13.1 Прочитай и письменно переведи текст STRUCTURAL ENGINEER:
Structural engineers analyse, design, plan, and research structural components and structural systems to achieve design goals and ensure the safety and comfort of users or occupants. Their work takes account of safety, technical, economic and environmental concerns, but they may also consider aesthetic and social factors.
Typical structures designed by a structural engineer include buildings, towers and bridges. Other structures such as oil rigs, space satellites, aircraft and ships may also be designed by a structural engineer. Most structural engineers are employed in the construction industry, however there are also structural engineers in the aerospace, automobile and shipbuilding industries. In the construction industry, they work closely with architects, civil engineers, mechanical engineers, electrical engineers, surveyors, and construction managers.
Structural engineers ensure that buildings and bridges are built to be strong enough and stable enough to resist all appropriate structural loads in order to prevent or reduce loss of life or injury. They also design structures to be stiff enough to not deflect or vibrate beyond acceptable limits. Fatigue maybe an important consideration for bridges and for aircraft design, or for other structures which experience a large number of stress cycles over their lifetime. Consideration is also given to durability of materials against possible deterioration which may impair performance over the design lifetime.

13.3 Прочитай и письменно переведи текст SURVEYING AS A CAREER:
1. The basic principles of surveying have changed little over the ages, but the tools used by surveyors have evolved tremendously. Engineering, especially civil engineering, depends heavily on surveyors.
2. Whenever there are roads, railways, reservoir, dams, retaining walls, bridges or residential areas to be built, surveyors are involved. They establish the boundaries of legal descriptions and the boundaries of various lines of political divisions. They also provide advice and data for geographical information systems, computer databases that contain data on land features and boundaries.
3. Surveyors must have a thorough knowledge of algebra, basic calculus, geometry, and trigonometry. They must also know the laws that deal with surveys, property, and contracts. In addition, they must be able to use delicate instruments with accuracy and precision. In the United States, surveyors and civil engineers use units of feet wherein a survey foot is broken down into 10ths and 100ths.
4. In most states of the U.S., surveying is recognized as a distinct profession apart from engineering. Licensing requirements vary by state, however these requirements generally all have a component of education, experience and examinations. In the past, experience gained through an apprenticeship, together with passing a series of state-administered examinations, was required to attain licensure. Nowadays, most states insist upon basic qualification of a degree in surveying in addition to experience and examination requirements.

13.5 Прочитай и письменно переведи текст MODERN THEODOLITES:
In today’s theodolites, the reading out of the horizontal and vertical circles is usually done electronically. The readout is done by a rotary encoder, which can be absolute, e.g. using Gray codes, or incremental, using equidistant light and dark radial bands. In the latter case the circles spin rapidly, reducing angle measurement to electronic measurement of time differences. Additionally, lately computer-controlled display sensors have been added to the focal plane of the telescope allowing both auto-targeting and the automated measurement of residual target offset. All this is implemented in embedded software.
Also, many modern theodolites, costing up to $ 10,000 apiece, are equipped with integrated electro-optical distance measuring devices, generally infrared based, allowing the measurement in one go of complete three-dimensional vectors which can then be transformed to a pre-existing co-ordinate system in the area by means of a sufficient number of control points. This technique is called a resection solution or free station position surveying and is widely used in mapping surveying. The instruments, “intelligent” theodolites called self-registering tacheometers or “total stations”, perform the necessary operations, saving data into internal registering units, or into external data storage devices. Typically, ruggedized laptops are used as data collectors for this purpose.

13.7Прочитай и письменно переведи текстFOUNDATIONS OF LOW-RISE BUILDINGS:
All foundations must transmit the building loads to a stable stratum of earth. There are two criteria for stability: first, the soil under the foundations should be able to receive the imposed load without more than about 2.5 centimetres of settlement and, second, the settlement should be uniform under the entire building. It is also important that the bottom of the foundation be below the maximum winter frost level. Wet soil expands as it freezes, and repeated freeze-thaw cycles can move the building up and down, leading to possible displacement and damage. Maximum frost depth varies with climate and topography. It can be as deep as 1.5 metres in cold continental climates and is zero in tropical and some subtropical areas.
