Abstract

This study aims to have a comprehensive view of the current housing crisis shortage of labour and low productivity and how new affordable homes could be built by utilising innovative construction methodology in the UK. Availability of affordable housing services has always been a central agenda for most nations across the globe and particularly in the UK. The developers majorly rely on traditional strategies and techniques. Even though some companies are utilising modern methods the implementation process is partial and insufficient.

The research has integrated interviews and surveys considering the project managers and employees of Swan Housing and Cherry Park, London respectively. However, thematic analysis for interviews and inferential analysis for surveys have been further chosen as analysis methods. 

The thematic analysis has established the importance of modular construction and 3D printing as important technological tools and techniques for enhancing the productivity and efficiency of construction. Findings from the study state that the implementation of modern innovative techniques and advanced technologies has been efficient enough in resolving the housing crisis issue in the UK.

Moreover, it has helped in the construction projects of affordable houses thereby helping the employees actively participate in the projects based on the training and development sessions provided to them. The study highlighted that as the techniques have been aligned with the objectives and vision, therefore, the efficiency level of the companies in dealing with the issues has been high showcasing the increased opportunities for positive contribution to mitigating the housing crisis within the UK. 

The correlation and regression tests have also reflected the high statistical significance of the variables thereby showcasing the linear relationship. The study has concluded the requirement of technology innovation and green building methods to be suitable for gaining a competitive advantage in the construction sector and providing a solution to the house and crisis in the UK through affordable housing.

Chapter 1: Introduction

1.1 Research Background

Availability of affordable housing services has always been a central agenda for most nations across the globe and particularly in the UK. Governments are making different programs and initiatives to achieve the target of affordable housing for the population, yet a large percentage of people and younger generations are unable to live decently in the provided service. It has created a huge loophole in terms of housing shortage and insufficient use of innovative techniques in construction projects. Poor knowledge of the construction businesses, natural disasters, and demolition of old houses and buildings are collaboratively resulting in increasing the demand-supply gap for affordable housing and construction in the UK (RICS, 2018). Especially due to Brexit and pandemics the existing gap had escalated. The migration regulations and rules implemented due to Brexit have also sourced the availability of unskilled labour as previously Sourcing was mainly done from European countries (Armstrong, 2016). It is still expected that the impact will be exaggerated due to the ongoing pandemic and achieving the target of affordable housing will become more difficult. Therefore, the construction businesses in the UK need to adapt technology enhanced advanced and enabled construction approaches in order to ensure efficiency, manageability, sustainability, and profitability within the sector.

1.2 Problem statement

The UK is experiencing a different crisis associated with scarcity of housing facilities which is caused due to low productivity in the construction industry and high inflation. In addition to that labour shortage and skilled workforce are also significant causes of the crisis in the housing and construction industry of the UK (RICS, 2018). Lack of research and development is yet another significant reason for the scarcity of housing as the companies and businesses are not investing and researching the innovative aspects for utilising the modern construction method so that it can contribute to addressing the issues. Compared to other sectors that have completely changed the ways of a business operation due to research development and innovation, the construction in the stream and the housing facilities are still driven by the traditional approach in the UK. The developers majorly rely on traditional strategies and techniques. Even though some companies are utilising modern methods the implementation process is partial and insufficient. Therefore, the use of innovative construction methods in construction projects within the UK in order to provide affordable homes has become a significant aspect.

1.3 Aims and objectives

Research aim

This study aims to have a comprehensive view of the current housing crisis shortage of labour and low productivity and how new affordable homes could be built by utilising innovative construction methodology in the UK.

