Zhejiang A high-rise Hotel measurement construction scheme
**The hotel is located in the center of Lincheng New District, * * City, at the northwest corner of the intersection of Qiandao Road and National Highway 329, and at the east and west sides of Qiandao Road respectively with the new * * Municipal Government Building. This project is a key project in * * City. The base has a total land area of 108045 ㎡, a building area of 83269 ㎡, one floor underground, 22 floors above ground tower, 88 meters high main building, three floors podium, and 16.5 meters high podium building, including 63036 ㎡ above ground and 20233 ㎡ underground. The civil air defense project is located in the square in front of the proposed project. It is an excavation type underground floor with a total construction area of 5755 ㎡. The relative absolute elevation of the project ± 0.000 elevation is 5.000 m, and the relative elevation of the natural floor is - 2.800 m. The podium structure of the project is reinforced concrete frame structure, the tower structure is reinforced concrete frame shear wall structure, and some parts are steel reinforced concrete columns. **The whole project of the Grand Hotel is novel and solemn, and will become one of the landmark buildings of * * City after completion. Due to the large floor area of the buildings in the project, the complex plane and elevation combination and large level dislocation, and the complex construction survey, the impact of size changes such as length and arc should be fully considered to reduce the cumulative error. In particular, there are many column beam nodes on the upper part of the structure, and the elevation control and axis positioning design of high-rise floors are strictly required. As the first process of project commencement, surveying and setting out always runs through all construction stages of the whole project, and its correctness is particularly important. In order to guide the project construction and ensure the project quality, we believe that the survey work should be carried out from the whole to the local, with high precision control and low precision procedures.

The whole project is composed of a 23 storey main office building above the ground, a three storey podium and a basement. Construction technology I, GRC slope making layer construction technology (1) Base course cleaning: clean the loose debris on the upper surface of the structural layer, and shovel the ash and other cohesive debris protruding from the base course surface, without affecting the effective thickness of the slope making layer. (2) Pipe root plugging: pipe root, deformation joint and roof warm trench wall root out of the roof shall be treated before large-scale slope making. (3) Proper watering on the surface of the base course is mainly beneficial to the combination of the base course and the slope making layer, but it is not allowed to sprinkle too much water to avoid affecting the drying of the slope making layer surface, so that the water vapor will be trapped after the construction of the waterproof layer, resulting in hollowing of the waterproof layer. (4) Snap line for slope making: according to the height of the slope and the flow direction, find out the direction of the layer slope, determine the thickness range of the slope making layer, and snap ink lines on the peripheral daughter walls. (5) Sticking point elevation: according to the slope requirements, draw a line to make slope, generally according to the 2-3m sticking point elevation (sticking ash cake). (6) Determine the specific gravity: the specific gravity shall be controlled between 1.25 and 1.3 according to the design requirements. (7) Pouring: it shall be constructed as a whole. During construction, the specific gravity of foaming agent shall be adjusted at any time with an electronic scale. (8) Floor leveling; Before the initial setting of the foaming agent slope making layer, the slope making layer shall be leveled with aluminum alloy, and the gradient shall be controlled. (9) Joint cutting: the position of the dividing joint of the slope making layer shall be set according to the column spacing and ≤ 36 square meters. (10) Curing: the slope making layer can be watered for curing 12 hours after leveling, and the general curing period is 7 days. After drying, the next process can be started.

Nanjing A high-rise Office building survey construction scheme
The construction site of the project is narrow and small, and the plane geometry is complex. The outer side line of the main building is connected into an ellipse by a number of arcs with different centers and radii; The cylinder wall is also curved, which brings great difficulties to the project positioning and setting out. For this reason, we set up a special survey and setting group to organize the implementation. Through analysis and comparison, first establish a closed traverse control network in the whole field around the foundation pit according to the off-site positioning control points, and then select the control points on the traverse network to conduct the axis survey. Its advantages lie in flexible selection of control points, good intervisibility conditions, convenient and simple observation and calculation, and quick recovery of control points that are accidentally damaged during construction. The survey of the traverse network shall be carried out according to the technical requirements of the first-class traverse. However, with the rise of the floor, the traverse control line point and the floor can not be seen from each other, so it is necessary to set up control points inside the building. There are four internal control points in total. The setting out of the floor axis is carried out according to the control network composed of internal control points. Because the installation and positioning of steel reinforced columns require high accuracy. A multi-function, high-precision and high-speed total station is used. The vertical survey of internal control points adopts the laser theodolite zenith method, and its accuracy is fully in line with the requirements of the Code for Design and Construction of Reinforced Concrete Tall Buildings after analysis. The setting out of the arc beam and wall shall be carried out according to the internal control line and the coordinates of the points on the arc line, and the deviation shall be controlled within the specified range.

Shanghai A high-rise Comprehensive building survey construction scheme
The measurement process is closely related to the construction process during the project construction, and the quality of the measurement work is directly related to the final quality of the entire project. (1) For this project, the survey work has the following characteristics: a. The basement structure of the construction project covers a large area of 128mX70m. Therefore, the divisional construction inevitably brings about the problem of plane axis connection between the construction areas, and the requirements for the overall axis unification are relatively high; b. The excavation depth of the basement of the construction project is - 16m, and multiple supports are set, so it has a certain impact on the intervisibility of the underground structure measurement; c. The building structure adopts the inner cylinder and outer frame structure, and is composed of two material systems of steel and concrete. Therefore, in the process of structural construction, requirements are put forward for the plane and elevation uniformity of the two construction subcontractors. Due to the above characteristics, how to ensure the unity of the axis system of each construction area has emerged; How to overcome the limitation of intervisibility conditions and efficiently control the axis of the lofting construction plane; How to coordinate a series of key points such as the difference between the plane and elevation during the construction of the two material systems from the perspective of the general contractor.