The foundation systems for low-rise residential buildings are suitable for their light loads; nearly all are supported on spread footings, which are of two types — continuous footings that support walls and isolated pad footings that support concentrated loads. The footings themselves are usually made of concrete poured directly on undisturbed soil to a minimum depth of about 30 centimetres.
Foundation walls can be built of reinforced concrete or masonry, particularly concrete block. Concrete blocks are of a standard size larger than bricks and are hollow, forming a grid of vertical planes. They are the least expensive form of masonry — using cheap but strong material — and their large size economizes on the labour required to lay them. Their appearance and weathering properties are inferior to those of fired masonry, but they are satisfactory for foundation walls, in some places timber foundation walls and spread footings are used. Excavation for foundations is the most highly mechanized operation in this building type; it is done almost entirely with bulldozers and backhoes.

13.9 Прочитай и письменно переведи текст PIPE PILES:
Pipe piles are a type of steel driven pile foundation and are a good candidate for battered piles. Pipe piles can be driven either open end or closed end. When driven open end, soil is allowed to enter the bottom of the pipe or tube. If an empty pipe is required, a jet of water or an auger can be used to remove the soil inside following driving. Closed end pipe piles are constructed by covering the bottom of the pile with a steel plate or cast steel shoe. In some cases, pipe piles are filled with concrete to provide additional moment capacity or corrosion resistance.
In the United Kingdom, this is not generally done in order to reduce the cost. In these cases, corrosion protection is provided by allowing for a sacrificial thickness of steel or by adopting a higher grade of steel. If a concrete filled pipe pile is corroded, most of the load carrying capacity of the pile will remain intact due to the concrete, while it will be lost in an empty pipe pile.
The structural capacity of pipe piles is primarily calculated based on steel strength and concrete strength (if filled). The thickness of the steel considered for determining capacity is typically reduced by 1/16 in. compared to the actual pipe to account for corrosion. Steel pipe piles can either be new steel manufactured specifically for the piling industry or reclaimed steel tubular casing previously used for other purposes such as oil and gas exploration.

13.11Прочитай, переведи текст DOWNTOWN и расположи абзацы в правильной последовательности:
1. Now steel frame blocks are rising on a three part site being developed by Ballymore for mixed use, with offices, retail space and hotel floors above. Largest will be a development with two towers on the square site at the end, one of these a future landmark with 44 floors, the city’s highest building. Landscaped space will also be over a five-storey basement car park filling the whole 96,000 m2 space. To create this large volume and tower foundations, groundwork specialist Bachy Soletanche has been installing a deep contiguous piled wall around the site this summer. In recent weeks, as the large excavation inside got underway inside, it has been back on site to install a line of ground anchors in the wall.
2. Birmingham’s latest development includes a 44 storey-tower with a five storey basement. Bachy Soletanche is just finishing the foundations.
3. “These are for temporary support of the wall during the basement construction,” explains contracts manager Steve Mallinson. “Once the concreted base slab and floors are in place they will provide all the structural support needed and the anchors will be cut through.” The tendons will remain in the ground afterwards. “We also had to do ten plunge columns for the site approach ramp within the main wall,” says Mallinson. These hefty steel H-section columns, surrounded by pea gravel inside their pile casings, are gradually being exposed again as the site excavation proceeds.
4. For the ten top-down piles Bachy installed a basic bored pile with casing and then used its special plunge column rig to achieve the 5 mm accuracy needed for positioning the I section steel columns.
5. Contractor PC Harrington is doing the excavation and base concreting at present. But until recently Bachy has unusually had the site to itself. “We were effectively a main contractor,” says Mallinson, “installing security and site welfare, arranging spoil disposal and concrete deliveries.”
