ABSTRACT
Introduction. The development analysis of domestic residential building construction of volumetric blocks, starting from the 60s of the twentieth century to the present time, is given. It is noted the innovative nature of the transition from low-volume blocks to large-sized blocks of high and full factory readiness. The problems that have arisen in this case are indicated, of which one of the most acute is the determination of organizational and technological parameters for the construction of residential buildings.
Materials and methods. The role of organizational and technological parameters of the objects' construction is described — the duration of construction and its stages, the complexity of work, the number of workers. The content of the timing carried out by the MonArch Group of Companies for the installation of large-sized volumetric blocks of a four-story residential building in Yakovlevo-2 village (New Moscow) is revealed. The main installation operations are analyzed with an indication ^ n of the time spent on each floor and the roof arrangement. s ®
Results. Based on the final results of the timekeeping materials generalization, three estimates of the duration of a building n h construction of large-sized blocks are proposed — pessimistic, satisfactory, optimistic. The found dependences "duration ^ | of building construction — the number of large-sized blocks installed taking into account the roof arrangement" are revealed _ * with the corresponding calculation formulas. The formula for calculating the labor intensity of installers work and crane ^ S maintenance workers is also given. 5) C
Conclusions. The prospects for the innovative technology development for the construction of residential buildings of large- * y sized blocks are substantiated, provided that capital investments are allocated and the efforts of research and design organi- ^ I zations are combined to comprehensively solve the problems that have arisen. To solve the problematic tasks of determining o S the indicators of organizational and technological parameters of buildings construction of large-sized blocks, an approach l z and methods for assessing the duration of construction and the complexity of installation work on the assembly of buildings J 9 are proposed. o 7

