A Measured Survey is a detailed drawing showing the dimensions, locations, and permanent features of your property, which can be a building or land.
This type of survey is essential for identifying the layout of your property and its permanent attributes.
According to the Royal Institution of Chartered Surveyors (RICS), measured surveys are usually drawn up to a scale of 1:100 for buildings, 1:50 for listed buildings, and 1:250 for land.
The location of your property is determined by GPS (Global Navigation Satellite System) coordinates or can be created locally specifically for your property.
The positions are relative to their reference points, such as GPS or the local established control points.
The Land Registry emphasizes the importance of accurate location data, which is then used to establish the property’s boundaries and create a definitive record.
Permanent features are a crucial aspect of a measured survey, as they define the characteristics of your property.
Walls
Windows
Doors
Beams
Columns
Built-in cabinets/wardrobes
Ponds
Trees
Pavement
Street furniture
According to the UK’s Planning Portal, permanent features can be used to distinguish between buildings and land, and are often referenced in planning applications and insurance policies.
As highlighted by the Royal Institution of Chartered Surveyors (RICS), measured surveys provide a detailed record of these features, allowing for accurate assessments and decision-making.

If you want to undertake a measured building survey, a laser distance meter can be extremely handy and accurate. Laser measures come in smaller and larger sizes, with a variety of functions to suit homeowners and tradespeople or professionals: laser distance meters are frequently used by electricians, estate agents, contractors, surveyors, insurance loss adjusters, flooring professionals, plumbers, and the like for the everyday accurate measuring of buildings.
Using a laser distance meter is a convenient alternative to traditional tape measures. Simply line up the device at the end of the wall or doorway and aim the laser beam at the desired point. Press the button, and the device will display the length of the space measured on the screen. Some laser distance meters also feature calculator functions for adding distances together, calculating volumes and areas, and determining the length of materials needed for new carpeting.
There are several advantages to using a laser distance meter over a traditional tape measure. Digital laser technology allows for quick and efficient work without the inaccuracies caused by tape measures that are not straight or properly aligned. Additionally, laser distance meters enable solo work, as conventional tape measures often require two people. Measuring roof height is particularly challenging without a digital tape measure, and reading a digital display is generally easier than checking lines on a conventional tape measure.
Once you’ve got your laser distance meter and you’re confident using it, you’re ready to do your measured building survey. For this, you’ll need to make sure you’ve got paper, a clipboard, and a pen to hand, as you’ll need to write down all of your measurements really clearly and carefully. If you’re an architect, this process is second nature, but for most amateur surveyors, you will need to be careful to ensure high levels of accuracy. Some spare batteries, a camera, a traditional tape measure and work boots/a high visibility jacket might also come in handy depending on the location, too.

It pays to look around the whole building first, if you’re not already familiar with it. As you come to measure each room, sketch it out first on your paper, and add your measurements to the sketches as you go. Working in different colours for windows, steps, and wall heights can be useful so you don’t get confused by your sketches later.

As you carry out your measured building survey, you will need to be methodical. As you begin measuring, start at the door and work consistently either clockwise or anti-clockwise around the room, so you don’t miss anything. You will need to measure window heights, floor thickness (try around the stairs), wall thickness, elevations, and roof height and angle, too. Take as many measurements as you can, and then lots of photos too to help with the interpretation of your results when you’re done.
While it’s perfectly possible to carry out your own survey for DIY purposes, when it comes to planning permits, you will need a measured building survey from a qualified and professional measured buidling surveyor. Architects too will require accurate technical drawings which can only be produced by a professional.

Bricks in general
The size of bricks and blocks can make a big difference to the construction process because they are important materials. There are many types of bricks and blocks that could be used in construction, but there’s one size that affects how everything else will be built.

Stone is quarried and shaped, but it also often occurs naturally. Additionally, it was often used as it was found below cliffs or outcrops or on beaches, or from the general stones on or in the ground.

A side is another name for a stretcher or stretcher-faced panel.
Mortar is a type of material used to bind bricks and blocks together.
Bricks are made in different sizes, but in this text we’ll only focus on the standard metric brick.
Brick manufacture is complicated, because the final size of a brick can be slightly different from what you expect.
The nominal size of a brick is the difference between the working and coordinating dimensions.
The nominal size of a brick is the difference between the working and coordinating dimensions. The usual nominal size is 10 mm, with a layer of mortar into which the bricks are pressed when laid. Most often this nominal size is the thickness of six bricks or one inch- American units.
Our content is sized according to importance, rather than just by time.

