Role of construction professionals such as architects, engineering consultants, builders, quantity surveyors in monitoring a construction project is discussed.
A construction project is a product of different information and designs from different professionals. If these information and designs are to be adhered to, the presence of their producers and designers are required.

Role of ArchitectAccording to Bamisile (2004), the architect should be visiting site periodically for inspections to ensure that in general, the work being carried out on site is in compliance with architectural designs and specifications.
Role of Engineering ConsultantsBamisile (2004) noted that during the construction phase, engineers (geotechnical, structural, electrical and mechanical) should visit the site regularly for inspections to ensure that in general, is in compliance with their engineering drawings, schedules and specification. A Structural Engineer should be concerned with the monitoring and ensuring that the design (structural) performance criteria are met in the construction methods and materials. Similarly, the mechanical and electrical engineer should monitor the type and ways of installing mechanical and electrical installations so as to ensure that it complies with their designs and specifications.
Role of the BuilderThe core function of a builder in any construction project is Building Production Management. An integral part of management is monitoring. A builder should be concerned with monitoring and evaluating the construction project. He should be able to apply the different monitoring techniques to achieve the objectives. A builder needs to be fully aware and conversant with the different construction professionals and their corresponding contract documents so that their implementation can be properly monitored.
Role of the Quantity SurveyorA Quantity Surveyor is concerned with the quantities and cost associated in a construction project. As a cost expert, the Quantity Surveyor monitors the cost of every aspects of a construction project. He does this so that the total cost of production does not exceed the estimated cost.
Areas of Monitoring of the Construction ProjectA construction project is considered successful if it meets defined needs to the required standard (quality) within the time and cost budget. These parameters – quality, cost and time are critical and should therefore be monitored as they define the success level of any construction project.
1. Construction QualityFor monitoring of quality to be effective, it must be measured against a standard. The Project Quality Management Plan serves as a standard against which the quality of a construction project can be measured. Quality in a construction project depends on a range of variables and involves much more than the simple parameters such as the visible standard of finishes, structural soundness, or making of components fit within close tolerances. The monitoring of quality should embrace all the aspects by which a construction project is judged including spatial arrangement, circulation, efficiency, aesthetics, flexibility as well as its functional ability as a climate modifier and as a suitable structure. Besides the Project Quality Management Plan, contract and job specifications also provide a criterion by which to assess and assure the quality of a construction project.
2. Construction CostFor control and monitoring purposes, the detailed cost estimate should be converted to a project budget, and the project budget is used subsequently as a guide for management. The detailed cost estimate should provide a baseline for the assessment of financial performance during a construction project. Expenses during the course of the project should be recorded in specific job cost accounts and this should be compared with the original detailed cost estimates. When the cost are within the detailed cost estimate, the cost and finance of a construction project is thought to be monitored and under control.
3. Construction TimeConstruction typically involves a deadline for work completion, so construction managers must force attention to time. More generally, a delay in construction represents additional costs due to late facility occupancy and other factors. The duration of activities must therefore be monitored and compared to expected durations so that the project is completed within the time required.
Monitoring Techniques in Construction ProjectsThe method of ensuring that an accurate check is kept upon progress in a construction project is very important, depending as it does upon frequent comparisons between work done and programme. Such comparisons can be made in a simple visual manner, so as to throw into prominence any divergence between the two by plotting the progress on the construction programme (Bamisile, 2004). According to Olorunoje et al (2004), monitoring tools will involve recording techniques such as the use of network diagrams like:
- Gantt chart
- Arrow diagram or critical path analysis
- Progress curves
