EXCLUSIONS & ASSUMPTIONS
1. The Company cannot be considered to be, nor assume the role and any liability associated with the role of an architect and/or building/façade engineer on the basis of the Company providing the Design and/or the Design Services.
2. The Quotation, Order and any Design, Design Services and/or design proposals are based on the requirement that all design supplied by the Company will be subject to approval and/or instruction to proceed via a stakeholder transmittal loop.
3. The Services are based upon drawings and information presented directly to the Company. Unless specific drawings or areas have been highlighted to them prior to the issue of the Quotation Order, the Company will not consider assumed access to drawing portals and/or any other electronic data rooms as being ‘information presented’ and the Company will not be liable for any failure for the Services to respond to drawings or information not presented directly to the Company.
4. The Company assumes that any primary structure (including the structural frame and infill framing) has been designed by the Buyer and/or any other third parties to take the subsequent loads applied by the Company’s products. Fixings and anchors will be designed by the Company to interact with the structure into which they are installed. Fixing designs will be issued to the project design team for comment and/or approval prior to the supply of product. The project engineer (or relevant professional consultant) must satisfy themselves that the structure is capable of supporting or restraining the imposed loads transferred to the structure by the support and restraint products supplied by the Company and the Company will not be liable for any default in respect of the same. Although the Company can advise on the correct specification and installation of fixings and anchors, responsibility (and liability) for the design, specification and installation of the structure rests with the Buyer and the project design team but (for the avoidance of doubt) not the Company.
5. Design calculations will be produced to gauge and assess the mechanical performance of the rain screen framing system which will include the design of the rails and number and position of brackets and fixings. As part of this process a wind load assessment to EN 1991-1-4+UK NA is used for the inputs and evaluation of the mechanical design of the rainscreen framing system only and is not intended to preclude the need for or supersede the project designers wind load assessment of the envelope or building as a whole. Both the design inputs and resulting designs must be checked by the project design team against the specific project requirements to assess the suitability of the resulting design. The approach followed ensures a conservative assessment where the following assumptions have been made:
• The influence of higher neighbouring structures (EN 1991-1-4, Chapter 4.3.4) to determine the wind load is not considered.
• The influence of closely spaced buildings and obstacles (EN 1991-1-4, Chapter 4.3.5) to determine the wind load is not considered.
• The building area C is not considered.
• Any restraint in the sub-structure due to temperature changes must be considered separately.
• The loading of the 1st layer profile is assumed as an equally distributed load. In case of h/d > 5 the external pressure coefficients for the case h/d = 5 will be used.
• The external pressure coefficients are conservatively assumed as local coefficients. Local coefficients give the pressure coefficients for loaded areas of 1.00m².
6. The Buyer is required to provide all relevant information (including the Buyer’s Design) so as to allow the Company to provide the Design and/or Design Services and the Company is entitled to use and rely on such information. In the event that any and all relevant information required to provide the Design Services is not provided by the Buyer to the Company on enquiry, the Company shall be entitled to (and the Buyer accepts the Company’s entitlement to) make assumptions about such information so as to proceed with the Design and Design Services, including to enable the Company to evaluate the theoretical loads to be supported & restrained by the Company’s products, with such assumptions subject to the following standards:
• British & European Standards, Codes of Practice and Regulations current at the date of specification.
• The standard of skill and care reasonably to be expected of a competent designer experienced in provision of services similar to the Design and/or Design Services and making assumptions set out at clause 4 above.
7. The Company does not provide any warranty whatsoever and does not assume any liability with respect to the complete through wall system and associated interfaces with other products or systems or its overall function as a façade other than for the Goods supplied by the Company to the Buyer. It is for the Buyer’s design team to check and approve that the Services meet with the specific requirements of the Project.
8. The Company has no liability whatsoever to the Buyer or any other party in respect of the installation of the Goods into the Project. The Buyer must appoint a contractor who is certified to install the Goods.
9. The brick units as specified and procured by the Buyer or the Buyers Client are supplied free issue to the Company for cutting and grooving as required by the Company for inclusion within the panels. The Company will provide an estimate of the quantity of bricks required including a percentage to cover the typical wastage for breakages during transit and cutting. The Buyer is responsible for covering any additional requirements if the yield is less than estimated due to brick type, quality, or damage to bricks prior to cutting.
10. All stainless steel will be quoted and supplied in grade 1.4301 (304) unless the buyer instructs the company that a higher grade is required for aggressive environments or applications below DPC level for example where a higher grade should be specified.
11. The rate quoted excludes:
Installation, pointing mortar, insulation, bricks units (UNO), wastage (UNO), brick blending, flashings, fire stops, cavity trays, weep joints, vapour barriers, sealants, work/design drawings (priced separately if required), take off (priced separately if required), project specific testing, site surveys and/or measures, disposal cost for removing packaging materials.
SUPPLEMENTAL NOTES
• Quote is valid for 30 days from the date of issue found on page one of this document.
• Budget quotation is based on a take-off of the areas as detailed within this quotation.
• Brick type, bond pattern and module sizes are not yet confirmed so designs may vary depending on project specific design variables and requirements. This may affect the budget rate quoted.
• The cost of the brick (where included) is estimated in the quote but factors such as wastage due to cutting may affect the final rate.
• The framing system is included in the rate but will be subject to full design following the receipt of an order so the final rate may change.
• Carriage is charged on all orders. If carriage is not shown on your quotation this may be due to the absence of a desired delivery date; please do not assume that no carriage is chargeable. Carriage will be charged at cost at time of despatch.
• The Company prides itself in being the fastest manufacturer in the industry; however, please ensure you agree any critical due dates in advance. Where goods require Client / Architect / Engineer approval, any delays by these third parties will impact on the Company’s predicted Delivery Date.
• All products designed and subsequently supplied by the Company are covered by various insurances and indemnities. Details of these safeguards are available upon request.