The term nominal sizing refers to the size given by a manufacturer that allows for slight variation. The variations in size – larger or smaller – are generally given in British Standards. Variations on individual bricks may vary, as they’re allowed an extra few millimeters as they are pressed into the mortar, but they will fall between the dimensions width of 225mm and thickness of 75mm.

Durability of bricks
Durability is an important consideration when building in areas with freezing temperatures or high levels of salt. For a classification of durability, see BS 3921.
Durability is an important consideration when building in areas with freezing temperatures or high levels of salt. For a classification of durability, see BS 3921.
The durability of brickwork is dependent on two factors: resistance to frost and soluble salt content. Frost resistance falls into three classes: frost resistant (F), moderately frost resistant (M) or not frost resistant (O). Soluble salt content is classed as either low (L) or normal (N). So, one could have a brick that is frost resistant with normal soluble salts content and this would be classified as FN. Likewise, a brick that had no frost resistance and had low soluble salt content would be classified as OL.
Mortar joints
Mortar placed below or on top of bricks is called a bed. Mortar placed vertically in between bricks is called a perpend.

Coordinating sizes
Regularly spaced, matching sizes allow these bricks to be pieced together in a number of different ways. Building brickwork to the specific coordinate size is important for achieving the desired appearance.
Other elements like bits, lints, and window halves are manufactured to fit openings that are calibrated in whole or cut bricks.
When creating a brickwork design, you should make sure that the bricks are all the same size so they will fit properly.
The height of the lintel is 176 mm, or 3 x 65 mm.

The width of the window opening must be a multiple of half a brick, plus the perpends. This means that 8 × 102.5 + 9 × 10 = 880 mm or 4′ 10
Perforations that do not exceed 20% of the brick’s total volume; at least 30% solid brick across the width.

Bricks can be manufactured to fulfill many different functions, such as adding structural support, resisting moisture absorption, or being used as decoration.
The majority of bricks used are from the ‘All other’ category, but don’t have a problem resisting the weight of most buildings. That being said, it’s important to remember that there are limits for bricks when it comes to absorbing water. If bricks will be used for an external wall and you want them to resist weather, it would be foolish to use extremely absorbent bricks or let the absorption level for engineering bricks fall below those required by DPC. At the same time, if a DPC is not in place and you’re using less than average water-absorbing bricks, this might not be necessary and could actually end up causing problems down the road.

The vast majority of bricks used are in the “all other” category, but this compressive strength is perfectly adequate for all but the most severe loadings.
However, the water absorption should be limited if you need your external walls to resist weather conditions.
It would be foolish to build a wall that has bricks that can absorb lots of water if these bricks were going to become damaged from weather conditions.
On the other hand, if the brick is low on water absorption and you’re required to use drying agents, it might be an unnecessary expense.
Testing of bricks
Brick must be tested to comply with British Standards.
The tests typically include dimensions, soluble salt content, efflorescence, compressive strength, and water absorption.
Bonding of Bricks to form walls (types of bonds)
One of the first building concepts ever developed–bonding bricks together–is still being used today. This quality of a wall is created with layers and various patterns that change from course to course. You can mold your bonding pattern by changing the cut and whole bricks in these layers, or even by using bricks that are shaped differently than standard rectangles.
Cutting a brick in half can be tricky. It’s easy to draw out the lines correctly, but it’s not so easy to cut along the lines with precision. Fortunately, there is a simple solution that will work for any type of brick – even one that has been damaged or deteriorated. By cutting the brick along its half height, you create the perfect surface against which to rest other bricks. You could call this cut a ‘half batt’.
Building walls with straight vertical ends is possible because of the simple cut at the end of the brick.
English bond is a complex pattern used in situations where the wall has a thickness of 215 mm or one brick.
For walls thicker than one brick, a further development for bonding comes into play.
Wall Thickness
What are the thickness of walls
Stretcher or common bond
The point where two straight lines meet, called an intersection.
The right-angled corner of a wall, known as the quoin.

