Preparing Source Data

Initial data for the execution of the course project:

Construction area - Usinsk;

Soil conditions of the construction site - slags;

Foundation - prefabricated strip block;

Bearing walls and partitions - brick;

Other data - on the standard design passport.

The thickness of the outer walls is 64 cm.

Determining the depth of the foundation is necessary to calculate the depth of the pit and, therefore, its dimensions in plan.

Calculation is carried out according to SNiP 2.02.01-83 *

The normative depth of freezing is determined by the formula: dfn=d0*√Mt

For clay soil and loam d0 = 0.23

Sum of average monthly negative temperatures Mt = 80.5 (as per SNiP 23.0199)

dfn=0,23*√80,5=2,06 м

Kh=0.5 coefficient at the design internal temperature of tv = 200C and floors on soil

Design freezing depth: df = kh * dfn = 0.5 * 2.06 = 1.03 m

Groundwater level is taken as dw = 3 m

At dw≤df+2=1,03+2=3,03 m and clay base the depth of foundation laying is accepted as not less than df = 1.03 m

Finally we accept the depth of foundation bottom laying d = 1.2 m.

Selection of production method and determination of excavation quantities

We choose the type of development - different depth of the foundation pit;

Soil category for all types of works and construction machines - II;

In clay soils at d≤1,5 m, a pit with vertical walls is accepted, their attachment is not required;

The groundwater level of the UHF = 3 m, d = 1.2 m≤UGV1=2 m, therefore, all withdrawn soil can be considered dry, which means that waterfall and drainage are not required;

Distances from the axes of the outer walls to the edge of the foundation are 0.55 m. Due to the need to lower people into the pit, we increase its size by 0.7 m in all directions. The total dimensions of the pit in the plan are more than the dimensions of the building in the axes by 0.55 + 0.7 = 1.25 m in all directions.

Based on this, the area of ​ ​ the pit will be 2769.95 m2.

The estimated scope of work is about 3400 m3/month (to be defined further in the BOQ, as well as all other earthworks), therefore we choose a bulldozer with a capacity of 75,100 liters. from., excavator with a ladle volume of 0.5 m3.

Development of the site construction schedule

First of all, it is necessary to assign the number of grips for each complex of works.

Justification of number of grips

A. Earthworks

In buildings of up to 4 sections are carried out in 1 capture

B. Construction of foundations

The leading process of the complex is the installation of basement wall blocks and foundation cushions. Therefore, we divide the complex as a leading process into 3 grips.

B. Brickwork of the walls

We break each floor into 3 grabs. Total 6 captures

D. Installation of the above-ground part of 6 grips.

D. Roof arrangement

Since the masonry of the parapet is not divided into grabs, it makes no sense to divide the roof structure on them, because this will not lead to a combination of work - 3 grabs.

E. First stage plumbing

They are planned by grips with a step equal to the rhythm of floor installation. Take 3 grabs.

J. Electrical works of the first stage

They are planned by grips with a step equal to the rhythm of floor installation. Take 3 grabs.

Z. Filling of openings

Due to the short duration (4 days), it is possible to divide only 3 grabs by the number of floors.

K. Plaster works

It is recommended to lead on the entire floor. We take 3 grabs.

L. Malyarny works

We take 3 grabs.

M. Floor arrangement

Similar to plaster works - 3 grips.

H. Inner wall lining

O. Second Stage Plumbing

P. Electrical works of the second stage

P. Preparatory work

C. Landscaping and landscaping

T. Preparation of the object for delivery

N-T complexes, like painting work, are carried out outside the stream, conditionally divided into 3 traps

Evaluation of technical and economic parameters of the initial version of the project construction schedule

1. Design duration of works Tp = 75 days satisfies the SNiP 1.04.0385 * conditions, according to which the norm of construction duration of this facility taking into account the coefficient 1.2 (for the Republic of Komi) is 7 * 1.2 = 8.4 mes

2. Average number of workers per CMR:

NCP = QDP/t = 3133/75 = Human 42

3. Uneven labour force utilization:

KHEP = Nmax/NCP = 62/42 = 1.5 < 1.7

therefore, no optimization of the original variant is required.

4. Work alignment factor:

KCBM=∑tpi/Tp=183/75= 2.4

therefore, the work is mainly carried out in parallel.

The final version of the schedule is contained in Annex 1 of the A1 sheet. Also, the schedule of labor movement and the schedule of driving machines and mechanisms are executed in the appendix.

Object Construction Plan Design

Design of rational organization of main production at the facility

The justification of OTP for the main production at the facility is primarily a study of the work of leading construction and installation machines, primarily the binding of the installation crane.

Crane selection according to technical parameters was performed during scheduling:

Installation crane - Potain K-30

Maximum lifting capacity Qmax = 6 t;

Maximum boom span 70 m;

Maximum hook lifting height is 83.7 m;

Turning radius - 4 m

Cross-reference of crane

During the zero cycle:

For clay soils with a pit depth of 1 m, the smallest distance from the pit brow to the crane support is 3.2 m; to the axis of rotation 3.2 + 4 = 7.2 m.

During the construction of the above-ground part of the building:

Distance from crane motion axis to projecting parts of building

B = Rp + lBz = 4 + 0.7 = 4.7 m.

Crane Longitudinal Snap

By specification, we determine that the mass of the element moved to the farthest corner of the building is 3.35 tons (slab). According to the cargo characteristic of the crane, we determine the maximum boom span, in which the crane is able to lift a cargo weighing 3.35 tons - 60 m.

You can do with one crane parking lot, since all elements of the building can be installed from it. Thus, the arrangement of crane tracks is reduced only to the arrangement of crane parking.

It is also necessary to provide the possibility of mounting structures closest to the rotation axis of the crane. The minimum working span of the boom during installation of the floor slab is 4 m. As per the conditions of transverse binding, the crane is located no closer than 7.2 m from the projecting parts of the building, this condition is fulfilled .

Definition of crane hazardous area

Maximum working span of boom lmr = 60 m

Length of cargo transferred at maximum working departure dp = 6.3 m

Since the height of the building is 9.35 m, the hook lifting height is not the maximum value (83.7 m), but the value is less than 20 m. Therefore, the additional distance lbez = 7m

Crane hazardous area radius: Rop = lmp + dp/2 + lbez = 70.15 m

The width of the roadway is 3.5 m (one-way movement when using high-capacity vehicles). At rounding points, the width is 5 m. The minimum radius of the rounding is 12 m.

Parking of the crane is provided from inventory HLB slabs, the roadway is dirt, reinforced with slag.
