THE DOCUMENT IS CALLED ‘SANS 10400 PART XA: ENERGY USAGE.THIS AMENDMENT HAS TO DO WITH THE ENERGY THAT A BUILDING LOSES AND HOW MUCH ENERGY IT CAN GENERATE AT THE SAME TIME. THE BUILDINGS ARE THEN RATED ACCORDING TO HOW FAST AND HOW MUCH ENERGY IT LOSES THE AMOUNT OF ENERGY LOSS NEEDS TO BE MAINTAINED AS TO NOT ALLOW FOR THE BUILDING TO LOSE MORE ENERGY THAN IT IS PRODUCINGTHIS AMENDMENT REQUIRES THAT ALL NEW BUILDINGS IN SOUTH AFRICA ARE TO MAKE USE OF SOLAR WATER HEATING, HEAT PUMPS OR HEAT RECOVERY SYSTEMS TO HEAT AT LEAST 50% OF THE BUILDINGS HOT WATER SUPPLY
  • ARCHITECTS ARE TRAINED INDIVIDUALS WHO DEVELOP CONCEPTUAL IDEAS FOR BUILDINGS AND STRUCTURESMTHEN TURN THOSE CONCEPTS INTO THE DESIGNS AND PLANS THAT ARE USED TO GUIDE THE BUILDING PROCESS.THROUGHOUT THIS PROCESS, ARCHITECTS TAKE ON A NUMBER OF DUTIES AND RESPONSIBILITIES:ARCHITECTS ARE EXPECTED TO HAVE A REASONABLE WORKING KNOWLEGDE OF THE LAWS AND LEGISLATIONSGOVERNING DESIGN AND BUILDING WORKS. THE ARCHITECT HAS TO ENSURE THAT HIS PLANS COMPLY WITH THEACTS AND REGULATIONSSOMETIMES DUE TO THE COMPLEXITIES OF SOME PROJECTS, THE ARCHITECT WILL USUALLY DELEGATE A LARGEAMOUNT OF THE TECHNICAL ASPECTS OF A DESIGN TO OTHER SKILLED PROFESSIONALS SUCH AS MECHANICALAND ELECTRICAL ENGINEERS, CIVIL AND STRUCTURAL ENGINEERS, QUANTITY SURVEYORS, ETC, AND SHOULDTHEN INFORM THE CLIENT OF THIS.DESIGN RESPONSIBILITIES OF AN ARCHITECT CAN RANGE FROM THE AESTHETIC DESIGNS OF A BUILDING TOSPECIFICATIONS, SELECTION OF FINISHES, AND THE CHOICE OF CONSTRUCTION TECHNIQUES. THE ARCHITECTMUST EXERCISE SKILL AND CARE IN THE EXECUTION OF HIS DESIGNS AND IN THE CHOICE AND SPECIFICATIONOF MATERIALS
  • THE ARCHITECT HAS TO HAVE A HIGH DUTY OF CARE TO HIS EMPLOYER TO ENSURE THAT HIS DESIGN IS SUITABLE FOR THE PURPOSE MADE KNOWN TO HIMTHE ARCHITECT IS TO OBSERVE AND INVESTIGATE THE SITE TO DETERMINE WHETHER THERE ARE ANY PHYSICAL CONSTRAINTS WHICH MAY AFFECT THE SITE OR BUILDING. HE SHOULD ALSO OBTAIN PLANS FROM THE LOCAL AUTHORITIES SHOWING ANY PLANNING CONSTRAINTS. IF THE ARCHITECT DOES NOT HAVE THE SUITABLE EQUIPMENT TO CONDUCT A PROPER SITE INVESTIGATION, HE MUST ADVISE THE CLIENT TO MAKE USE OF A SUAITABLE PROFESSIONAL SUCH AS A LAND SURVEYOR, ETC TO CONDUCT THE INVESTIGATIONAN ARCHITECT IS OFTEN ASKED TO PRODUCE A DESIGN WITHIN A GIVEN BUDGET, AND IN THIS CASE, THE ARCHITECT MAY BE UNDER A DUTY TO DESIGN WORKS CAPABLE OF BEING CARRIED OUT AT A REASONABLE COST, WHILST CONSIDERING ITS SCOPE AND FUNCTIONTHE ARCHITECT HAS THE DUTY OF RECOMMENDING THE FORM OF CONTRACT