? Partnering is a fashionable yet relatively undeveloped form of procurement by which parties interested in developing a working method, body of knowledge and relationship with regard to a specific - and often experimental - kind of project enter into a trust-based, transparent agreement in which risk is shared equally between all parties.
CHAPPEL, D. and WILLIS, A. (2010) The Architect In Practice (10th Edition) Oxford: Wiley-Blackwell University, p.182. 12
However, partnering is still vaguely defined and open to abuse; anecdotal evidence reports employers and contractors using the cover of partnering to disguise business as usual12. It is based largely on trust and does not translate easily into a legally-binding contractual relationship. As such, partnering agreements usually exist alongside other standard forms of procurement as a means of aligning the ethos of parties involved. (Why) Frameworks Frameworks are a more widely-tested means of establishing a pool of skilled, knowledgeable consultants and contractors from which to select when undertaking a series of contracts of a similar nature:

As an architect at sustainable-building and Passivhaus-specialist Architype, Robin Hillier has over 15 years experience designing environmentally friendly buildings in a community self build context. As project architect for the Diggers self build scheme he became convinced that simplicity, both of the building form, and the construction process, were crucial for a truly low environmental impact. The project won a RIBA design award. Robin was project architect for several other group self build schemes, including the Hedgehog Housing Co-op - as featured on Grand Designs. I interviewed Robin - by telephone - to draw on his experience of community self-build with particular regard to procurement strategies.

Handbook - The Law For Architects (9th Edition) London: Architectural Press, p.174.
“The framework agreement sets out the principal terms and conditions and then the client can simply call off each project without the need to re-tender…There is usually no guarantee as to the volume of work, nor an obligation to tender any work whatsoever…As well as reducing tendering costs, the purpose of framework agreements is to encourage construction teams to stay together from project to project, making the most of what they have learned from working together on a number of similar projects13.”
Any one of the parties included in the Heijplaat Development Company may develop a retrofit project in the future; most likely Woonbron as landowner, with one or all of the others as funders. The framework agreement approach typically promotes ‘partnering’ by ‘including provisions designed to encourage parties to work together in a manner requiring open-ness and a spirit of mutual trust and respect’ (p.174). A framework agreement administered by the development company might include provisions such as: a preference for retaining existing buildings and refurbishing them rather than demolition; a requirement to prefer other consultants or contractors on the framework where possible; and the utilisation of a certain proportion of apprentice labour, providing opportunities for training to young people from the local community.

Within the Framework Agreement, a Design and Build contract is used, encouraging contractors to take responsibility for design, and apportiuoning risk away from the client for a larger project. This also encourages other consultants to be invited onto the framework as employees of the contractor, bringing new ideas and broadening the knowledge base accumulating within the framework.

Although these facilitie were inherently ‘extra’- procured on a temporary basis and independent of existing buildings - it is anticipated that the best way of utilising School Parasites’ expertise in dsign and installation of educational spaces would be to employ them diectly and to ask them to do portions of the work.

As client, the Heijplaat Development Company employs the Akademie von Bouwkunst Project Office as a consultant from the Framework. They are retained as client advisor following the letting of the building contract. The contractor - also selected from the framework - employs their own architect and other consultants, providing an opportunity for new ideas and expertise to join the framework. The contractor’s design team develops the design from Stage D onwards, whilst the Project Office participates in Stage L. Another project review is conducted as soon as practically possible in order to reflect on the success of the refurbishment and share lessons learned. At this point, the client can decide whether to proceed with the methodology of regeneration and apply it to other blocks in Heijplaat. In future projects it is anticipated that certain work stages can be compressed in terms of time and cost, benefitting from the learning captured by the Framework Agreement. Stage L3 is conducted at a later date, once sufficient time has passed for meaningful data and observations to be collected concerning the performance of the buildings in relation to the requirements of both client and users.