Research objectives

• To evaluate and understand the innovative aspects of the modern methods of construction and by assessing their impact assess the impact on affordable housing in the UK
• To identify the extent to which the innovation in the construction method enhances productivity and how it affects the housing and construction sector of the UK
• To address issues and importance of the modern method of construction to cope with the labour shortage in the UK
• To provide recommendations to the developers and contractors in the UK for utilising modern methods of construction and mitigate the issues

Research Questions

• What are the different innovative aspects of utilising modern methods of construction and what is the impact of the innovations on affordable housing in the UK? 
• To what extent innovation in the construction method enhances productivity and the construction sector? 
• How could the construction industry of the UK make remarkable changes in building approach by implementing further innovations given by modern methods of construction? 

1.4 Research Rationale

It is being expected by the construction developer that the target of 300000 new homes every year cannot be materialised due to the crisis of free trading between the UK and European countries (Savage, 2021). Therefore, the demand for affordable housing can exceed the supply which will result in an increased number of the population in the UK living in poor housing conditions and homelessness. It will also result in making the cost of housing in the UK increase exponentially and significantly affect the general budget of households (Armstrong, 2016). The large population might end up struggling with daily basic needs such as childcare expenditure, food, and transportation among others. In the long run, it will also reduce the scope of having a good quality of life. It is therefore important for the businesses in the UK and for the government also to promote strategies to move away from the traditional technique in the construction business and implement a more blended approach for building affordable houses (Go Construct, 2022). Therefore it can be stated that it is a significant aspect to investigate the ways in which the housing crisis in the UK currently is associated with low productivity and labour shortage. Therefore this study has the purpose to identify the ways in which research development and the use of innovative construction methods can foster affordable housing agenda in the UK.

1.5 Structure of the dissertation 

The literature review chapter will investigate the views and opinions of the authors and writers and will also compare and contrast case studies for evaluating the extent to which the existing strategies and initiatives in the construction businesses of the UK meet the housing demands. In addition to that, the issues of labour shortage and productivity will also be highlighted.

The literature review chapter will be followed by a methodology that identifies the strategies by which the researcher has collected the data and information in this study. Both survey and interview, which is a mixed method for collecting the data and information, have been used by the researcher. In the following chapters’ findings and data analysis has been carried out where the opinion and views of the interview participants and survey participants have been compared and contrasted with the secondary data that is collected by the researcher from different secondary sources.

Lastly, in order to achieve the research aim and objective, the researcher has concluded with the overall finding in the study and has generated a coherent understanding of the ways in which modern methods and techniques can be used by the construction businesses in the UK to enhance the existing construction strategies and improve the housing condition in the UK.

Chapter 2: Literature review

2.1 Introduction

The study focuses on interpreting peer-reviewed literary sources such as journal articles, books, magazines, and so on for obtaining authentic and reliable data considering the stakeholder management scenario of the UK-based construction companies. It emphasises the innovative aspects of modern methods of construction and their impacts on affordable UK-based housing. It also focuses on depicting the innovation in the construction sector impacting the enhancement of productivity in UK-based housing. The study focuses on establishing an understanding of the issues and significance of modern methods of construction to cope with the shortage of labour in the United Kingdom. It focuses on suggesting recommendations for developers and contractors in the UK. 

2.2 Housing crisis in the UK

The Government of the UK for several years has failed to deliver the promise of achieving adequate affordable housing security for its citizens. For example, the objective of 300000 houses every year has failed, throwing the citizens of the country to face the housing challenges that also affect not only the young generation but individuals belonging to every age group (Savage, 2021). The government already has interventions to deal with the housing crisis yet the increasing cost of housing is exceeding the average and annual salary of the citizens in the country making it more difficult to have affordable houses for the citizens.

Reportedly 8 times more payments are needed to be given by the full-time workers in the UK in order to afford a home. As per another report, 3.6 million citizens in the UK live in overcrowded houses (Power, 2019). The pandemic and Brexit are later reasons for the global financial crisis in 2007 have been the main reason to speed up the housing crisis in the UK (Ferrari, 2015). For example, the below image shows the plan and ways in which technology and modern methods of construction have been used to build the first Eco town in the UK. This construction plan can be used in the future as well in order to re-shape the housing system in London and across the UK by the construction businesses.

