Design calculators
Alliance Resolve Limited has developed a range of practical design calculators to support surveyors, retrofit professionals, designers and other competent practitioners in carrying out routine technical assessments more efficiently and consistently.
The purpose of these calculators is to aid and assist the design process by simplifying repetitive calculations, improving consistency and reducing the administrative burden associated with preparing competent designs. They are intended to provide a structured starting point for technical decision-making and to help users identify the key parameters, design criteria and potential areas requiring further consideration.
The calculators are not intended to replace professional judgement, competent design, site-specific assessment or detailed verification. They should not be relied upon as a permanent or final design solution without further review.
Building design is inherently project-specific. Construction type, existing defects, occupancy, environmental conditions, interfaces between measures, manufacturer requirements, statutory guidance and site constraints can all materially alter the suitability of a proposed solution. For this reason, the outputs generated by these calculators should always be reviewed by a suitably competent person before being incorporated into a specification, design, installation or compliance submission.
Used appropriately, the calculators can help to reduce the burden of repetitive design calculations, provide a clearer audit trail and allow the competent designer to concentrate greater attention on the areas that require professional judgement, coordination and technical scrutiny.
In effect, the calculators should be regarded as professional design aids rather than substitutes for professional design.
Alliance Resolve Limited accepts no responsibility for the use of calculator outputs as a final design without appropriate independent review, verification and consideration of the particular circumstances of the project.
