Purpose

The purpose of the work presented here is to assess the cost management practices of civil engineering organisations in Nigeria, with an overall aim of developing a generic cost management process map. The first objective is to compare existing frameworks theoretically to highlight their strengths and weaknesses. The second objective is to use the findings of the first objective to assess or benchmark the developed process map obtained from the multiple cases. The third objective is to compare the generic process map with the traditional building cost management process map to evaluate the strengths and shortcomings of the generic process map, which resulted in conclusions and recommendations made at the end of the research.

Design/methodology/approach

Data for the work was collected via semi-structured interviews, review of literature and official documents of the civil engineering organisations visited. To achieve the stated objectives, comparative analysis technique was used to compare existing frameworks on cost management to obtain the basis to benchmark the generic process map. The single case narrative technique was used to present each case; and the cross-case synthesis technique was used to present the multiple cases on each cost management process examined. Then, process maps were deployed to represent the homogeneous sets of civil engineering organisations, out of which the generic process map was developed. Comparative analysis was again deployed to compare the generic process map with the traditional building process map of cost management practice to evaluate the findings.

Findings

It was found out that the generic civil engineering process map is not as detailed and effective as the building process map in providing best value for money, accurate early cost estimates, accurate cost certainty and post-contract cost control.

Originality/value

This research study provides an industrial impetus to push for the involvement of more quantity surveyors (QS) as cost management process owners in the procurement of civil engineering projects in Nigeria, hence encouraging government’s efforts in the enforcement of more accurate project cost estimates and promoting the QS’s project-specific advice on capital, operational, maintenance and life cycle costs.

尼日利亚翁多州土木工程（项目采购）组织成本管理实践的评估

目的

此处介绍的工作的目的是评估尼日利亚土木工程组织的成本管理实践，总体目标是制定通用成本管理流程图。第一个目标是从理论上比较现有框架，以突出它们的优势和劣势。第二个目标是使用第一个目标的结果来评估或基准化从多个案例中获得的开发过程图。第三个目标是将通用流程图与传统的建筑成本管理流程图进行比较，以评估通用流程图的优缺点，从而在研究结束时得出结论和建议。

设计/方法/方法

这项工作的数据是通过半结构化访谈、文献回顾和访问的土木工程组织的官方文件收集的。为了实现既定目标，比较分析技术被用来比较现有的成本管理框架，以获得对通用流程图进行基准测试的基础。使用单一案例叙述技术来呈现每个案例；并使用跨案例综合技术来呈现每个检查的成本管理流程的多个案例。然后，部署流程图来表示土木工程组织的同质集合，并从中开发出通用流程图。再次部署比较分析，将通用流程图与成本管理实践的传统构建流程图进行比较，以评估结果。

发现

结果发现，在提供最佳性价比、准确的早期成本估算、准确的成本确定性和合同后成本控制方面，通用土木工程流程图不如建筑流程图详细和有效。

原创性/价值

这项研究为推动更多工料测量师 (QS) 作为成本管理流程所有者参与尼日利亚土木工程项目的采购提供了行业动力，从而鼓励政府努力执行更准确的项目成本估算并促进QS 针对资本、运营、维护和生命周期成本的项目特定建议。
