What kinds of work does Lianta cover?

Building alterations, partitions, doors, finishes and specialist building services, through to coordinated installation and handover for hotels, restaurants, shops and warehouses. Tell us your trades, region and the work you want to take on.

Do we still control our quotes and commitments?

Yes. Your team sets prices, resource availability, scope and commercial terms. Lianta prepares the working information and highlights unanswered questions; your authorised people decide what to offer and accept.

What if the site is not ready?

Lianta makes the missing requirement visible and brings it to the responsible company. Your team can agree a revised sequence or date with the client and other specialists, keeping additional cost and programme effects in the record.

Can we use it on a project we already have?

Yes. Bring your existing client, project and team. You can start with a current coordination problem or a work package; you do not have to wait for a new enquiry through Lianta.

Can Lianta help with the paperwork needed for payment?

Your AI team gathers progress records, variation details and the supporting documents required by your contract. It helps track missing information and submission dates so your team can review the application or invoice before it is issued.

Can a main contractor use Lianta for its own projects?

Yes. Bring your client, project and trusted subcontractors. Your company can commission Lianta for an agreed paid coordination scope. Invited contractors and suppliers receive basic AI support free for that project. Your appointed people retain site, technical and contractual responsibilities.