COSTING: Capital Construction and Whole Life Costing Estimating the cost of building produces information valuable to all members of the design team, client and contractor groups; even in the very earliest stages of a project. Estimates are usually arrived at by considering the cost of precedent buildings of similar type and size. In the UK, this can be done using a cost index such as the Building Cost Information Service (BCIS)15, or reference library of projects and cost data such as the Architect’s Journal Buildings Library16. The latter is particularly useful as it gives information on design intent and procurement method in addition to project cost related to Gross Internal Floor Area (GIFA). Cost indexes however are valuable proven tools for adjusting costs for changes over time and, in combination with appropriate location factors, can facilitate development of conceptual estimates useful in the procurement of buildings.

AJBL02 Retrofit for Living /// London, UK (2011)
Use: Hostel / Guesthouse for Arts Organisation Purpose: Accomodation / Reseach Facility Size: (GIFA) 438m2 Cost: £910,000 (£2,077.00 ) / m2) Adjusted to 2014: £2,221 / m2
Use: Residential Purpose: Retrofit a two-storey terraced house, with a target 80 per cent reduction in CO2 emissions, as part of the Retrofit for the Future program. Size: (GIFA) 99m2 Cost: £72,570 (£733.00 ) / m2) Adjusted to 2014: £755.00 / m2
Client /// Grizedale Arts Architect /// Sutherland Hussey Architects
Reasons for selection: Similar use - Accomodation for guests of the organisation who might be working on ‘projects’ with the organisation, site offices, and conference facility / Includes enabling work to use gardens for projects and food production and preparation / Client has similar aspirations in terms of quality of finish / Size.
Location Factors - Working in the Netherlands
Client /// East Thames Group Architect /// Penoyre & Prasad
Reasons for selection: Retrofit and Refurbishment for family residential purpose. Discrepencies: UK location / Original building is much newer (1992) / Only for families, not supported livingin flats.
Discrepencies: UK location / Use of listed building may have added to the cost / Refurbishment not new build.
Another key adjustment to consider is the location of the project. A location factor is an instantaneous, overall, total cost factor for converting a base project cost from one geographic location to another. This factor recognizes differences in productivity and costs for labour, engineered equipment, bulk materials, commodities, freight, duty, taxes and project administration, but does not include the cost of land, scope/design differences for local regulations and codes and differences in operating philosophies17.
AJBL03 Idea Store /// Whitechapel, London, UK (2004) Client /// London Borough of Tower Hamlets Architect /// Adjaye Associates
Use: Library / Community Use Purpose: Continuing Education Facility Size: (GIFA) 5000m2 Cost: £2,100,000 (£420.00 / m2) Adjusted to 2014: £450.00 / m2
I am producing cost estimates using a UK-based cost index and precedent projects based in the UK and so a conversion factor for the Netherlands would be useful in this particular project. However, I have found that due to the limitations listed above, this data is particularly volatile and closely guarded by firms offering international cost estimating consultancy18. Therefore, I have assumed the UK location factor for London, assuming that working in Rotterdam may be subject to similar conditions, and selected the London Borough of Greenwich due to its similar location relative to city and river estuary. If I were to be engaging with this project as a UK-based architect, it may be useful to consider working with a Rotterdam-based architect or quantity surveyor for this initial estimate, as proposed in the fiction that is Cultivating Heijplaat.
Architect’s Journal Buildings Library /// Precedents as basis for cost estimates Cost estimates are just that. Estimates. Much can be drawn from precedent construction projects to allow an informed estimate to be made. The projects shown on this page have been selected from the Architect’s Journal Buildings Library for their relative comparison to the procurement of the Verhalenhuis and associated refurbished accomodation.
Reasons for selection: New Build / Community Use / Urban Location / Municipal Client / Wider reaching educationl purpose Discrepencies: Cost seems very low / No residential element.

