PL BIM LOD 2020

 

[1]

In 2020, the Ministry of Development and the Public Procurement Office BIM STANDARD PL [2] were published on the website of the Polish government administration, developed in cooperation with Skanska, BUDIMEX, WARBUD, PORR and experts of the EccBIM Foundation, under the patronage of PZPB, PZITB, SARP. One of the developed appendices to the standard is the LOgD / LOmI table (Graphics detail level / Information detail level). The table shows a very short detail system compared to other countries' studies. Project of rules for the preparation and implementation of cubature investments in Poland in accordance with the PN-EN ISO 19650 standard and the national construction law Document version No. 2.0 Warsaw, September 2020

Document translation

The document is divided into sections:

Land development: the area; roads, parking lots and green areas; utilities; small architecture;

Architecture: ceilings, frames, floors; walls; Windows and doors; cranes and escalators; curtain walls and skylights; Suspended Ceilings; handrails and balustrades;

Construction: foundations; reinforced concrete structures; metal constructions; prefabricated structures; wooden constructions; stairs, landings, platforms; roofs and canopies;

MEP: MEP devices; ventilation accessories; ventilation ducts; tubing; cable trays; completion of the ventilation system; pipe fittings;

Fit Out;

Temporary: development of the construction site; temporary installations; existing infrastructure; temporary soil improvement; cranes; formwork; demolition;

Each of the tables is based on the LOD 1 - LOD 5 ranges, which define the LogD / LomI requirements (graphics / information) and BIM D levels (3D Coordination (Application in 3D); 4D Work schedule (Application in 4D); 5D Bills of quantities and Cost estimates (Application in 5D); 6D Facility Management (Application in 6D)).

For graphics and information, a classification has been defined in the levels of detail: minimum, low, medium, high and maximum.

Occasional

Description for graphics (LOgD) Relates to key structural and architectural elements only. The modeled objects have: - a highly simplified outline (the object is modeled with a single straight solid or plane), - height in accordance with the story height, - assumed location on the projection based on assumptions typical for a given type of structure, - groups of typical elements (e.g. reinforced concrete columns, ceilings, windows, mechanical devices) may have the same theoretical dimensions. Multilayer elements (e.g. exterior walls) and those traditionally having complex geometry (e.g. steel profiles, doors, MEP fittings) are represented by single simplified geometric objects such as cuboids, cylinders and planes. It applies only to key structural and architectural elements. The modeled objects have: - a highly simplified outline (the object is modeled with a single straight solid or plane), - height in accordance with the story height, - assumed location on the projection based on assumptions typical for a given type of structure, - groups of typical elements (e.g. reinforced concrete columns, ceilings, windows, mechanical devices) may have the same theoretical dimensions. Multilayer elements (e.g. exterior walls) and those traditionally having complex geometry (e.g. steel profiles, doors, MEP fittings) are represented by single simplified geometric objects such as cuboids, cylinders and planes. Description for information (LOmI) The key structural, architectural and MEP elements have a name that describes the type and type of element (eg external multi-layer wall, reinforced concrete column, internal door, power generator).

Short

Description for graphics (LOgD) The modeled objects have: - a highly simplified outline (the object is modeled with a single straight solid or plane), - height in accordance with the height of the storey, - assumed location on the projection based on the basic assumptions prepared for the project, - groups of typical elements (e.g. all columns, ceilings or windows) should be divided into smaller sub-sets reflecting the assumed dimensions (e.g. reinforced concrete columns 500x500, windows with one, two or three sashes). Multilayer elements (e.g. exterior walls) and those traditionally having complex geometry (e.g. steel profiles, doors, MEP equipment) are represented by single objects or groups of several geometric objects such as cuboids, cylinders and planes. In low detail, the model solids are not modeled curvature (except for simple cylinders). Description for information (LOmI) All modeled objects have: - a name describing the type and type of element and a reference to the general specification (e.g. external multi-layer wall ZW03, reinforced concrete column KL02, internal door DW05, power generator GP01), - attribute specifying the basic type of material (e.g. reinforced concrete, wood, steel, aluminum ) for all objects for which it is required.

Average

Description for graphics (LOgD) The modeled objects have: - a simplified outline, the object is modeled using a group of straight solids and / or a plane (complex curves at the connections of solids are simplified, while the outer boundary of the object should accurately reflect its shape), - height in accordance with the height of the storey and taking into account the specificity of connections with other elements, - the assumed location on the plan based on detailed assumptions prepared for the project, - groups of typical elements (e.g. all columns, ceilings or windows) should be divided into smaller sub-sets reflecting the assumed dimensions (e.g. 500x500 reinforced concrete columns, single, double or three-leaf windows). Multilayer elements (e.g. exterior walls) and those traditionally having complex geometry (e.g. steel profiles, doors, MEP equipment) are represented by single objects or groups of several geometric objects such as cuboids, cylinders and planes. The average level of detail of the model bodies is understood to be the level in which only curves that can be mathematically described are used to reflect the curvatures. Elements should contain simplified geometry of key connections. Description for information (LOmI) All modeled objects have attributes as in the low level and additionally: - attributes that define the general material specification such as class, grade or strength (e.g. Concrete C25, Steel S355, EI90 fire resistance) for all objects for which it is required, - attributes specifying the type of finish, protection or insulation of an element, - attributes specifying the type, color and texture of the element's finish, - optional attribute specifying the manufacturer, - optional attribute specifying their location in the project (object, story, room).

Tall

Description for graphics (LOgD) The modeled objects have: - precise outline in all 3 dimensions, - height taking into account all restrictions resulting from the chosen construction method, - exact location on the projection based on the final assumptions prepared for the project, - in groups of typical elements, each element should fully reflect its geometry, taking into account its specific conditions. Multilayer elements (e.g. external walls) and those traditionally having complex geometry (e.g. steel profiles, doors, MEP equipment) are represented by single geometric objects or groups of such objects faithfully reflecting their real geometry. The high level of detail of the model bodies is understood to be the level at which higher order curves must be used to reflect the curvatures. The volume of the object model should not differ from the volume of the real object by more than 3%. Elements should contain the exact geometry of key connections and simplified geometry of details. Description for information (LOmI) All modeled objects have attributes as in the average level and additionally: - attributes specifying the manufacturer and catalog number (if available), - attribute specifying their location in the project (object, story, room), - attribute specifying the order assembly, if required and possible to define, - attributes specifying the method and frequency of servicing, durability and warranty information.

Maximum

Description for graphics (LOgD) The modeled objects have: - precise outline in all 3 dimensions, - height taking into account all restrictions resulting from the chosen construction method, - exact location on the projection based on the final assumptions prepared for the project, - in groups of typical elements, each element should fully reflect its geometry, taking into account its specific conditions. Multilayer elements (e.g. external walls) and those traditionally having complex geometry (e.g. steel profiles, doors, MEP equipment) are represented by single geometric objects or groups of such objects faithfully reflecting their real geometry. The high level of detail of the model bodies is understood to be the level at which higher order curves must be used to reflect the curvatures. The volume of the object model should not differ from the volume of the real object by more than 3%. Elements should contain the exact geometry of the key connections and the simplified geometry of the details, except that the model contains the detailed geometry of all connections and details. The structure and colors of the last finishing layer are accurately reflected in the model. Description for information (LOmI) All modeled objects have high level attributes and additionally: - attributes containing a set of as-built information (such as: date of execution / assembly, company performing the work, date of acceptance, name of the supervising and commissioning engineer, remarks about the fault reported during collection),