Only used for walls of half brick thickness, this is the only practical bond that can be used on a wall of this thickness. Though we’ll build ‘mock’ bonds of other kinds later. A little of that later.
Only show stretchers on the general face, with occasional applications at quoins, scuntions, and intersections.
Flemish bond
This bond is not so strong as English bond
It is used on walls made of one brick width.
Noting how the width of a secant varies in direct proportion to the wall thickness, one can see that
The decorative pattern on the face of walls shows alternate headers and stretchers in each course, with the headers centered under and over the stretchers in adjacent courses.
Quetta bond
Quetta bond
Quetta Bond
This drawing is the sectional bond. The hatched portion is a void, not the actual sectional bond. This is an attempt to produce a more weather-resistant form of wall than the one brick, solid wall commonly used in housing at the time without using any more bricks or splitting the wall into two layers joined with wall ties. This idea never took off because, although it does provide a way for moisture from outside to travel onto the inside surface of the wall, it adds another step to production and slows down construction.

Bricks are the most common type of masonry wall we see today. They’re all layed on edge (or stacked vertically). Due to this, our walls are 1 and a half bricks thick.
When building bond with bricks on edge, there are a few things to keep in mind:
Bricks should have plain beds – no raised frogs, cavities or perforations.
If the wall is to be rendered or plastered, choose bricks with shallow frogs or small perforations
If the wall is covered over in some other way, then the size of a frog etc. doesn’t matter.
Coverings could include vertical tiles, slates, or board-like structures that are half an inch thick.
This wall would solve the problem of moisture crossing the wall.
This type of bond uses bricks and concrete. Reinforcing rods are installed in weakened brick bonds to strengthen the walls.
For example, for brickwork that is complete and mortar has hardened, concrete is then poured into the gaps between the bricks and rods.
This type of construction may not be an economically-feasible solution for keeping out the weather once the cost of overcoating is added, but it is a good option for noninhabitable buildings or garden walls because they don’t require as much upkeep.

Rattrap bond
Rattrap Bond
Like the Quetta bond, the Rattrap bond are laid on edge, which can result in an interesting face pattern. The following information about Quetta bond applies equally to Rattrap bond, with a very low chance of keeping out weather effects. A stronger bond than Quetta, Rattrap is often used for industrial or agricultural buildings. It can be made more weatherproof by over-cladding, and the bond usually involves one stretcher to one header, as seen in the illustration above
Conclusion
I hope this answers the different types of brick bonds, the sizes and common misconceptions about working with bricks. I sure have learnt the two new bonds of Quetta and rattrap bonds from doing this research.

Using the Correct Engineering Surveyor
Using the Correct Engineering Surveyor
The importance of hiring a fast, efficient, and knowledgeable engineering surveyor cannot be overstated. A seasoned engineer will be able to perform a measured building survey within an agreeable time frame and return quality drawings fast. As many projects are often performed within an extremely tight time frame, a good surveyor is one of the key professionals that should always be used. From providing a topographical survey and addressing ownership boundaries to creating detailed plans that are able to pass local building codes, an experienced surveyor is a critical component. Since there are a number of these professionals within the industry, it is wise to only choose those with the best reputation and that are known to accommodate demanding schedules.
Unbiased Analyses
Unbiased Analyses
One of the issues that may be encountered during any project is the ability to obtain an unbiased analysis in terms of workload, price, and projected completion dates. Any bias during these stages can not only lead to cost overruns, but could cause the reputation of the architectural firm to come into question. Customers require pragmatism and clarity in terms of all such estimates. In fact, a “no-nonsense” approach far outweighs one that will require an adjustment further down the line. There is simply no room for salesmanship once a job begins.

The process of keeping a customer happy should never end once the job is procured and the contract is signed. This is often a costly mistake of many firms. While the project itself may have been won, there is no guarantee that future business will be generated. Although this is obviously important through the actions of the architectural firm itself, we should note that the contractor will also be present on the job site a good portion of the time. Securing a reputable, communicative and knowledgeable contractor is therefore another absolutely essential step. These attributes should be balanced with speed; a fast contractor is one who will keep the customer happy during all phases of the project.
