IT support for construction companies: site offices, drawings and the electronic log

An office you will have to dismantle

Construction differs from our other clients in one way that changes every purchasing decision: the workplace has an end date. A contract runs for a year or two, then the site cabin disappears and the equipment has to go somewhere. On top of that come two Polish government systems that now hold the construction log and the building book, plus the question that is most expensive to get wrong in this industry: which revision of the drawing is current.

What you will not find here, although it is often promised: satellite links, drones and RFID equipment tracking. We do not do any of that and will not pretend otherwise. We handle what a construction company uses every day: connectivity at the site office, documentation, people’s accounts and hardware that has to survive the contract.

A site office has an expiry date

This single trait separates construction from every other industry we serve, and everything else follows from it. Whatever you install on site will have to be dismantled, transported and accounted for a year or two later.

  1. Match the connection to the length of the contract

    A fixed line to the site cabin only makes sense when the wait for the connection is shorter than the time it will be used, and on a building site it usually is not. So we start with a router holding SIM cards from two operators, and we check coverage on the plot before committing to anything, because a site on the outskirts may only have signal by the gate.

  2. Put nothing in the cabin you cannot afford to lose

    Site containers get broken into more often than any office, and that is a design assumption rather than pessimism. The server holding documentation stays at head office or in the cloud; what works on site is hardware with an encrypted disk that can be wiped remotely and that is not the only place the data lives.

  3. Closing the contract is a task too

    Equipment from a dismantled site office usually never comes back, because nobody knows who has it. We keep a simple register tying each device to a site and a person, and when the contract closes we collect the hardware, wipe it and prepare it for the next one. This is the cheapest item on this page and the one most often skipped.

Worth working out before any purchase decision: hardware bought for one contract will usually outlast three, provided somebody collects and refreshes it. Consumer hardware from a retail store will not survive the first one, and when it fails there is no on-site warranty. We describe how we choose and bill it on the IT hardware supply page, always at purchase price.

Which drawing revision is on site right now

This is the question whose wrong answer costs the most in this industry, because a finished wall does not undo with a click. The problem is almost never a shortage of storage; it is that there are several places holding the files.

  1. One place with revision history, everything else is a copy

    The usual arrangement is documentation on the office server, a second version in the designer’s cloud, a third in email and a fourth on the site manager’s USB stick. We decide which one is the source of truth, and that is the one that keeps revision history. The rest become read-only copies rather than equal versions.

  2. A subcontractor needs an account, not an email attachment

    Subcontractors need part of the documentation but not all of it, and they usually receive it by email, which means it leaks along with the whole message history. Instead we grant named access to a specific folder with an expiry date. When the crew leaves, access lapses on its own rather than when somebody remembers.

  3. Site staff need to read files, not just store them

    A site manager needs the drawing on a phone or tablet, often on a weak signal. So the current set of documents syncs onto the device and works offline, instead of only opening after logging into the office server through a tunnel.

We neither deploy nor maintain design and 3D modelling software, because those are your designers’ tools and their vendors’ responsibility. We handle where the files live, who can reach them, whether a backup exists and whether they open from site. With large files it is network throughput rather than disk speed that decides, and we set that out on the working with heavy files page.

The construction log and building book now live in government systems

Two documents that were on paper for decades now have Polish government systems: the Electronic Construction Log (EDB) and the Digital Building Book (c-KOB). The deadlines changed in early 2026 and most articles online are now out of date.

  1. Deadlines moved by five years, but not all of them

    The act of 4 December 2025 pushed the issuing of paper construction logs and the keeping of paper building books to 31 December 2031, five years later than before. What it did not touch is what already applies today: for buildings handed over after 1 January 2024 the book is created digitally only, with no paper option.

  2. Once you go electronic there is no way back

    A log kept in the system has to continue there, and you cannot revert to paper after the first entry. That is not an IT problem, but it has an IT consequence: from that moment on, system access and a working signature are a condition of running the site rather than a convenience.

  3. Access is personal and leaves with the individual

    Both systems are accessed with a trusted profile, an e-ID card or through a bank, so the account belongs to a person, not the company. A site manager who leaves takes their means of signing in with them. So we keep track of who the participants are, who still has access, and make sure you are never left with one person without whom nothing can be entered.

An honest caveat: we are not a law firm and we do not keep the log or the building book for you, because those are duties of the site manager and of the owner or administrator. Our part is technical and stops where the content of an entry begins: accounts and sign-in methods for the people who must sign, coverage at the site office so an entry can be made from site, and an archive of documents exported from the systems. A paper book is closed with a final entry and kept for the whole life of the building, so the archive covers both forms at once.

