Skills for Formworking
This subtopic covers the foundational practical skills required for formworking, including setting out, assembling, and striking formwork for concrete structures. Learners will develop competence in preparing resources, using tools and materials safely, and cleaning the work area in accordance with industry standards and health and safety regulations.

Topic Overview
Formwork is essentially a temporary mould or casing into which fresh concrete is poured and compacted. It's a critical, often temporary, structure used to support concrete until it gains sufficient strength to support itself. For the NOCN Level 1 Award, you'll learn about the fundamental principles, different types of formwork, and the essential safety procedures involved in its construction, use, and dismantling. This qualification provides foundational knowledge for anyone looking to work with concrete structures, ensuring they understand how to create precise shapes and achieve desired finishes safely and efficiently.
Understanding formwork is non-negotiable in construction, as it directly impacts the structural integrity, appearance, and cost-effectiveness of concrete elements like walls, columns, beams, and slabs. Without correctly designed and erected formwork, concrete structures would lack the necessary shape and strength, leading to potential failures and significant safety hazards. This module fits into the wider construction curriculum by providing a practical application of material science (concrete curing) and structural support principles, bridging the gap between theoretical knowledge and hands-on site work. It's a stepping stone to more advanced concrete technology and structural construction techniques.
Key Concepts
Core ideas you must understand for this topic
- →**Purpose of Formwork:** To provide a temporary mould for fresh concrete, holding it in the desired shape until it cures and gains sufficient strength.
- →**Types of Formwork Materials:** Understanding common materials such as timber (plywood, softwood), steel, aluminium, and proprietary plastic systems, recognising their suitability for different applications.
- →**Formwork Components:** Identifying and describing key parts like sheeting, walers, soldiers, props/shores, ties, and bracing, and their function in maintaining stability and shape.
- →**Safety Procedures:** Adhering to strict health and safety regulations, including safe erection and dismantling practices, working at height, manual handling, and using personal protective equipment (PPE).
- →**Striking Formwork:** Knowing when and how to safely remove formwork without damaging the concrete or endangering personnel, considering concrete strength and curing times.
Learning Objectives
What you need to know and understand
- 1. Be able to prepare to carry out formworking.2. Be able to prepare resources to carry out formworking. 3. Be able to carry out formworking. 4. Be able to clear and clean the work area after tasks.
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating a systematic approach to planning work, including interpreting simple drawings or instructions and identifying potential site hazards before starting.
- Expect evidence of selecting and checking all necessary hand tools, power tools, formwork components (e.g., panels, soldiers, wedges), and fixings, ensuring they are fit for purpose.
- Assessors should look for accurate assembly of formwork to specified dimensions, ensuring it is plumb, level, and adequately braced to resist concrete pressure, with all joints tight to prevent grout loss.
- Credit safe and efficient striking and dismantling of formwork without damage to concrete or components, followed by thorough cleaning of tools, equipment, and work area, with waste disposed of according to environmental guidelines.
Assessment Guidance
Guidance for achieving higher grades
- 💡Provide photographic or video evidence of key steps: pre-use equipment checks, the formwork fully assembled with a level or plumb bob in place, and the cleared work area afterwards.
- 💡In your written account, justify each decision—e.g., why you selected a particular bracing method or release agent, and how you ensured the formwork could withstand the concrete load.
- 💡Always reference health and safety legislation and manufacturer’s instructions when explaining how you prepared for and carried out formworking tasks.
- 💡Demonstrate awareness of sustainability by detailing how you minimised waste, segregated materials for recycling, and cleaned tools responsibly.
- 💡**Prioritise Safety Knowledge:** Examiners will heavily assess your understanding of health and safety regulations specific to formwork. Be prepared to describe safe working practices, identify hazards, and list appropriate PPE. This demonstrates a responsible approach crucial for site work.
- 💡**Master Terminology and Components:** Learn the correct names for all common formwork components (e.g., walers, props, ties, sheeting) and be able to explain their function clearly. Often, questions involve labelling diagrams or describing the purpose of specific parts.
- 💡**Understand the Sequence of Operations:** Formwork construction and striking follow a logical sequence. Be able to describe the steps involved from preparation and erection to pouring, curing, and safe dismantling. This shows a practical grasp of the entire process.
Common Mistakes
Common errors to avoid in your coursework
- Failing to wear the correct personal protective equipment (PPE), such as missing gloves when handling release agents or overlooking eye protection during sawing.
- Using warped or damaged formwork panels and defective clamping devices, which leads to misalignment and concrete leakage.
- Not checking the formwork for plumb and level before pouring, resulting in out-of-tolerance concrete elements that may require costly remedial work.
- Leaving tools and materials scattered after striking formwork, creating trip hazards and contravening site housekeeping rules.
- **Misconception:** Formwork is just a temporary barrier to hold wet concrete; its strength isn't as important as the final concrete structure. **Correction:** Formwork must be incredibly strong and rigid to withstand the immense hydrostatic pressure of wet concrete, as well as construction loads. Failure to ensure its structural integrity can lead to catastrophic collapses, significant delays, and severe safety risks.
- **Misconception:** Any timber can be used for formwork, as long as it looks sturdy. **Correction:** Specific grades of timber or engineered wood products like plywood are required for formwork. These materials must be strong, durable, dimensionally stable, and often treated to prevent adhesion to concrete and ensure a smooth finish. Using unsuitable materials can result in poor concrete finish, structural failure, or excessive material waste.
- **Misconception:** Formwork can be removed as soon as the concrete looks hard on the surface. **Correction:** Concrete needs to achieve a specified percentage of its design strength before formwork can be safely removed, a process known as 'striking'. This strength gain depends on factors like concrete mix, temperature, and humidity. Premature striking can lead to cracking, deformation, or even collapse of the partially cured concrete element.
Revision Plan
How to revise this topic in 1–2 weeks
- 1**Week 1: Fundamentals & Safety:** Begin by thoroughly reviewing the purpose and importance of formwork. Dedicate time to understanding all relevant health and safety regulations, including risk assessments and PPE. Study the different types of formwork materials (timber, steel, proprietary) and their applications.
- 2**Week 1: Components & Assembly:** Learn to identify and describe the function of each major formwork component (sheeting, walers, props, ties, bracing). Practice drawing simple formwork systems and labelling their parts. Watch instructional videos demonstrating basic formwork assembly.
- 3**Week 2: Pouring, Curing & Striking:** Focus on the process of concrete pouring within formwork, ensuring proper compaction. Understand the critical factors influencing concrete curing and the criteria for safely striking formwork, including typical minimum times for different elements.
- 4**Week 2: Quality & Maintenance:** Review how to ensure a good concrete finish and common defects that can arise from poor formwork. Understand basic maintenance and storage of formwork materials.
- 5**Revision & Practice:** Consolidate your knowledge by creating flashcards for key terms and components. Practice answering short-answer questions and diagram labelling exercises. If possible, observe formwork being used on a construction site or in a workshop to link theory to practice.
