GLOSSARY FOR ACROBATIC AND ROPE ACCESS WORKS

 

A

 

Acrobatic works / rope access works / aerial works : Acrobatic or rope access works refer to all types of works, whether at height or subaquatic, which are performed by rope access technicians or building professionals from the public works, civil engineering or industry sector. Examples of rope access works: securing cliffs, works on rock falls protection, reinforcement of retaining walls or rock walls, reshaping and cable laying.


“The term ‘acrobatic works’ gathers operations ‘on buildings whether by nature or destination’, using climbing and progression techniques developed in alpinism and speleology, when scaffolding and cradles would be too costly or impossible.” From ‘Travaux acrobatique, calcul des forces de choc sur les cordes d’assurage’ de l’INRS (les notes scientifiques et techniques de l’INRS), December 1995

Carcass work : The carcass work on a structure involves the construction of its structure, generally with reinforced concrete or metal, but also with wood, stone, brick and sometimes laterite mud. The carcass work starts with the delivery of the deep foundations and earthworks. The frame of the structures is generally divided into vertical and horizontal elements (the first elements are the walls, poles for the buildings and piers for bridges / the latter are the mats, beams, floors, landings, balconies for buildings and decks for bridges). Cranes are used to supply zones of the site with construction materials, and to shift tools and machinery. In order to meet cost effective requirements, a construction site must optimize its work planning, tools and personnel costs.

 

Civil Engineering : Civil engineering refers to the body of civil construction techniques. Applied to industrial rope access, civil engineering deals more specifically with rehabilitation, maintenance and securing operations on construction structures in order to ensure public safety and environment protection. Civil engineering applies to a wide range of works, and mainly includes areas such as structures, geotechnics, hydraulics, transport and environment.

 

Cliff stabilization : Type of acrobatic works performed when natural risks of rock falls occur. Protection technique for cliffs by nailing, wire netting, tecco and installation of rockfall catch barriers.

 

Construction climber: the mountain climber is an athlete who practices high altitude climbing using various progression techniques. In acrobatic and rope access works, we often call them construction climbers because they use those same climbing techniques. The rope access worker must master the progression techniques and the equipment when evolving in the vertical world. He must also know the lifting and charge transfer techniques, be able to evacuate an injured person...

 

Construction and Public Works : The economic sector for construction and public works includes all the conception and construction activities on public and private buildings, whether industrial or not, and on infrastructures such as roads and pipelines. The sector for Construction and Public Works is one of the top industries in France. Applied to acrobatic and rope access works, the construction and public works more specifically refer to rehabilitation, maintenance and securing operations of public and private structures, often on roads that require development work and rock fall protection for example.

 

Control authority : The control authority or client is the instructing party (government, community, business…) for whom the acrobatic and aerial rope access works are performed. This concept, like the contracting authority, finds its origins in the construction sector. The control authority assistant is an individual or legal entity who has received the authority to legally and financially represent the client.

Engineer specialized in contaminated soil and sites : An engineer specialized in contaminated soil and sites is an expert in the study of soil, water and air, and his primary job is to evaluate health and environmental risks. His expertise helps to draw a conceptual diagram which synthetizes the situation of a rope access works site for example, taking into account the sources, vectors and pollution targets. His expertise is most often based on the processing of the existing historical ground data obtained from surveys, drilling, sampling and analysis of soil, water and air. As the health risks related to pollution are increasingly being taken into account, the role of the engineer specialized in contaminated soil and sites has become of utmost importance in construction public works.

 

Engineering structure : An engineering structure refers to a public works construction linked either to communication circuits (bridges, viaducts, tunnels, navigation locks…) or to the protection against earth and/or water action (retaining walls, gabions, piers…) or to water impoundment (dams, dikes…)

G

 

Geotechnical engineer : The geotechnical engineer is responsible for investigating the soil from a mechanical viewpoint. He offers his expertise to the contracting authority, in the choice of foundations. His intervention can greatly influence the structure’s design. His work is based on the evaluation of the soil investigations (surveys, drillings, soil identification testings...)

L

 

Light work : Light work is that which is not considered as carcass work, nor works on foundations, framed structures, or roofs and that relies on the structure.

M

 

Masonry : Masonry is an art of construction through the assembling of elementary materials, bound together in a non reversible way. The mason’s expertise is based on cladding works (plaster, tile laying…) which contribute to hold the whole structure against external events (moisture, frost, etc). Acrylic stucco which replaces traditional stucco made from lime reflects more and more this combination.

 

Metalworking : metallic framework, cladding and roofing, building hardware. Today, metallic construction refers to small building hardware to large floor bridges or building frameworks, but also to industrial or farming depots, commercial buildings, offices… There are numerous occupations related to metalworking: consulting technicians or engineers (who work on industrial designs, estimations of the materials and structures strength, nomenclatures…), production plants and site assembling trades.

Natural hazards (prevention) : A natural hazard refers to the risk of exposure to natural disasters or to construction hazards in relation to unanticipated natural unknowns. The natural risk generally takes into account both a natural phenomenon, like a flood, a fire, a storm, a mudslide, an earthquake…, and human vulnerability resulting from inhabited or man-used locations which are likely to be altered or destroyed in the event of a natural hazard.

Prevention of natural hazards : A natural hazard refers to the risk of exposure to natural disasters or to construction hazards in relation to unanticipated natural unknowns. The natural risk generally takes into account both a natural phenomenon, like a flood, a fire, a storm, a mudslide, an earthquake…, and human vulnerability resulting from inhabited or man-used locations which are likely to be altered or destroyed in the event of a natural hazard.

 

Public works (and construction): The economic sector for construction and public works includes all the conception and construction activities on public and private buildings, whether industrial or not, and on infrastructures such as roads and pipelines. The sector for Construction and Public Works is one of the top industries in France. Applied to acrobatic and rope access works, the construction and public works more specifically refer to rehabilitation, maintenance and securing operations of public and private structures, often on roads that require development work and rock fall protection for example.

R

 

Rope access worker : The rope access worker is a multi-task technician who has received extensive training in building, aerial works and securing of height interventions. The rope access worker is also called a construction climber or acrobat. Rope access works fit well in the industry and public works sector, as well as in the entertainment realm. The rope access worker intervenes for example on sites such as : window-cleaning, facade scaling and masonry, sheet metal work, installation of anti-bird protection systems, silo cleaning, framed structures, installation of commercial banners, and hanging of sound and light systems.

S

 

Shotcrete : Shotcrete is concrete which is propelled after being mixed dry or wet on a base, by spraying on successive layers. It allows for very complex shapes such as domes or shells, for example. It is often used in rope access works and/or underground works.

 

Surveys : A geotechnical survey is an investigation of the subsoil, performed with or without drilling, which is designed to determine the nature and mechanical, physical and possibly chemical features of its components in order to anticipate its behavior during the construction operation.

T

 

Technical supervision of the construction : The technical supervision of the construction helps to prevent the technical unanticipated hazards which are likely to cause accidents during acrobatic and rope access works or during all types of constructions works, and to verify compliance to the construction regulations.

 

 

W

 

Works foreman : The works foreman is the head of the construction site. The works foreman is generally assisted by worksite managers and by specialized consultants such as coordinators or engineers for example.
