AI Construction Project Management in Spain

Schedule, budget, risks, documents, photo progress and client reporting — one weekly and monthly loop on top of your tools. AI prepares summaries, checks and drafts; decisions and signatures stay with you and your dirección facultativa.

from 10 days pilot on a live project · a full monthly cycle in 4–5 weeks

−4 h/wk of the manager's time on summaries and checks · [estimate] — measured at diagnosis

≈2–2.5% of the project budget — the loop's cost · a human PM — 3–5% [market estimate]

1/3/10 years of LOE warranties — project file ready · LOE art. 17 · decision trail

Without a single loop, a project loses money in four places

01 · Problem

McKinsey, 09.08.2024 [ind.]

~10%

construction productivity growth over 2000–2022

Versus ~50% for the wider economy: project control is still manual — the schedule in Excel, actual costs in someone's head, site issues on WhatsApp.

Deloitte Access Economics for Autodesk, 2023 (preconstruction)

13.4 h/wk

spent finding and processing data

Summaries, photo sorting, invoice-vs-estimate checks, the client report — the manager works the information instead of the site.

[estimate] — measured on your project

2–3%

of margin leaks unlogged [estimate]

A chapter-level deviation surfaces at month-end certification, or at project end — when it is too late to fix.

And when the client asks «why is it like this?» — there is no decision trail: who approved, when, on what basis. A dispute file takes weeks to reconstruct.

We close project management — end to end

02 · The process we close

estimate → cost baseline scope of works → schedule weekly cycle: photos → summary monthly cycle: invoices → certification client report → decisions

CLASS

Class B · management (umbrella). The output is decisions, reports and plans; the lever — decision quality and speed, lower risk. Modules of other classes run inside the loop: estimates and invoices (C — document flow), photos and code checks (B — errors and disputes), the bot and proposals (A — revenue at the funnel entry).

Today — by hand

The weekly summary, invoice-vs-estimate check, client report draft and decision trail are compiled by hand — on weekends. Budget and schedule deviations surface after the fact.

With the system

Summaries, checks, certification data and the report are prepared by the AI loop; you confirm statuses and decide — that fits in a site meeting. Slippage and overruns visible weeks ahead.

Input → AI loop → output. And where the human is

03 · How it works

The loop sits on top of what you already use — Presto/CYPE/Excel, WhatsApp/Telegram, email. We replace nothing: we take your existing data flows and turn them into a managed cycle.

Input

What you already have

The project estimate — BC3 or Excel: becomes the chapter-level cost baseline
The scope of works and contract dates — become the schedule
The foreman's photos in a messenger — the way he already shoots them
Supplier invoices in the inbox, messages and site meetings

What the loop does

Builds the schedule: phases, milestones, dependencies, critical path — and updates it with actual progress
Sorts photos by phase and checks task statuses against the critical path
Turns invoices into actual costs and computes chapter-level deviations — amounts are cross-checked by code
Prepares the weekly summary, the relación valorada data and the client report draft

Output

What you get

Monday: a «done / in progress / at risk» summary with specifics — which task delays which milestones
For certification: budget control, relación valorada data, a PDF report in the client's language
Three jargon-free numbers: performed €X · spent €Y · plan says €Z (that's EVM — the EIA-748/ISO 21508 standard)
A risk & decision log — a dated project trail for the warranty period

Human

What the human does

The foreman confirms doubtful task statuses
You approve summaries and reports before sending — «on approval» level
Certifications are signed by the director de ejecución (LOE art. 13)
Decisions on risks, changes and prices are yours

RULE 01

Amounts and measurements are cross-checked by code, not by the model «by eye»: AI numeric errors in tables are documented, so the arithmetic belongs to the script.

RULE 02

Schedule and deviation forecasts support a decision, they don't guarantee a deadline: contract milestones and actions are your call.

RULE 03

Task statuses are confirmed by the foreman; anything doubtful is flagged «review», no silent substitutions.

RULE 04

Nothing reaches the client without a person's approval.

The loop across project stages

#15

The same loop runs the project from start to handover. Each stage has its tools and its boundary: what AI prepares and what stays with the person.

Pre-contract

Loop tools: Lead bot · estimate generator · proposal generator — a won contract enters the loop with its estimate ready

Where the human is: Price and offer — the owner's decision

Project start — first week

Loop tools: Estimate → chapter-level baseline · schedule: phases, milestones, critical path · channels and alert thresholds connected

Where the human is: Validating the works sequence and contract milestones

Weekly cycle

Loop tools: Photos by phase · statuses → «done / in progress / at risk» summary · critical-path alerts

Where the human is: The foreman confirms statuses; decisions at the site meeting

Monthly cycle

Loop tools: Invoices → actual costs · chapter-level deviations · relación valorada data · client report PDF

Where the human is: Disputed progress percentages; the DEO signs the certification (LOE art. 13)

Permanent layer

Loop tools: Risk & decision log (date, author, rationale) · CTE/LOE checks · meeting minutes

Where the human is: Risk decisions; on codes, the técnico has the final word

Handover

Loop tools: Punch list from accumulated issues · project file: timeline, documents, photos by phase

Where the human is: Acceptance — dirección facultativa; claims are run by a lawyer

The loop's modules — catalog services

The loop is assembled from litcore services already in production: each closes its own segment and plugs into the shared cycle.

