The responsibilities include a range of tasks that require analytical and practical skills, ensuring that costs are managed effectively and that the project progresses within its defined parameters.

One of the core responsibilities of a QS on a project involves quantity takeoffs and vendor evaluation. This process encompasses the extraction of precise material and labour requirements from technical drawings. By systematically analysing these specifications, the QS can prepare accurate estimates that directly inform procurement strategies. Furthermore, evaluating vendor quotations is essential; it allows the QS to ascertain the best value propositions without compromising on quality, thereby ensuring financial efficacy throughout the project’s lifecycle (Yap et al., 2021). Rigorous assessment helps minimise cost overruns by leveraging competitive pricing while maintaining standards (AAG & Latief, 2023).

Subsequently, the drafting of subcontract and procurement agreements becomes crucial. Clear contracts delineating deliverables, timelines, and payment terms are vital to mitigating the risks of disputes among stakeholders (Victar et al., 2022). An effective QS delivers contracts that not only protect the project’s interests but also promote transparency and accountability between parties involved (Victar et al., 2023). Contractual clarity extends to the as-built measurements, where the QS is responsible for validating completed works against initial design specifications. Validation ensures that all financial claims reflect the actual work completed, thereby preventing discrepancies that could lead to payment issues down the line (Akomea-Frimpong et al., 2024).

Moreover, developing accurate cost estimates and forecasts is foundational within the QS’s role, supporting financial planning from the feasibility stage through to project closure. Such forecasts must be dynamic, taking into account market fluctuations and incorporating contingency allowances for identified risks (“Innovative Changes in Quantity Surveying Practice through BIM, Big Data, Artificial Intelligence and Machine Learning”, 2020). A forward-looking perspective bolsters the project’s financial strategy and allows for informed decision-making regarding resource allocation (Theddy & Pranoto, 2024).

A significant aspect of financial oversight during project execution involves claims verification. The process ensures that all invoices submitted by subcontractors and suppliers accurately reflect the progress made on-site, thus protecting the project’s financial integrity before any payments are authorised (Alimi et al., 2021). Inevitably, disputes could arise; hence, the QS must have a methodical approach to verify these claims against documented progress and quality standards (et al., 2023).

Additionally, Variation Order Management highlights the QS’s capacity to adapt to changing project requirements and client requests. The QS coordinates with various stakeholders, particularly consultants, to assess and approve changes that impact the project’s budget or timeline without causing disruptions (Siahaan et al., 2024). function demands an agile mindset and the ability to negotiate and communicate variances effectively, which ensures continued project alignment with initial objectives (Park et al., 2020).

As these responsibilities unfold, the demand for speed and precision has intensified. Hence, the adoption of modern technologies plays a crucial role in the QS’s effectiveness. AI-powered construction technologies augment traditional methodologies, offering enhanced data accuracy and efficiency in tasks such as cost estimation and project monitoring (Victar et al., 2023). These technologies not only accelerate processes but also improve the reliability of financial analyses, supporting the QS in navigating the complexities of mega infrastructure projects.

In conclusion, the role of the quantity surveyor in the Jakarta WWTP project is strategically vital for delivering a successful outcome. Their involvement spans from early planning through to execution, integrating cost management, contractual negotiation, and technological innovation to ensure that every aspect of the project is meticulously controlled. The QS not only ensures compliance with financial constraints but also enhances overall project delivery by maintaining focus on quality and efficiency throughout the life of the project.

Challenges in Conventional QS Practice

In the realm of traditional Quantity Surveying (QS) practice, several persistent challenges hinder efficiency and effectiveness. These challenges include data fragmentation, manual repetition, reactive risk management, and slow collaboration among stakeholders. Each of these factors contributes to increased project risks, reduced productivity, and missed opportunities for value optimisation, highlighting critical areas where improvements are necessary.

Data fragmentation is a significant challenge within conventional QS workflows. Information related to construction projects is often scattered across various platforms, including emails, technical drawings, paper files, and siloed databases. Fragmentation leads to difficulties in information retrieval, which can be slow and error-prone (Nawi et al., 2014). The implications of the issue are severe, as delayed access to crucial information can impede decision-making processes and ultimately affect project timelines and budgets (Tanga et al., 2022).

Furthermore, the reliance on manual methods for measuring quantities, counting symbols on drawings, and cross-checking invoices results in manual repetition that consumes considerable time and resources. Manual oversight can cause delays in processes that require prompt feedback and corrective actions. As a result, the overall efficiency of the QS function may diminish, complicating the timely delivery of projects (Ingle et al., 2020). The repetitive nature of these tasks can also lead to human error, further exacerbating the likelihood of inaccuracies in cost estimation and reporting (Nawi et al., 2014).

Reactive risk management is another challenge facing traditional QS practice. In conventional workflows, issues such as cost overruns and contractual disputes are often identified only after adverse consequences have occurred. A reactive approach to risk management is increasingly recognised as inadequate in an environment where rapid changes in project scope are common (AbdulRahman et al., 2015). Suboptimal risk identification processes can lead to adverse outcomes for projects, necessitating a shift toward more proactive methodologies that emphasise early detection and resolution of potential issues (Basir et al., 2023).

Finally, slow collaboration among various project stakeholders, including QS teams, engineers, and contractors, results from the absence of a unified data platform. Without real-time access to shared documents and updated information, teams may operate on conflicting versions of project data, leading to inconsistencies and misaligned objectives (Eze et al., 2019). The fragmented communication channels not only impede effective coordination but also foster an environment ripe for misunderstandings and mismanagement, thereby increasing project risks further (Latiffi & Zulkiffli, 2022).

In conclusion, the integration of advanced technologies and collaborative tools presents significant potential for addressing these traditional challenges in QS practice. By adopting integrated management information systems and digital platforms, the construction industry can streamline data processes, improve risk management, and foster better communication among stakeholders. Transitioning from fragmented practices to a more cohesive and collaborative model is paramount for optimising project outcomes.
