Given that
about 75% of the EU building stock is considered energy inefficient and the
energy use in buildings (residential and commercial) is responsible for about
40% of final energy consumption in the European Union [1], energy efficiency
renovation represents a promising long-term growth possibility for the EU
construction sector. Nevertheless, construction industry is seen as being
relatively inefficient in both process and service delivery. There is evident
gap between the designed level of energy efficiency and the level of energy
efficiency realized [2] also due to a lack of built quality and skills gap. The
construction sector suffers from a lack of skilled workers in general, while
energy efficiency renovations even requires additional competences and
qualifications. According to the World Economic Forum, construction labor productivity
has stagnated over the past 50 years [3].
This shows
that nearly Zero Energy Building (nZEB) construction
and renovation need an enhanced systematic approach for the quality control of
the entire process. An enhanced quality control approach can only be achieved
by a fully qualified and equipped workforce, capable to implement, execute and
perform all the necessary actions with a full understanding of the
responsibility of their own profession and actions, as well as the relation
with the other involved professions and actions within the value chain.
With
objectives to improve knowledge, skills and competences of all the relevant
disciplines involved in nZEB construction and
renovation, and create more collaboration between them, the BIMplement
project was funded. The BIMplement is a 30 month-long
EU funded project involving 10 partners from 5 different countries:
France, the Netherlands, Lithuania, Spain and Poland which started in September
2017.
One of the
first projects contracted under H2020 Construction Skills was PROF/TRAC: ‘Professional
multi-disciplinary Training and Continuing development in skills for nZEB principles’ (2015–2018), www.proftrac.eu
which is also the foundation for BIMplement. REHVA
was one of the core partners in this project; moreover, four national REHVA
members were involved in PROF/TRAC as national training providers (ATECYR,
DANVAK, HKIS, TVVL).
The overall
objective of PROF/TRAC was to develop a European training and qualification
scheme as part of a life-long learning process for continuous development and
up-skilling of professionals, aiming at middle and senior professionals with a
higher education degree (white-collars). The collaboration in PROF/TRAC with
European organizations like REHVA, Architect Council of Europe and Housing
Europe turned out to be an important prerequisite for the implementation of the
results as it appeared to be very effective both for endorsement and for a
further European roll out as their national members can act as training
providers.
BIMplement
builds upon the PROF-TRAC project as also several BuildUp
Skills projects (FR, NL, LT) where these project’s results and successes offer
the necessary building blocks in training, CPD, methodologies for skills
mapping (http://proftrac.eu/training-materials.html;)
for all professions and for levels involved in nZEB
skills.
BIMplement
engages further and tackles remaining challenge on how to make a major step
forward in the implementation of these qualifications where BIM can offer the competitive
advantage as an efficient management strategic tool and as such, gives an opportunity
to implement results in a BIM-enabled workplace learning environment. This is done
in a cross-cutting process that is:
· Cross-trade: with a multidisciplinary approach throughout the entire value chain of the buildings sector.
· Cross-European Qualification Framework (EQF) -level: addressing both blue-collar workers, middle and senior level professionals.
· Cross-time: by setting up a flexible qualification methodology so that new innovations and uses of technologies can be addressed.
· Cross-country: by setting up a mutual recognition scheme of qualifications among different Member States, but by leaving room for Member States specific roles and uses of technology
· Cross-value: by improved appreciation of the end user's needs including the quality of indoor environment (thermal and visual comfort, acoustics, air quality, etc.), in an improved operation and maintenance by closing the learning loop using BIM as information carrier.
· Cross-size: from SME to Enterprise, based on regional of local experience centres or BIM-Hubs.
· Cross-project: by using BIM as a learning environment, to facilitate and enable the learning flow.
In this way BIMplement paves a road towards an improved
quality for nZEB construction and renovation by the
following objectives:
·
addressing
the entire value chain of the building sector and the total construction
process (from pre-design to in use phase);
·
improving
skills of professionals as blue-collar workers for nZEB
quality (cross-trade & cross-level) via large scale trainings and
continuous professional development (CPD);
·
developing
a flexible qualification methodology that is able to anticipate new products
and processes (cross-time) in different countries (cross-country);
·
empowered
by BIM and BIM enhanced workplace learning tools.
Figure 1.
The BIMplement methodology aims to close the gap between the knowledge in
practice and knowledge in paper by creating various learning and knowledge
exchange loops, supported by adequate quality control.
The four BIMplement steps present a journey towards the upgrade of
the quality of the work needed to meet nZEB targets.
The project
started with the development of a flexible qualification methodology to
standardize the needed qualifications and a range of learning tools, to unlock
and implement these qualifications. By using a systematic standardized
approach, the mapped qualifications are to be transparent and comparable
between EU member states, thus facilitating and providing EU mobility; robust
and flexible (dynamic) approach for national adaptation. Also, as the evolution
of technologies and materials is rapid, the methodology requires continuously
reconsidering and updating our knowledge and skills.
