WS-11: BUILT AS DESIGNED

The 2-hour ““BUILT AS DESIGNED workshop:New Technol-ogies for Self-Inspection and Quality Checks on the Construc-tion Site”workshop addressed the differences and complementa-rities of the respective approaches of ACCEPT, BUILT2SPEC, and INSITER, from the ex-pected exploitation point of view.

INSITER: Intuitive self-inspection techniques using augmented reality for energy-efficient buildings made of prefabricated components [www.insiter-project.eu]


The workshop had 3 phases:
1. a quick presentation of each project (main objectives, consortium, development activities),
2. then a presentation of the main expected exploitable results (type of results, main innova-tion, description of the market),
3. and finally an open discussion between the projects representatives and the public about the contexts of application and the complementarity of the presented exploitable results.
Outcomes: Discussion on the best opportunities for the exploitable results of the 3 pro-jects, who will propose new technological solutions to be applied for the self-inspection of con-struction processes.

Over the last years, most of the research and development efforts in terms of ener-gy and environmental efficiency of buildings concerned design support technolo-gies, construction products, or exploitation tools. ACCEPT, BUILT2SPEC, INSIT-ER tackle the construction process itself and how we can improve the performance by ensuring that the building “as built” fits with the building “as designed”. Funded simultaneously in the same technical and economic context, these projects pro-pose three original approaches, making the most of connected tools and innova-tive ICTs, which may present several complementarities.


ACCEPT, BUILT2SPEC and INSITER are three H2020 projects started in 2015, and funded from the topic “EeB-03-2014: Development of new self-inspection tech-niques and quality check methodologies for efficient construction processes”. All three projects originated from the statement that con-structed buildings generally do not perform in agreement with what their design stage allowed to expect. Each of these projects aims at providing a technological an-swer for self-inspection and quality check improvements to reduce the gap between the planned performance and the actual one.



ACCEPT Project Introduction

The better energy-efficient building components of today have one major flaw: The loss of efficiency through improper usage during the building process can be dramatic. ACCEPT will ensure the proper usage of the components during the building process with the help of Smart Glasses (Optical Head Mounted Displays, e.g. Google Glass or Epson Moverio ).
The Smart Glasses will unobtrusively provide the workers on site with guidelines ex-actly when needed, while common methodologies – defined by the site manager – for all workers can be incorporated to standardize and coordinate the overall working ac-tivities. The execution details brought to the construction site by ACCEPT can be cus-tomized for the working site, the building components and the different contractors to even bridge language barriers with ease. In this way it is possible not only to minimize the loss of efficiency due to thermal bridges or bad air-tightness, but also to increase the overall efficiency, reliability and productivity of the construction processes.

Knowledge transfer


Providing guidelines and methodologies during the construc-tion process by transferring knowledge between the different stakeholders of the construction process


Project Coordination
Increasing the efficiency, reliability and productivity of a con-struction processes by providing workflows for the interaction between different entities on a construction site.


Quality Assurance
Improving the final thermal, acoustic and energy performance of buildings by providing sophisticated quality assurance tools, which will be used actively or passively by different stakehold-ers during the construction process and provide self-inspection capabilities.


ACCEPT Outcomes

Relevant data will be aggregated passively on the construction site by workers wearing Smart Glasses as well as actively using different sensors accessed through a Smartphone operated by the site manager. In addition, visual annotations can be attached to objects in order to exchange context-based information between workers; bringing the Wiki idea to the construction site. The data is processed in a cloud environment with self-inspection methods to determine important characteristics (such as U-values) as well as to monitor the coordinated progress of different par-ties cooperating in the building process. Thereby a sophisticated tool for the quality control dur-ing the building process is provided which guarantees that the energy performance at commis-sioning stage will meet the one expected at design stage. ACCEPT will reach the following key ob-jectives:

 Improving the final thermal, acoustic and energy performance of buildings by providing so-phisticated quality assurance tools, which will be used actively or passively by different stakehold-ers during the construction process
 Reducing the mismatch of energy performance between design and commissioning stage by providing guidelines to apply the sophisticated quality assurance tools mentioned before
 Providing guidelines and methodologies during the construction process by transferring knowledge between the different stakeholders of the construction process
Increasing the efficiency, reliability and productivity of a construction processes