TO BE USED TO HIS EMPLOYER, ENSURING THAT HE IS FAMILIAR WITH THAT FORM OF CONTRACT AND IS ABLE TO ADMINISTER THAT CONTRACTTHE ARCHITECT IS TO ENSURE THAT THE PLANS, DRAWINGS AND DETAILS ARE ISSUED TO HIS EMPLOYER AND THE CONTRACTOR WITHIN A REASONABLE TIMEIT IS ALSO THE DUTY OF THE ARCHITECT TO SUPERVISE THE BUILDING WORKS FOR WHICH HE/SHE HAS DESIGNED, ENSURING THAT THE BUILDING WORKS ARE CARRIED OUT ACCORDING TO THE PLANS, SPECIFICATIONS AND THE FORMS OF THE BUILDING CONTRACT, AS WELL AS IN ACCORDANCE WITH THE ACTS AND REGULATIONS.

  • THE BILLS OF QUANITITES IS THE MOST COMMON FORM OF PRICING STRATEGY USED WHERE THE CONTRACTOR UNDERTAKES CONSTRUCTION ON THE BASIS OF FULL DESIGNS ISSUED BY THE EMPLOYERTHE BILLS OF QUANTITIES IS SOMETIMES ALSO REFERRED TO AS A ‘SCHEDULE OF QUANTITIES’ AND IS A LIST OF ITEMS AND ITS MEASURED OR ESTIMATED QUANTITIES AS WELL AS A BRIEF DESCRIPTION OF THE WORK TO BE PERFORMEDUNDER THE CONTRACT. THE QUANTITIES AND DESCRIPTIONS ARE DETERMINED AND MEASURED FROM DRAWINGS AND SPECIFICATIONS
  • THE BoQ HAS TWO PURPOSES: THE USE OF A BoQ ON CONSTRUCTION CONTRACTSo PRESENTING INFORMATION TO THE PERMITS 4 IMPORTANT TENDERES ENABLING THEM TO PRICE OBJECTIVES TO BE ACHIEVED: EACH INDIVIDUAL ITEMS AS IT RELATES TO THE DATA STIPULATED IN THE CONTRACT, THE SCOPE OF THE o THE TENDERERS ARE PROVIDED WITH WORK, AND THE SITE ENOUGH INFORMATION REGARDING THE INFORMATION, ALLOWING THE EXTENT OF THE WORK REQUIRED TO TENDERERS TO ARRIVE AT A TOTAL OF ENABLE THEM TO ACCURATLEY AND PRICES CONFIDENTLY PREPARE RESPONSIVE TENDERSo ALLOWS THOSE RESPONSIBLE FOR o TENDER PRICES CAN BE OBJECTIVELY EVALUATING TENDERS TO UNDERSTAND COMPARED AS THEY HAVE BEEN HOW THE WORKS HAVE BEEN PRICED SUBMITTED USING THE SAME INFORMATION o IF ALL THE WORK HAS BEEN MEASURED, EMPLOYERS CAN DETERMINE, BEFORE-HAND, THE COST OF CONTRACTS WITH A HIGH DEGREE OF ACCURACY o THE VALUE OF WORK CARRIED OUT AT ANY STAGE OF A CONTRACT CAN BE OBJECTIVLEY DETERMINED
  • Before any form of building work canbegin, contracts need to be signed andthe building licence approval isobtained. The builder can then beginconstruction on site. After signing thecontract with the builder the architectthen has to administer the contract andassure that the building is constructedaccording to the documents. Thearchitects also signs and certifies anychanges, claims for payment, andalterations during that period. Once thebuilding is completed, the architect is toissues a final certificate which ends thecontracts between the builder andarchitect.
