Guidance On Building Performance Requirements And Materials

Performance Requirements for Plumbing, Roofing, and Fire Safety

Question 1

States that objectives are set according to the community expectations, the functional statements need to show how the building meets its objective, performance requirements should establish how building elements would achieve the functional statements and objectives and the building solution.

Question 2

I would follow the requirements of performance that direct the least level of performance for the plumbing, buildings and drainage installations. The requirements of performance, as well as the general supporting requirements, are the main code requirements. Masonry accessories have a satisfactory performance requirement if considered in installation and construction in either the AS 4773 or AS 3700.

Question 3

The standard has execution, specification and control earthwork testing guidance and is associated with residential and commercial site preparation developments. In itself, it does not constitute earthwork specification and with the specifier considering the project guideline applicability.

States the roofing needs protection from debris as well as loose materials in the process of construction. Also, there needs to be the allocation of thermal movement in the process of installation. A movement should be in joints as well as fastenings. There has to be the material separation between incompatible materials. Cleaning should be done to remove any foreign materials.

Question 4

• Formulation of performance solution whereby there is a combination of one or more of; verification method, suitability evidence, comparing the deemed-to-satisfy method to the performance solution and expert judgement.
• Use of Deemed-to-satisfy solution by using a combination of these two; expert judgement and suitability evidence.
• Combining the deemed-to-satisfy solutions with performance solutions.

Question 5

Use of recycled materials, use of steel construction materials and the use of dry but light materials.

Question 6

The requirements leading to satisfaction of the deemed-to-satisfy involve complying with;

• Resistance from different combined actions.
• Determining of individual actions.
• Determining the material structural resistance and construction forms.
• Resistance to loads such as live loads. Dead loads and combined loads.

Question 7

Levels of fire resistance are to be graded according to the specifications of the type. In type A, the following order of criteria has to be followed in fire resistance construction;

• Structural adequacy.

In addition to these, the certifier has to issue an approval document with necessary schedules of safety measures, lists, occupation certificate, determinations, and certificate of classification as well as the certificate of compliance. An issuance of these documents allows rating of elements of safety in the fire. Non-compliant buildings have to be nominated in logbooks of safety measures for annual statements.

Question 8

Structural adequacy where the structure’s ability to maintain the capacity to bear load and stability after testing is determined. The structure is deemed to fail if there is a collapse of the element or if the element has deflection rate that is excessive to the prescribed limits.

The integrity that entails the door’s ability to keep off flames as well as hot gases if tested to these specifications. Failure is deemed when flaming occurs continuously on the side of the door that is not exposed. Also, failure occurs when openings exist allowing flames to reveal themselves.

Building Materials and Fire Resistance

Insulation whereby a door could maintain the temperature to a specified value below the limit on the exposed surface to flames if tested accordingly. It is deemed to fail when temperature from a side that is not exposed riding to exceed the predetermined value.

Question 9

An active determination is assessed by the installation or presence of communicating, detecting and smoke control devices that could inform instances of the outbreak of fire. This is a proactive way of extinguishing the fire. Such devices include;

• Fire Break Glass Alarm.
• Usable fire extinguishers.
• Thermal and smoke detectors.

A passive determination is assessed by the full-scale test of an incorporated structural system with the protection against fire by evaluation of the effectiveness of materials used for protection. There are numerous methods used in the method that include;

• Timber encasing.
• Concrete filling.
• Flame shields.

Question 10

Every individual solution has a unique performance solution. The solutions used are usually flexible in attaining the outcomes together with the used technology. Solutions in performance would directly address the required performance by the use of one or any other recommended method of assessment.

An alternative solution is known as the solution in the building that would comply with the required performance as well as satisfying the provisions put in place in the deemed-to-satisfy criterion.

An example that falls under alternative solution is hinged-do0r automation. This method allows the provision of better solutions in building and allows the provision of greater accessibility levels for users in the concerned building.

Question 11

• Three drawing copies of that show the floor plan for each level, sections, elevations, sizes, dimensions and scaled structural member locations.
• Three specified copies describing the methods and materials that are to be used for constructing.
• The use statement or the intended use of the building to be indicated on the plan allotment.
• Three allotment plan copies that are scaled to not less than 1:500 or any other approved scale that show the set sub-regulations.
• Report or computational copy demonstrating the building‘s construction of compliance.

Question 12

Documents of submission as well as approval plans, duties of the site supervisors, and construction builders, a design of the building and its construction, installation of the building’s exterior features, the building’s occupation and miscellaneous features included.

Question 13

Detail drawings, component drawing, block plan, assembly drawings, floor plans, site plans, scale drawings, perspective, technical drawings and concept drawings

Question 14

In multiple classifications, every building’s part has to be categorized separately as follows;

(i) situations of parts with various purposes — if the area has a floor area that does not exceed the 10% area, the minor use falls under a different classification while the major use classification would apply for the remaining building.
(ii) The provisions of a situation (i) fail to apply in case the minor use of the building’s section is a laboratory or classes 3, 2 or 4.(b) Machinery rooms, plant rooms, lift room, and many more of such criteria should have a similar classification in the building’s part of an area of construction.
(c) A building comprising of various classes has its parts complying with all the regulations and provisions for the various classifications.