What we do in construction companies

Six areas where work with a contractor or developer most often begins. Each has its own page with the detail.

Documentation reachable from every site

Files in one place with revision history and access from a phone or tablet, without having to connect to the office server every time a drawing is opened.

Cloud solutions

A file server with revision history

For when documentation is to stay with you rather than in the cloud: a file server with snapshots that can roll back an overwritten or encrypted folder.

Synology file servers

Access from site to the company network

A tunnel with a named account and a second sign-in factor for each person, instead of one password circulating around the sites.

Secure company network

Laptops that outlast the contract

Business hardware with on-site warranty repair and disk encryption, configured in batches so a new hire gets a ready device within a day.

Lenovo laptops for business

Estimating software without shipping licences around

Cost estimating and similar programs installed once on a server and used remotely from site. A remote session copes with a weak link far better than working on files through a tunnel.

ThinStuff remote desktop

Hardware to site and back again

Selection, purchase at cost price and a register tying devices to sites, then collection, wiping and preparation for the next contract when this one closes.

IT hardware supply

What we do not do: we do not deploy design software, we do not service construction machinery automation, and we do not run site CCTV or vehicle tracking. We will say so straight away in each of those cases and, where we can, point you to someone who does.

How we start with a construction company

We start at head office rather than on site, because head office is where it is decided who holds the documentation and who can reach it. The site is a consequence of those decisions.

  1. 1 business day

    Where the files actually are

    We list every place holding documentation, USB sticks and private cloud drives included. This is usually the most uncomfortable part and at the same time the one that explains the most. It ends with a single page of risks and it is free.

  2. Usually 2 weeks

    One source of truth and tidy access

    We name the place that keeps revision history, move current projects into it and revoke access from people who no longer work for you. While we are at it we check who is listed as a participant in the electronic log.

  3. Before the crew arrives

    The site office for a new project

    We check coverage on the plot, match the connection and hardware to the length of the contract, and issue devices assigned to that specific site. We schedule the setup before the crew moves in, not during the first week of works.

  4. Contract

    Ongoing support and closing contracts

    Tickets from office and site staff, backups of documentation, and hardware collection at the end of every contract. We write that last point into the agreement, because it never happens on its own.

Questions from construction companies

When does the construction log have to be electronic?

Paper construction logs can be issued until 31 December 2031, and from 1 January 2032 the electronic log becomes the rule. Beware of older articles: before the amendment of 4 December 2025 the cut-off was the end of 2029, so plenty of out-of-date figures are still circulating online. Works on restricted military and security sites remain an exception.

What changed in 2026

What about the building book?

These are two separate matters. For buildings handed over after 1 January 2024 the book is created in the digital system only, and that applies right now. Paper books created earlier may be kept until 31 December 2031, and entries are not transcribed: the paper book is closed with a final entry and retained, while a new book continuing it is created in the system.

Will you help us keep the electronic log?

Not in the sense the question is usually meant. Keeping the log is the site manager’s duty and nobody can take it over, and we are not a law firm. We take on the technical side: sign-in methods for the people who have to sign, coverage at the site office and an archive of documents exported from the system.

Our site manager has left. What happens to system access?

This is the most common headache in the industry, because sign-in to government systems is personal and leaves with the individual. So we make sure there is more than one participant, and we walk through the list of systems one by one when somebody leaves. Worth knowing: a person whose access to the electronic log is revoked may still make an entry for fourteen days afterwards.

Tidying up access

Do we need a fixed line on site?

Rarely, and it usually does not pay off, because the wait for a connection can be longer than part of the contract. The standard is a router with SIM cards from two operators, chosen after checking coverage on the plot rather than from a catalogue. We consider a fixed line for multi-year projects or where mobile coverage is genuinely poor.

How we set up site offices

A laptop was stolen from the site cabin. Is that a reportable breach?

Not always; it is decided by a risk assessment rather than by the theft itself. If the disk was encrypted and the key did not leak, risk to individuals is usually unlikely and no notification is required. If the disk was not encrypted, expect to notify the supervisory authority within seventy-two hours. That is the entire reason we switch encryption on from day one.

What gets reported

We work with subcontractors who are not our employees. How do we give them access?

With a named account to a specific folder, expiring when their works end, instead of sending packages by email. That way you can see who downloaded what, and access lapses by itself once the crew leaves. A shared password to one folder is convenient for the first month and impossible to untangle after a year.

How we arrange access

Do you support sites across Poland?

Yes, because most of this work is remote: accounts, documentation and router configuration do not need us on location. A visit is sometimes needed to set up a site office and we plan it in advance. Outside the Greater Poland region we say plainly how long the drive takes rather than promising same-day attendance.
