Car Parks & Internal Access Roads
NLS Contractors builds car parks and internal access roads for hospitals, warehouses, compounds and commercial sites in Riyadh, Jeddah, Dammam, Khobar and across the Kingdom: paving, drainage falls, kerbs, markings and signage. Handover includes a levels survey, test records and as-builts.
Internal roads are where a site works day to day: ambulance routes, truck circulation, staff parking and visitor bays. The package covers paving, drainage falls, kerbs, markings and signage as one scope, so the surface, the water and the paint are coordinated and not left to meet at the end.
The build-up is a compacted subgrade, an aggregate base, then asphalt or interlocking pavers, depending on traffic and finish. Asphalt suits truck routes and larger car parks. Interlocking pavers suit forecourts, entrances and areas over services that may need reopening. Layer testing follows the same methods as roads: modified Proctor, CBR and field density on the base before the surface goes on.
A car park is a surface that has to shed water. Falls toward gullies, channels or a storm connection are set out from the drainage drawings before the base is laid, because flat spots hold water and fail early. Hospital forecourts and warehouse yards also take wash-down water, and short heavy storms in Jeddah and Riyadh test the gullies. Finished levels are surveyed and the survey goes into the handover.
The pavement meets lighting pole bases, utility crossings and manholes, shade structure footings and barrier gates, and these are set out together. Sleeves under the road for future cables are placed before paving, because cutting new asphalt is a repair nobody wants. Markings cover bays, arrows, accessible bays and pedestrian crossings, and signs and wheel stops follow the layout.
Heavy vehicles change the specification. A warehouse yard with truck and container traffic needs a pavement designed for it, so the pavement design in the drawings governs, and the offer prices that build-up. Works on a live hospital or warehouse site are phased by zone, with the ambulance or truck route kept open. Send the site plan, the levels and drainage drawings, the pavement details, the marking layout, the BOQ, the site city and the access hours.

Frequently Asked Questions
Asphalt or pavers for a car park?+
Asphalt suits truck routes and large car parks and lays faster over wide areas. Interlocking pavers suit forecourts, entrances and zones over services that may need reopening. The pavement design names the choice.
How do you stop water ponding in a car park?+
By setting falls to gullies or channels from the drainage drawings before the base is built, then surveying the finished levels. Ponding is almost always a levels problem and not a surface problem.
Can the car park be built while the facility is open?+
Yes, phased by zone with the ambulance or truck routes kept open. State the access constraints and working hours in the enquiry.
Are shade structures and lighting poles part of this package?+
The pavement is coordinated with their footings and sleeves. Shade structures and poles are separate packages unless the BOQ includes them.
