Lean Design in Hydraulic Infrastructure – River Defenses and Dikes - A Case Study From Peru

Abstract

The construction sector has been changed in different aspects since the implementation of best practices of lean construction and others. It is crucial to remark that those new methodologies have been trying to address construction issues related to the execution part but with little attention to the design stage.In Peru, the use of lean construction started as part of an initiative from the private sector and specifically in the execution part. In that sense, lean design was introduced later and always by the private sector. Little by little the public sector started to get used to lean construction. Nevertheless, in hydraulic infrastructure such as river defenses and dikes the progress of introduction lean design has been insignificant in the country. This paper describes step by step the implementation of lean design in capital projects related to hydraulic infrastructure in Peru specifically for river defenses and dikes.It is the objective of this paper to address the difficulties founded in the implementation and what strategies have been deployed in order to overcome those barriers. Two tools of lean design that were used are: set based design and value stream mapping along with concepts of change management.

Value stream mapping application for construction industry loss and waste reduction: a systematic literature review

“…This failure in communication between team members was also noted in the cases studied by Michaud et al (2019aMichaud et al ( , 2019b and Saurin and Sanches (2014). According to Bekdik et al (2016), Chuquín et al (2021aChuquín et al ( , 2021b and Ramalingam (2018), the cause of the defect was linked to the lack of training employees, compromising the quality and performance of the process.…”

“…It should be noted that not all the studies analyzed highlighted results or benefits from the VSM application as they did not present either of the two maps (Chuquín et al, 2021a(Chuquín et al, , 2021bEtges, 2018;Michaud et al, 2019aMichaud et al, , 2019b or presented only the construction of the current state map (Aka et al, 2017;Michaud et al, 2019aMichaud et al, , 2019bSaurin and Sanches, 2014;Vilventhan et al, 2019;Xie et al, 2018).…”

Set-Based Design in Construction Projects: Benefits, Difficulties and Trends

“…Table 1: Benefits of SBD adoption in the construction industry. (Chuquín et al, 2021b), 2. (Chuquín et al, 2021a), 3.…”

“…Table 2 shows the top-10 most frequently reported SBD adoption difficulties. The 'inadequate organizational structure for the adoption of SBD' (C1) is the most reported difficulty, which is related to the staffing requirements and organizational structure in the design disciplines of a construction project (Chuquín et al, 2021b;Gomez & Rameson, 2019). C1 has a major impact on some organizations because it is common to subcontract some of the design disciplines with specialized firms (Hassan & Le, 2021).…”

“…Several studies have shown benefits of implementing SBD in design processes. For example, Chuquín et al (2021b) applied a survey at the end of a design process with SBD, the findings showed that 72% believed that the quality of their work had increased, and rework had decreased. Besides, Chuquín et al (2021a) conducted a survey of the usefulness of SBD among the participants of a case study of a high-rise building.…”
