Barriers | Descriptions | Reference |
---|---|---|
Technology-related
| Technical barriers affect and shorten project duration by improving construction order, and there will be communication issues and a lack of collaboration. | [1,2,3,51] |
Management-related
| Due to insufficient lean principles and experience on the team, there will be performance issues and poor productivity improvement. | [3,14,41,52] |
Resistance to change-related
| Construction industry attitudes and reluctance to change, as well as other types of barriers, have an impact on project management performance and monitoring efficiency. Lean construction principles are used by practitioners to improve supervision and performance. | [1,2,3,51,52] |
Poor performance-related
| Due to resistance to change from traditional working practices, Lean lags far behind other countries such as the United Kingdom and the United States. The lack of a stable policy explains the lack of standardization. | [25,37] |
Lack of awareness-related
| Most construction workers lack the fundamental skills required to apply Lean principles in a construction project. A solid understanding of lean awareness is required. Issues concerning information reuse and overall client satisfaction have an impact on what the construction industry could achieve. | [3,33,53] |
BIM Implementation Barriers | Descriptions | Reference |
---|---|---|
Lack of BIM knowledge-related
| Barriers of this kind show negative outcomes in a construction project. BIM is used as a tool to help reduce project costs and reveal important impacts on the construction industry. | [20,26,41,54] |
Lack of specified standard-related
| Failure to obtain the appropriate standard in BIM adoption in the construction industry contributes to negative productivity in the construction project and sector. | [13,15,55,56,57,58,59] |
Traditional methods-related
| BIM is being used as a tool to help reduce project costs and have a greater impact on the construction industry. Acceptance of BIM implementation and proper application fosters a positive teamwork mentality. | [2,14,60] |
High cost-related
| The logic of this emphasis, i.e., on process cost reduction, is problematic in New Zealand from the standpoint of BIM implementation. The budget savings sought by New Zealand clients are primarily in the construction process cost. | [20,26,37,54,61] |
Case Studies | Context/Challenges | Issues and Solutions | Key Outcome |
---|---|---|---|
Case Study 1: Transport Infrastructure Projects, New Zealand | The City Rail Link (C.R.L.) $4.4B projects will improve and connect Auckland’s entire rail network and support a growing population. It will enable up to 54,000 passengers per hour to travel more easily across the network. For the construction consisting of two 3.45-km-long tunnels and two new underground stations, accurate locating and mapping of existing key utility infrastructure was essential to success. | In such invasive construction activities, knowing where the existing utility infrastructure is located is essential to success. Technicians used a combination of Ground Penetrating Radar (GPR) and electromagnetic location (E.M.L.) to pinpoint the location of this key infrastructure in advance of construction works. | BIM process provides the construction team with full As-Built drawings pinpointing the exact location of critical infrastructure. It also supports marking out the construction site with visible markers. The process increases safety outcomes for workers and minimizes the risk of service strikes and disruption during construction. |
Case study 2: Water and Wastewater Reticulation and Treatment Operation and Maintenance (O&M) | Southland District Council (S.D.C.) is required to undertake repairs and maintenance for an extensive network consisting of sewerage schemes, wastewater pump stations, stormwater networks, and urban and rural supply schemes. The contract value is a $4M p.a. contract starting in 2010 and will carry through to 2023. This includes:
| 24/7 availability and response to customer requests. O&M services for water and wastewater reticulation systems and treatment facilities. Assistance in overcoming issues relating to drinking water through the upgrade of the water treatment plants. Skilled system users who can troubleshoot and transfer learnings to the S.D.C. team. Monitoring ensures the safety and quality of water. | The upgrade was done without interrupting existing operations and ensured the treatment plants were in line with the 2008 drinking water standards. Over the past three years, project execution achieved an excellent rating of 93% across 14 Key Performance Indicators (KPIs). Monitoring ensures the correct levels of safety and water quality are provided. The organization team was also able to apply the lessons learned to other areas of business provision. The contract has been delivered on time and within budget using the BIM approach. |
Case study 3: Trentham to Upper Hutt rail Project (T2UH) | T2UH involved double-tracking of 2.7 km of the Hutt Valley line between Trentham and Upper Hutt stations to enable trains to travel in both directions at the same time and deliver more frequent and reliable services. There is a real motivation for partners on the project to engage and learn together on the digital transformation team. | BIM development is the basis of design and encouraging collaborative processes at each stage of the project lifecycle (purchasing, design, construction, and asset management). This led to:
| Digital tools developed d on T2UH contribute to a more resilient, productive rail sector, and enhance outcomes on other infrastructure projects. The Trentham to Upper Hutt project and BIM pilot program have changed the way KiwiRail approaches projects in the railway corridor. Collaboration and standardizations were implemented for reduced errors. In comparison to traditional delivery methods, it was found that for a complex project in a live transport corridor, there was a significant financial benefit. |