INTRODUCTION

The beginning of residential buildings construc-x o tion of the fifth industrial generation is characterized by > j« the emergence of innovative technology of their con-2 ~ veyor assembly on construction sites from large-sized . t- volumetric blocks of full factory readiness. The transfer t- of main volumes of work from construction produc-| 3 tion to industrial production will qualitatively change •7 £ the entire system of reproduction of the housing stock, i including the design, construction and operation of resits -g dential buildings [1].
S. .-2 The residential buildings erection from volumetric
o y blocks began in the second half of the 60s of the twen-
co <£ 0
J? 13 tieth century. By number of research and design organi-
° zations — the Central Research Laboratory (TSNIL-3)
z .2 of Glavstroy (Moscow), the Research Institute of Con-
$ E struction and Architecture (Minsk), Gidroproekt (Mos-—
c £= cow), Dalmorproekt (Artem), etc. in the period 1956-
iz O
£ o 1958, a number of new projects were developed for
¡n ° the construction of residential buildings from volumetCO —
g [z ric blocks. Most of these projects provided for the use of
fj o volumetric blocks in the form of a block room, a block
? >, for two rooms, block apartments and block sections.
For example, a block-room was a reinforced concrete
— 2 box with dimensions from 2.4 x 4.8 m to 3.6 x 6.0 m
>» 3 and a weight of 6-10 tons, and a block for two rooms
l_ w had a length of 6-10 m and a width of 6 m with a weight
® EE of 20-30 tons. Structural schemes of residential build-
| s£ ings made of volumetric blocks provided for three op-
¡3 +5 tions — panel-block, frame-block and block. In 1959,
u ¡¡^ the first experimental building was built in Lublino, Moscow region, in which block rooms were assembled
from leca flat panels in a special conductor with their fixing by welding together.
Widespread construction of residential buildings of volumetric blocks began in 1961 in Krasnodar, Minsk, etc. In Krasnodar, residential 5-storey buildings were erected according to the GPI-5 project (Moscow) from block rooms consisting of monolithically connected three walls and a bottom in the form of ribbed slabs 10 cm thick for the walls and 12 cm for the bottom. The block rooms of the Minsk variant differed in that they consisted of four walls, but without a bottom. Since 1963, according to the project by Permproject, 5-storey buildings made of leca block boxes have been built in Perm. All blocks were divided into three types — residential, sanitary-kitchen and staircase with the same size of 3.2 x 5.2 x 2.7 m [2].
It should be noted that all the volumetric blocks used had a high factory readiness. In particular, glazed windows, doors and wall cabinets were installed in them, engineering networks with full wiring, plumbing and electrical appliances were installed. The finished blocks were installed by cranes equipped with balancing traverses on trailer platforms. The blocks were installed, as a rule, from wheels. The timing carried out at that time allowed one to establish that the costs of manufacturing and completing the blocks came to about 75-85 %, reducing the consumption of concrete by 25-28 %, reducing the duration of construction by 3-4 times. The installation time of one unit in the design position was 20-30 minutes. During one shift, from 7 to 10 blocks were installed, and in 10-12 working days, with three shifts, a five-story residential building for 60 apartments was erected [3-8].
Modeling the residential buildings erection of large-sized blocks
C. 463-470
Modern technology of residential buildings erection of volumetric blocks is characterized by the transition to large-sized blocks of full factory readiness [9-15]. Conducted at the present time by the MonArch Group of Companies (Moscow) a unique experiment includes the construction of an enterprise for the manufacture and assembly of large-sized object blocks, consisting of an experimental workshop of 186.6 x 150.8 m, equipped with innovative technological equipment, the manufacture of large-sized blocks of full factory readiness weighing up to 65 tons, the residential buildings assembly of large-sized blocks in sizes up to 15.5 x 7.5 x 3.3 m. The results obtained during the experiment confirm the large-scale prospects for the development of this direction as a highly industrial conveyor method of assembling residential buildings with high productivity and minimum erection duration [16].
At the same time, due to the pioneering nature, problems have been revealed at almost all stages of this technology for the construction of residential buildings, requiring their resolution by the integrated forces of research, design and construction organizations. Especially difficult are the tasks of forming the type of unified large-sized volumetric blocks, the development of modern space-planning solutions for buildings with the layout of large-sized blocks, the reasonable selection of their rational options for standard series, the use of high-performance automated means of mechanization of assembly operations, the creation of reliable and safe technological equipment for the stable positioning of blocks. To date, a clear methodology for modeling residential buildings erection of large-sized volumetric blocks has not been developed, linking the solutions to the above-mentioned tasks. But for this, first of all, it is necessary to determine the organizational and technological parameters that characterize the development of the technological process of erecting residential buildings of large-sized blocks, both as a whole and its individual operations [17, 18].
MATERIALS AND METHODS
The main organizational and technological parameters of an object erection are the total duration of construction, the duration of individual stages (periods) of construction, the labor intensity and machine intensity of work, the number of workers. These indicators are mandatory as part of construction organization projects and are determined by federal and territorial standards and indicators, and in some cases by analogous objects. For work production projects, the organizational and technological indicators given in construction organization projects are directive and represent the final technical and economic indicators of an object construction. Their calculation is based on determining the scope of work according to working drawings and estimates in units of measurement adopted in the estimated norms and prices [19].
Regarding the technology of residential buildings erection of volumetric large-sized blocks, the regulatory framework is just beginning to be formed, and therefore the definition of organizational and technological parameters and ranges of changes in their indicators depending on the conditions of work requires a special approach. Such an approach should be based on the generalization of the experience of the past years and the experiments currently being conducted, the accumulation and processing of the received statistical information with its subsequent correction as a result of the influence of scientific and technological progress [20, 21].
In order to determine the indicators of organizational and technological parameters of buildings erection of volumetric large-sized blocks, the MonArch group of companies carried out the timing of the installation of a residential building in the Desenovskoye settlement of Yakovlevo-2 village on the territory of the New Moscow (Fig. 1).
Fig. 1. General view on a building of large-sized volumetric blocks
This object is a four-story building with a plan size of 28.8 x 15.5 m. The building's volume and planning solutions form 7 blocks each, of which blocks B1, B2 and B3 are presented in 2 copies, and block B4 in one copy (Table 1), the height of all blocks is 3.3 m. The location of the blocks and the sequence of their installation on the ground floor are shown in Fig. 2, in which the fraction is indicated — in the numerator the number of the block, in the denominator — the number of its installation.
On all subsequent floors, the arrangement and installation sequence of blocks is similar to the scheme of the first floor (Table 2).

A Liebherr LTM 1650 crane with a maximum lifting capacity of 650 tons was used as a lifting-and-carry vehicle. The telescopic boom of the crane has a length from 16.7 to 80 m. The crane was used in modification T3, T3Y. Modification of the crane T3Y has a telescopic boom from 33.9 to 54 m. At R = 5 m, L. = 33.9 m,
min ' boom 7
and at R = 52 m, L, = 54 m1. The advantages of
max ' boom &
this powerful crane should also include high maneuverability and a large service area.
The main installation operations included:
• rigging, related to block preparation for lifting (traverse preparation, slinging);
• mounting, consisting of lifting (moving), aiming, orientation, installation, alignment, block fixing.

All information on the installation processes timing was summarized in the form of a report, a fragment of which is given in Table 3.
In work production process, rigging operations included slinging blocks (3-15 min), lowering and uncoupling the traverse grips (3-17 min), bringing the traverse to the storage area for unslinging the four extreme slings (4-10 min).
When performing the actual installation operations, the time spent was distributed as follows: bringing a block to installation location into design position (10-27 min), lowering the block (8-17 min), boom lifting with a turn to a location of a block (5-8 min), block lifting and turning (3-6 min).
A certain amount of time was spent on related operations, such as beating off swells on the supporting embedded parts (9-27 min), screwing — unscrewing fittings and tensioning chain slings to determine the center of gravity of a block (26 min). Unforeseen circumstances also arise related to difficulties in block installing into design position, for example, due to loose communication (27 min).
As a result, the duration of installation of large-sized volumetric block per floor was:
• 1st floor — 5.0 hours;
• 2nd floor — 4.7 hours;
• 3rd floor — 3.4 hours;
• 4th floor — 3.1 hours.

