Using 4D BIM in the Retrofit Process of Social Housing
2015
There is a large stock of solid wall homes in the UK presenting poor thermal insulation and low energy performance. Although the UK Government has supported improvement efforts in the area, the identification of appropriate technical solutions that effectively improve the existing stock remains a challenge. BIM offers opportunities for building performance optimisation, through improved design and simulation. This research investigates how BIM could improve the retrofit process for social housing. This paper describes a research project looking into the use of BIM to develop what-if scenarios for retrofitting existing ’no-fines’ solid wall homes. The scenarios enable the analysis of alternative solutions considering costs, energy performance and user disruption. More specifically, this paper focuses on the use of 4D models to evaluate disruption for end users. The research process includes simulations, meetings, interviews, documents, and observations. Results indicate that the deve...
Building information modelling to cut disruption in housing retrofit
Proceedings of the Institution of Civil Engineers - Engineering Sustainability, 2016
There is a large stock of solid-wall homes in the UK with poor thermal insulation and low energy performance. Although the UK government has supported efforts to improve these buildings, the identification of appropriate technical solutions that effectively improve the existing stock remains challenging. This research investigates how four dimensional building information modelling (4D BIM) could improve the retrofit of social housing, specifically that of ‘no-fines’ solid-wall homes, through the development of what-if scenarios that enable the analysis of alternative solutions considering costs, energy performance and disruption to users. This paper focuses on the use of 4D building information models to evaluate disruption to end users. The results indicate that the development of such models supports a better understanding of the retrofit process on site. It also supports the definition of production plans with as minimal disruption as possible to users while delivering energy-or...
BIM and 4D planning: a holistic study of the barriers and drivers to widespread adoption
Building Information Modeling (BIM) and its different work streams, such as 4D planning (4D), are among the major drivers for change in the construction industry. The primary aim of this research is to create a holistic map of both the barriers and drivers affecting the industrial uptake of BIM and 4D through the use of an extensive literature review and a survey of contractors and consultants from the UK AEC (Architectural, Engineering and Construction) industry. This research demonstrates that while non-technical barriers such as the inefficiency in the evaluation of the business value of BIM and 4D; the shortage of experience within the workforce, and the lack of awareness by stakeholders are recognized by professionals as main barriers to BIM and 4D adoption, current research is still largely concerned with technical advancement of BIM and 4D technologies. A holistic map of the driving and restraining forces affecting BIM and 4D widespread adoption was provided. The tackling of the non-technical barriers identified will help bridge the gap between technology, end-users and their processes.

̶ The current housing crisis and demand for residential accommodation in Ireland has required a change in the construction industry. The introduction by the Irish Government of the temporary fast track planning arrangement for large scale housing developments delivers a key commitment of the Governments action plan for housing and homelessness. Under these new provisions, planning applications can be made directly to An Bord Pleanála (ABP) and not to a local planning authority as was previously the case. This introduction has required the design team to provide sufficient information to enable ABP to offer an opinion and give direction on any amendments required to allow the project to proceed to the application stage. If significant changes are requested, this will result in major redesign work for the architect and other design team members. By adopting BIM methodologies at this early stage, the design team has the potential to automate the process through early design collaborati...
Evaluating Social Housing Retrofit Options to Support Clients’ Decision Making—SIMPLER BIM Protocol
Sustainability
The UK government made significant commitments to upgrading the energy efficiency of seven million British homes by 2020, aiming at reducing carbon emissions and addressing fuel poverty. One alternative to achieve better energy performance in existing houses is retrofit. However, there are difficulties associated with retrofitting social housing. It is currently challenging to compare scenarios (retrofit options) considering costs, potential energy efficiency gains, and at the same time minimising disruption to users. This paper presents a Building Information Modelling (BIM) protocol aimed to support decision making by social housing owners. It adopts BIM to simulate alternative retrofit options, considering: (a) potential reductions in energy consumption, (b) 4D BIM for retrofit planning and reduction of users’ disruption and (c) simulation of costs. A what-if scenario matrix is proposed to support decision making in the selection of social housing retrofit solutions, according to...

Purpose The purpose of this paper is to identify how the newly emerging UK practice of “collaborative planning” (CP) for construction project delivery aligns with the advocated principles of the global last planner system (LPS) of production planning and control. Design/methodology/approach A mixed, qualitative, exploratory approach was adopted for the study. This entailed qualitative data through three techniques, namely: semi-structured interviews, documents analysis, and structured observation. In total, 30 in-depth interviews were conducted over a 12 month period with lean construction consultants, clients, main contractors, and subcontractors drawn from the building, highways and infrastructure and rail sector. In all, 15 projects were visited where practices were observed. Findings The study reveals that the current practice of CP in the UK partially aligns with the LPS principles. Where practitioners have heard of the LPS they believe it to be the same practice as CP. Researc...

This paper shows a detail implementation and lessons learned from the Last Planner System (LPS) in the context of a social housing program of the government of Chile. Specifically the "Condominio Juanita Aguirre" (CJA) project in the commune of Conchali in Santiago, Chile, which includes the construction of 80 apartments of 56 m2, in buildings of 4 stories high on a contractual period of one year. We followed the trajectory from the general contractor perspective, Oval Company, which has extensive experience in the construction of social housing. This company has obtained highly variable projects results in the past, and thus the company decided to implement the Last Planner System (LPS) in the CJA project. This research measures the results of the implementation throughout the construction process. Additionally, we make a comparison against previous projects of similar characteristics built by the same company with traditional management systems. Finally, the research sho...