From a user perspective ACCEPT is focused on the fol-lowing very clear main results:
1. The Construction Operator Assistant App (CoOpApp) running on Smart Glasses, which passively collects data and actively provides guidance to the worker on site during the building process. (Pillar I: Ad-vanced Knowledge Transfer for Energy-efficient Con-struction)
2. A Site Manager App (SiMaApp) running on a mobile device, which allows to remotely coordinate the work-ing process as well as collect additional data on site by different sensors. (Pillar II: Agile Project Coordination for Bridging Heterogeneity)
3. An interactive web-based Dashboard as a monitor-ing and quality assurance solution. The Dashboard will use self-inspection methods to determine important characteristics such as U-Values. (Pillar III: Adaptive Quality Assurance with Self-Inspection Features)

Built2Spec

Meeting EU energy efficiency targets for both new builds and retrofits will be much easier to manage in the near future thanks to the development of new and innovative on-site quality assurance tools. In order to achieve this ambitious objective, the Built2Spec project will deliver a new set of breakthrough technological advances such as:


 3D and Imagery Tools
 Building Information Modeling (BIM)
 Smart Building Components
 Energy Efficiency Quality Checks
 Indoor Air Quality Tools
 Airtightness Test Tools with air-pulse checks
 Thermal Imaging Tools
 Acoustic Tools


We begin with users and their requirements to set a common baseline across our pro-ject team. Our research and technological development activities interact with our pilot testings. In a second step, we will integrate the framework, technology and knowledge developments into the Virtual Construction Management Platform. We then run exten-sive and long duration pilot activities and deliberate pilot planning, assessment and management. We separate exploitation and training from communication and dissemi-nation to allocate appropriate resources and leadership to each.

TB2S tools

 Quality Checks – Built2Spec will compile and further develop the know-how of various experts within and outside the consortium to achieve an easily usable expert tool and to guarantee high quality construction work.

 Indoor Air Quality Tool – Built2Spec will optimize the first analyzer dedicated to real-time measurement of indoor air quality by developing a truly portable version, designed and adapted for field operation.

 Thermal Imaging Tool – In the construction sector, the measurements from TIR devices are exploited in a mostly qualitative way. Built2Spec will propose methods to allow quantified assessment of thermal properties of buildings.

 Smart Building Components – Built2Spec will implement the novel use of embedded sensors in precast elements in order to continuously monitor both the thermal and structural performance of the building.

 Building Information Modelling – Built2Spec will use the information in BIM to check whether the as-built situation complies with the design – not just after the project is delivered, but also during the construction process.

 Airtightness Test Tools – A new device enables quick checks (<1min) by generating and analysing a low pressure pulse from an autonomous unit which does not penetrate the building envelope. A robust unit for construction sites, is being developed.

 Acoustic Tools – Built2Spec will develop a novel lightweight sound source for acoustic testing that provides a more diffuse field than standard loudspeakers and ensures easy portability and regulation compliance.

 3D and Imagery Tools – 3D reconstruction aims to capture real objects. This process can be accomplished either by active or passive methods. The combination of these methods can be used to reconstruct a large variety of scenes in 3D!

 Virtual Construction Management Platform – All tools will be connected to a Virtual Construction Management Platform supporting the collection and sharing of all project data, from initial design to delivery.

INSITER: “Intuitive self-inspection techniques using augmented reality for energy-efficient buildings made of pre-fabricated components” [www.insiter-project.eu]


Project Introduction
Energy-efficient buildings (EeB) have become a priority of the European Commission (EC) to promote and maintain sustainability in the con-struction sector. Within the recently launched EU research programme “Horizon 2020” (http://ec.europa.eu/programmes/horizon2020/), a particular attention is given to quality-gap and performance-loss between de-sign and realization both in new construction as well as refurbishment of EeB. The construc-tion sector is characterised by a segmented approach involving a variety of skills and ex-pertise with different roles and responsibilities. During construction, each actor of the con-struction value-chain must ensure that his con-tribution fits into a quality framework defined collectively at the design level.
The critical mass of EeB in Europe by 2020 will be achieved through sustainable industrial-isation of high-performance architectural, structural and building-service components. However, realising the targeted performance in design is hampered by critical shortcomings during on-site construction and refurbishment that cause a lower built-quality and sub-optimal energy-saving in the building lifecycle. Through new self-inspection techniques,



