What Is NRM In Construction?

Introduction To NRM

NRM2, or New Rules of Measurement 2, is a set of guidelines introduced by the Royal Institute of Chartered Surveyors (RICS) to provide a standard and detailed approach for measuring and describing building works for tender pricing purposes.

NRM Suite

Overview of NRM1, NRM2, and NRM3

The NRM suite consists of three separate volumes: NRM1 (Order of cost estimating and cost planning for capital building works), NRM2 (Detailed measurement for building works), and NRM3 (Order of cost estimating and cost planning for building maintenance works). The new editions of NRM were effective from 1 December 2021.

Purpose of NRM2

NRM2 allows for a consistent approach to producing bills of quantities and similar pricing documents, facilitating the measurement and description of building works components.

The transition from SMM7 to NRM2

NRM2 was introduced in January 2013 as a replacement for the Standard Method of Measurement 7 (SMM7) to prepare procurement and tender documentation [3].

Components of NRM2

NRM2 provides detailed rules for the measurement and description of building works, addressing all aspects of bill of quantities production, including the information required from the employer and other construction consultants.

Preparing Bills of Quantities with NRM2

NRM includes detailed guidance on preparing bills of quantities, with coding and work breakdown structures.

NRM2 and BIM (Building Information Modeling)

This standard can be used in conjunction with BIM for cost management purposes, ensuring accurate and consistent cost estimation throughout a project.

Benefits of NRM2

Using NRM2 brings several benefits, such as:

• Standardisation: NRM2 provides a uniform measurement and cost estimation approach, enabling all parties to work from a shared understanding and reducing discrepancies.
• Improved communication: By adopting a common language, stakeholders can communicate more effectively, streamlining the decision-making process and reducing misunderstandings.
• Accurate cost estimation: NRM2 promotes detailed and consistent cost assessments, allowing for more precise budgeting and minimising the risk of unexpected expenses.
• Enhanced project outcomes: With increased standardisation, communication, and accuracy, projects are more likely to be completed on time and within budget, ultimately leading to better overall results.

Training and Advice on NRM2

Contractors, subcontractors, and consultants can access NRM2 training and support through various platforms, including:

• Online resources: Discover valuable materials and tutorials on NRM2 implementation and best practices.
• Specialised courses: Enroll in tailored courses designed to provide in-depth knowledge and guidance on NRM2 application within the construction industry.

NRM2 in Practice

Taking off quantities 

Taking off quantities is a crucial step in construction projects, as it involves measuring and describing the necessary items following the NRM2 guidelines. This process helps ensure accurate cost estimation and consistent communication among stakeholders. Here is a simple step-by-step example of taking off quantities:

1. Refer to construction drawings and specifications to identify the items required for the project.
2. Measure and record the dimensions of each item using appropriate units by NRM2 rules.
3. Utilize dimension paper, spreadsheets, or specialised software to organise and record measurements systematically.
4. Calculate the quantities of materials and labour required for each item.
5. Compile the calculated quantities to produce a comprehensive bill of quantities (BOQ) or schedule of rates.

Examples of NRM2 application 

To better understand the practical application of NRM2 in construction projects, numerous case studies and tutorials are available online. Some examples include:

• A step-by-step guide on measuring excavation works for a foundation: This tutorial demonstrates how to accurately take-off quantities for excavation works, including calculating the volume of soil to be removed, considering the different soil types, and ensuring the measurements comply with NRM2 guidelines.
• Quantifying and pricing concrete works: This case study highlights how to measure the required volume of concrete for various structural elements, such as beams, columns, and slabs, and subsequently calculate the costs associated with these works using NRM2-compliant methods.
• Estimating masonry works: This tutorial showcases the process of measuring brickwork and blockwork quantities, considering factors such as the size of bricks or blocks, mortar joints, and openings, while adhering to NRM2 rules.

Comparison with Other Methods of Measurement

NRM2 directly replaces SMM7, and it provides a more detailed and structured approach to measurement, making it a more comprehensive method for pricing bills of quantities and similar documents [10].

Additional Benefits of NRM2

NRM2 provides several additional benefits to construction professionals, such as:

1. Increased Transparency: NRM2 enables stakeholders to have a clearer understanding of project costs and helps to minimise disputes over pricing and measurements.
2. Enhanced Collaboration: The standardised approach provided by NRM2 fosters better collaboration among project teams, making it easier to identify and address potential issues.
3. Improved Project Control: With a more detailed and accurate cost estimation, construction professionals can better control project budgets and schedules, reducing the likelihood of cost overruns and delays.
4. Facilitates Benchmarking: The uniform approach of NRM2 allows for more effective benchmarking, enabling construction professionals to compare their projects against industry standards and best practices.

Challenges in Implementing NRM2

While NRM2 offers many advantages, some challenges may arise: 1. Adapting to the New System: Professionals accustomed to using SMM7 or other measurement methods may need time and training to adapt to the new NRM2 guidelines.

1. Software Compatibility: Ensuring that project management and estimation software are compatible with NRM2 may require updates or even the adoption of new software.
2. Resistance to Change: In some cases, professionals may resist change and need convincing of the benefits of adopting NRM2.

Overcoming the Challenges

To overcome the challenges associated with implementing NRM2, construction professionals can:

1. Invest in Training: Providing adequate training and support to employees can help them adapt to NRM2 more easily and effectively.
2. Choose Compatible Software: Selecting software that is compatible with NRM2 will streamline the transition process and ensure all team members are using the same approach.
3. Promote the Benefits: Communicating the benefits of NRM2 and demonstrating its advantages can help overcome resistance to change and encourage stakeholder adoption.

Future Developments in NRM

As the construction industry continues to evolve, NRM guidelines will be updated and expanded to address new challenges and emerging technologies. Professionals should stay informed about the latest developments in NRM and be prepared to adapt their practices accordingly.

Conclusion

NRM2 is an essential tool for construction professionals, offering a standardised and detailed approach to measuring and describing building works. By implementing NRM2, professionals can improve communication, cost estimation, and overall project outcomes. Despite the challenges that may arise when adopting NRM2, with the right training, software compatibility, and promotion of its benefits, construction professionals can successfully transition to this new method of measurement and reap its rewards.