6. Birmingham, England has long had a reputation as a windswept concrete jungle, the result of road focused re-development in the 1960s. But a wave of new development is modernising the city centre with friendlier mixed use schemes. One of the biggest is transforming a bleak space close to the Snow Hill station, the city’s second central railway station. For years the area has been mainly rough ground, used for car parking alongside a main road, with railway lines nearby and assorted 1960s concrete multistorey car parks.
7. It was a change, he says, not having to interleave between other work, though with two support cranes, two Bauer BG 22 piling rigs, spoil heaps, reinforcement deliveries and site accommodation to deal with, the site became full enough. As the 241 piles in the perimeter wall were installed he even had to block off two of three site entrances, which meant some careful logistics were needed.
8. For the 220 m length of the main wall, project design consultant WSP had opted for contiguous piles, “which is the right choice,” says Mallinson, “because the ground is dry and you don’t need any interlocking.” Piles are 750 mm diameter.
9. The obstacles were mainly several metres down and up to 3 m thick. To get through meant using the full strength of the Bauer rigs in straight boring mode — the dual purpose rigs could be converted for such work in about 24 hours and then drove through the hard material with tungsten carbide boring heads. “We had site investigation data but did further probe piles at various locations around the perimeter to work out what we could do with the CFA and what would take the harder cased bored work,” says Mallinson. In the end about 30% bored piling was needed, somewhat less than Bachy had estimated, which meant it came out ahead.
10. To get through this fairly soft ground should be relatively straightforward. Bachy hoped to work with continuous flight piling mainly, which is quick and economical. But there is always a but. On this site it was obstacles in the ground, remnants of the 1960s, including various road underpasses and subways. “A lot of it was grubbed out in a preparatory contract,” says Brown. “But there was some left where it would have caused undermining of the highway.”
11. But there is often another but. The sandstone and sand caused difficulties with both types of piling “because porous ground tends to suck the moisture out of the concrete,” says Mallinson. “That made it stiffer and harder to get the pre-made reinforcement cages in after the augur was withdrawn.” Bachy switched to a more fluid mix and a highly disciplined pile procedure where cages were positioned within a minute of the augur being withdrawn.
12. Snow Hill development includes 56,000 m2 of office space, a five-star hotel and 332 luxury apartments in a 44-storey tower, five major new public spaces which — it is hoped — will create a new core to Birmingham’s commercial heartland Kier Group is the main contractor with Arup heading up the mechanical and electrical engineering contract, while Alan Baxter Associates is the structures and highways consultant. Ballymore Properties is the developer of the Snow Hill project. It has worked on 22 city centre projects in Liverpool, Luton, Bristol and London. In London’s Docklands, current schemes include Pan Peninsula, Ontario Tower and Leamouth Peninsula.
13. A steel frame sitting on the casings had three sets of hydraulic rams for precision adjustment of the central steel while it was fixed with around 5 m of concrete at the pile base. Pea gravel fills the casing. The 12 weeks’ schedule met, Bachy retired for a month while the excavation began, returning in late October to begin anchoring. Some 70 anchors go in, a row of one every three piles. Each is 15 m long and 178 mm diameter, driven by a Casagrande M6 articulating rig.
14. Five strand reinforcement bundles from Diwidag are grouted into the bottom 6 m or so of the anchor which runs at a 45° incline into the sandstone. That too has gone to schedule and the site is now almost ready for the main works by contractor Altius.
15. The Snow Hill development as it will look.
The wall will hold back the ground which comprises a few metres of fill, then a 3—5 m thick sand layer which becomes weathered sandstone further down and gradually more competent rock. “The bedrock layer slopes from 2 m to 14 m down across the site and the piles must be up to 17.5 m deep,” says site engineer Mathew Brown, “though they average out a little less.”

