AWTT modular floating cover installed across an industrial pond — used to illustrate the specification builder

Engineering Calculator

Floating Cover Specification Builder

Turn pond dimensions, design wind speed, and application into a copy-ready CSI 3-part specification section — with product selection, piece count, and an indicative budget band.

Use the Calculator Request a Quote

Most floating cover projects are lost or won at the specification stage, long before a quote is requested. The AWTT Specification Builder generates a complete CSI-format 3-part section (Part 1 General, Part 2 Products, Part 3 Execution) from four inputs: surface area, design wind speed, application, and whether heat retention is required. It selects a product from the published AWTT range, computes piece count from real coverage density, and attaches an indicative budget band drawn from the published price tranches.

Every figure the builder emits traces to published AWTT technical data and the public price tranches — nothing is modelled or invented. Output is free and ungated: copy it to the clipboard, download it as a text file, or hand it straight to AWTT as a pre-filled quote request. Specifiers may use the generated text in project documents without attribution.

Application

Primary objective

Heat retention is a project requirement. Restricts selection to insulated products (R-4 and above). Note that the highest R-value product carries the lowest wind rating.

The Problem — Why It Matters

Facility operators and engineers face these measurable challenges that AWTT floating covers directly address.

Spec Sections Get Written From Competitor Datasheets

When no neutral specification text exists, engineers copy language from whichever supplier datasheet is nearest to hand. That bakes one vendor's geometry and tolerances into the project documents, and every other bid then arrives as a substitution request.

Design Wind Speed Is Specified Last, Not First

Wind is the single constraint that eliminates most of the product range, yet it is usually added to a spec after the cover type has been chosen. A 40 MPH-rated insulated cover written into a 110 MPH design-wind site is a failure scheduled for the first storm season.

Piece Count and Area Get Confused on the Quote Line

AWTT sells by the square foot, not by the piece — 2.62 tiles or 10 balls make one square foot. Specs written in piece counts arrive at procurement as quantities that are off by an order of magnitude, and the error is usually caught only at order confirmation.

Potable Contact Requirements Are Applied Too Broadly

Drinking-water projects need NSF/ANSI 61 certified contact material, and only one product in the AWTT range is offered in that resin. Specs that apply the requirement to every product — or omit it entirely — either eliminate valid bidders or admit non-compliant ones.

No Budget Number Until a Quote Is Requested

Engineers writing a feasibility study or a capital request need an order-of-magnitude cost before they can justify a formal RFQ. Suppliers who withhold all pricing until contact push that work back onto the specifier, who then guesses.

Every Revision Restarts the Whole Document

Change the design wind speed or add a heat-retention requirement and the product, the piece count, the R-value clause, and the budget all move together. Hand-edited spec documents drift out of internal agreement with each revision.

The AWTT Solution

Modular, maintenance-free floating covers engineered to directly solve specification builder challenges in industrial liquid containment.

CSI 3-Part Format, Ready to Paste

Output follows the standard Part 1 General / Part 2 Products / Part 3 Execution structure specifiers already use, with submittals, quality assurance, delivery and storage, and installation articles populated from AWTT published data.

Wind Filter Applied First

Design wind speed is the first filter, not the last. Products rated below the site design wind are eliminated before any other criterion is considered, so the recommendation is always structurally valid for the site.

Piece Count From Real Coverage Density

Quantities are computed from published coverage density — 10 spheres per sq ft, 2.61–2.62 tiles per sq ft — and reported in both square feet and pieces, with the square-foot figure flagged as the quote line item.

Potable Logic Reflects the Actual Certification

Selecting a potable application restricts the recommendation to Hexprotect AQUA, the only AWTT product offered in NSF/ANSI 61 certified, FDA-compliant resin — and the generated text states plainly that the certification is held by the resin, not the finished assembly.

Indicative Budget Band Included

The published price tranche for the selected product is applied to your area to produce a budget range, with the resin index and freight called out as separate lines rather than buried in a single number.

Frequently Asked Questions — Specification Builder

Common questions from engineers and operators using this calculator.

Is the generated specification free to use in my project documents?

Yes. The output is free and ungated, and specifiers may paste it into project documents without attribution or licence. It is written as neutral performance language rather than as sales copy, so it can be issued for competitive tender.

Where do the numbers in the specification come from?

Coverage, wind rating, R-value, buoyancy, evaporation reduction, warranty, and design life are taken from AWTT published product data. Budget bands come from the published price tranches. The builder does not model or estimate any figure that AWTT has not published.

Why does selecting a potable application restrict the product list?

Hexprotect AQUA is the only AWTT product offered in NSF/ANSI 61 certified, FDA-compliant HDPE resin (21 CFR 177.1520). The certification is held by the resin, not the finished cover assembly, and the generated specification states that distinction explicitly so it survives review.

How accurate is the budget band?

It is indicative, not a quote. The band is a straight line between the published small-quantity and large-quantity prices for the relevant tranche; the discount curve between those endpoints is not published and is not interpolated. The resin index and freight are shown as separate lines because both move independently of product price.

Should quantities be specified in pieces or square feet?

Square feet. AWTT sells by the square foot — 2.62 tiles or 10 spheres make one square foot — so a quantity line expressed in pieces will be misread by roughly an order of magnitude. The builder reports both, and marks the square-foot figure as the quote line item.

What if my design wind speed exceeds every product rating?

The builder tells you so rather than recommending a product that would fail. Above 130 MPH the correct response is a site-specific engineering review with AWTT, since ballast configuration and perimeter treatment become project-specific.
