Bricklayers face significant physical strain from energetic load, back stress, repetitive upper extremity movements, and awkward postures, while supervisors contend with prolonged walking, standing, and psychosocial pressures like workload and time constraints. This human factors research insight is drawn from a 2010 study published in American Journal of Industrial Medicine. Using Systematic review, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers must consider the specific physical and psychosocial loads of construction roles to create safer, healthier, and more sustainable work environments.

Key Findings
- 01Bricklayers experience high energetic load, significant lower back strain, repetitive upper extremity exertions, trunk flexion exceeding 60°, and elevated arm work.
- 02Bricklayers are exposed to dust and quartz exceeding limit values, as well as vibration and noise above acceptable levels.
- 03Bricklayers have an increased risk of lung cancer, low back pain, arm and leg complaints, and injuries.
- 04Construction supervisors commonly engage in physically demanding activities such as walking and standing.
- 05Supervisors face psychosocial demands including high mental workload, time pressure, long working hours, and social-organizational factors.
Application
Design takeaway
Designers must consider the specific physical and psychosocial loads of construction roles to create safer, healthier, and more sustainable work environments.
How to apply
When designing tools, equipment, or work processes for construction, explicitly map the physical and psychosocial demands identified in this review to inform design decisions and risk assessments.
Project actions
- 01When researching a product for construction, consider how it might impact the physical or mental strain on the user.
- 02Look for existing standards or guidelines related to ergonomic limits for specific movements or exposures.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Comprehensive search of multiple databases.
- +Systematic approach to synthesize existing evidence.
Limitations
The original study's data is from before 2009, so newer technologies or safety measures might not be reflected.
Reliability & validity
The reliability of the findings depends on the quality and consistency of the studies included in the systematic review. Validity is enhanced by the systematic methodology, but may be limited by publication bias or the heterogeneity of the original studies.
Think critically
How might advancements in robotics or automation in construction potentially alter these identified occupational demands and health risks for future generations of workers?
Design Principles
"Design for specific occupational demands to mitigate health risks and enhance worker well-being."
Understanding these specific occupational demands is crucial for designing safer work environments and targeted health surveillance programs. By quantifying these stressors, designers and safety professionals can develop interventions that mitigate risks and prevent long-term health issues.
What This Means for Your Design
This study looked at what makes bricklayers and construction supervisors unhealthy at work. Bricklayers have to lift heavy things, bend a lot, and use their arms in awkward ways, which hurts their backs and arms. They also breathe in dust and are exposed to loud noises. Supervisors have to walk and stand a lot, and often feel stressed by their workload and deadlines. Both groups have a higher chance of getting lung cancer and getting hurt on the job.
How to use in your project
- 1.Use this research to justify the need for specific ergonomic features in your design, or to identify potential health risks your product might mitigate.

Paragraph starter
This research highlights significant physical demands on bricklayers, including energetic load exceeding 25% heart rate reserve and lower back strain beyond NIOSH thresholds, alongside repetitive upper extremity exertions and awkward postures. Construction supervisors, conversely, face considerable psychosocial demands such as high workload and time pressure, alongside prolonged standing and walking. Both occupations exhibit increased risks for lung cancer and injuries. These findings underscore the necessity of designing products and systems that actively mitigate these specific occupational stressors to promote worker health and safety.