Figure 1: First eco-town of the UK

It has not only led to re-shaped the political, social, and economic forces over time but the housing system has also been significantly changed due to the changes or cuts in public expenditure. Therefore, increased housing expenses have also increased the impact on the low-income population in the country (Modulek, 2022).

Reportedly the housing crisis in a country occurs when a major cap of a population is unable to access affordable safe and decent housing. An increase in the credit and a decrease in the supply of affordable houses along with a growing population and demolition of social housing are also reasons for the expensive housing problem in the UK along with the global financial crisis (Power, 2019).

The government however is trying to provide the population for dealing with the issue of the housing crisis with enhanced production and investments to purchase housing. The employer as a result of this can have a huge skill set of a population. However, the strategies and initiatives are not adequate to bring equilibrium in the forces of supply and demand for affordable houses (Gibb, 2019).

2.3 Innovative aspects of the modern methods of construction and their impact on affordable housing in the UK

3D Printing

In order to achieve the affordable housing targets, there are different views and opinions of authors and writers that appraise the innovation that is currently being considered. These innovations mainly focus on enhancing productivity and activities in the construction industry.

One such significant innovation is 3D printing and offsite construction (Hashemi and Hadjri, 2014). 3D printing is considered a cost-effective strategy compared to traditional methods. Reportedly implementation of 3D printing replaces external and internal foundations of the walls of the houses thereby reducing the cost of house angle by 30% (Schudtet al., 2021).

3D printing for metal frames is also being developed that is expected to positively incorporate the impact on the housing sector (Tobi et al., 2018). The twin wall technology is also a widely utilised method in the construction industry which combines in situ concrete and pre-made concrete helping the designer and builder in terms of strength and speed of the structure. This technology occurs and is used when two walls that are premade are reinforced and joined before filling up the gap with the concrete. It is also used to join concrete floors and walls together and it is extremely economical and quick to implement (Brissiet al., 2021).

Figure 2: 3D printing (Twin Wall system)

(Source: Bisht, 2020)

Precast Flat Panel System

It will ensure sustainable durable and improved housing construction saving costs on labour and material (Bisht, 2020). The example of using 3D printing can be considered from the business operation of the Stewart Milne group which uses full-time research and development responsible for the use of 3D printing and design in different construction projects in the UK (Hossain et al., 2020). The projects currently by the company include 3000 home communities in Aberdeen.

Offsite construction

Examples of offsite construction similarly can be generated from the urban Swan Housing which is focusing on developing a configurable volumetric townhouse concept (NHBC Foundation, 2022). From the below image it can be identified that the social purpose and objective of the company is continuous growth with an effective emphasis on the commercial aspect and the use of innovative strategies in the housing projects. In order to achieve the social purpose and objective, the company is developing a configurable volumetric townhouse concept that follows the growth and commercial prospect (Brissiet al., 2021). In terms of innovation, the volumetric townhouse concept has been maintained as creative and inventive.

Figure 4: Social purpose and objective of SWAN Housing

(Source: RICS, 2018)

In order to secure the future manufacturing capability of the organisation the company acquired SIG Building System and formed better opportunities for bringing modular townhouses to different places in the UK (Brissi et al., 2021). 

Precast foundations are yet another significant form of the modern method of construction which are produced and prepared on-site in a warehouse or factory by using a reusable mould. The precast foundation has the ability to get attached to other panels for creating a particular form of structure used for walls and floor. The precast foundations are an extremely practical method of construction due to their economic and efficiency aspect.

The durability of the product is extremely rigid even in poor weather and therefore a wide range of use and application of the precast foundation are being identified in the modern method of construction (Brissiet al., 2021). On the other hand, offsite construction technology from Cherry Park for the bathroom pods has been found to be incorporated by the company. In addition to this, the installation of the unitised façade has also been evident in this project reflecting the third stage of the overall project.

