Conducting a feasibility study is a critical early phase in construction project management, particularly for quantity surveyors tasked with assessing whether a proposed project is viable from financial, technical, and regulatory perspectives. This chapter focuses on essential activities such as site visits and the determination of investment costs, which are foundational for making informed recommendations. In Kenya, where land availability, construction materials, and financing conditions vary widely by region, a thorough feasibility study ensures that risks are minimized and projects align with stakeholders' expectations and budgets.

1.1 Site Visits

1.1.1 Purpose of Site Visits

Site visits serve multiple purposes in the feasibility phase. They enable quantity surveyors to verify site boundaries and topography, which affect earthworks and foundation design. Additionally, visits help identify existing infrastructure such as roads, utilities, and drainage, which influence connection costs and project logistics. For instance, at a county government office expansion in Kisumu, a site visit revealed the need for additional drainage works not captured in initial plans, impacting the overall cost estimate. Site visits also facilitate early engagement with local authorities and communities to understand potential regulatory or social constraints.

1.1.2 Preparation for Site Visits

Effective site visits require meticulous preparation. Quantity surveyors must review all available documentation, including architectural drawings, previous site reports, and land titles, before visiting. They should develop a checklist tailored to project specifics, covering aspects like soil conditions, access routes, and proximity to suppliers. Engaging multidisciplinary teams, including architects and engineers, during visits ensures comprehensive data collection. For example, during a feasibility study for a hotel project in Mombasa, collaboration between quantity surveyors and geotechnical engineers during site visits helped anticipate foundation challenges early.

1.1.3 Data Collection Techniques During Site Visits

Collecting accurate data on site involves both qualitative and quantitative methods. Quantity surveyors take measurements of key site dimensions and elevations using tools such as measuring tapes and GPS devices. They also document site conditions through photographs and notes, capturing environmental factors that may affect construction. Interviews with local residents or officials can provide information on historical site use or potential hazards. For projects in Nairobi's informal settlements, such community engagement has been crucial for understanding access difficulties and security concerns.

1.1.4 Reporting and Utilization of Site Visit Findings

The findings from site visits must be systematically recorded and integrated into feasibility reports. Quantity surveyors prepare detailed site visit reports highlighting observations, potential risks, and recommendations. These reports guide cost estimations, risk assessments, and design adjustments. For example, a site visit report for a retail complex in Nakuru prompted the inclusion of additional site preparation costs due to rocky terrain, which was critical for accurate budgeting. Clear documentation also facilitates communication with clients and stakeholders, ensuring all parties understand site-related constraints.

Chapter Summary

This chapter covered the essential steps involved in conducting a feasibility study for construction projects, beginning with the importance of thorough site visits to assess physical conditions and environmental factors. It then detailed how to determine the total investment cost, including breakdowns of construction expenses, land acquisition costs, and interest considerations. The chapter introduced PESTEL analysis as a framework for evaluating political, economic, social, technological, environmental, and legal influences on the project. Preparation of the feasibility study was explained as a comprehensive process that consolidates all gathered data and analyses into a coherent report. Various types of feasibility studies were examined, such as financial, technical, environmental, economic, social or political, market, and schedule feasibility, each addressing different project viability aspects. The role of artificial intelligence in enhancing feasibility studies was explored, highlighting its applications in market research, data collection, demand forecasting, revenue projection, and resource optimization. Finally, the chapter discussed scenario planning as a strategic tool to anticipate potential future developments and uncertainties affecting the project’s success.
