How to Plan Aggregate Deliveries for Large-Scale Construction Projects

When you’re running a large construction site, managing aggregate deliveries is one of those things that can quietly make or break your timeline. Get it right, and everything flows. Get it wrong, and you’re chasing delays, juggling storage, or watching mixers sit idle.

Planning bulk aggregate deliveries isn’t just about ordering X tonnes on a certain day. It’s about forecasting site needs, understanding lead times, and working with a supplier who knows how to keep pace with high-volume demand.

At Armstrongs, we work closely with contractors across highways, civils, and industrial builds to make sure materials turn up where and when they’re needed. Here’s how to keep your delivery schedule tight - and your site moving.

Understand your aggregate needs early

It sounds obvious, but too often delivery planning starts too late. As soon as your project is scoped, you should be identifying:

  • What aggregates you need (type, grading, volume)
  • When you need them (and in what sequence)
  • What storage or handling is required on site

Are you pouring structural concrete? Compacting sub-base? Building up drainage layers? Each use case will need different materials, and timings can overlap. Knowing this up front makes scheduling a whole lot easier.

Track materials by phase to avoid over-ordering

On large-scale projects, ordering too much too soon can choke your site. It takes up valuable space, increases handling costs, and risks contamination or waste. Instead, align your deliveries to specific phases: sub-base, drainage, blinding, etc.

Work closely with your supplier to schedule deliveries that reflect your build sequence. This helps reduce idle stock on site and makes it easier to keep quality control tight.

Choose a supplier who understands scale

For commercial sites, you need a supplier with proven capacity. At Armstrongs, we operate multiple quarries across the North West and a large modern fleet of tipper wagons, meaning we can supply bulk loads to multiple sites simultaneously, without holding you up.

Look for suppliers who offer:

  • Multiple vehicle types (e.g. 8-wheelers, artics)
  • Full traceability and BS EN certification
  • Flexible delivery slots
  • The option for timed or staged deliveries

Consistency is key here. A good supplier won’t just deliver, they’ll slot into your wider programme and help you stay on track.

Plan delivery slots with site logistics in mind

Your site layout and access points matter. If you’re on a tight urban site or a shared industrial estate, delivery timings need to work around other trades and traffic flow.

  • Can your site take 20–30 tonne loads?
  • Do you need to book unloading equipment?
  • Is there enough space for safe tipping?

Coordinating deliveries with your site manager or logistics lead ensures everything arrives safely and gets used promptly, without holding up other operations.

Think about storage and staging

On bigger sites, it’s rare that aggregates get used as fast as they arrive. If your delivery is split over phases, think about:

  • Where stockpiles will be kept
  • How to avoid contamination or runoff
  • What signage or segregation is needed

Clean, dry storage matters, especially for materials like sand, which can affect your mix if it’s too wet or muddy.

Coordinate deliveries with batching plant requirements

If you're pouring structural concrete on site or off-site via a batching plant, you’ll need a consistent flow of aggregate that matches your mix design. Sudden changes in material size or type can throw off your ratios or affect strength.

Flag early if your project requires multiple concrete grades or specific aggregate types. At Armstrongs, we can source and supply exactly what your plant or pour needs, with full traceability and certified quality.

Check environmental conditions and compliance

Sites near waterways, protected land, or urban zones often come with strict environmental controls. That includes dust suppression, sediment control, and restricted vehicle movements.

Planning your deliveries with those rules in mind avoids fines, delays, or rework. Ask your supplier if their vehicles are compliant and what steps they take to reduce dust or runoff during tipping.

Build in buffer for weather and demand spikes

Even with the best planning, things happen. Rain can delay groundworks, delivery vehicles can get stuck, and workloads can spike mid-project. It’s worth having:

  • Buffer stock on site (if space allows)
  • Clear comms with your supplier about flexible loads
  • A contingency plan if extra tonnes are needed quickly

Working with a supplier who can respond fast makes a real difference when deadlines are tight.

Get the paperwork sorted early

On larger commercial builds, delivery paperwork isn’t just a formality. You’ll often need:

  • Material test certificates (BS EN compliance)
  • Waste transfer notes (for recycled aggregates)
  • Chain of custody documents (for QA and audits)

Working with a supplier like Armstrongs means you’ll get everything logged, filed, and ready for inspection from day one, saving you hassle mid-project.

Armstrongs can support every stage

We supply aggregates for everything from sub-base to structural concrete - direct from our own quarries, in bulk, and on time.

We’ve helped deliver materials to some of the North West’s largest infrastructure, construction, and energy projects, and we’re set up to handle complex schedules, multi-phase delivery plans, and high-volume demand.

If you’ve got a job coming up and want to make sure the materials side runs smoothly, our team’s on hand to help plan it with you.

Aggregate Delivery Planning FAQs

How much notice do I need to give for an aggregate delivery?

We recommend giving at least 48–72 hours' notice for standard loads, especially during busy periods. For larger or more complex deliveries, more time may be needed. Always check with your supplier early in the planning stage.

Can I get aggregate delivered outside of normal working hours?

Yes, depending on the supplier and project location, early morning or weekend deliveries can often be arranged. At Armstrongs, we aim to be flexible around your site schedule, but advanced notice is essential.

How much aggregate can be delivered in one load?

Our 8-wheel tippers carry up to 20 tonnes per load, and articulated tippers can handle up to 29 tonnes. For bigger jobs, multiple loads can be scheduled back-to-back.

What types of aggregate can be delivered in bulk?

Most standard construction aggregates, including MOT Type 1, crusher run, granite, gritstone, and sand, can be delivered loose in bulk or bagged for more controlled use.

What happens if access to a site is restricted?

Let your supplier know in advance. We can assess access and advise on the right vehicle or delivery method. Narrow entrances, weight restrictions, or tight turnarounds don’t have to cause delays, but they do need planning for.

Can I arrange a mix of different aggregates in one delivery?

Where possible, yes. If your project needs a range of materials, we can help coordinate multiple deliveries to keep everything on site when it’s needed.
