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 a Joint Check Agreement?
A Joint Check Agreement is a contractual agreement in the construction industry used to ensure all parties involved in a project get paid. This agreement involves primarily three parties - the property owner, general contractor, and subcontractor or material supplier. The property owner or general contractor issues a check payable to both the subcontractor and materials supplier, providing a layer of protection against mechanic's lien. This means both parties must endorse the check for it to be cashed, ensuring the funds are distributed appropriately. This way, it mitigates the risk of non-payment for subcontractors and suppliers. Additionally, it helps the owner or general contractor to ensure project progression without disputes or delays related to payment issues. However, details of the agreement, like the proportion of payment to each party, need to be clearly outlined to avoid potential conflicts.
What is a Cost Overrun?
A cost overrun, in the context of the construction industry, refers to the excess amount that needs to be spent over the initially agreed or budgeted cost for completing a particular project. It’s an unanticipated increase in costs that occurs due to various factors such as inaccurate estimation, changes in project scope, unforeseen challenges, or increase in material or labor costs. In essence, it’s when the actual cost of the project exceeds the estimated cost. It is critical to manage and minimize cost overruns as they can seriously impact the overall profitability and success of a construction project. Effective project management, regular monitoring, vigilant control measures, and contingency planning are some strategies to mitigate such cost overruns in construction projects.
What is Double-Entry Accounting?
Double-entry accounting is a system used extensively in the construction industry, where every financial transaction has equal and opposite effects in at least two different accounts. The objective is to ensure the sum of all debits always equals the sum of all credits, thereby maintaining balance in the books. For example, if a construction company purchases building materials, it records the transaction as a debit in the inventory account but a credit in the cash account. This system allows for easier financial analysis, error tracing, and fair representation of a company’s financial position. This method also manages the complexity of financial transactions in the construction industry, increasing financial reliability and providing valuable insights on company performance.