The roof installation of a building consisted of installing four covers in 1.1 hours.
Thus, the total duration of installation of the four-story building was 17.3 hours.
RESULTS OF THE RESEARCH
The final results of the timing showed that, despite the floor-by-floor use of identical types of large-sized blocks, their symmetrical arrangement and the same sequence of installation, as well as absolutely equal working conditions, there is a significant variation in floors arrangement duration. So, the maximum installation time of one floor is 5.0 hours (1st floor), and the minimum time is 3.1 hours (4th floor). The analysis made it possible to establish that the main reason for such a spread of duration indicators is mainly due to non-compliance with a clear sequence of installation operations and lack of practical experience. A certain negative role was played by the use of a non-automatic traverse, which slightly increased labor costs. At the same time, it should be borne in mind that the duration of installation of the 1st floor will be slightly higher than the duration of installation of each subsequent floor due to the specific conditions of installation of blocks on the foundation of the underground part of a building.
The materials of this timing are the first statistical data, based on which it is possible to deduce the dependence "the building erection duration — the number of large-sized blocks installed, taking into account the roof arrangement". Such dependence, of course, reflects the features and conditions of work production on erection of this particular building, but it can also serve as a predictive guideline for further solving scientific and practical problems.
It is advisable to present three estimates of building erection duration of large-sized volumetric blocks, which will be able to take into account a wide variety
of work options. Such assessments are pessimistic, satisfactory, optimistic.
The pessimistic assessment provides for the most unfavorable working conditions — lack of practical experience, use of mechanical technological equipment, displacement of gravity center and blocks offset, tightness on a floor, cutting of concrete flows, etc.
The duration of a block installation is defined as:
t ' = -

= 0.76 hour,
(1)
here t — duration of a block installation, hour (with a pessimistic assessment); t — maximum duration

of blocks installation per floor, hour; m — number of floors; t — duration of roof arrangement, hour; N — number of blocks for a building.
Then the indicator of the pessimistic assessment of the duration of a building installation, floor(s) arrangement will be:
T ' = 0.76n,
(2)
here T — duration of a building, floor(s) installation, hour (with a pessimistic assessment); n — number of blocks per building, floor(s).
A satisfactory assessment is focused on normal working conditions, but with the possible appearance of difficulties that cause additional labor and time costs. The duration of a block installation is equal to:

An optimistic assessment is calculated for the clear implementation of technological operations of the installation process during the entire duration of an object erection. The indicator of the duration of a block installation is expressed as:

T '" = 0.48 n,
(6)
here T" — duration of building, floor(s) installation, hour (with an optimistic assessment).
The labor intensity of large-sized volumetric blocks installation includes the total labor costs associated with the installation process, and it is recommended to determine it by the formula:
Q = ( + ?2 )P + ?3
Tß4j
j=1
(7)
here Q — labor intensity of blocks installation, man hours; ql — labor costs for a crane delivery to site, man hours; q2 — labor costs of machinists and crane maintenance workers, man hours; p — number of cranes; q3 — labor costs of installers for preparation of technological equipment, man hours; q4j — labor costs of installers for blocks installation on the j-th floor, man hours.
CONCLUSIONS AND DISCUSSION
Long-term construction practice has confirmed the technical feasibility and economic efficiency of residential buildings erection of volumetric blocks of high or full factory readiness as an important highly industrial direction of housing stock reproduction. In this regard, industrial production and conveyor assembly on construction sites of large-sized volumetric blocks should receive mass development, allowing to solve large-scale housing construction tasks in any natural and climatic conditions in a short time and with high quality.
At the same time, the development of building construction of large-sized volumetric blocks will require huge capital investments and, first of all, the formation of integrated efforts of research and design organizations to create appropriate industrial enterprises equipped with advanced robotic technology, and system solutions for the typification and unification of blocks, the development of modern volume planning and structural solutions of buildings, the creation of specialized transport and installation equipment and reliably positioned technological equipment.
The first steps, which have no analogues in the world, were taken by the MonArch group of companies, who took upon themselves the pioneering development of this technology of the future and at the same time revealed the entire complex of operational tasks, the solution of which will allow the construction industry to switch to buildings erection of large-sized blocks. One of such key tasks is the development of adequate organizational and technological solutions, as a decisive factor in the high efficiency of construction production. The approaches proposed in the article to determining the parameters of such organizational and technological solutions are initial and at the same time reflect the achieved level of production in this area, and they can be extended to other regions that have begun the construction of buildings of large-sized blocks.
