What is Net D?
Net D, in the context of the construction industry, refers to the "net deliverable" square footage or area of a constructed property. It applies to the actual usable space that remains after the subtraction of communal areas such as shared hallways, staircases, and residential utilities from the gross square footage. In commercial real estate, it typically excludes areas reserved for mechanical systems, structural elements, elevator shafts, and similar components. This figure is critical as it impacts the leasing or selling value of a property and also informs space allocation, cost assessment, and planning considerations during a construction project. Therefore, understanding Net D is key to optimizing building layouts and the planning of space allocations within any construction project.

What are Liquidated Damages?
Liquidated damages in the construction industry are a pre-agreed sum specified in a construction contract, which the contractor will pay to the client in the event of a breach of contract, typically when there are delays in completion. This contract clause serves as a protection mechanism for the client, giving an estimate of the potential loss they might incur due to the delay. However, liquidated damages must be a genuine pre-estimate of loss, not a penalty. They are not intended to be a punishment, but a compensation for the client's actual anticipated loss. This approach mitigates the risks and provides predictability for both parties in a construction project. One party cannot claim more than the contracted liquidated damages. They bring certainty to the potentially complex process of calculating actual damages in construction delays, thus fostering an efficient dispute resolution.
What is Overbilling?
Overbilling (or billing in excess of costs) occurs when you’ve invoiced your client for more work than you’ve actually completed or incurred costs for. In other words, it represents getting paid ahead of your work schedule.
Here’s how it works: If you’re a concrete subcontractor on a $100,000 job and you bill 50% upfront ($50,000) but have only completed $30,000 worth of work, that $20,000 difference is your billings in excess of costs. You owe your client that work, and until you complete it, that $20,000 remains as a liability on your balance sheet.
For subcontractors, understanding billing in excess of costs is essential because it can be a strategic cash flow tool when used carefully. For example, when bidding on a job, you can be smart about how you structure your schedule of values (SOV)—breaking work down into more detailed line items that allow earlier billing. However, this strategy requires regular monitoring to ensure:
- Your billing somewhat aligns with your actual percentage complete, and
- The remaining contract value will still cover your remaining costs.
The biggest risk of overbilling is thinking your margins look better than they are, simply because you’re collecting cash faster. Surety companies and lenders also scrutinize overbillings closely, as excessive amounts can signal poor project management or potential cash flow problems down the road.
With Siteline, you can easily track whether you’re billing in excess of your costs by pulling your month-to-month incurred costs and comparing them against your billing progress. This real-time visibility helps ensure you’re billing appropriately while maintaining realistic profitability expectations.

What is a draw request?
A draw request (or construction draw) is a formal demand for payment submitted by a contractor or subcontractor to a lender, project owner, or general contractor for work completed during a specific phase of a project.
Submitted periodically alongside a schedule of values, a draw request details completed labor, materials installed, and stored items. Once submitted, it typically triggers a bank draw inspection to verify on-site progress before funds are released, ensuring project financing directly aligns with actual work completed.
How Siteline Helps:
Siteline accelerates the entire draw request workflow. Trade contractors can quickly assemble accurate pay applications, compile required backup documentation, and collect lien waivers in one place so draw requests get approved and paid without administrative back-and-forth.
