What the contract does not say gets paid for later.
A well-prepared BIM tender document passes on to each party what the tender requires of you at each phase. Everyone knows what they deliver, when, and how it is checked.
With digital delivery properly in place, design and construction costs fall by 13 to 21 %.

You have to write the BIM tender document anyway. Write it once and make it work for every project you build.
The tender already demands it. You will pay to draft it either way; the gap between doing the minimum and doing it well is small.

of rent for every month of delay on a residence like Granada: 520 studios from €650/month (studentexperience.com), at 95 % occupancy. Far more than writing the BIM tender document properly costs.
The opportunity cost: use the tender only to comply, or as the lever that puts all your Spanish projects under the same rules.
In a residence, mistakes multiply. So do good decisions.
The typical room
A bathroom duct hits a beam and it is found on site. At €300 per room, that is €156,000 and weeks of delay. If the BIM tender document requires the typical room to be coordinated in the model with every trade before construction is tendered, the clash is solved in the model, not on site.
The skirting boards nobody should model
Without a rule, skirting boards, handles and sockets get modelled in 520 rooms, or billed as an extra. With one, only what is measured, tendered or handed over gets modelled. You pay for decisions, not modelling hours.

One day of delay in Granada costs about €10,700 in rent: more than three times this assignment.
"The model will be updated at the end of construction."
"The contractor delivers the as-built model, with data for every piece of equipment, before handover. Site supervision checks it within 10 days against the checklist. It is a condition for signing the certificate of completion."

The council only asks for a level of detail per phase. Your BIM tender document says who produces it, what data it carries and how it is accepted, and puts it in each party's contract.
Four common situations a good BIM tender document settles before they cost money.

Undiscounted, before tax. Writing the BIM tender document (€3,360) is separate and barely changes the result. Each month of delay is valued at lost rent only; financing and overheads would make it larger.