Furthermore, it has emerged from the reports of the company that the company with the use of modern methods has efficiently helped the company in improving its performance in the market thereby reflecting the improved position in the market. However, it can be stated that the project conducted by Swan Housing has been efficiently conducted reflecting the modifications in the third stage.

2.4 Productivity challenges due to the impact of Brexit and the pandemic

According to Koc and Gurgun (2021), the regulations of Brexit also may hamper the establishment of effective project management of stakeholders within UK construction firms. 

With the target of the government to set 3,00,000 new homes built every year by the mid of 2020, there has been an immediate need to find the perfect combination and technology between sustainability quality and efficiency to meet the target (Gupta et al., 2018). Modern methods of construction vary in benefits and type. Most of the homes in the UK still are built by using traditional bricks and block approaches. However, the modern method and alternative methods which are different from the approach are increasingly being adopted and common particularly in the construction of social housing.

Therefore the modern methods of construction can be defined as a collective term of alternative construction practices (Williamson, 2019). Factory production which is on site of different parts and components of a property is the common characteristic of the modern methods of construction. It includes a readymade roof, floor wall or even the entire room that has the ability to be transported to the end destination for assembly and final outlook in a matter of a few hours. 

Figure 6: Impact of COVID-19 on construction companies in the United Kingdom

Source: Koc and Gurgun (2021)

As shown in the figure above, the impacts of COVID-19 on the construction firms of the UK increased by the end of 2021 while the productivity of the construction firms was reduced. Moreover, the ongoing lockdown as a result of the pandemic also initiated a set of issues regarding the incorporation of effective public relations management (Koc and Gurgun, 2021). The situation, for example, hampered the communication channels between the stakeholders and the construction firms like “Accord” or “Brick by Brick”, in terms of reducing collaboration and coordination between them. Moreover, the migrant labours were forced to shift to their native origins as a result of the prolonged lockdown and pandemic, thus creating a void in the labour resources of the construction firms (Koc and Gurgun, 2021).

2.5 Young generation and Labour force issues in the construction industry of the UK

According to Ferreira et al. (2021), the COVID-19 outbreak had a negative impact on stakeholder participation in the UK’s construction industry, resulting in decreased productivity and job losses. In this regard, the issue of a labour shortage within UK-based building projects was developed. Additionally, the pandemic’s prolonged lockdown created a number of problems with the adoption of efficient public relations management (Jang et al., 2021). 

The first and most commonly used modern method of construction is the 3D volumetric construction. It is also known as modular construction which consists of units that are being produced within a controlled environment before getting transported to the site and the controlled environment most of the time are warehouse or factory. The 3D volumetric construction can range from making the base unit to or installation of the finished internal wall assembly. As the production of the 3D volumetric construction is produced in a controlled environment the use of similar materials allows consistency and speed along with maintaining precision and overall quality. A flat slab is another modern method of construction which involves the placing of a slab made of concrete which is reinforced and placed with concrete columns (Brissiet al., 2021). Therefore the need for the beam is minimised. Apart from that, the benefit of this modern method of construction is that it also allows restrictions on the height between the floors providing the builder with better flexibility and reducing the time needed for the construction (Ferreira et al.,2021).

Source: Statista (2022)

As said by Jang et al. (2021), as a result of the unemployment scenario due to the pandemic, the shortage of labour became a significant issue within UK-based construction firms. The above figure shows how the regulations of Brexit also impacted the construction projects in terms of reducing effective monitoring and management. The formation of efficient project management of stakeholders within UK construction enterprises may also be hampered by Brexit restrictions (Ferreira et al., 2021).

