Normative Basis
This document does not replace EVS, RYL, legislation, project documentation, or manufacturers’ instructions.
RFP-001 describes the internal House of RAMERK process: how recognised requirements are translated into a sequence of inspections, evidence, and decisions on a specific project.
Applicable EVS standards, including those relevant to the specific facade system; current Estonian requirements; manufacturers’ technical documentation and system solutions; the contract and project; professional practice and RAMERK experience.
Facade Source Register
Purpose
A facade is not accepted on the basis of impressions or promises. It is accepted on the basis of measurements, appearance, and documentation.
RFP-001 translates applicable professional requirements into a process the client can understand. Its purpose is to define in advance how the completed work will be inspected, what evidence must be collected, and when the result can genuinely be considered handed over.
The Three Stages
Facade acceptance consists of three mandatory stages.
Instrumental Control
Inspection of flatness, verticality, joints, interfaces, and other measurable parameters.
Visual Assessment
Assessment of colour, texture, and overall appearance under predefined lighting and viewing-distance conditions.
Executive Documentation
Review of site logs, concealed-works records, material declarations, and confirmation of completed operations.
Measurement Method
Inspection must be repeatable.
Measurements are taken with a calibrated two-metre straightedge and a suitable feeler gauge. Checks are performed vertically, horizontally, and diagonally at representative and potentially problematic locations.
A calibrated straightedge for assessing surface flatness.
Inspection measurements per 50 m² as a practical project guideline.
Where the project, manufacturer’s system, contract, or applicable standard sets stricter requirements, the stricter requirement applies.
Rendered Facades & ETICS
An ETICS/rendered facade is assessed as one complete system, not merely as the final decorative coat.
| Control point | Working criterion | Meaning |
|---|---|---|
| Surface flatness | up to ±5 mm / 2 m | Maximum gap or local high spot beneath the straightedge. |
| Single-storey verticality | up to ±5 mm | Guideline for heights up to 3 metres. |
| Building verticality | up to ±15 mm | Guideline for a building approximately 10–12 metres high. |
| Corners and reveals | up to ±4 mm / 2 m | Deviation of a line from vertical or horizontal. |
| Reinforcing layer | according to the system specification | The mesh is embedded within the layer; thickness and overlaps comply with the system. |
Ventilated Facades
For a rainscreen facade, joint rhythm and the precision of adjacent elements are especially important.
Permissible edge offset between adjacent panels as a practical guideline.
Deviation from the specified joint width.
Deviation of the substructure spacing from its design position.
Joints must read as one continuous straight system.
Visual Assessment
Appearance is assessed under normal conditions of use, not under artificially created raking light.
Appearance Criteria
Hand-applied work allows natural micro-variation. It does not allow a visible systematic defect.
| Feature | Accepted | Not accepted |
|---|---|---|
| Render texture | Minor local differences not visible from the specified viewing distance. | Pronounced areas of differing texture that read as patches or bands. |
| Colour and tone | A visually uniform facade appearance. | Transitions, patches, and scaffold-joint marks visible from the assessment distance. |
| Fixing locations | Do not stand out across the facade surface. | A pronounced “leopard-spot” effect. |
| Panel joints | An even and consistent rhythm. | Broken lines and visible curvature. |
Executive Documentation
Anything that cannot be seen after completion must be verified before it is covered.
Hidden Works
Concealed work becomes reliable only when it is inspected before it disappears from view.
Material Evidence
Every material must have a traceable origin, defined purpose, and confirmed system compatibility.
The handover package must make it possible to identify which products were used, which system they belong to, and which characteristics were declared by the manufacturer. For critical materials, markings, batch numbers, or other available identification are recorded.
Defect Record
A defect is recorded so that it can be located, verified, and closed out.
Locate
Facade, gridline, storey, room, or area coordinate.
Describe
Type of deviation, size, method, and observation conditions.
Evidence
Photograph, measurement, reference to a project requirement, or system document.
Close
Correction method, responsible person, deadline, and reinspection.
Acceptance Decision
A signature means the result has been verified, not merely viewed.
If a visible defect can be distinguished from the specified viewing distance, or an instrumental measurement exceeds the agreed requirement, the issue is recorded before the final acceptance document is signed. Acceptance may be full, conditional with a correction list, or deferred until significant deviations are resolved.
This edition is an internal House of RAMERK standard. The final criteria for each project must be aligned with the project documentation, contract, manufacturer’s system, applicable regulations, and supervision requirements.
House Promise
RFP-001 exists neither to appropriate other parties’ standards nor to find grounds for refusing acceptance. It exists so that applicable requirements are understood in advance, inspections are repeatable, and care for the client’s request is given a technical form.
