Abstract
This study examined the extent of building information modelling (BIM) usage among
construction professionals, determined the interface problems in construction project stages among
professionals and investigated the impact of BIM usage on professional’s interface at stages of
construction projects in Lagos State, Nigeria. These were with a view to providing information
that could enhance project delivery.
Primary data were used for this study and obtained through structured questionnaire. The
target population was construction professionals who had substantial knowledge of BIM usage
and who had experienced interface problems at the design and construction stages of projects in
Lagos State. A total of two hundred and sixty (260) copies of completed questionnaire were
retrieved through online and physical administration using snowball sampling technique for
selection of respondents. Data were analysed using frequency, percentages, exploratory factor
analysis, confirmatory factor analysis and structural equation modelling.
Findings revealed that more than 70% of the respondents had less than six years’
experience with BIM usage, 36.5% of the respondents had employed BIM for private projects,
48.5% for public-private projects and majority of the construction professionals use BIM mostly
for building projects (90%) and design-build procurement method (57.2%). Over 60% of
construction professionals had either very low, low or fair level of competency in respect of BIM
usage. On the proficiency level of BIM usage, about 86.5% among the professional members were
either skilled or semi-skilled. The overall satisfaction level in using BIM for project work was
74.2% among the project members which shows that a majority of them were satisfied with BIM
usage. The major interface problems at the design stage in the study are badly written contract
(C15); excessive amendments when changes occur in designs (C16) (DIP5=0.794); lack of stipulated data (C4) (DIP1=0.744); and design complexity (C9) (DIP4=0.743). However, the
major interface problems at the construction stage are change order (C29) (CIP4=0.814);
inadequate specialised quality-control team (C31) (CIP1=0.798); and poor quality of construction
(C21) (CIP2=0.797). The impact of BIM on professionals’ interface at the design stage are
producing tools for reporting task completion, quality value and mistakes of the design team (ID5)
(IDS1=0.836); automatic low-level of amendments whenever modification occurs in design
(ID14) (IDS2=0.794); and improve design quality (ID8) (IDS3=0.771). The impact at the
construction stage includes enhanced site utilisation, space coordination and production data (IC4)
(ICS3=0.788); enhanced quality control process on site (IC9) (ICS1=0.787); and minimised
interface conflict through integration of construction simulation (IC18) (ICS2=0.774).