BIMplement
develops a general BIM-enhanced qualification framework (QF) structure and
method to identify the different professions and professional levels for the
specific crucial topics for nZEB technologies,
concepts, products, as a function of the phases in the construction process. It
is adaptable for blue and white collar-workers and professionals, with an
implementation within existing learning tools and methodologies. This is based
on PROF/TRAC Qualification scheme framework while utilizing BIM to connect the
knowledge sources with the building process, building components and building
products. The methodology building upon existing BIM process structures (CEN/TC 442
Building Information Modelling (BIM)) and existing classifications (e.g. IEC 81346
and ISO TC 59/SC 13/WG 11: ISO 16757 Data structures
for building services product catalogues) where the BIMplement
didactical task descriptions for the addressed technologies and components are
then linked with suitable education material and trainings on a national level.
To keep
focus within the project itself, the testing of the methodology is dedicated to
the implementation of ventilation
systems and ensuring the air-tightness
of buildings. As for the ventilation, there can be a didactical task
connected with the BIM object or technology. Nevertheless, air-tightness is a
more complex building application area as it is related to almost all the
different building envelope components (transparent as opaque) as to joints
application in-between. Therefore, air tightness should be assessed more
holistically with objective to control air leakage and heat losses through the
building fabric and at interfaces, joints & junctions.
The objective of the BIMplement is to apply the methodology in 50 experimental sites (in NL, PL, LT, SP, FR) leading to upskilling 200 white collars and 1000 blue collars in 30–35 construction and renovation projects in France, and others each executing about 5 projects. The learning methods and the qualification schemes are connected to the projects defined in the pilot field labs and the experimental sites, this in order to improve the quality of the involved white- and blue-collar workers and thus, improving the overall quality of the construction process.
The
methodology is implemented in collaboration with BIM-learning centres or national BIM experts where several objectives
are to be achieved as presented in Figure 2.
Figure 2. Implementation strategy of the
BIMplement methodology in ‘real’ construction projects.
First BIMplement
trainings already took place in France. Read about the feedbacks from the BIMplement implementation sites:In France, the one-day BIMplement training took place on the construction site
of an office building at Saint-Nicolas-lez-Arras
attended by 16 managers and white-collar workers from 14 companies involved
in the works; 3 representatives from the client (KIC, a private office
builder) and from the third party responsible for building control
inspections; 1 BIMplement coach and 1 future ‘BIMplement master trainer’. The comments of the
participants confirm the interest of this training, as show these witnesses: ·
Client’s
employees, KIC, had to convince the enterprises to come to the training where
they expressed at first several concerns: ‘I was quite afraid before, because I was not sure that the companies
would come to this training session. Most of them were reluctant, saying that
they did not understand the interest of a training on BIM and related issues
(airtightness and ventilation). But all of them came, and all of them were
very satisfied with the training. We (KIC) plan not only to continue the
BIMplement training at our Saint-Nicolas-lez-Arrassite,
but also to use BIMplement at the construction site of a 4.500 m² office
building in Valenciennes (nearby Lille) next year’. ·
From
managers and white-collar workers following feedbacks were received: ‘A very interesting training. I know now why and how the BIM model makes
possible the positive interactions between the crafts…’ ‘I discover that BIM is a beautiful tool to do a high-quality work… ‘ ‘When you have high energy efficiency goals, BIM is of great help…’ ‘I now see that BIM is the medium to solve the conflicts between the
crafts at the workplace…’ Figure 3. First BIMplement training taking place in
France, 2018. |

In the end
project’s aims to ensure that more Member States and nZEB
areas will benefit, while fostering further cross-border cross-sector
developments on a lasting basis. The lessons learned from the ‘pilot field labs‘ and the ‘experimental sites’ will be capitalized,
together with the tools and learning methods developed. To this effect, last
phase of the project covers further exploitation and replication of the project
results to increase the number of skilled building professionals and craftsmen
across the building value chain through spillover effect. The projects replication and exploitation
strategy aims at deliberate efforts to increase the
impact of successfully tested innovative qualification and training schemes.
After the
mapping of existing knowledge sources was done on a national level, it seems
there is sufficient knowledge to deliver quality. However, the problem is that
the availability just on time and fit for purpose is very poor. As tested in BIMplement, utilizing BIM allows storing relevant learning
and process metadata in an efficient way. Secondly, BIM can be enriched with quality
levels, needed skills and linked trainings. In this way, BIM can serve as a
multidisciplinary data repository. Enhancing or connecting BIM models with
didactical information can enable and facilitate the learning process over the
whole value chain. Thirdly, BIM can improve a collaboration between different
disciplines and management of works allowing synchronization of design and
construction phase. In the end, in BIMplement BIM on its own is not the goal but improved
quality for nZEB construction and renovation and a
more efficient systematic process are the goals. At the moment the best
approach to reach these goals seems to be using BIM.
To
conclude, the construction sector is one of the main pillars of the EU economy
where the construction industry is one of the largest European industries with
9% of the GDP of the EU [4] and 18 million jobs and 3.1 million enterprises [5].
Innovative solutions within digitalization of the construction industry such as
BIM, can respond to the sector’s challenges as are lack of skilled workforce,
energy efficiency and lagging productivity. On this matter, energy efficiency cannot
be reached without sufficient quality and no quality without qualified
workforce. As the practice shows, to obtain sufficient qualified workforce
upskilling and trainings are required and this is where BIMplement
comes in play.