Surveying or land surveying is the technique and science of determining the terrestrial or three-dimensional space position of points and the distances and angles between them. These points are usually on the surface of the Earth, and are often used to establish land maps and boundaries for ownership or governmental purposes. In order to accomplish their objective, surveyors use elements of geometry, engineering, trigonometry, mathematics, physics, and law.
Furthermore, a particular type of surveying known as land surveying is the detailed study or inspection by gathering information through observations, measurements in the field, questionnaires, or research of legal instruments, and data analysis in the support of planning, designing, and establishing of property boundaries.
It involves the re-establishment of cadastral surveys and land boundaries based on documents of record and historical evidence, as well as certifying surveys of subdivision plats/maps, registered land surveys, judicial surveys, and space delineation. Land surveying can include associated services, such as mapping and related data accumulation, construction layout surveys, precision measurements of length, angle, elevation, area, and volume, as well as horizontal and vertical control surveys, and the analysis and utilization of land survey data.
Surveying has been an essential element in the development of the human environment since the beginning of recorded history (5000 years ago) and it is a requirement in the planning and execution of nearly every form of construction. Its most familiar modern uses are in the fields of transport, building and construction, communications, mapping, and the definition of legal boundaries for land ownership.
Historically, distances were measured using a variety of means, such as chains with links of a known length, for instance a Gunter’s chain or measuring tapes made of steel. In order to measure horizontal distances, these chains or tapes would be pulled according to temperature to reduce sagging and slack. Additionally, attempts to hold the measuring instrument level would be made. In instances of measuring up a slope, the surveyor might have to “break” the measurement — that is, raise the rear part of the tape up ward, plumb from where the last measurement ended.
Horizontal angles were measured using a compass which would provide a magnetic bearing from which deflections could be measured. This type of instrument was later improved with more carefully scribed discs providing better angular resolution, as well as through mounting telescopes with reticles for more precise sighting atop the disc. Additionally, levels and calibrated circles allowing measurement of vertical angles were added.
The simplest method for measuring height is with an altimeter — basically a barometer — using air pressure as an indication of height, but surveying requires greater precision. A variety of means, such as precise levels, have been developed to do this. Levels are calibrated to provide a precise plane from which differentials in height between the instrument and the point in question can be measured, typically through the use of a vertical measuring rod.
With the triangulation method, one first needs to know the horizontal distance to the object. The height of an object can be determined by measuring the angle between the horizontal plane and the line through that point at a known distance and the top of the object. In order to determine the height of a mountain, one should do this from the sea level, but here the distances can be too great and the mountain may not be visible. So it is done in steps, first determining the position of one point, then moving to that point and doing a relative measurement, and so on until the mountain top is reached.

1. Monuments are the marks on the ground that define location. Pegs are commonly used to mark boundary corners. Small pegs in the ground and steel rods are used as instrument locations and reference marks, commonly called survey control. Marks should be durable and long lasting, stable so the marks do not move over time, safe from disturbance and safe to work at. The aim is to provide sufficient marks so some marks will remain for future reestablishment of boundaries. Examples of typical man-made monuments are steel rods, pipes or bars with plastic, aluminum or brass caps containing descriptive markings and often bearing the license number of the surveyor responsible for the establishment of such. The material and marking used on monuments placed to mark boundary corners are often subject to state laws/statutes.
2. The aim of cadastral surveys is to re-establish and mark the comers of original land boundaries. The first stage is to research relevant records such as land titles (deeds), survey monumentation (marks on the ground) and any public or private records that provide relevant data. The job of a boundary surveyor retracing a deed or prior survey is to locate such monuments and verify their correct position. Overtime, development, vandalism and acts of nature often wreak havoc on monuments, so the boundary surveyor is often forced to consider other evidence such as fence locations, woodlines, monuments on the neighboring property, parole evidence and other evidence.