2.6 Extent to which the innovation in the construction method enhances productivity and affects the construction and Housing sector of the UK

The effectiveness of using the innovation in the construction method to enhance the productivity and impact on the housing and construction sector of the UK can be identified from the business operation and innovation of customer build enablers and developers in England, TOWN (NHBC Foundation, 2022). TOWN, in this case, refers to the project that is being incorporated into the construction sector for developing a sustainable living environment (Kuzmin, 2018).  In order to create sustainable and workable places, TOWN uses urban extension and regeneration development. The innovative aspect of TOWN is the use of a closed panel timber frame system. Personalized and custom-built purchases are being configured by the organisation to maintain a competitive advantage. More than 5200 homes have been developed by the company so far and it is also focusing on implementing modern methods of construction across future development (NHBC Foundation, 2022).

Figure 8: Closed panel Timber frames

(Source: RICS, 2018)

In addition to that timber frame is another modern method of construction involving a range of structural frames made of the site, warehouse in a factory like internal and external wall roof floor for helping combine the structure of the building that can be clad in another material like on-site brick and block. It is also a sustainable method of construction that uses renewable materials and offers the builder and the designer a greater deal of flexibility in terms of the appearance and layout of the entire property (Ferreira et al.,2021). 

Figure 9: Precast panels

(Source: Cement.org, 2022)

The precast panel in addition to the above-discussed methods of construction uses wall and floor units that are transported and made of side and are erected on site forming the solid structure. In different sites where repeated projects are being made this form of the panel is considered ideal for use. It also offers quality accuracy and speed which is similar to the pre-prepared method. Due to its ability to use the factory-made components that are further followed by rigid processes before easily being able to erect on site. The precast panel also includes door windows and furniture that allows the Builder and the designer a great extent of flexibility in the production (RICS, 2018). 

Although businesses and construction projects are using renewable sources for the construction of building concrete is a very important material in construction due to its longevity, resistance rigidity strength and other similar qualities that ultimately make the use of a concrete floor and wall key aspect to make a long-lasting and solid structure. It is also called reinforcement steel which allows the carrying of heavy loads making the overall strength of the concrete floor and wall exponentially increases and becomes ideal for usage on the ground floor. 

2.7 Future scope and innovation 

The idea of inclusivity is fundamental to both stakeholder and ethical thinking, and it is easier to implement ethical behaviour within an organisation that takes a stakeholder perspective (Rajhans, 2018). All parties involved in the project or who may be impacted by it are considered stakeholders (Xia et al., 2018). According to Rajhans (2018), a stakeholder management method can be built when the project manager has evaluated the stakeholder traits and classes as well as their position regarding the project. The degree of direct contact and community involvement provided to the external stakeholders determines whether massive infrastructure projects succeed or fail (Xia et al., 2018). 

As said by Pedrini and Ferri (2018), contractors work in partnership with the client and the neighbourhood. This is crucial for infrastructure and revitalisation projects, and it is advised to involve government financing organisations in the cooperation. It suggests joint venture strategies with significant outside parties, such as environmental organisations. Businesses that interact and establish connections with these groups on a corporate level will be better equipped to handle them if issues occur on a project level. The contractor joins a neighbourhood-based programme like the Considerate Constructors Scheme. Contractors should create Community Policies to enable them to forge stronger links with their host communities, as they see the communities in which they operate as essential to their success (Lehtinen et al., 2019). It can be contended that contractor participation in community projects raises the firm’s ethical standards and social responsibility image, and it is proposed that a community policy might be centred on initiatives like education, enterprise or training. 

Furthermore, as opined by Khan et al. (2021), maintaining a strong relationship with the media, seeing them as vital stakeholders, and starting open and reliable communication with them from the beginning are all necessary for generating positive publicity. The public and different government entities’ perceptions of a project can be significantly influenced by the media (de Oliveira and Rabechini, 2019). It is obvious that UK housing construction firms must place a significant obligation on the client to ensure that these principles are established and maintained from the beginning because sustainable construction includes the requirement to account for the present and future conditions of external stakeholders (Khan et al., 2021). 

