Why AEn
Built for estimating decisions, not generic calculators.
Keep intrinsic activity characteristics in the Base MH and project conditions in separate adjustment factors.
Dynamic project factors
Adjust for access, congestion, height, repetition, logistics, testing and trade-specific site conditions.
Transparent MH/Unit
See original Base MH, effective base, total adjustment and final adjusted MH/Unit instead of a single black-box rate.
Production/day
Translate man-hours into practical crew output using controlled crew size and working hours.
Labor cost
Connect productivity directly to labor cost using discipline-controlled Civil and MEP labor rates.
Confidence model
Separate strong benchmark activities from modeled or specialist items that still require project calibration.
How it works
From activity selection to an auditable productivity result.
01
Search
Select the exact construction activity and intrinsic variant.
02
Set conditions
Choose the applicable project and trade factors.
03
Calculate
AEn applies sensitivity and profile caps to the controlled base.
04
Use the result
Review adjusted MH/Unit, production/day, labor cost and confidence.
Database Coverage
One engine across major construction work groups.
The database continues to expand through controlled revisions and source-led gap analysis.
Structures
Concrete, reinforcement, formwork, precast, repair, strengthening, steel and timber.
Architectural & Finishes
Masonry, roofing, waterproofing, doors, glazing, stone, marble, granite, wood, ceilings, floors and coatings.
MEP
Fire protection, plumbing, HVAC, BMS, electrical, ICT/AV, fire alarm and security.
Civil & Infrastructure
Earthworks, shoring, dewatering, paving, irrigation, utilities, roads, rail and marine.
Specialist Systems
Healthcare, secure communications, special doors, cleanrooms, conveying and specialty equipment.
Industrial / Process
Process piping, material handling, treatment systems, industrial equipment and renewable power.
For construction teams
Useful from tender stage through calibration.
EstimatorsBuild labor rates and benchmark productivity quickly.
Cost EngineersTrace productivity assumptions behind unit-rate build-ups.
Tendering TeamsCompare project conditions without changing the controlled base.
ContractorsUse actual performance later to calibrate future benchmarks.
FAQ
Questions before you start.
What does MH/Unit mean?
Man-hours required to complete one measured unit of an activity. AEn separates the controlled Base MH/Unit from project-condition adjustments.
Does AEn replace an estimator's judgement?
No. It structures the productivity logic, exposes assumptions and confidence, and gives the estimator a consistent starting point for review.
How does the free trial work?
You can calculate 10 unique activities free. Recalculating the same activity does not consume another unique-activity allowance.
Are Civil and MEP treated the same?
No. The engine supports discipline-specific labor rates and trade-specific MEP factor profiles rather than applying one generic civil factor set to every trade.
Can the database keep growing?
Yes. AEn is revision-controlled and is designed to add new activities, variants and specialist systems while retaining parent-benchmark and confidence information.
