Lean Construction Ireland Annual Book of Cases 2021 22 l f 2 Company Overview HAWTHORN HEIGHTS hawthornheights.co.uk Established in 1999, Hawthorn Heights started as a landscaping contractor working mainly on private dwellings and some small public works.The company has since expanded into completing large civil landscaping projects and the design and build of play parks, sports pitches and outdoor exercise facilities within the commercial and public sectors. It has become a major player within the Irish and Scottish markets with the headquarters based in Eglinton,Co.Derry. Ciaran Farren Author Overview & Background to the Lean Initiative Lean Initiative Undertaken – Lean Thinking, Tools, Techniques In 2017, Hawthorn Heights embarked on a cross border Intertrade Ireland business development project (FUSION Programme) working with the Institute of Technology Sligo (now Atlantic Technological University, ATU).The aim of the project was to carry out detailed analysis of the design, supply, and installation processes within the company. The overall process would then be optimised using lean and project management best practices to improve efficiency and create a new, bespoke 3D design function. (Up to that point, it was generally using 2D for design and outsourcing 3D design which was causing delays). It was hoped that in doing so, it would meet the demands of the changing market and fulfil individual client requirements. In addition, it was envisaged that a lean thinking mind-set would be embedded in the company, through the use of tools and techniques that would assist the project.The FUSION programme offered the company the input of academic expertise and supported recruitment of a project manager who would oversee the implementation. Running for eighteen months, the project would be monitored through monthly steering group meetings and quarterly progress management meetings (involving all stakeholders). On completion of the project, a full report was generated to assess the success of of the project. Intertrade Ireland recognised the impact from this project and presented the team with an exemplar award.

Process MappingAnalysis: With the project focusing on analysing processes and procedures, it was important to identify an effective way to assess how the company was preforming in these areas. Input from the academic advisor from IT Sligo (now ATU),Trevor McSharry suggested the introduction of lean tools and techniques to conduct the assessment. In order to ensure the project covered all aspects of the business, a process mapping exercise was conducted.The main benefit of this exercise was the visual flow map produced as it clearly showed how the business operated and was very useful in identifying areas were processes didn’t flow smoothly or areas that were under a lot of demand. It was a very useful tool for streamlining processes and/ or resources as required to ensure everything flowed in the most efficient way possible. It also highlighted bottlenecks and areas of the company that were under resourced, from a human resource or equipment perspective.The exercise led to the production of Figure 1: Process Flow Chart for Design, Construction and Completion Phases.
