This paper explores the benefits and barriers to partnering in quantity-surveying (QS) firms in Nigeria, and suggests projects and professional services best served by this practice. A mixed research design informs the identification of related concepts from extant literature and data collection from 132 registered members of the Nigerian Institute of Quantity Surveyors (NIQS) which were analyzed using statistical tools. The commitment of top management is found to be a key barrier to QS firm partnering. The facilitation of knowledge exchange and inclusivity is the most significant benefit. In this paper, feasibility studies, expert advice, and lifecycle costing are key services of QS firms that would benefit from partnering, and research findings also favor engineering projects as core projects in which QS firms should utilize partnering.This study presents project stakeholders with practical and efficient strategies to facilitate the implementation of partnering arrangements to execute construction projects and has considerable implications for the quantity-surveying practice because it recommends professional services and projects with greater viability for the partnering arrangement.

Today, several researches have been carried out in the area of sustainability with much emphasis being placed on the environmental dimension. Though this is good, a balance needs to be created between the environmental, economic and social sustainability dimensions. Bearing this in mind, the construction professionals are saddled with the responsibility of delivering sustainable construction projects using diverse tools. One of such tool is Value Management (VM). Hence, this research assessed the use of VM in delivering economically sustainable constructions. A case study approach was employed and the study revealed that VM has a great role to play in delivering economic sustainability in construction since both VM and Sustainability (the economic dimension) have a common goal which is; achieving value for money. Notable benefits of VM in providing economic sustainability in construction includes: reduction of overall cost while maintaining function through identification and removal of unnecessary materials and process and use of local materials to save cost of importation and transportation. The study therefore recommends the implementation of VM in building construction and presentation at various workshops and seminars in order to enhance sustainable construction development through VM practise.