Apart from the discussion of stakeholder management, it can be stated that concerning the construction sector, there is a huge scope for innovation. In the UK, the development of technology has been found to be the highest thereby making the nation the technological hub (Badi et al., 2021). Advanced technologies such as machine learning, IoT, robotics and many more have been found to be highly used in the nation reflecting the sound technological infrastructure. In this regard, it can be stated that the construction industry has the scope of innovating their working systems in future years thereby using modern technologies. Moreover, following the lean manufacturing method, the construction industry can potentially help the companies in improving their production level thereby increasing the level of efficiency. 

2.8 Literature gap

The study did not focus on the strategies for ensuring the safety and security of the stakeholders associated with housing construction projects in the United Kingdom. It did not cover the aspects of sustainable building or construction in terms of minimising the risks associated with safety and security among the stakeholders. 

2.9 Summary

The discussion in the literature review counts towards accumulating information and data regarding the housing crisis and strategies by which the modern methods of construction in the UK are achieving the requisite changes. Processes of innovation in different projects in London focus on developing new ways of building more high-quality homes at a comparatively faster rate. The section also includes a discussion concerning the modern methods that are used by Cherry Park, London for their construction projects reflecting the bathroom pods. On the other hand, it can be stated that apart from the management of stakeholder concerning the construction sector, opportunities for technological development has been high for the companies in future years. However, it can be stated that with the help of technology and a lean manufacturing system, projects can be improved thereby integrating innovation at a high level. 

Chapter 3: Research Methodology

3.1 Introduction 

The methodology section of research helps in selecting methods that can bring out the true essence of the study and validate the overall research. In addition, it assists the researcher in understanding in which direction the research needs to be conducted along with the procedure that needs to be followed. The concerned section of this research, therefore, deals with the selection of research methods such as the philosophy, design, and approach along with the data collection and analysis. However, the purpose of this research along with the validity, reliability and ethical maintenance has been discussed in this section thereby improving the quality of the study. 

3.2 Research purpose

The purpose of the research is to meet the set objectives of this research that assist the investigator in completing the research within the desired time. It mainly aims at accomplishing the framed questions of this research thereby helping the researcher in improving the validity of the findings as well as the results. Thus, the questions that the study aims to answer are provided below. 

• What are the different innovative aspects of utilising modern methods of construction and what is the impact of the innovations on affordable housing in the UK? 
• To what extent innovation in the construction method enhances productivity and the construction sector? 
• How could the construction industry of the UK make remarkable changes in building approach by implementing further innovations given by modern methods of construction? 

3.3 Research philosophy

Accepting a belief that creates a pathway for the collection of data or information and its application can be termed to be the research philosophy. It essentially deals with the development of knowledge thereby making the choice of the nature of the collected data and its source (Hürlimann, 2019). In addition, it reflects the thought process of the researcher that sheds light on the level of reliable collection of information for the study. Concerning the research onion, pragmatism, realism, positivism and interpretivism have been the different types of philosophies in research that investigators generally make use of while conducting studies (Madden, 2022). The present research follows a mixed data collection method and thus positivism philosophy has been chosen and applied for the same. 

Positivism philosophy, as stated by Marsonet (2019), is the kind of belief where the researcher depends on the “factual knowledge” that is obtained with the help of observations instead of any biased opinion or information. It furthermore helps the researcher in structuring a general understanding of the conducted study thereby improving the research quality.

One of the cardinal reasons for selecting positivism philosophy is that it depends on general facts rather than any kind of personal reflection (Alharahsheh and Pius, 2020). Interpretivism has been rejected as it involves biased information and does not carry out facts. However, unlike interpretivism philosophy, positivism does not interpret the study elements but rather gains understanding from the observations. 

