Costs of construction supervision

We are renovating an old multi-family house in Berlin-Mitte (approx. 700 sqm) with a gross cost of around 1.2 million euros. Planning, building permits, and tender documents are available. Now we are looking for a suitable construction manager and are wondering what percentage of the construction sum we should probably budget for.

Many thanks for answers and recommendations!

Hello,

We are renovating an old multi-family house in Berlin-Mitte (approx. 700sqm) with a gross effort of around 1.2 million euros. Planning, building permits, tender documents are available. Now we are looking for a suitable construction supervisor and are wondering how many percent of the construction sum we should probably budget.

As always, it depends ;)

What level of supervision is desired: should the tender be monitored and checked, should the trades be formally accepted by an expert, or should only the pure site management activity be carried out with how many hours/day/week?

Kind regards

This is what the construction supervisor is to perform: Conducting the tender, analysis and selection of providers, ongoing on-site coordination and supervision, controlling and billing, preparation/support of acceptance, ongoing documentation
