The series is the Swiss Engineers and Architects SIA is important for the construction industry, even if his application is voluntary and not in every work contract will automatically become part of. Of clear rules vendor and the purchaser will benefit equally, so that is now little more without reference to the standards advertised or offered.
Building is a process that is changing very fast. New techniques. new materials and changing demands, therefore, require constant adjustment, even with the standards.
Important changes
The SIA 343, doors and gates, has undergone a last adjustment in 1990 and has now been brought up to date. In force since 1 March 2010 Norm plant has experienced a remarkable freshening up. Involved were also European standards. Already important in the classification changes are visible: So was the old Standard in a technical and an organizational part broken.
The new plant consists of two different standards. The SIA 343 deals exclusively with the technical processing.
for the organizational division of the Commission with the SIA 118/343 a separate set of rules has created, which deals only with the contract terms. The main changes are to be found in the tender and the remuneration. It sets the standard high value on extensive and detailed information in the tender documents. In addition to appropriate plans, the contracting authority is obliged to draw up a detailed door schedule.
This relieves the providers already in the tender phase. With a list will constitute the most important data easily and clearly. So far, the processing of the data and the creation of such a list was mostly by the contractor. Entry errors could be difficult to correct without additional effort.
disengagement plan
The new standard required by the contracting authority planning much more preparatory work. Steps are necessary to the configuration, the function must be defined. These include the usability, operability, access control and much more.
Also, the Planning and ensure management of interfaces to door, alarm systems and power supply is no longer due business side. So much expertise is transferred to the contracting authority.
this measure is likely to preferred companies, which have been little concerned with doors, because the planning of complex objects has been simplified with the relocation. Companies with high expertise can advise or assist the planners to take those same mandates.
The transfer of competencies, and thus even at the tender specifically defined requirements, there is a better comparison of the offers. For this may but the settlement of multi-services come easier because the required performance characteristics must be described clearly.
sealing must be
For the first time held the term driving rain in a standard door entry. As part of the requirement distinguishes the classes of rules between unprotected and protected doors. The latter have depending on their location, the class 1B to 7B, and 7B, a test pressure of 300 Pa. Unprotected elements must correspond to the classes 1A to 9A. For the manufacturer of doors is so important that he knows if his door directly weathering of exposed or not.
alignment VSSM-uses
Significant changes were made in the remuneration. This allows companies to get this effort for Abklärengen for special, requiring authorization security doors reimbursed if it were not already fixed in the invitation.
The transfer of many others, usually including a suspected efforts are now clearly defined. such as scaffolding and preparatory work in steel frames. Especially with the installation of steel frames, it pays to know the standards. They define as many details well what is superfluous in many future discussions.
course, the standard applies only when nothing else is described in the work contract. The creation of the reports and the speedy sight but by the construction management should facilitate the transfer. The settlement of the contract sum has been adapted to VSSM-uses. So new is due with the order 30% the price of work. Another 30% is due at delivery and another 30% after installation. The remaining 10% is the entrepreneur after the fulfillment of all contractual services and after the audit period benefit.
also these rules apply only. has been adopted in the work contract does not otherwise control. The new rules create: in many areas of clarity and certainty for operators as well as for building owners and architects. It creates: but also clarity in the offer. ie, clients will be able to evaluate the various offers better in terms of price and performance. The bottom line seems to have evolved a favorable set of rules.