3.4 Research approach

Addressing the planning and the procedure with the help of complete assumptions can be stated to be the research approach. In this context, with the help of approach systematic data can be collected for the research that can deliver essential results for understanding the research’s topic (Cantelmi et al., 2021). It furthermore helps in mitigating the problem of the research thereby selecting data that possess proper nature concerning the study. Following the strategy of this study, an inductive approach has been chosen out of the deductive and inductive approaches of the research. As opined by Azungah (2018), an inductive approach or reasoning is termed to be the “bottom-up” approach where the researcher creates a pattern of the study based on the observations made concerning the data collected. Additionally, it assists in developing a theory at the end of the study thereby improving the validity of the research. 

As emerged from studies, the inductive approach positively contributes to mixed method research where both qualitative and quantitative data are gathered. The deductive approach has been denied for this study as it depends on hypothesis testing thereby only supporting quantitative research (Wardani and Kusuma, 2020). However, the selection of an inductive approach has been appropriate as it helps the researcher in providing general conclusions based on specific observations. 

3.5 Research design

Arranging conditions for conducting research are usually termed research design. As per the words of Dannels (2018), design refers to the technique or method that the researcher chooses in order to style up the collected data along with the results or analysis. In addition to this, the design of research considers various features of the study such as reliability, credibility, and validity, and intends to improve the same. In this current study, an explanatory research design has been selected that falls under the broad head of conclusive research. Explanatory design is also known as a casual design in the research context. The selection of this design can be mentioned to be appropriate as it explains the data collected following the data collection methods. 

Upon further discussion, one of the major reasons for choosing this design has been its capability to explain the elements of the study thereby providing results of both quantitative and qualitative data. The descriptive design has been rejected as no hypothesis is being developed for the study (Cantarelli et al., 2020). Thus, it can be stated that the choice of explanatory design has been justified as it considers both kinds of collected data and helps in effective analysis of the same. 

3.6 Research Strategy

Strategy in research refers to the planning of action that helps in deciding the direction of the study thereby shaping the thought process of the researcher (Oliva, 2019). The current study has incorporated a mixed strategy reflecting the inclusion of both qualitative and quantitative data. In this case, it can be stated that a qualitative strategy has been undertaken with the consideration of the interview session. On the other hand, quantitative data has been also integrated into this study in the form of survey questionnaires. Thus, it can be stated that a mixed method has been selected for the research that helps in collecting vast data for the study. 

3.7 Data collection and analysis

Collecting data is one of the primary tasks of an investigator that helps in keeping a step ahead for conducting the study in an effective manner. Concerning the sources of data collection such as primary and secondary, data have been collected from the primary sources reflecting the conduction of interview and survey sessions thereby meeting the mixed strategy of this study. In this study, 5 project managers each from Swan Housing and Cherry Park, London have been considered.

Furthermore, five semi-structured questions have been incorporated into the study thereby making each session a maximum of 10-15 minutes. Interview sessions have been conducted on an online basis reflecting the usage of the Zoom or Weber platform. On the other hand, an online survey has been conducted thereby selecting 40 employees in total from Cherry Park, London and Swan Housing. 

Concerning the data analysis, following the interview responses, a thematic analysis has been integrated where the use of secondary resources has also been made. Furthermore, considering the responses to the survey, statistical analysis has been conducted representing the integration of several tests like correlation and regression. The use of excel charts for analysing descriptive survey responses has been incorporated. However, for conducting inferential analysis reflecting the statistical tests, SPSS has been considered. 

3.8 Reliability and validity 

The collection of the data following both the methods has been made from reliable sources. In order to prove the authenticity of the study, the zoom calls have been recorded however as they are confidential, therefore, the recordings are not published. The use of secondary sources for the thematic analysis conducted has been made reflecting the consideration of authentic books, articles, online websites and journals. However, the study can be stated to be valid as it has obtained information from “real-life” participants reflecting both the interview and the survey. 

3.9 Ethical consideration

Consideration of ethics is an important task for a researcher especially when the study involves real-life respondents. As the study incorporates interviews, certain ethics have been maintained that have potentially improved the quality of the research. The interview responses have been secured in a password-protected laptop and access to the same has been restricted. Furthermore, before the conduction of the interview and survey, consent from the participants has been taken thereby improving the validity of the research. However, for secondary resources, blogs have been avoided and only authentic websites, journals, books and articles have been considered. 