INSITER will fully leverage the energy-efficiency potentials of buildings based on pre-fab components, from design to construction, refurbishment and maintenance. It will scale-up the use of BIM for standardised inspection and commissioning protocols, involving all ac-tors in the value-chain. The key innovation of INSITER is the intuitive and cost-effective Augmented Reality (AR) for self-inspection. The use of AR –that connects virtual and physical buildings in their environments at real-time– will ensure that the targeted perfor-mance in the design model is realised. INSIT-ER will thus eliminate the gaps in quality and energy-performance between design and reali-sation of energy-efficient buildings made of prefabricated components.
The new concept of self-inspection that is per-formed simultaneously with on-site processes has a strong contrast with the traditional post-inspection approach. INSITER will develop a new methodology for self-inspection during construction, refurbishment, maintenance and commissioning, along with a dedicated toolset. INSITER will substantially enhance the func-tionalities and capabilities of measurement and diagnostic instruments (like portable 3D laser scanners, thermal imaging cameras, acoustic and vibration detectors, real-time sen-sors) by means of a smart Application Pro-gramming Interface (API) and data integration with a cloud-based Building Information Model (BIM). The triangulation of Geospatial Infor-mation, Global and Indoor Positioning Sys-tems (GIS, GPS, IPS) will support accurate and comprehensive Virtual and Augmented Reality (VR and AR).

INSITER will develop a new methodology for self-inspection during construction, refurbishment, maintenance and commissioning, along with a dedicated toolset.


INSITER will substantially enhance state-of-the-art measurement and diagnostic instru-ments with wireless and easy-operation facilities through users’ mobile devices. Triangula-tion of Geospatial Information, Global and Indoor Positioning Systems (GIS, GPS and IPS) will support the 3D accuracy of these instruments. The data will be integrated in cloud-based Building Information Model (BIM) that evolves throughout the building’s lifecycle.


Within the overall aim, there are a number of specific objectives that relate to the en-hancement of the fucntionalities and capabilities of measurement and diagnostic instru-ments (like portable 3D laser scanners, thermal imaging cameras, acoustic and vibration detectors, real-time sensors) by means of a smart Application Programming Interface (API) and data integration with a cloud-based Building Information Model (BIM).


The tri-angulation of Geospatial Information, Global and Indoor Positioning Systems (GIS, GPS, IPS) will support accurate and comprehensive Virtual and Augmented Reality (VR and AR). INSITER has 3 major scientific and technological (S/T) objectives:


Objective 1: To eliminiate the gaps in quality and energy-performance between design and realisation of energy-efficient buildings (EeB) made of prefabricated components, by connecting the virtual model and the physical building on site in real-time through Augmented Reality (AR) for self-inspection during construction, refurbishment and maintenance.


Objective 2: To develop innovative INSITER Systems- a set of intuitive, robust and cost-effective hardware and software- for self-inspection by workers and other stakeholders during off-site and on-site working processes.


Objective 3: To develop an innovative INSITER Methodology, which consists of protocols and guidelines for self-inspection and self-instruction that enable workers of general contractors and subcontractors, site supervisors, technical experts, quality auditors, cli-ents and building occupants to use the methodology with the supporting INSITER Sys-tems (hardware and software).


The INSITER consortium consists of 14 partners: 10 industrial partners (3 large companies + 7 SMEs) and 4 research organisa-tions. SMEs are the largest group in the consortium; they play a key role, both in leadership of the project as well as in re-search, demonstration and exploitation. The INSITER project is driven by the industrial partners that are active and successful in their market areas, and thus are able to mobilise their clients and business partners to ensure the market implementation of INSITER results. High-quality research will be guaranteed by the involvement of renown EU research organisations, as well as by the leadership and coordination of industrial/SME partners with extensive experience in performing EU research projects. Together they build the critical mass for sound research and real impacts.



All main geographical regions of Europe (Western, Central, Southern) with their climate-related, regional and cultural char-acteristics are covered by the INSITER partners that represent 6 EU countries (Netherlands, Belgium, Germany, Bulgaria, Italy, and Spain). Generalisation and wide dissemination of the knowledge and project results are thus guaranteed. Moreover, there is a strong and proven commitment for teamwork since all partners have been engaged in collaborative projects with each other previously, either in research projects (EU or nation-al projects) or in relevant new construction and retrofitting pro-jects.
