Abstract
Collaboration is essential to the success of construction projects and a defined collaborative process is one of the key elements of a successful relationship in construction. Although the consultant and contractor are key stakeholders in construction yet it is not being proven how their relationship affect projects in Nigeria’s construction industry. Therefore, this study evaluates the effect of collaboration on the success of construction projects. Quantitative study was conducted and primary data were collected through structured questionnaire on collaborative processes, success factors of projects in relation to collaboration and the impact of consultant-contractor collaboration on project success. The data collected from 135 consulting and construction firms in Lagos, Nigeria was analyzed using frequency distribution, mean score, ANOVA and multiple regression. The finding of the study revealed that the consultants and contractors are involved in the collaboration processes though they are mostly involved clear roles and responsibility, information sharing, cooperation and coordination, improved communication and collaborative governance. Also, the finding revealed that efficient coordination and dedicated team are the collaborative factors that contribute more to project success. Conclusively, the finding depicts that effective and efficient collaboration between consultant and contractor significantly impact the success of construction projects with R<sup>2</sup> as 0.7403. The implication of the study is that project actors should continually accept and practice all levels and processes of collaboration and so as achieve a successful project delivery and pave way for the implementation of digital collaboration in Nigeria’s construction industry.

Summary
Collaboration is crucial for the successful completion of construction projects within time and budget [1, 21]. Collaboration is a relationship between two or more organizations to collectively address problems and deliver results. Irrespective of types; forms and characteristics, collaboration is described as a mutual agreement between two or more partners through communication and networking so as to solve a problem [22, 11]. Collaboration is built on commitment for mutual relationships, shared responsibility and goals which requires comprehensive planning and well defined communication channels. Collaboration is effective when it involves the exchange of information, sharing of resources, engaging all members for mutual benefit [19] and designing a rigorous process for success and positive change [34].