3.10 Summary

The current section presents the selection of the research methods along with the justification that helps in increasing the validity and reliability of the study. In this regard, the study has chosen positivism philosophy, inductive approach, and explanatory research design. Moreover, a mixed strategy has been followed reflecting the consideration of both quantitative and qualitative data. The research has integrated interviews and surveys considering the project managers and employees of Swan Housing and Cherry Park, London respectively. However, thematic analysis for interviews and inferential analysis for surveys have been further chosen as analysis methods. 

Chapter 4: Research Analysis and Findings 

4.1 Introduction

The issue of labour shortages is being addressed through the help of recruiting skilled and efficient manpower. The literature review has stated the precast flat panel system has an important modern construction method that provides an alternative to the construction activities conducted at the site of the project.

This method is suitable for mass production of the construction components at a particular facility that helps the construction companies to meet the recurring requirements. This process is beneficial for coping with the labour shortage as it helps to solve the issues with demand speed of manufacturing while also ensuring the consistency of the production. The thematic analysis stated BIM as a digital method of designing the construction projects and buildings for planning affordable housing projects in the UK while also copying with the shortage of liver in the country by proper allocation of resources and materials.

The digital modelling methods are beneficial for improving the collaboration and communication at the project site while also undertaking the approach of model-based cost estimation. Better coordination and class detection for the resources is possible with the use of modern construction methods and techniques. 

Provide recommendations to the developers and contractors in the UK for utilising modern methods of construction and mitigate the issues

Strategies for the developers and contractors in the UK for utilising modern methods of construction along with mitigating the issues include developing joint venture strategies that will be helping them in handling and establishing connections with the groups on a corporate level. Contractor participation in community projects will raise the firm’s ethical standards and social responsibility image.

The thematic analysis has stated the requirement for reducing the cost of construction for increasing affordable housing availability in the UK housing market.

The literature review also supports the same by providing details regarding modular construction and fabrication that can significantly reduce the cost of construction along with reducing the overall cost of housing in the country. Hindi the objective is accomplished as the developers and contractors can use sustainable and alternate materials contributing to greater quality despite lower expenses that can help to solve the housing crisis in the UK. 

6.3 Recommendations 

The government authorities in the UK are recommended to provide more housing subsidies and lower the land value tax. This is needed for allowing the developers to construct housing estates at low cost for being able to offer affordable housing to the masses. Also, the construction companies need to integrate disruptive and innovative technology like artificial intelligence and big data for accurately forecasting the materials required for construction for the purchase of the right quantities to eliminate wastage. The construction project manager’s recommended using modular construction whenever possible for saving construction costs with prefabrication while also improving delays due to weather and other geographical factors.

The use of BIM technology and 3D printing are essential for accurately planning and designing the construction of affordable homes. 3D printing is recommended to be popularised during the construction of affordable homes for reducing waste while being more flexible and speedier during the design and construction phase.

The builders are recommended to use BIM during construction project planning for reducing risks related to construction and the cost while visualising the entire project during the preconstruction phase. The technological tool is recommended to be utilised for improving the process of scheduling and resource sequencing for keeping the productivity high at all times and not keeping any resources idle.

This can also help to achieve better collaboration and communication among the workers and engineers working on the site. The builders and developers are also recommended to apply the principles of stakeholder management for ensuring that the communicate with transparency and openness with everyone to understand their queries and inform them regarding the project progress based on their interest and power.  

6.4 Recommendations for future research 

The future scope of this research could be to compare the affordable housing infrastructure and scenario of the UK with other countries like South Korea or Estonia for evaluating how these countries offer the highest quality of affordable housing to their citizens. This could result in analysing the plan and procedures followed by such countries that could be successfully replicated in the UK to mitigate the housing crisis.
