    Preconstruction and cost consulting for the landscape industry

    Six core capabilities, each with a clear sense of what it is, who it's for, and what you walk away with — plus advisory support for the in-between work.

    01 / 06

    Preconstruction Consulting

    ASC brings senior preconstruction judgment to the earliest stages of a project, when decisions are least expensive to change. From concept and feasibility through bid readiness, we help teams frame scope, sequence, and cost expectations so that design intent and budget stay aligned as the project develops.

    Who it's for

    Developers, owners, and landscape contractors who want experienced cost perspective before committing to a design direction or contract structure.

    What you walk away with

    A clear preconstruction cost framework, scoped assumptions, and decision-ready guidance you can act on with confidence.

    02 / 06

    Conceptual Estimating & Budgeting

    During design development, ASC advises on cost and provides conceptual estimates and quantity takeoffs that translate drawings and intent into defensible numbers. As the design evolves, budgets are tracked against scope so cost drift is caught early — not after bid day. This is senior cost guidance, not a production-estimating hand-off.

    Who it's for

    Landscape architects, designers, and owners who need budgets that hold up as concepts mature into construction documents.

    What you walk away with

    Conceptual estimates, quantity takeoffs, and a living budget that moves with your design.

    03 / 06

    Estimate & Bid Reviews

    ASC provides an independent second set of eyes on estimates, bids, and quantity takeoffs — checking for gaps, omissions, unit-cost realism, and scope coverage before a number is submitted or awarded. The goal is to surface exposure while there is still time to act on it. This is review and validation, not producing estimates on your behalf.

    Who it's for

    Landscape contractors validating their own numbers before bid day, and owners/developers reviewing bids before award.

    What you walk away with

    A documented review flagging gaps, risk areas, and recommendations to strengthen or validate the number.

    04 / 06

    Value Engineering & Constructability Review

    ASC reviews plans and specifications for constructability and cost efficiency — identifying value-engineering alternatives and flagging buildability issues that would otherwise surface as change orders. The focus is practical: what can be built more efficiently without compromising design intent.

    Who it's for

    Designers and owners who want to protect the budget and the schedule without sacrificing the design.

    What you walk away with

    A prioritized list of VE alternatives and constructability flags, with cost and risk context for each.

    05 / 06

    Bid Strategy & Risk Analysis

    ASC helps project teams think clearly about cost, procurement approach, and risk exposure before commitments are locked in — where the competitive edge is, where the risk is, and how to price for both. We translate project documents into a strategy that is competitive without being reckless.

    Who it's for

    Landscape contractors and owners who want a sharper read on a project before committing their number or awarding the work.

    What you walk away with

    A bid strategy and risk assessment that clarifies where to compete, where to protect margin, and where the exposure sits.

    06 / 06

    Estimator Training & Mentoring

    ASC helps firms build estimating capability from within — mentoring junior estimators, establishing repeatable processes, and transferring the judgment that comes from two decades inside landscape construction. This is advisory development work, not outsourced estimating capacity. The goal is leaving your team stronger than we found it.

    Who it's for

    Landscape contractors and design firms that want to grow durable in-house estimating capacity.

    What you walk away with

    Mentored estimators, documented processes, and a stronger estimating bench.

    Supporting Capabilities

    The in-between work

    Beyond the core services, ASC takes on the project-specific estimating and review work that firms often need a senior hand for.

    • Proposal and bid closeout review
    • Advisory estimating support during peak bid seasons
    • Owner and developer budgeting support

    Project-specific estimating support may be provided when appropriate.

    What ASC does not do

    Being clear about boundaries builds trust. ASC is a consulting firm — not a contractor, designer, or outsourced estimating department.

    • Landscape construction, installation, or maintenance
    • Landscape architecture or design services
    • Engineering services
    • Functioning as a full-time outsourced estimating department
