Chartered Quantity Surveyors’ Perspective on Building Information Modelling

Foreword The advancement of technology in recent years has provided our professions and industry with significant positives in terms of driving efficiencies, performance and standards. This level of technological progression is unlikely to slow down in the future but, to the contrary, the next ten years is predicted to witness significant changes in the way we do business and the way we can offer services. One recent example of this is the introduction of Building Information Modelling (BIM). As a professional body striving for high standards and excellence, we are delighted to see that government acknowledge and appreciate the value that BIM technology brings to our processes and systems in the built environment. Initially committed to in the Forfás Construction Sector Strategy, the Office of Government Procurement has shown its intention to introduce BIM on a mandatory basis for certain public works. This is a positive development and one that we believe will instil some level of confidence that BIM is worth investing in to deliver the type of projects for our future.

I have no doubt that the Quantity Surveying profession will meet this increased demand for BIM services and will be key advocates for embracing and advancing upskilling for our sector. Our recent survey of QS members indicate that the vast majority of QS practices have either adopted BIM or have a strategy in place to implement BIM in the near future. This is encouraging and highlights that the QS is a key component of this collaborative technology process. As an organisation, our objective is to provide assistance and supports to individual members during the implementation process and I look forward to tackling these challenges with the support of my committee and the SCSI executive.

Chartered Quantity Surveyors’ Perspective on Building Information Modelling

Introduction Building Information Modelling (BIM) is one of the most promising developments in the modern construction industry. With an increasing level of collaboration amongst industry professionals in recent years, BIM is seen as an emerging technology which is revolutionising how buildings are designed, constructed and operated. The growing popularity of BIM globally in the construction industry amongst all professional disciplines has seen it move from the research paradigm into a commercial reality. In a strengthening construction sector where output is currently increasing to 7.5 % of GDP, QS practices are showing an improved level of confidence following the industry stagnation of the past. With this improved confidence, our report shows that more firms are gearing up to accept BIM as a technology for the future. Benefits of BIM include increased visualisation for client’s at project concept stage, the opportunity to construct the building before construction stage which results in building it right. Most importantly BIM optimises facilities management through the life of a building.

Recent economic forecasts predict economic growth of 3.5% in 2018 with a satisfactory level of optimism in the near future. At present, our capacity to deliver on projects is already challenged due to the lack of suitable graduates and trades. This may require urgent action to consider more innovative methods of delivery of products and BIM is likely to be one of the catalysis to assist in this change. Our report which analysis data from previous years, show that our profession is moving in the right direction to meet these challenges. The results of our most recent survey show how far we have come in four years which identifies Qs’s level of understanding and current adoption levels of BIM. The survey was carried out to gain an insight into current knowledge levels and attitudes of the QS members in relation to BIM, as well as identifying the key areas which members feel should be addressed in order to increase the use of BIM by the QS profession. Responses to this survey were received from 121 SCSI Quantity Surveying members.

26%

62% of respondents are working for a firm who have either already implemented BIM or plan to formally implement BIM. Only 13% of respondents’ will not adopt BIM which is a 3% decrease from 2013.

Level 2 BIM projects This question looked at the respondent’s current or potential involvement in a BIM Level 2 project. Chart 7: Do you see yourself working on BIM Level 2 project soon?

25% 25%

I don't see myself being involved in a Level 2 BIM project

30% of respondents are currently working on, or will be working on, a BIM Level 2 project within the next year. An additional 25% see themselves working on a BIM Level 2 project in the next 1-2 years, while 25% believe it will be beyond 2 years before they will be working on a Level 2 BIM project.

Summary Results within this section illustrate the growing use of BIM within the Irish construction industry and the QS profession. Most companies are planning to adopt BIM while the majority (55%) of QSs see themselves working on a Level 2 BIM project within the next 2 years. This is a positive outlook for the QS adoption of BIM and illustrates the demand there will be for training and guidance in the near future. 10

Training and Software BIM Training Q. Does your company have QSs trained to use BIM to complete QS tasks (eg. Quantity Take-off) Chart 8: Does you company have QSs trained to use BIM to complete QS tasks (eg. Quantity Take-off)

Yes

50%

50%

No

50% of respondent’s work within companies that have QSs trained to use BIM to complete QS tasks such as take off.

BIM Software Q. Does your company have software which facilitates the use of BIM models for the QS? (eg. Visualisation or BIM Quantity Take-off) Chart 9: Does your company have software which facilitates the use of BIM models for the QS? (eg. Visualisation or BIM Quantity Take-off)

35% Yes No

65%

65% of respondent’s work within companies that have software which facilitates the use of BIM models for the QS. When compared to the previous question, this shows that while companies have the software, they do not have the employees to use the software. This shows a need for increased QS training in using BIM.

Chartered Quantity Surveyors’ Perspective on Building Information Modelling

Benefits and Barriers to using BIM Q. Do you believe BIM improves the accuracy of quantity take off for the QS? Chart 10: Do you believe BIM improves the accuracy of quantity take off for the QS?

