Three core phases that run the same way on every project – plus early stage, sale and operation for developers and portfolio holders. For new build and retrofit, from single-family homes to apartment blocks.
Start with the work you need and expand when required. Building quantities, services, prices and durations stay connected, from the first decision through construction.
Shared foundation: building data, documents and collaboration connect the modules. Invited participants collaborate for free within their project role; independent professional editing requires the appropriate modules. Collaboration is not an additional module.
AFTER CONSTRUCTION
Keep using project data for technical operations and marketing. Availability follows the respective offer.
The complete feature overview: from portfolio and early design through costs and procurement to delivery. Module groups also cover bid costing, the 3D offer room and subcontractor management. Choose a topic for your role; each module explains its scope and availability.
A shared building model gives you more than an overview: it forms the basis for calculations, tendering and construction schedules.

From trade down to individual line item – works on five levels, drawn from 20 trades plus design and project support. Automatically linked to the building data. With suggestions, alternatives shown explicitly and dependencies checked automatically – meaning clear packages for clients and less back-and-forth for professionals. When a project involves many trades or a large volume, Renaldo automatically suggests matching design and support services in the basket.

GEG check, funding & measures – in one place.
The “Energy advice” page brings together everything you need to know about your retrofit, matched to your building data: a GEG check against German building-energy law (U-values, efficiency-house levels), a funding check covering BAFA, KfW, federal-state and municipal schemes, and a recommendation of measures. Renaldo checks which programmes apply and keeps an eye on the deadlines for you.

Gaps and pricing risks, visible immediately.
Analyse bids one by one or side by side – Renaldo shows missing items, unusual prices, risky clauses and differing specifications at a glance.
Turn your design work into a binding fee proposal – awarded online.
Professionals produce a complete proposal per project, contract terms included – built from Renaldo service modules or on the German HOAI fee scale, with prices pre-filled and a payment schedule. Via the basket, those costs land straight in the client's budget. The client sees the proposal through an email link without logging in, and awards the work online.

From initial scenarios to supporting evidence: connect funding plans, offers and invoices to your construction project. Prepare the information needed for professional review and funding decisions.
↗
Compare scenarios
Calculate funding options from the project and its measures, refine assumptions and adopt a scenario. Reconcile the selected funding approach with the cost plan.

Check offers and invoices
AI-assisted checks examine offers and invoices for funding-relevant information. Missing evidence and technical questions are highlighted for further review.
↗
Track applications and evidence
Applications, documents, deadlines and reminders stay with the project. Keep track of missing evidence and the next action.
A prepared starting point reduces repeated data entry, especially in renovation. RENALDO connects the building model, room schedule and draft drawings. Your designer receives the model via IFC, reviews it and develops the architectural design and subsequent planning.
Start with the existing building
Available LOD2 building data and a hypothetical room schedule provide an initial model. Existing drawings, surveys, scans or IFC data refine that starting point.
Hand over the full model
IFC4 export includes the components present in the model: walls, slabs, roof, stairs, windows and doors, plus spaces, quantities, materials and properties. Draft drawings from the Planning Center support the handover.
Review and develop the design
The designer checks dimensions and existing conditions, adds a measured survey where needed and makes the final architectural adjustments. Professional planning builds on the early design.
LOD2 and a hypothetical room schedule are early design assumptions, not a measured survey. Spaces without a known location remain records without invented geometry. The designer checks import and editability in the chosen CAD system and remains responsible for professional review and approval.
Module: Plan & Calculate. File handover follows the project release rules for plans and data exports; a trial alone does not unlock IFC downloads. Housing and homeowner project and package rules apply.

01
Packages from the client’s bill
Find suppliers, send invitations with preview, collect offers – with the tender’s item numbers, short and long texts. Requires bid costing and Tender & Bill, both included in the contractor package.
02
Margin per item
The comparison sets subcontractor offers against your bid to the client – per item number and as a package total. The benchmark exists before the first subcontractor bid: costed from the Renaldo market price, real contractor prices with a regional factor.
03
Award and keep building
The award stores the package specification as the contract basis. Schedule, variations and invoice checks continue in the same project.
04
All subcontractors in one place
Every company from your projects with required certificates and expiry reminders, a company check via North Data and insolvency notices, figures such as award rate, variation rate and schedule reliability, and ratings after acceptance. Favourites and the block list apply to the whole organisation. This part can also be booked without the contractor package – by consultants, developers and housing companies.
