7 Byggepladsen og udførelsen af Byggearbejder – Guidance on Construction Sites and Building Work
The Bygningsreglementets vejledning om byggepladsen og udførelsen af byggearbejder is an official guidance document issued by the Danish Trafik-, Bygge- og Boligstyrelsen. It details the regulatory requirements and recommendations for planning and executing construction activities in Denmark under the framework of the Bygningsreglementet 2018 (BR18), specifically addressing Chapter 7, § 161 through § 165. This document serves as a reference for ensuring that construction sites are managed to prevent damage to persons or property and to minimize nuisances to the surrounding environment.
The scope of this guidance encompasses all types of construction projects, from minor renovations to large-scale developments. It integrates several related legal frameworks, including the Arbejdsmiljølovgivningen (Working Environment Act), Vinterbekendtgørelsen (Winter Regulation), and environmental protection statutes. Key regulatory domains covered include site organization, fire safety measures, moisture protection for sensitive materials, noise and vibration mitigation, and waste management. It explicitly references technical standards such as DS/EN 3 for fire extinguishers and various executive orders (bekendtgørelser) regarding client and advisor duties.
The following sections outline the specific requirements for site layout, safety protocols, and environmental considerations necessary to maintain compliance with Danish building codes during the construction phase.
General Planning and Site Safety (§ 161 - § 162)
In accordance with § 161 and § 162, construction work must be planned and executed to ensure no damage occurs to persons or buildings on or around the site. This includes preventing the collapse of new or existing structures during excavation, construction, or renovation.
- Structural Stability: New and existing constructions must maintain sufficient stability throughout the building process, especially during energy renovations.
- Installation Safety: Building components must be dimensioned for safe mounting, following the supplier's installation instructions.
- Site Security: Necessary measures such as bracing, fencing, or safety nets must be established depending on the nature of the work.
Fire Safety and Prevention (§ 163)
Fire protection measures must be implemented to ensure that fire safety in existing occupied buildings is not compromised and that the risk of fire spreading is minimized.
- Access Routes: The site must remain accessible for emergency vehicles at all times, with no blockages from scaffolding or material storage.
- Material Storage: Flammable building materials should be stored at least 5 meters away from buildings to prevent fire transfer.
- Temporary Structures: Construction sheds (skurvogne) and storage containers must maintain safe distances to boundaries and other buildings according to Chapter 5 of BR18.
- Fire Protection Plan: For specific sites, a fire safety plan should include organization, alarm systems, and evacuation instructions.
Hot Work and Extinguishing Equipment
Varmt arbejde (Hot work), including welding, grinding, and the use of open flames, poses a significant fire risk and should ideally take place away from buildings.
- Extinguisher Classes: Sites must be equipped with appropriate fire extinguishers based on the risk: Class A (solids), Class B (liquids), Class C (gases), and Class D (metals).
- Electrical Safety: Water-based extinguishers may be used on electrical fires up to 1000V at a 1-meter distance, provided they meet DS/EN 3 standards.
- Supervision: Hot work areas must be monitored, and fire watches may be required in high-risk scenarios.
Nuisance Mitigation and Environment (§ 164)
Construction activities must not cause unacceptable nuisances to neighbors or the public. The municipality may intervene by setting specific noise limits or operating hours.
- Noise and Vibration: Mitigation should occur at the source by choosing low-noise machinery or using acoustic screening and containers.
- Dust Control: Regular watering, vacuuming, or covering of work areas is required to prevent dust dispersion.
- Waste Management: Waste and packaging must be removed immediately from buildings and stored in designated containers outside.
- Public Areas: Access roads and sidewalks must be kept clean and free of debris.
Climatic Conditions and Moisture Protection (§ 165)
Provisions must be made to protect moisture-sensitive materials from rain, snow, and cold during the construction process to prevent mold growth.
- Moisture Management: Strategies include total covering of the construction area or the use of climate-controlled storage.
- Winter Measures: Projects occurring between November 1st and March 31st must comply with the Vinterbekendtgørelsen.
- Quality Assurance: Procedures should ensure that wet materials or components with mold are not incorporated into the final building.
Frequently Asked Questions
What is the minimum safety distance for storing flammable materials near buildings?
Flammable building materials should be stored at least 5 meters away from all buildings to prevent the spread of fire.
Which regulation governs construction work during winter months in Denmark?
Construction work between November 1st and March 31st is governed by the Vinterbekendtgørelsen (Bekendtgørelse nr. 477).
What are the requirements for 'Hot Work' (Varmt arbejde)?
Hot work, such as welding or using angle grinders, must be planned in advance, ideally performed away from buildings, and requires the presence of appropriate fire extinguishing equipment.
How should noise from a construction site be managed?
Noise should be reduced at the source by using quiet machinery; additional measures include establishing noise screens and informing neighbors about the timing of noisy activities.
What fire extinguisher type is required for electrical installations on a site?
Powder extinguishers, CO2 extinguishers, or approved water extinguishers (up to 1000V at 1m distance) are suitable for electrical fires depending on the specific equipment and DS/EN 3 classification.
Who is responsible for coordinating safety among different employers on a site?
The client (bygherren) has the duty to coordinate and plan the work of various employers as per Bekendtgørelse nr. 117.
How can mold growth be prevented during the construction phase?
By protecting moisture-sensitive materials from the elements, using total covering when economically feasible, and ensuring adequate drying time before materials are enclosed.
What are the requirements for construction site fencing?
Fencing must clearly delineate the site, prevent unauthorized access, and should not block emergency access routes or visibility for traffic.
