Architecture & Engineering Services Ltd
Three ways to work with AES: buy a finished engineering tool outright, commission a bespoke one, or appoint us for insured civil and structural engineering under an NEC4 Professional Services Contract.
Finished spreadsheets and calculators, built on real project work and sold as-is. Free tools download immediately with no account needed.
Installer for the AES Markdown Viewer — a lightweight desktop application for viewing and navigating Markdown documents, styled to match this site. Version 1.0.0, Windows 64-bit. The installer is unsigned, so Windows SmartScreen may ask you to confirm: choose More info, then Run anyway.
Axial geotechnical pile capacity tool — shaft and base resistance with code-based checks, sized from 50m marine piling work.
Full fee-estimating workbook — builds scope, resource hours and rates into a transparent, defensible commercial fee.
Both code blocks for Part 03 as plain text: the Worksheet_Change event for the Inputs sheet and the modRevenue standard module. Paste them into the macro-free workbook to build the auto-resizing cash-flow table yourself.
The same Part 03 model as a plain workbook, for paste-your-own-code along with the supplied module and worksheet event.
The finished build with the VB macro that auto-expands and contracts the cash-flow table to match the design life. Macro-enabled.
Adds the external currency list through Power Query and the conditional-formatting engine that swaps the currency symbol across the model. No macro required.
The Inputs and Revenue sheets. Annual output, price, design life, discount rate, O&M and CAPEX, driving a fifteen-year payback table.
Nothing to install and nothing to keep updated. Some are free once you have an account; others need a licence for commercial use, priced on the same basis as the spreadsheets.
Indicative professional fees from the AES fee model — construction value or floor area, six value bands to £150M, discipline split, the three role rates and the stage payment schedule.
Assembles an NEC4 Professional Services Contract appointment — Main Option, BIM tier, calculation packages, PI level, liability cap with a live cap-versus-cover check, X-clauses and the payment schedule.
Drop a .md file and read it rendered in the house style — headings, tables, code and contents. Nothing is uploaded; the file never leaves your machine.
Permanent salary vs Inside-IR35 day-rate, compared like for like — pension, holiday, employer costs and take-home, side by side.
A spreadsheet, calculator or web application built for your specific problem — your codes, your parameters, your workflow. Scope is agreed and priced in writing before any work starts; the fee comes from the same model behind the public Fee Estimator.
REVIT models, drawings and MasterSeries calculations to the British Standards and Eurocodes, delivered under a signed NEC4 Professional Services Contract with professional indemnity cover. Use the NEC4 Builder to see how an appointment is assembled before you enquire.
