Frequently Asked Questions

Practical answers before you send a request.

Find the right service, understand how fees are shaped, and see what information helps Horizon review your project.

Services and deliverables

What types of contractors do you support?

Horizon supports underground-utility, civil site-development, sitework, grading and earthwork contractors within confirmed capability, general contractors needing civil-scope support, and estimating teams needing additional capacity.

Which civil scopes do you review?

Supported civil scopes include storm, sanitary sewer, water, fire-service utilities, erosion control, clearing, earthwork review, aggregate base, paving, curb, sidewalk, and related civil work. Final scope is confirmed by project.

Do you provide quantities only or priced estimates?

Pricing responsibility is defined in writing. A Civil Quantity Package is not automatically a fully priced estimate, and the contractor always retains responsibility for final pricing and bid submission.

What estimate-detail options are available?

Options include Quantity Takeoff Only, Customer-Priced Cost Estimate using labor and material costs supplied by the customer, and Vendor-Informed Cost Estimate using current pricing supplied by the customer. The selection is separate from the requested service.

What deliverable formats are available?

Depending on the accepted scope, representative deliverables may include quantity summaries, scope breakdowns, bid-support worksheets, estimate summaries, marked plan excerpts, plan-reference notes, assumption and clarification logs, and organized PDF or spreadsheet files. The written proposal identifies the actual deliverables for the project.

Fees, labor, and changes

How are fees and payments handled?

The standard consulting rate is $100 per hour, with a $600 minimum engagement fee. The proposal states the final project price. The engagement fee is a down payment credited toward that price, not an additional charge. It is refundable if the project is canceled before work begins and nonrefundable once work has begun. The remaining balance is due before the final deliverable is released.

What is included in a vendor-informed estimate?

Horizon may review and incorporate current vendor, subcontractor, material, or equipment pricing supplied by the customer. Additional effort may be required to reconcile quote coverage, units, alternates, freight, taxes, exclusions, validity dates, and missing pricing. The customer remains responsible for verifying quote completeness and final bid use.

How are labor and material costs handled?

For priced estimates, the customer supplies the labor and material costs to be used. Horizon does not procure material pricing or assume the contractor's labor rates, productivity, burdens, or material costs. The written proposal identifies the supplied pricing basis, and the contractor remains responsible for final pricing.

How is delivery timing determined?

Delivery timing is confirmed after the plans, scope, complexity, required deliverables, and bid deadline are reviewed. No universal turnaround is promised.

How are addenda and revised plans handled?

Addenda and revised plans are not included in the original scope price unless the proposal expressly says otherwise. Additional pricing depends in part on the percentage of the original work already completed when the change is received, as defined in the agreement.

What review or revisions are included?

When Horizon prepares the estimate, one review is included. Estimate revisions, expanded review, or a second review are additional work. Review of an estimate not prepared by Horizon is separately scoped and priced. New addenda, changed plans, expanded responsibilities, or requested rework outside the accepted scope are also additional work.

Topcon-compatible models

Do you prepare Topcon-compatible machine-control models?

Yes. Horizon can prepare office-based proposed-grade models in Topcon 3D Office and deliver a Topcon-compatible .tp3 file for most earthmoving or pipelaying equipment fitted with Topcon GPS controls. Available plan features may include pads, streets, curb and gutter, utility trenches, and ponds. This reflects practical Topcon experience, not formal Topcon certification or affiliation.

What source files and control information are needed for a model?

PDF plans are the minimum source for estimating. CAD files are requested for machine-control model work so the site can be positioned to the identified state-plane coordinate system and reduce unnecessary transcription risk. Horizon can enter customer-provided control points, but the contractor or surveyor must verify control and perform onsite localization and calibration.

Who is responsible for using the model in the field?

The contractor or surveyor remains responsible for control verification, onsite calibration, machine setup, tolerances, field checks, final grades, and construction means and methods. Horizon’s service is office-only and does not replace the controlling plans, engineering design, or survey services. Revised plans or requested model changes may require an additional fee.

Documents and responsibilities

Are project documents confidential?

Project information is used to review the request and perform accepted work. Customer documents are not published without specific written authorization. See the Privacy Notice for information handling and the current review status.

Will Horizon display customer projects or plans?

Not without specific written publication authorization. Horizon will not display or reference customer projects, plans, deliverables, project results, or identifying details in website, portfolio, social-media, proposal, or case-study materials without that permission. Public examples use fully synthetic, fictional content.

What does the contractor remain responsible for?

The contractor always retains responsibility for final pricing, labor multipliers, production decisions, means and methods, site conditions, bid compliance, risk decisions, proposal use, and bid submission. Acceptance of a deliverable does not convert Horizon's estimate into a guaranteed cost or transfer the contractor's final-pricing responsibility.

What if a quantity appears incorrect?

Contact Horizon with the document reference and the quantity you would like reviewed. Horizon reviews the issue against the accepted scope and controlling documents. The engagement defines correction and clarification procedures; a new plan or expanded scope may require additional work.

Does Horizon guarantee accuracy or bid results?

No. Horizon does not guarantee bid results or final project cost. Estimating support is not engineering certification or a substitute for the contractor’s final review.

How long is job information kept?

For an accepted proposal, job information is retained for 30 days after the paid estimate is delivered, then deleted unless different arrangements are agreed to in writing. If no proposal is accepted, job information is deleted within 7 days after the proposal or project request is refused or declined.
