Quantivey — Construction Cost Consulting

Cost Certainty from Concept to Closeout

Quantivey partners with owners and businesses to deliver clarity, control, and confidence at every stage of construction — from earliest budgets to final closeout.

What We Do

Construction Cost Management, End to End

Quantivey is a construction cost management firm. We give owners and businesses independent control over what their projects cost — through rigorous estimating and budgeting before contracts are signed, disciplined oversight through construction, and specialist advisory where cost meets risk and capital decisions.

Pre-Contract

Cost Certainty Before You Build

Get the budget right before commitments are made, while design decisions can still be changed affordably.

  • Conceptual & Schematic Cost Estimates

    Early-stage estimates built from limited design information — concept sketches, schematic drawings, or a program narrative — to establish a realistic budget before significant design investment. Used by owners to test feasibility and secure funding before committing to full design.

  • Design Development & Construction Document Estimates

    Progressively detailed estimates produced as drawings mature through the DD and CD phases, keeping the project aligned to budget and catching cost drift while it’s still inexpensive to correct.

  • Value Engineering & Cost Optimization

    Systematic review of design, systems, and materials to reduce cost without sacrificing function, quality, or schedule — presenting owners with priced alternatives and trade-offs rather than blunt cuts.

  • Constructability & Bid Document Review

    Independent review of drawings and specifications before they go out to bid, identifying gaps, conflicts, and ambiguities that otherwise turn into RFIs, change orders, and inflated bids.

  • Budget Reconciliation & Trend Analysis

    Reconciling estimates across design stages and bidder pricing to explain variances, track cost trends over the life of the project, and give owners a defensible, current budget picture.

  • Procurement & Bid Strategy Support

    Advising on bid packaging, delivery method, and procurement strategy, then analyzing bids on a like-for-like basis so owners can compare contractors fairly and award with confidence.

Post-Contract

Cost Control While You Build

Protect the budget through construction, and pay only for what’s contracted and delivered.

  • Change Order Review & Negotiation

    Independent evaluation of contractor change-order pricing for fairness and contract compliance, with negotiation support that protects owners from inflated or unjustified costs during construction.

  • Pay Application & Schedule of Values Review

    Reviewing the schedule of values and monthly pay applications to confirm billed amounts match actual progress — protecting owners from front-loading and overpayment.

  • Cost-to-Complete & Forecasting

    Ongoing forecasting of final cost based on committed costs, pending changes, and remaining work — giving owners early warning of overruns while there’s still time to act.

  • Project Closeout & Final Cost Audits

    Verification of final costs, reconciliation of allowances and contingencies, and audit of final billings at closeout to confirm the owner paid only for what was contracted and delivered.

Specialist & Advisory

Where Cost Meets Risk & Capital Decisions

Specialist support where cost meets risk and capital decisions.

  • Risk & Contingency Management

    Identification, quantification, and active management of cost risk across the project lifecycle. We pressure-test the estimate, build and justify appropriate contingency, run quantitative risk analysis on the budget, and track how that contingency draws down as the project progresses — so owners understand not just the number, but the confidence behind it.

  • Project Due Diligence & Cost Validation

    Independent cost review for owners, investors, and lenders before they commit to acquiring, funding, or restarting a project. We validate budgets and third-party estimates, assess the realistic cost to complete or remediate, and flag financial exposure — so a capital decision rests on a defensible number rather than the seller’s or contractor’s word.

Common Questions

Frequently Asked Questions

From where our name comes from, to the history of our profession, to when to bring us into a project — the questions we get most often.

What does “Quantivey” mean?

“Quantivey” derives its name from the profession of Quantity Surveying. We took the centuries-old craft of quantity surveying and built a modern construction cost consulting practice around it.

What is a Quantity Surveyor?

A quantity surveyor (QS) is a construction cost specialist who measures, estimates, and manages the financial side of a building project. From earliest concepts through final closeout, a QS prepares cost estimates from design drawings, value-engineers designs to fit budgets, reviews payments and change orders during construction, and audits final costs at completion. The role is fundamentally independent — representing the owner’s financial interests rather than the contractor’s.

Where did quantity surveying come from?

The profession traces its roots to 17th-century Britain. After the Great Fire of London in 1666, the scale of rebuilding pushed the building trades away from paying craftsmen by the day toward measuring and paying for completed work — a shift widely credited as the birth of the discipline. The first known firm, Henry Cooper & Sons of Reading, was established in 1785, and the term “quantity surveyor” itself entered common use in the mid-1800s.

The profession was institutionally formalized in 1868, when 49 surveyors met at London’s Westminster Palace Hotel to found the Institution of Surveyors — granted a Royal Charter in 1881 and renamed the Royal Institution of Chartered Surveyors (RICS) in 1947. Through the British Commonwealth the profession spread to Australia (where the Australian Institute of Quantity Surveyors was founded in 1971), New Zealand, South Africa, Hong Kong, and beyond — where today it’s a regulated profession with chartered designations such as MRICS and FRICS. In the United States the same skill set is practiced under titles like construction estimator, cost consultant, and cost engineer.

How is a quantity surveyor different from a general estimator?

Three things. Breadth — a QS works across the full project lifecycle, from earliest budgets through closeout audits, not just one phase. Independence — a QS traditionally represents the owner or developer, advising on cost without conflict of interest with the contractor. Discipline — the practice is rooted in measurement and rigorous documentation, providing transparent cost certainty rather than ballpark numbers.

When should I engage Quantivey on a project?

At or before conceptual design. The biggest savings come from rigorous budgeting and value engineering early — long before contracts are signed. That said, we add value at every stage: we can step in mid-construction to manage change orders and pay applications, or at closeout to audit final costs and resolve disputes.

What sectors do you work in?

Healthcare, hospitality, K–12 and higher education, tenant improvements, retail, industrial, data centers, multi-family and residential, and commercial office.
