PLAIN-WEAVE FABRIC: In plain-weave fabric the warp and weft are aligned so that they form A simple criss-cross pattern. Plain-weave is strong and hardwearing, so It's used for fashion and furnishing fabrics. TWILL-WEAVE FABRIC: In twill-weave fabric the crossings of weft and warp are offset to give a Diagonal pattern on the fabric surface. It's strong, drapes well and is Used for jeans, jackets and curtains. SATIN-WEAVE FABRIC: In satin-weave fabric there is a complex arrangement of warp and weft Threads, which allows longer float threads either across the warp or the Weft. The long floats mean the light falling on the yarn doesn't scatter And break up, like on a plain-weave.The reflected light creates a Smooth, shiny surface commonly called

c)Comment On the use polymers in construction giving examples of their use and describe The problems presented by the use of polymers in the event of a fire.

Answers 5 c):

Polymers are more common in the Construction industry than ever before and composite materials can offer good Strength to weight ratios as well as good levels of durability. GRP can offer alternative Bridge design options, particularly in remote areas where large section can be Flown in by helicopter and erected in shorter time periods. Other examples Include:

  • Window frames – UPVC

  • Rain-water goods – UPVC

  • Waste systems – UPVC / ABS

  • Glazing – Acrylics

  • Cold-water cisterns – Glass reinforced polyester

  • Cavity insulation – Polystyrene bats

  • Sealants are specified with a movement

3.Hierarchy: Achieved by determining dominance or emphasizing one design element over another.  In some cases, it's obvious which elements need to be most dominant. The designer will arranged order by controlling size, placement, color and balance of these elements. Important that one element be dominant to give the viewer focal point.


Balance - Symmetric
- similar design elements are aligned in an equal way on either side of a vertical axis.
- more formal
- often achieved by balancing positive with negative space or form with counter form
Balance - Asymmetric
- unequal arrangement of elements
- look more casual
- achieving asymmetrical balance is more difficult because the visual weight of each element and their arrangements need to be carefully

INTRODUCTION What Is a project (definition, brief description)? A project it is a single, Complex,, unique task, that is limited in costs and time, and has predefined Goals, and assigned sources. It starts from an idea that´s needs to be prepare And plan, be performed to achieved a goal in a fixed cost/time/quality arrangement In a temporary enterprise (high intensity of human and materials resources, Unique aims, unique participants, unique tools).Who are the direct and indirect Involved participants of a construction project? Direct: •Client•Designer (Architect, Structural Engineer, Civil Engineer, Mechanical engineer, Electrical engineer) •Contractor (General Contractor, Subcontractors) Indirect: •Authorities (Public services) •Financing

PRINCIPLE

DESCRIPTION

LAYOUT

The interface should be a series of areas on the screen that are used consistently for different purposes

CONTENT AWARENESS

Users should always be aware of where they are in the system and what information is being displayed

AESHETICS

Interfaces should be functional inviting users through careful use of white space, colours and fonts. There is often a trade off between including enough white space to make the interface look pleasing without losing so much space that important information does not fit on the screen

USER EXPERIENCE

Although ease of use and ease of learning often lead to similar design decisions, there is sometimes a trade-off between the 2, novice users or infrequent users of software will prefer ease of learning,

What are the fire protection requirements of construction materials according to Council Directive 89/106/EEC? The Construction works must be designed and built in such a way that in the event Of an outbreak of fire: · the load-bearing capacity of the construction can be Assumed for a specific period of time; · the generation and spread of fire and Smoke within the works are limited; · the spread of fire to neighbouring Construction works is limited; ·occupants can leave the works or be rescued by Other means; ·the safety of rescue teams is taken into consideration. ·The Classification or availability of the structures should be considered based on The fire protection levels, and using data from reaction to fire tests.
