The NEC contracts were designed to promote collaboration, flexibility, and risk management throughout the project lifecycle. The first edition, NEC1, was published in 1993, followed by NEC2 in 1995, NEC3 in 2005 and NEC4 in 2017. These contracts have different pricing and procurement options, such as target costing or the traditional ‘lump sum.’ Each subsequent edition incorporated feedback from users and reflected evolving best practices in project management and procurement. NEC4, introduced in 2017, builds upon the principles of its predecessors while incorporating updates and enhancements to address contemporary [...] implementation of these options within infrastructure projects. Following this comprehensive analysis, the section will culminate in the presentation of results, synthesizing findings to formulate a best practices guideline. This guideline will serve as a roadmap for leveraging Option C and X22 within the NEC4 contract framework to facilitate successful collaboration and project outcomes in the construction industry. 3.1 Collaboration in construction Delivering infrastructure projects to their pre-defined objectives is a challenge due to complexities and uncertainties that often exist (Ahiaga-Dagbui, Tokede, Morrison, & Chirnside, 2020; Rosander & Kadefors, 2019). To deliver the project required by the client, many organizations work together in the construction industry (Faris, Gaterell, [...] Contract 4th edition (NEC4), is crucial to ensure effective project cost and risk management. These contracts are designed to address and mitigate common issues associated with large-scale projects, offering a structured framework that promotes collaboration, risk-sharing, and efficient management throughout the project lifecycle. The New Engineering Contract (NEC) is known for its comprehensive set of tools that facilitate effective communication and cooperation between project stakeholders (nec, 2024). The NEC4 contract, short for New Engineering Contract 4th edition, is the latest iteration of a suite of contracts developed by the Institution of Civil Engineers (ICE) in the United Kingdom. The NEC contract series emerged in the 1990s as a response to the perceived shortcomings of",
