Asphalt and concrete subcontracting

Asphalt & Concrete Subcontracting for General Contractors

For a general contractor, paving is one package inside a much larger sequence. The subcontractor must understand site readiness, elevations, utility and concrete interfaces, procurement, mobilization, and the opening date, not just the day asphalt reaches the paver.

The commercial decision

What should general contractors expect from a paving partner?

A useful paving subcontract scope defines what must be ready before mobilization, who owns grading and testing, how asphalt meets concrete and structures, when markings and stops follow, and which schedule changes affect remobilization or production.

Ground-up and reconstruction projects involve overlapping responsibilities. Earthwork, utilities, drainage, curb and gutter, walks, asphalt base, paving, markings, signage, landscaping, and owner turnover can all affect the paving package.

The strongest subcontract scope does not leave interfaces implicit. It states subgrade or aggregate readiness, survey and layout responsibility, elevations, tack and lifts, testing or inspection expectations, access for equipment, haul routes, traffic control, and the areas included.

MD Asphalt Company can coordinate asphalt and concrete scopes with the general contractor's look-ahead schedule. Bid invitations should include current plans, specifications, addenda, alternates, anticipated quantities, site logistics, procurement requirements, and the date the work area will actually be ready.

Decision snapshot

What belongs in the first project conversation?

Start with the operating facts and the condition of the site. The paving method should follow those facts, not lead them.

Scope intelligence

Which project priorities prevent an under-scoped bid?

The lowest number can describe a different project. A decision-ready scope makes condition, responsibility, access, sequence, and exclusions visible before award.
  1. 01

    Site-readiness definition

    Confirm who owns subgrade, aggregate, compaction, testing, survey, layout, fine grading, proof roll, drainage structures, and acceptance before the paving crew mobilizes.

  2. 02

    Trade interfaces

    Coordinate curb and gutter, sidewalks, building entries, loading docks, utility structures, landscaping edges, signs, and striping so elevations and sequence remain buildable.

  3. 03

    Current documents

    Price the latest plans, specifications, addenda, alternates, phasing notes, and quantities. A clean revision chain prevents an outdated surface plan from driving procurement.

  4. 04

    Look-ahead communication

    Share schedule changes early enough to protect production, crew, haul, and material coordination. A target date without confirmed readiness increases remobilization risk.

  5. 05

    Closeout sequence

    Plan final lift, punch repairs, striping, stops, signage interfaces, cleaning, owner walks, and turnover instead of treating paving as complete when the last truck leaves.

Condition before treatment

Which commercial pavement scope fits each kind of need?

Repair, preservation, resurfacing, and replacement solve different conditions. The useful choice is the one that matches support, drainage, traffic, and intended use.
ScopeBest fitDecision value
New construction paving Ground-up commercial, institutional, industrial, and site-development workCoordinates base readiness, asphalt lifts, elevations, drainage, concrete interfaces, and schedule milestones.
Milling and rehabilitation Renovation, redevelopment, tie-ins, and occupied-site improvementsControls surface removal and transitions before new asphalt is placed.
Concrete flatwork Curbs, gutters, walks, pads, slabs, and asphalt transitionsKeeps adjoining surface scope coordinated when one subcontract package is more efficient.
Patching and tie-ins Utility work, phased construction, repairs, and existing-pavement connectionsRestores localized areas and creates controlled interfaces with the surrounding surface.
Striping and wheel stops Final layouts, traffic markings, stencils, and parking controlsCompletes the traffic plan after surface and cure requirements are satisfied.

From site to handoff

How does the commercial planning process stay useful?

The process should produce a buildable scope and a workable operating plan. Every step closes a decision the field team and property team would otherwise face later.
  1. 01

    Review the bid package

    Confirm drawings, specifications, addenda, bid form, alternates, quantities, insurance, schedule, site logistics, and the exact limits of asphalt and concrete responsibility.

  2. 02

    Resolve constructability

    Identify grade, drainage, utility, curb, building-entry, equipment-access, haul-route, and phasing questions before they become field conflicts.

  3. 03

    Tie scope to readiness

    Define the conditions required for mobilization and the communication path for acceptance, schedule shifts, weather decisions, and changed quantities.

  4. 04

    Execute within the site plan

    Coordinate deliveries, equipment, work zones, other trades, inspections, and temporary access while maintaining the agreed production sequence.

  5. 05

    Finish for turnover

    Complete tie-ins, punch work, striping or stop coordination, cleanup, requested documentation, and the handoff to the general contractor and owner.

Proof before proposal

What should the decision record contain?

Commercial buyers should leave the planning stage with more than a total. The record should show what was observed, what is included, how the site operates, and which assumptions affect schedule or price.

MD Asphalt's first-party planning model reviews condition, drainage and adjoining surfaces, traffic and load, access, phasing, and the finish sequence. That six-part review creates a repeatable way to compare urgent repair, preservation, resurfacing, and replacement without forcing every site into the same recommendation.

This is a decision model, not a remote engineering conclusion. Final recommendations depend on the field condition, project documents, property use, and the information available during the site review.

  • Current-plan and addendum acknowledgement in the pricing conversation
  • Clear responsibility boundaries for grading, testing, layout, and surface work
  • Commercial paving, milling, concrete, repair, and striping capability
  • A direct project contact for look-ahead and field coordination
  • Licensed and insured documentation available for prequalification review

Buyer-specific answers

What should general contractors clarify before requesting a bid?

Share operating constraints and procurement requirements with the condition concerns. That information changes the scope, phase plan, and proposal assumptions.
01What should a general contractor include in a paving bid invitation?

Include current civil and architectural plans, specifications, addenda, bid form, alternates, quantities, phasing, site logistics, insurance requirements, work-hour limits, target dates, and the responsibilities assigned to earthwork, concrete, testing, survey, and striping.

02Can MD Asphalt coordinate asphalt and concrete scopes?

Yes. The bid should identify the exact concrete items and interfaces, including curbs, gutters, walks, pads, slabs, entries, and drainage transitions. Coordinated scope is most useful when elevations and sequence are shared.

03How should site readiness be confirmed?

The parties should agree on subgrade or aggregate condition, compaction and testing, grades, drainage structures, utility adjustments, curb completion, access for equipment, and who accepts the area before paving mobilization.

04Do you provide procurement and insurance documentation?

MD Asphalt Company is licensed and insured. Send project-specific prequalification forms, insurance limits, contract exhibits, and submission deadlines so the required documentation can be reviewed for the bid.
