Construction and building systems study guide (Architecture)
This unit is about how a building is actually put together and made to work. It covers the main construction systems and the newer technologies that compete with them, the drawings and documents a contractor builds from, the materials of walls, roofs and finishes and the physics that decides whether an envelope keeps heat out without trapping water, the services an architect must make room for (air conditioning, water, power, fire protection, lifts and building controls), the acoustics and lighting of rooms, and the structural systems that carry the loads. Where the architect is expected to calculate (U-value, condensation, air flow, reverberation time, luminaire numbers, lift capacity, tributary loads, arch thrust) the guide teaches the calculation; every property, coefficient and rule of thumb an example uses is given in its statement.
Structured by the official ETEC subject standard for this topic: every listed topic and learning outcome, with formulas, figures and worked examples. The full sections are available to members in the app.
SKU 3.1 · Construction systems
Construction systems and technologies
The families of construction a design can be built in (load-bearing walls, frames, panels and hybrids) and the technologies that are changing how they are built: precast and modular construction, light-gauge steel, engineered timber, post-tensioning and three-dimensional printing.
Construction drawings and documentation
What a contractor builds from: the drawing set and its scales, details and schedules, the specification and how it is organised, levels and falls, and how drawings are revised, checked against shop drawings and closed out as as-built records.
SKU 3.2 · Building materials
Building materials: properties, tradition and selection
The standard materials of structure, envelope, finishes and insulation, the traditional materials of the Kingdom's regions and why they worked, and how to select materials against performance, cost and sustainability with a pass/fail screen and a weighted score.
Material science of the envelope: U-value and condensation
How layers of material resist heat in series, how to compute the U-value of a wall or roof, how the temperature falls through it and where moisture can condense, and the newer materials (aerogels, vacuum panels, phase-change materials, low-emissivity glass, cool roofs) that change those numbers.
SKU 3.3 · Building systems
Mechanical, plumbing, electrical and fire systems
What the services of a building do and how much space they need: air conditioning and ventilation (air changes, duct sizes, cooling loads and why chilled water travels in pipes), water supply and drainage, electrical distribution, and the fire detection, suppression and compartmentation an architect plans for.
Acoustics: reverberation, insulation and noise
How a room's volume and surfaces set its reverberation time (Sabine), how to add absorption to reach a target, how sound levels add in decibels, how walls block sound by mass and airtightness, and what limits apply to noise for comfort and safety.
Illumination: lumen method, daylight and quality of light
How many luminaires a room needs for a target illuminance (lumen method and room index), how they are spaced, how lighting power density is checked, and the qualities beyond quantity: glare, colour, daylight, sensitivity to light and controls.
Vertical transport and smart building systems
Lifts and escalators as the circulation system of tall buildings, sized by handling capacity and interval, and the computer-based systems that now run buildings: building management systems, IoT sensors, smart metering, security networks and digital twins.
SKU 3.4 · Structural systems
Structural principles: loads, load paths and tributary areas
The loads a building carries, the path they take from slab to soil, how to estimate the load on a beam or column from its tributary area and a factored load combination, and the configurations that make a structure strong or weak.
Types of structural systems and their integration
Structural systems grouped by how they carry load (bending, axial, form and surface action, lateral systems for height), preliminary sizing by span-to-depth rules and arch thrust, and how structure is integrated with services, floor heights, grids and architectural expression, including newer systems.
