What is a Limited Notice to Proceed (LNTP)?

An LNTP is a written authorization that lets a contractor start a specific, bounded slice of work before the full contract is signed. Instead of waiting for the entire agreement to be executed, the owner authorizes defined early activities, commonly long-lead material procurement, submittals, or mobilization, usually up to a stated dollar limit. It exists because some work cannot wait: if a piece of equipment has a six-month lead time, ordering it on day one protects the schedule even though the full contract is still being negotiated. The LNTP caps the owner's commitment to the limited scope and dollar amount it names, so it is a controlled early start, not a blank check.

Is mobilization or a down payment just free money up front?

No. Mobilization money is payment for real start-up costs that occur before any permanent work is installed: moving equipment onto the site, setting up the field office, bonds and insurance, and initial procurement. It is legitimate because those costs are genuinely incurred early, but it is not a gift. Paid ahead of installed work, a true advance or down payment is almost always recovered over later billings so cumulative payments stay tied to work in place; a mobilization line carried on the schedule of values is instead earned down as that start-up work is performed. Either way the owner is protected against paying ahead of the work. A mobilization line on the schedule of values that is set far above true start-up cost is a form of front-loading, which owners and architects scrutinize and often reject.

How is the up-front advance recovered?

Through one of a few mechanisms, all aimed at keeping payment aligned with progress. The advance may be amortized, recovered in equal deductions across a set number of progress payments, or it may be folded into retention, so the held-back retainage offsets the early overpayment until work in place catches up. In some contracts the mobilization line on the schedule of values is simply earned down as that work is completed. Whichever method the contract uses, the goal is the same: the contractor gets the cash it needs to start, but cumulative billing never gets too far ahead of the work actually in the ground, so the owner is not exposed.

LNTP &Mobilization

Some work cannot wait for the ink to dry. A limited notice starts the long-lead items, and the money to mobilize is advanced, then recovered so billing never outruns the build.

Definition

A Limited Notice to Proceed (LNTP) authorizes a contractor to begin a defined, limited scope, such as long-lead procurement or mobilization, before the full contract is executed. Mobilization, or a down payment, is the up-front money to get started: moving in, the trailer, bonds, initial procurement. Because both are paid ahead of installed work, the advance is typically recovered across progress billings or folded into retention so it never outruns work in place.

Advanced, then recovered

On our $12.0M project, $600K is advanced at LNTP to mobilize and order long-lead items, then clawed back across the early progress billings until cumulative payment is tied to work in place.

A limited start, not a blank check

An LNTP is bounded by scope and dollars. It buys schedule on the items that cannot wait, without committing the owner to the whole contract early.

	Limited NTP (LNTP)	Full Notice to Proceed
Authorizes	A defined early slice (long-lead, mobilization)	The entire contract scope
Owner commitment	Capped at a stated dollar limit	The full contract sum
When	Before the full contract is executed	On contract execution
Why	Protect the schedule on items that cannot wait	Begin the balance of the work

How POD reads the advance

When POD reads a pay application, it recognizes an up-front mobilization, down-payment, or limited-notice line and folds it into its retention tracking, so the early advance is reflected against work in place rather than counted as ordinary earned value. That keeps cumulative billing honest on the periods where an advance would otherwise make progress look further along than it is. POD does not issue your LNTP or set the recovery schedule your contract specifies; it reads the pay-app the way the contract intends, so the advance and its recovery are both visible in the numbers.

Frequently asked questions

The advance lives on the pay app

Mobilization is billed, recovered, and often offset by retainage, all on the same pay application that carries the rest of the work.