Phase One - The Verhalenhuis Fig.R/// Phase One is characterised by: -
-
Demolition of existing buildings. New build construction on a cleared site. The procurement of general ‘community centre’ facilities, such as classroom teaching space, activity room relating to gardening secure storage, teaching kitchen, eatery, foyer exhibition space and offices for short-term working (studio-style) and administration. The procurement of complementary hostelstyle accommodation. A relatively large proportion of external works.
Fig.S /// Phase Two is characterised by: -
Procurement of two types of residential accommodation. Refurbishment of buildings. High specification with regard to performance and quality of finish. Contracting that assumes high use of apprentice labour.
-
Cost estimates for the Verhalenhuis are based on the BCIS index entry for newly constructed community centre from BCIS. However, this does not take into account the short-term accommodation aspect of the project. From the AJ Building’s Library, Grizedale Arts’ Lawson House in Cumbria (ref: AJBL01 opposite) most closely matches the project programmatically, but is based essentially on refurbishment of an existing building. It is therefore perhaps more appropriate to use the cost/m2 value from Lawson House to represent the cost estimate, taking into consideration the similarity of the client’s aspirations to those of the Verhalenhuis with regard to combination of program and quality of finish. Phase One also includes demolition works - estimated separately - and a higher than average percentage addition attributed to External Works. This latter element is due to the provision of a large area of public realm roughly equal to the footprint of the building and the likelihood of contaminated ground due to the sites proximity to land used formerly for shipbuilding and other port-related activity. Phase Two - Refurbished Residential Accommodation Phase Two involves the conversion of existing buildings into two types of residential accommodation: flats for young people living independently; and family maisonettes. In each case, the upper quartile estimate has been used due to the client’s aspiration to procure an exemplary building with regard to performance and quality. Conversion of existing buildings also necessitates a higher than average percentage addition for contingency. This is due to the likelihood of running into difficulty with the existing buildings during refurbishment, and the educational role of the contractor in providing training on the job. Four buildings will be refurbished:

It is worth noting that this is higher than the figure usually expected, which ranges between 10% and 20% depending upon reference source. This can be attributed to the high cost/ m2 used in estimation to represent aspirations for high quality in specification and workmanship
Whilst investment in low-energy design and robustness will clearly benefit the operators of the Verhalenhuis through reduced operational costs, the refurbished residential accommodation procured in phase two can also benefit from consideration of whole life cycle costs in the design stage. In this case, savings in 40% utilities bills can be passed on to the residents themselves who will be renting the property from the client. Alternatively, the client could benefit directly from the savings made by including utilities within their rents, improving the perceived offer to tenants. In the specific case of building in Heijplaat, low - or even zero net energy use as a design feature may help to attract funding or secure grants from regional development bodies such as the Stadshavens Rotterdam Projectbureau who are promoting innovative sustainable design.

INCLUSIVE DESIGN & SOCIAL VALUE Inclusive Design, and aspirations to cultivate opportunities for education and training as part of the procurement process have the potential to generate added value for clients and society as a whole, particularly as pat of a longer term strategy for regeneration. The concept of ‘social value’ is used to discuss the kind of value that can be difficult to measure using standard methods of evaluation. One method is to simply equate social value to more widely understood terms associated with the evaluation of potential financial returns on investment. Social Return on Investment (SROI) is an analytic tool for measuring and accounting for a much broader concept of value, incorporating social, environmental and economic costs and benefits into decision making, providing a fuller picture of how value is created or destroyed. It is based on the premise that ‘conventional cost-benefit analysis does not capture what really matters to us’ and that ‘there are many things which we value, as societies and individuals, which cannot be easily captured in economic terms’ 19. SROI is able to assign a monetary figure to social and environmental value which is created. For example, research by the New Economics Foundation (NEF) on the value created by a training programme for ex-offenders revealed that for every £1 invested, £10.50 of social value was created in terms of savings made in benefit payments and other related costs to society of leaving ex-offenders untrained, including the apportioned cost of policing. Arie Voorburg of sustainability consultants ARCADIS are working with the Stadshavens Projectbureau to establish social value streams in Heijplaat. By demonstrating the future benefits of a home-grown, skilled labour-force to businesses and the municipality - and evaluating it in Euros - ARCADIS hope to encourage corporate and municipal investment now in acknowledgement of the long term economic benefit 20. In particular, Rotterdam and its Port are largely dependent upon an immigrant, transient labour force. Economically, this means that money - paid out in wages - can leave the country, with workers often only staying a few years before moving on, or sending money home to families. Training opportunities for - and motivation of - a home-grown labour force has a clear future economic benefit to employers and the municipality A similar strategy can be applied to evaluating the benefit of providing community facilities and ‘extra schools’ that support the idea of educational opportunities occurring in the