18%

Yes No

82%

The majority of respondents believe that BIM can offer improved accuracy in QS take off of quantities. Some respondents felt that clear areas (Floors, walls and ceilings) can be measured with greater accuracy, as well as complicated structures or façades which may not be as easily measured from 2D drawings. However, the inclusion of extra over items such as deflection and connection details may not be modelled and will still require the knowledge and experience of the QS to include these within their measure. Accuracy also depends on the level of information designed within a model and the quality of the model design. Input and feedback from the QS when the model is being created can be crucial in insuring the correct information is included within the model for accurate take off.

Q. Do you believe BIM increases the speed at which you can complete quantity take off? Chart 11: Do you believe BIM increases the speed at which you can complete quantity take off?

11%

Yes No

89%

BIM can also improve the speed at which take off can be carried out manually, and more so, through the use of automated take-off, however the verification and cross-checking of quantities will now become increasingly important to confirm the accuracy of quantities from a model. 12

Chartered Quantity Surveyors’ Perspective on Building Information Modelling

Benefits to the QS This question allowed respondents to rank on a scale of 1 - 5 what they felt are the biggest benefits for a QS using BIM. The graph below shows the average ranking of each benefit.

Number of respondents

Chart 12: What do you see as the benefits of BIM for the QS?

Increased Increased Improved Increased Greater 5D BIM & Enhanced Gives a firm a speed of accuracy accuracy accuracy visualisation Live Cost QS role competitive Plans QTO of QTO of design edge information

The results of this question show that increased speed and accuracy of measurement in BIM are key benefits to the QS. As a design change in a BIM model is reflected in all views and throughout the model information, the consistency of design information is also beneficial to the QS. It is important to understand how increased efficiency and speed in measuring can enhance the role of the QS as opposed to threatening it. Time saved in measuring can allow the QS to provide additional value adding services such as Value Engineering, Life Cycle Costing and Carbon Costing.

Chartered Quantity Surveyors’ Perspective on Building Information Modelling

Barriers to BIM adoption The results above highlight the many benefits to the QS in using BIM. It was therefore important to investigate the key reasons that more Quantity Surveyors in Ireland are not using BIM. Again, respondents were required to rank their answers. Chart 13: Which of the following reasons do you believe are barriers to the QS adopting BIM in Ireland?

Uncertainty of Legal implications/liability when using BIM (eg.… Traditional procurement does not lend itself easily to using BIM Clients not requesting BIM on projects Design Information in a BIM model not being structured to… Lack of BIM standards in Ireland Lack of BIM guidance notes Cost of BIM training Cost of BIM software Lack of BIM understanding/skills 0% Strongly Agree

20% Neither

40%

60%

100%

120%

Disagree

Respondents strongly feel that design information within models not being structured correctly or, poorly designed models deter the QS from using a BIM model in carrying out their role. As mentioned above, QS input and feedback into model design from an early stage can help improve the design of a model to benefit the QS. Responses to this question also reflect a lack of understanding and skills in BIM amongst the QS profession in Ireland which must be addressed to allow an increase in the number of Quantity Surveyors using BIM.

14

Chartered Quantity Surveyors’ Perspective on Building Information Modelling

Increasing the use of BIM by the QS Chart 14: Which of the following do you think are important actions to increase the use of BIM by QSs?

Guidance for Designers on the QS requirements in BIM… Development of adoption of BIM standards for Ireland Government mandating of BIM Level 2 on projects... Provide Guidance Notes and talks by the SCSI for the QS Make BIM a key part of QS college courses Provide affordable software or grants for purchasing… Provide more BIM training courses for the QS Provide grants for upskilling/training in BIM 0% Very Important

100%

120%

Not Important

The majority of respondents believe it is very important that BIM is introduced as a key part of QS college courses in Ireland. This is echoed by respondents who also feel that more BIM training courses should be provided for the QS. The development of guidance notes for designers on the QS requirements in BIM models was also viewed as an important action to be undertaken. The SCSI QS BIM Working group will use results of this question, and the survey as whole, to insure that the correct steps are taken to help increase the understanding and adoption of BIM by the Quantity Surveying profession in Ireland.

15

Chartered Quantity Surveyors’ Perspective on Building Information Modelling

Recommendations/SCSI Actions The results of this survey clearly point towards an increase in the adoption of BIM by the QS’s in Ireland, and the plan for further adoption in the near future. Those who have already implemented BIM in their work have experienced its benefits, however many are still struggling to overcome the barriers to adoption. The SCSI therefore, plan to offer the required support, training and guidance for Quantity Surveyors, based on the feedback obtained through this survey, in order to help them successfully adopt and utilise BIM within their work practice through the following actions; 1. Provide support and guidance to members through the QS BIM Working Group members (Contact Details below) 2. Publish Guidance Notes on BIM for the Quantity Surveyor 3. Develop Guidance Notes for Designers on QS requirements in BIM models at various project stages 4. Organise CPD talks to explain the benefits and means to overcome barriers to adopting BIM 5. Arrange Training Seminars and Workshops on BIM The SCSI/BIM Working Group will develop a BIM Strategy, setting out key goals and defined objectives in relation to increasing knowledge and use of BIM amongst QS members over the next 2 years.
