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 Notice of Intent to Lien (NOI)?
A notice of intent to lien (NOI)—also called a notice of non-payment or intent notice—is a formal legal document warning a property owner, general contractor, or lender that a subcontractor or supplier plans to file a mechanics lien if an unpaid balance isn't settled within a set number of days.
Acting as a final warning before taking legal action, an NOI often resolves payment disputes quickly because property owners cannot sell, transfer, or refinance a property with a mechanics lien attached. While only legally required in certain states (full list here), sending an NOI is a low-cost, highly effective A/R strategy for collecting past-due funds without going through the formal lien filing process.
Notice of Intent vs. Preliminary Notice:
- Preliminary Notice: Sent at the start of a project to preserve your baseline right to file a lien if needed later.
- Notice of Intent to Lien (NOI): Sent after a payment is significantly overdue as a final deadline demand before officially recording the mechanics lien.
How Siteline Helps:
Every state has different lien rules, timelines, and required forms, making it easy to miss crucial notice deadlines and accidentally forfeit your lien rights. Siteline tracks state-specific lien deadlines across all your projects behind the scenes. When an account becomes severely past due, Siteline helps you instantly generate state-compliant lien notices using project data and send them via certified mail—so you preserve your leverage and protect your right to get paid.
What is a Transmittal?
A transmittal in construction is a formal document that accompanies the delivery of project materials like drawings, specifications, reports, or samples. It’s like a receipt that creates an official record of what was sent, when it was sent, and who received it.
Transmittals typically include document details, revision numbers, dates, and any special instructions about enclosed materials. They’re essential for keeping everyone—from the field to the back office—on the same page throughout the project.
Just like transmittals ensure project documents don't get lost in the shuffle, Siteline brings that same level of transparency to subcontractor billing workflows. It gives subcontractors a centralized solution for managing pay applications, tracking compliance and payments, and spotting cash flow holdups before they derail operations.

What is Credit?
Credit in the construction industry refers to the financial trust extended to a company or contractor, enabling them to procure goods or services with the understanding that they will pay for these in the future, typically with added interest. Credit is instrumental in this industry, as it often involves huge capital investments upfront, long before the revenue from the completed project is realized. A company's creditworthiness or ability to repay, is a determining factor in receiving credit. Construction companies frequently use lines of credit for purchasing equipment, hiring labor, buying supplies, and meeting emergency expenses. Moreover, credit facilitates smooth cash flow, allowing construction projects to progress without financial hiccups.
