Quantity Survey
What is a Quantity Survey?
A quantity survey, also known as a bill of quantities (BOQ), in the construction industry is a detailed analysis and estimation of all parts, materials, and costs associated with a construction project. This process is carried out by a professional known as a quantity surveyor. The surveyor evaluates the quantities of materials needed, required labor, groundwork needed, and the overall time frame of the project. They also consider other variables to provide an accurate cost analysis, like the complexity of the project, the potential risks, and the market conditions.
The main purpose of a quantity survey is to:
- Accurately estimate the cost of a construction project: By quantifying all the required materials and resources, the quantity survey helps contractors and clients estimate the total cost of the project accurately. For subcontractors specifically, quantity surveys are used to price out the cost of their portion of the work, ensuring they quote competitively while accounting for all the necessary materials and labor.
- Facilitate bidding and tendering: The quantity survey provides a standardized format for subcontractors to prepare their bids based on the same information, ensuring fair competition during the tendering process.
- Control project costs: During the construction phase, the quantity survey serves as a reference point for monitoring and controlling costs, as actual quantities used can (and should) be compared against estimated quantities.
- Manage changes: If the original scope of work changes or varies, the quantity survey serves as a baseline for evaluating and negotiating the cost implications of those changes.
A quantity survey is essential for subcontractors to accurately estimate costs, plan resources, and manage project scope. While not directly integrated, solutions like Siteline allow subcontractors to leverage quantity survey data to streamline their billing processes.
- Subcontractors can generate payment applications in Siteline that reflect completed work items and quantities from the survey, minimizing disputes.
- Some clients use Siteline's billing and A/R reports to help quantity surveyors and estimators account for contractors with longer payment cycles. They can either increase bids for those contractors to offset delays or revise terms to penalize late payments.
- Siteline also seamlessly tracks change orders, enabling subcontractors to easily update payment applications and lien waivers when project scope changes, keeping everything documented and billed accurately.
By bridging the gap between contracted scope and actual billing, Siteline enables subcontractors to focus on execution while ensuring prompt, accurate payments. Experience the power of efficient payment management tailored for subcontractors. Schedule a demo of Siteline today.

What is Certified Payroll?
Certified Payroll is a specific type of payroll process required for any contractor or subcontractor working on federally funded or assisted construction projects under the Davis-Bacon Act. It is a federal compliance requirement to ensure employees are paid prevailing local wage rates and benefits. Certified Payroll records include the worker's name, their classification, hourly rates of wages paid, daily and weekly hours worked, deductions made, and actual wage paid. It provides transparency for regulators, ensuring fair wages for work conducted. This mandatory weekly submission acts as an assertive step in suppressing wage theft in the construction industry.
What is a Claim?
In the construction industry, a claim refers to a request or demand for compensation or remediation rights. Such claims often emerge for varying reasons, including unexpected project situations, changes in project scope, unforeseen conditions, or disputes over contract interpretations. For instance, if a construction team encounters an unexpected geological impediment on a site, delaying the project, they might file a claim to recover the costs caused by this delay. These claims are typically addressed in detail within the terms and conditions of construction contracts and might have to be resolved in court or through arbitration if the two parties cannot reach an agreement. It is imperative for every party involved in any construction project to be aware of potential claims to understand their rights and obligations. Therefore, effective claim management is key to successful construction project execution.
What is a Request for Information (RFI)?
A Request for Information (RFI) in the construction industry is a formal process through which a party involved in a construction project request details about a document or a process. It acts as a vital communication tool between multiple project parties such as the general contractor, subcontractor, and the design team. This is generally used to resolve information gaps, make decisions or track project changes. The main purpose of an RFI in construction is to eliminate any ambiguity, introduce a control mechanism, avoid unrealistic project expectations and ensure that all participants have a clear understanding of the project. It assists in minimizing project risks and avoids potential disputes related to design issues, cost overruns or schedule delays. It's an essential element in maintaining transparency, effective communication and collaboration within a construction project.
