Complex automation of designing
Designing automation – the new progressive developing process conducting to considerable change of existing technology in architecturally-building designing. The existing sequence and time of performance of separate operations in designing change, the form of representation of the information, efficiency at the automated designing considerably depends on the organisation of interaction of the person with the computer, systems of representation of a reference material. At use of separate programs the technology of traditional system of designing considerably does not vary, however there are new operations, for example, preparation of the initial data for machining, and is reduced time of performance of separate stages.

Complex automation of designing brings basic changes in technology of designing, beginning from preparation of the initial data, representation of reference materials, decision and estimation methods and before final operations, i.e. Before manufacturing and reproduction of the design-budget documentation.

Now the considerable number of project institutes of the Russian Federation already has experience of use of programs for automation of separate stages in the course of designing. Experience of complex automation of designing while is improved and consequently stable methods and procedures of such designing still definitively are not fulfilled. However a transitive link between application of private programs and complex automation of process of designing are technological lines of the automated designing (TLD) which are developed in a number of scientific research institutes of our country and abroad. TLD unite a little in common working groups (brigades) of the automated designing. Primary goal of TLD is improvement of quality of the design-budget documentation and labour productivity of designers.

By working out of projects TLD can carry out a certain complex of design works. Thus structure of TLD has two subsystems: projecting and providing. Projecting subsystems directly participate in processes of working out of the project, and providing – are engaged in technological preparation of processes of the automated designing.

The organisation, management and planning of process of designing in TLD carry out by means of the developed technological cards which have following three kinds: technological cards of designing (TCD), executive technological cards (ETC) and organizational technological cards (Quality Department). Basic of them at drawing up of line technology of designing on TLD is TCD which is made in the course of the analysis of all operations which are carried out on a technological line, with definition of terms of designing and expenditures of labour at each stage.

Basis of the organisation of process of designing is Quality Department which intend for representation of data on presence of the software and the list of the design operations making considered design process.

TLD uses a complex of the means including the computing system, the organizational technics, a communication facility.

The technological line on designing of bearing skeletons of civil buildings on the basis of AI-04-COURT series (a skeleton orthogonal) was one of the first in our country.

This technological line of designing COURT has provided release of working drawings, assembly diagrammes of the bases, overlappings, formwork and reinforcement drawings of individual elements, and also specifications, pay sheets and the budget documentation, i.e. A full set of the design documentation of a skeleton. The designer in the course of use TLD KORT only makes decisions and analyzes results, and processing of the accepted decisions, information storage (constant and received in the course of designing) carries out the computer.

The software is united in seven special blocks, each of which carries out certain functions. In block KORT-1 the information on the idealised scheme of a projected building (construction) is formed, in block KORT-2 durability and stability of a building is checked, in block KORT-3 configuration of a construction from modular elements dares, in block KORT-4 non-standard elements are projected, block KORT-5 provides reception of drawings on an output equipment of the graphic information, block KORT-6 produces the budget documentation, and block KORT-7 represents an information retrieval system of a technological line of the automated designing. The software structure allows to make to it changes and additions while in service lines.

Designed and experimentally implemented a different production line computer-aided design of large-panel residential buildings – LPB. This line is intended for the design of large-panel houses a cellular structure with a common step of cross bearing walls at the stage of technical design. With this production line background information for the design can be divided into fixed and variable. By continuing include: standards, directories, architectural and construction of parts and industrial products, the catalog of standard elements of house, etc., to variable information – characteristics that define the structure of design objects (spans, number of floors, number and types of flats, etc.). As a result of the line LPB can choose the best architectural planning and design solution and provide the necessary project documentation – drawings, specifications and estimates. Method of designing a LPB is based on extensive use of standard solutions. Design runs on six levels: 1-industrial products and parts (type, general serial) 2 – construction-planning cell (space group, the limited load-bearing structures), 3 – apartments and staircases, elevator components, 4 – floor sections (groups of apartments and staircase-lift assemblies); 5 – block-section (a set of floor-sections, united by one unit vertical ties), 6 – house (a set of block sections).

Project working out is conducted consistently from small elements to larger, i.e. The technology of designing at each level consists of configuration of elements of the given level from elements of underlaying level. At each level the indicators characterising elements of given level are defined. Thus the pas all levels of designing occurs an estimation of variants of design decisions.

Algorithms are developed for a choice only those variants which meet the requirements in advance set, for example to the standard. By means of the software-realised algorithms the indicators characterising the different parties of the design decision are defined. A complex estimation of design decisions it is possible to carry out in TLD LPB two ways: the designer who can consider additional indicators; algorithmically, by specially developed technique. Technological process provides consecutive work, conditions where the formulation of the initial data is made for designing, including the preliminary analysis and a choice of key parametres of designing; the second block of automation of search architecturally-planirovochnogo decisions with working off of plans, facades and perspective images;

The third block of the general designing of object and its calculation with delivery of assembly drawings and specifications;

The fourth block of working out of the engineering equipment with delivery of the design documentation on these decisions;

The fifth block of definition of budget cost under individual quotations and the integrated budget norms with estimate delivery.

Designing in TLD LPB is conducted in a mode of dialogue of the designer and the computer that provides operative input of commands by means of the teletype, keyboards of a control panel or a light pencil and an operative conclusion of the information to the printer or the screen of an electron beam tube (display). Working out of drawings is based on a principle of assemblage of breadboard models of drawings from separate fragments and details on special breadboard models.

In a search stage the big place occupies interaction with customers of projects, systems more a high rank, adjacent projecting subsystems of TLD. At this stage problems also are solved: gathering of the reference and standard information; formation of results of preliminary study of the project in graphic and tabular kinds (the first intermediate results); formation of variants of layout and constructive decisions, their estimation and a choice of optimum design decisions; formation of tasks of adjacent subsystems of TLD. Solved problems at this stage demand the big participation of architects in the course of designing. Means at a search stage use basically for information processing under decisions which are accepted by the architect.

In a detailed stage following primary goals dare: gathering of loadings; a choice of bearing and protecting designs; designing of knots and elements; manufacturing and release of the design documentation, and preparation of the task for working out of the adjacent documentation. On a detailed stage there is a possibility of the program decision of all listed above problems. However this stage cannot automatically be made, without participation of the person behind which there are functions of the control, updatings and estimations of received results.

Necessary condition of complex interaction of all subsystems is presence of uniform digital model of an industrial building which allows to provide system unity of all information communications of projecting subsystems. Each block contains certain structure of the data in model:
- the block “The building situation” – the information on building area, restrictions on available resources, technological and social and economic requirements to object of designing;
- the block “Object structure” – structure of elements of object and their interrelation;
- the block “Object typology” – classification of types of objects of industrial buildings to destination, floor, to operating conditions etc.;
- the block “Object topology” – possible configurations of buildings, their parts and separate elements;
- the block “The object metrics” – value of parametres of industrial buildings: flight, a step, height, the sizes of temperature blocks etc.;
- the block “Quality of object” – the technical and economic indicators characterising a project cost and its specific indicators, expenses of work, materials, conveniences of a lay-out and. Other