Project schedule: phases, milestones, dependencies, critical path; updated with actual progress
Budget control: baseline from your estimate, actuals from invoices, chapter-level deviations, certification data
Weekly «done / in progress / at risk» summary + threshold alerts
Monthly client report (PDF, in the client's language: ES/RU/EN)
Risk & decision log — a dated trail with rationales

Five phases — a pilot on a live project from 10 days

05 · Implementation

Diagnosis

3–7 days · We dissect one live project: estimate, schedule, channels, certification cycle. We measure the baseline: hours on summaries and the lag before deviations surface.

Prioritization

1–3 days · The starting loop for your pain — usually schedule + summary + budget control. We fix the metric and the alert thresholds.

Pilot

from 10 days · The loop on one project: baseline, schedule, the foreman's channels, the first weekly cycle. A full monthly cycle shows in 4–5 weeks.

Measure & adopt

overlapping · Measurement on 4 axes: usage, time, errors, convenience. Guide + recorded walkthrough — your team works without us.

Scale

retainer · The loop rolls out to your other projects; modules join (photos, invoices, codes); thresholds tuned to your practice.

SLA: Summary — every Monday by 10:00 · certification pack — 2 business days before the date · alert — same day · answers ≤ 1 business day · If the pilot doesn't fit the window, the scope is too wide: we cut the scope, not the quality.

The economics, calculated conservatively

06 · Economic effect

ROI canvas for a typical project: a €250,000 renovation/build, 8 months, team — owner + site manager. Every assumption is flagged and recalculated with your data at diagnosis; no vendor numbers here.

Parameter	Value	Source / assumption
Process & class	managing the project — class B (umbrella)	litcore framework, block 2
Baseline: time on summaries, photos, checks, report	~6–8 h/week	[estimate] — measured at diagnosis
Baseline: lag before deviations surface	~4 weeks (certification cycle)	[estimate]
Lever 1 · manager's time	−4 h/wk × 4.3 wk × €43/h ≈ €740/mo	rate from the €380/day reference (Malt, 2026) [estimate]
Lever 4 · errors and rework	early detection ≈ 0.4% of budget ≈ €125/mo	[conservative estimate] — the pilot's deviation log
Lever 2 · procurement margin	invoice-vs-estimate checks ≈ €75/mo	[estimate] — the discrepancy log
Benefit/mo (conservative)	≈ €940/mo at steady state	adoption curve 40/70/100% over 3 months [estimate]
Costs	Start from €2,400 + €490/mo	«from» price — the owner approves

PAYBACK

≈ 8 months. Conservative, Start tier on one €250k project, with the adoption curve (base case — ~5 months). On 2–3 projects (Pro) the benefit is ×2.5 → payback ≈ 4 months. Separately, not in euros: the decision log is an asset for disputes and for the 1/3/10-year warranties (LOE art. 17).

Adoption: the weekly and monthly cycles run without remindersEfficiency: the manager's hours on summaries and checks — before/afterQuality: lag before deviations surface: weeks → daysConvenience: the team works from the guide, without us

Not financial advice: the calculation is a proposal built on market references; final numbers are fixed after the diagnosis and the pilot on your data.

Price — from €2,400 + €490/mo

07 · Price

Model: setup (one-off loop installation) + retainer per active project. Market anchors: unaccompanied software costs tens of euros a month, but nobody runs the project; a human project manager — 3–5% of budget [market estimate] or from €4,000/mo in the premium segment; AI monitoring — enterprise contracts from ~$10,000 for large projects. The litcore loop on a €250k, 8-month project ≈ 2–2.5% of budget — and it doesn't replace your manager: it reinforces them.

Risks and control

08 · Risks & control

Data

Only what the process needs enters the loop: estimate, schedule, photos, invoices. We sign a DPA before receiving real data; EU/US transfers are disclosed (EU-US DPF + SCC); some functions are not covered by Zero-Data-Retention — we flag it and configure safely.

Human control

«On approval» level: summaries, reports and certification data are AI-prepared — a person approves before sending. Amounts are cross-checked by code. Autonomy increases only after quality is confirmed.

AI Act, art. 50

From 02.08.2026 AI use is disclosed; reports and summaries carry the note of AI preparation with human review. Spain's AI bill (May 2026) enshrines human supervision — the loop is built on it.

Professional boundary

This service does not make litcore a building agent under the LOE: certifications are signed by the DEO, the site order book and acceptance belong to the dirección facultativa, safety to the coordinator (RD 1627/1997). The 1/3/10-year warranty liability (LOE art. 17) stays with the building agents: we give them better data, earlier — not a signature in their place.