3. Many properties have considerable problems with regards to improper bounding, miscalculations in past surveys, titles, and others. Also many properties are created from multiple divisions of a larger piece over the course of years, and with every additional division the risk of miscalculation increases. The result can be abutting properties not coinciding with adjacent parcels, resulting in gaps and overlaps. The art comes in when a surveyor must solve a puzzle using pieces that do not exactly fit together. In these cases the solution is based upon the research of the surveyor, and following established procedures for resolving discrepancies.
4. A total station or GPS (Global Positioning System) is set-up over survey marks which were placed as part of a previous survey, or newly placed marks. The datum is established by measuring between points on a previous survey and a rotation is applied to orientate the new survey to correspond with the previous survey or a standard map grid. The data are analysed and comparisons are made with the existing records to determine evidence which can be used to establish boundary positions. The distance of lines between the boundary corners and total station positions are calculated and used to set out and mark the corners in the field. Checks are made by measuring directly between peg places using a flexible tape. Subdivision of land generally requires that the external boundary is re-established and marked using pegs, and the new internal boundaries are then marked. A plat (survey plan) and description (depending on local and state requirements) are compiled, the final report is lodged with the appropriate government office (often required by law), and copies are provided to the client.

1. The height of the staff where the level beam crosses the staff is shown on a digital display. This type of level removes interpolation of graduation by a person, thus removing a source of error and increasing accuracy.
2. An automatic level, self-levelling level or builder’s auto level, includes an internal compensator mechanism (a swinging prism) that, when set close to level, automatically removes any remaining variation from level.
3. A modem theodolite consists of a movable telescope mounted within two perpendicular axes — the horizontal or tmnnion, and the vertical axis.
4. Measurement generally starts from a benchmark with known height determined by a previous survey, or an arbitrary point with an assumed height.
5. Half of the difference between the two positions is called the index error.
6. It is set up on a tripod and, depending on the type, either roughly or accurately set to a levelled condition using levelling screws. The operator looks through the eyepiece of the telescope while an assistant holds a tape measure or graduated staff vertical at the point under measurement.
7. Before its use, a l heodolite must be placed precisely and vertically over the point lo be measured — centering — and its vertical axis aligned with local gravity — levelling.
8. The optical axis of the telescope, called the sight axis and defined by the optical center of the objective and the center of the crosshairs in its focal plane, must similarly be perpendicular to the horizontal axis.
9. Their existence is taken into account in the choice of the measurement procedure in order to eliminate their effect on the measurement results.
As late as the 1990s the basic tools used in planar surveying were a tape measure, a theodolite and a level.
A theodolite is an instrument for measuring both horizontal and vertical angles. It is a key tool in surveying and engineering work, particularly on inaccessible ground, but theodolites have been adapted for other specialized purposes in fields like meteorology and rocket launch technology. _ . When the telescope is pointed at a desired object, the angle of each of these axes can be measured with great precision, typically on the scale of arcseconds.
Both axes of a theodolite are equipped with graduated circles that can be read out through magnifying lenses. The vertical circle should read 90° when the sight axis is horizontal, or 270° when the instmment is in its second position, that is, turned over or plunged. _ .
The horizontal and vertical axes of a theodolite must be perpendicular. The condition where they deviate from perpendicularity and the amount by which they do is referred to as a horizontal axis error. _ .
Any deviation from perpendicularity is the collimation error.
A horizontal axis error, a collimation error, and an index error are regularly determined by calibration and are removed by mechanical adjustment at the factory in case they grow large. _ .
A theodolite is mounted on its tripod head by means of a forced centering plate containing four thumbscrews, or in some modern theodolites, three, for rapid leveling. _ .
The level instrument is an optical instrument used in surveying and building to transfer, measure, or set horizontal levels. _ .
The instrument and staff are used to gather and/or transfer elevations (levels) during site surveys or building construction. _ .
_. This reduces the need to set the instrument truly level, as with a dumpy or tilting level. Self-levelling instruments are the preferred instrument on building sites, construction and surveying due to ease of use and rapid setup time.
A digital electronic level is also set level on a tripod and reads a bar-coded staff using electronic laser methods. _ .