AS Standards for Residential and Commercial Building

Question 15

The volume contains provisions that are general to the interpretation, application and operation that are to be dealt with in the construction of buildings. It includes the use of alternatives that would be deemed-to-satisfy to the provision of accreditation of certificate, there is also the use of performance requirements in the process of construction and design.

Question 16

• verification method using computer system and application
• evidence of suitability as per NCC codes
• Experts judgement of the compliance of building solutions with performance requirements
• comparison with dts provisions
• use of documentation and other supporting evidence

Question 17

Materials used in the building are determined by the class of building which predicts the structure toughness required. Materials are also influenced by the environmental conditions that are available across the year. The ease of access to these materials also affects its suitability as well as the cost.

Fire resistance and building materials

Materials used should be having high limits that would lead to fire occurrence as well as leaving less space for flame passing on them. The exposed side should have the capability of preventing the fire from reaching the non-exposed side for longer durations.

Question 18

AS 2870 classifies the design, site and construction of single dwelling house residential and footings or a structure that is similar having separate or detached common wall. These dwelling need not be vertically below or above another. Residential slab and footings

AS 1684 covers the building practices, design criteria, bracing, tie-downs and span tables used in timber framing. Residential Timber Framed Construction

AS 3700 provides a guide to the good practice of the materials required, workmanship, temporary bracing, tolerances, compliance assessment and testing of site control. Masonry Structures

AS 2050 involve the requirement in roofing of buildings during the design and maintenance as well as construction.  Roof Tiling

AS 2047 entails the assertion of the least requirement in the compliance certificate on the warranty, members participatory accreditation, commission to the code of conduct and the meeting of requirements needed. Windows and doors

Question 19

• Beam performance.
• Columns performance.
• Roof trusses performance.
• Loading and loads.
• Behavioural structure of materials.
• Force system solutions.
• Property sections.

Question 20

1. Stress and strain – when stress and strains were being experienced by a structure orstructural materials they may break, be destroyed or be deformed. However, if the
   materials used in building and construction was chosen based on the risk of the building
   being exposed to stress and strain then there is a good chance that the structure and
   materials may resist these forces and maintain their form. The use of foam and other
   cushioning materials may help to achieve this goal.
2. Compression – compression may cause flattening and deformation to certain materials and when that happens that may result in loss of purpose and function of that material
   that may cause risk to the stability and formation of the building.
3. Bending – Bending may cause damage to the materials, for example, the foundation of the
   building may collapse if there is an earthquake because it is unable to resist force from
   the disaster.

Question 21

Fabric

They include the circular yurt that was revived with the use of developed tensile architecture as well as the synthetic fabrics. Properties include water resistant and termite proof.

Rock

It is easily available and is the longest-serving building material with heavy density making it withstand great compressive forces. Difficult to keep warm unless great resources.

Concrete

Consists of aggregate and binder composition. Has great compressive and tensile properties hence used in the strengthening of steel rods.

Question 22

COMPLIANCE LEVEL in the required performance commands the least performance level for every building as well as the drainage and plumbing installations.

Alternative Building Materials

The required performance set the performance level that has to be reached by the complied solution.
COMPLIANCE SOLUTIONS involve solutions that are ways to attaining satisfactory performance in requirements. There is a provision of various approaches that include; deemed-to-satisfy, performance solution or combining both solutions. This would give way to flexible and satisfactory requirements of performance.

Deemed-to-satisfy methodology make us of the provisions in it to make references to the documents that ascertain the regulations involved.

Provisions of such manner include prescriptive products, materials, design factors, installation methods and construction examples that follow in full the compliance with requirements of performance.

Any solution that would meet the requirements of performance other than a solution of deemed-to-satisfaction is a performance solution. These performance solutions could differ in part or whole from the provisions of deemed-to-satisfaction that would realize the performance requirements. This is only so if there is a successful demonstration of the method of achievement.

Question 23

• Provision of facilities

Employers have to provide ample toilet facility access to each worker during their presence at the workplace. These facilities have to be readily available. The toilet facilities have to be conveniently provided taking into consideration the building’s use, the gender and number of occupants as well as the needs or disabilities that may be present in every individual.

Washing facilities have to be provided. Facilities such as washing basins need to be issued by the employer or availed with ease thereby allowing easy washing. These washbasins need to be separated from troughs or sinks.

Rest areas should be provided with the consideration of the nature of work being done. More considerations on this facility are the number of workers as well as the appropriateness of the area of rest. Facilities such as restrooms could be put in the same location as first aid room. Workers conducting work in isolation will have to be given access to emergency devices of communication. S

• Drinking water

The employer has to provide an adequate amount of drinking water that is readily available to the employees. The points of access have to be of good hygiene and not near toilets.

The drinking water temperature has to be below 24⁰C achievable by refrigeration or providing ice that would cool the water. The pipes that supply drinking water would have to be protected from direct sunlight to avoid heating up.

Water being supplied would have numerous points of access hence there would be the need to label these points as per their use.

• Clothes and changing facilities

Changing rooms would have to be provided to facilitate the change of clothing before and after work. In instances that workers may be exposed to the hazardous environment would require the provision of protective gear. These protective gear would then be contaminated after use. Also, these changing rooms would need to be constructed to allow storage of clothing required for work with proper storing conditions in accordance with the types of work.  

Active

• The position of the device.
• Sensitivity
• Hierarchy of action of the device.
• The number of devices.
• The response of the device.

Passive

• Length of the device such as hose reels.
• Location of the device.