Arie Voorburg /// ARCADIS Arie Voorburg is a consultant at ARCADIS, an international company based in Rotterdam - providing consultancy, design, engineering and management services in the fields of infrastructure, water, environment and buildings. ARCADIS are working with Stadshavens Rotterdam to develop ‘value streams’ in a system of ‘socio-ecological urbanism’ for the Stadhsavens area as a whole. Heijplaat is viewed as a test ground for creating value streams based on education that tie in closely with the development at RDM.
VOORBURG, A. (2012) Conversation with the author. [Interview] Conducted in person at 20
ARCADIS’s offices in Rotterdam, 07/02/2012.
I interviewed Arie to understand more about ‘value streams’ that connect to education, particularly the concept of ‘community schools’ and opportunities for lifelong learning applied to Heijplaat. Ensuring that an indigenous population has the skill and motivation to enter into Port-related industry and jobs - particularly low and mid-skilled logistics-related occupations - is a key element of Stadshavens economic sustainability agenda, aiming to reduce relience to short-term transient workforce of immigrants.whose migrant economic status weakens Rotterdam’s city economy.
neighbourhood as a whole at multiple levels. Future ongoing costs to the municipality - such as the payment of social security benefits - could be offset by investing in education and training now. Evaluating this figure in financial terms - a language understood by the municipality can encourage investment. Whilst social value is difficult to evaluate, it is often best understood through anecdotal evidence. Stories again play a role and can be used to approach funders who attach importance to the public relations value of such initiatives; a good story can be invaluable in promotion and marketing. Thus the Verhalenhuis offers a mechanism by which to collect evidence of the generation of social value, in its role as a ‘community house’.

Construction Design & Management (CDM) regulations automatically apply to the UK construction industry and doubtless have an equivalent in the Netherlands. The current UK regulations were published in 2007 and serve the purpose of improving the notoriously poor health and safety record on construction sites by requiring all parties involved in a construction project to take responsibility for health and safety standards 21. They place legal duties on virtually everyone involved in construction work 22. “Those who could create health and safety risks have been made responsible for considering and controlling them during all stages of the project – conception, design, planning, construction work, future maintenance and use of the building, including demolition 23.”
The regulations set out certain appointments that must be made in a building contract alongside responsibilities for clients, designers and contractors, as well as the requirement to appoint a CDM Co-ordinator for ‘notifiable works’. As a project certainly lasting ‘more than 30 days or [involving] 500 person days of construction work’, both phases of Constructing Heijplaat are notifiable and require the appointment of a CDM Co-ordinator as ‘a competent person or body with the overall responsibility for co-ordinating health and safety aspects of the design and planning stage and advising the client on all health and safety matters’ 24. It is inadvisable for designers to start work beyond initial design unless a CDM Co-ordinator has been appointed 25. Architects - as designers of elements to be constructed - have the opportunity and therefore responsibility to design out any unnecessary risks anticipated during the construction and eventual de-construction of the building, including those that may affect occupational health arising from the use of hazardous materials. If considered
strategically, CDM can be used to add value to the procurement method, particularly with regard to training. There are a number of CDM and Health & Safety issues associated with procurement of buildings in Cultivating Heijplaat; most notably those that relate, firstly, to the intention to use apprentice labour wherever possible; and secondly, to the observation that sections of Phase Two will be under development whilst other sections, as well as and the whole of Phase One will already be occupied. The first condition can be addressed by ensuring that contractors deliver comprehensive ‘toolbox talks’ on safe working methods and emphasize the importance of CDM and Health & Safety in their role as trainers. Over-running the building schedule - and particularly in the case of Design & Build in Phase Two, extensions of time - should be permitted in preference to undue pressure to complete being placed on contractors, in acknowledgement of the training objective of the procurement strategy. The second condition is harder to address, although ‘no weekend working’ can limit disturbance to occupants of the residential elements of the scheme and is not an unusual tactic. Adequate and robust hoarding should be used to separate areas under development from those that are in use - particularly any demolition workwith those areas being clearly communicated to local residents. Interestingly, CDM regulations do not apply to project designed in Britain but intended for construction abroad 25.
