To put it briefly, architects are some of the key people in the construction team who are responsible for bringing the client’s vision to life, by way of construction plans and technical documents.
3,Structural Engineer
Once architects are finished with the project’s design, it’s the job of the structural engineer to ensure buildings remain strong and safe.
They are responsible for any structural failure, so they have to supervise the material selection, structural integrity, and field workers’ performance.
That’s why they don’t just sit in the office making designs and calculations. They also need to visit sites and ensure their plans are being implemented correctly.
you can find structural engineers on various construction sites, from residential projects and hospitals to bridges and offshore rigs.
They need to use their knowledge to create safe, solid, and durable structures in every construction industry sector.
The main part is solving problems creatively and efficiently, but most importantly, it’s doing everything as a part of a team.
Furthermore, a professional structural engineer is trained to use mathematical and engineering concepts to solve highly complex design structures.
Also, they need to use the same calculations to predict how the building will act throughout its lifespan.
All in all, any construction team can greatly benefit from the input and expertise of a structural engineer to create safe and sound buildings.
4,Designer
A designer in construction is anyone who prepares or modifies designs for construction projects.
Designs typically include sketching building plans, specifications, drawings, and other relevant documentation.
Now, at first glance, the responsibilities of a designer are similar to that of an architect.
In both roles, they create designs for structures before construction, examine building codes and project requirements, and communicate with clients.
The main difference is that anyone can assume the role of a designer, while only registered and trained individuals can call themselves architects.
Basically, every architect can be a designer, but not all designers are architects.
Designers need extensive knowledge and experience concerning building codes and regulations, construction industry standards, and technologies required to perform their job correctly.
They use this to turn clients’ ideas into working structure drafts. Designers should also be flexible enough to alter their plans according to the client’s needs.
Keep in mind that the designer’s main responsibility is to ensure their advice and plans result in a solid structure compliant with the building code.
5,Construction Project Manager
A project manager is in charge of overseeing a construction project from start to finish.
They plan, schedule, and monitor every aspect of a construction project to ensure it is completed on time and within budget.
The scope of the project manager is large because they need to be involved in every aspect of the construction project, excluding the construction work itself.
Here are some of their duties:
Drawing detailed project schedule, budget, and resources
Establish project goals and objectives
Selecting and hiring a project team
Negotiating with contractors and suppliers
Resolving issues or delays
Communication with employees and clients
Writing bids for tender
Reporting to clients on project’s progress.

He also adds that if you’re a detail-oriented person, good at solving problems on the fly, can orchestrate people, and handle surprises that come up regularly, you have what it takes to become a successful project manager.
Since project managers oversee every phase of the construction project, they’re invaluable to any construction team.
6,Construction Superintendent
Every superhero needs a sidekick, so project managers have superintendents.
In general, they have overlapping responsibilities: managing and overseeing construction projects and ensuring safety, schedule compliance, and budget control.
But while project managers mostly operate from the office, superintendents are usually seen on the job site.
Superintendents develop a schedule, oversee the workers’ performance, and manage communication and information from the office to the field.
superintendents are mediators between the office and the field and ensure all plans and ideas from the office are built properly.
While they work alongside construction workers, superintendents are primarily concerned with monitoring project quality, while worker management is the domain of a general foreman.
To become a superintendent, you need at least 10 years of experience, in addition to great communication and time management skills.
A good superintendent is analytical, an excellent problem-solver, and good at handling pressure.
7,General Foreman
In some construction companies, you’ll see that the roles of a superintendent and general foreman are fused into one. So, it’s not uncommon that these titles are used interchangeably.
Yet, there are slight differences you need to keep in mind.
General Foreman is in charge of the day-to-day operations on the construction site. They are directly involved with the performance and oversee the entire construction workforce.
This means they need to wear a lot of different hats.
First, becoming a safety instructor is one of the most important tasks as a general foreman.
This means they must have safety discussions with workers, ensure everyone has the appropriate safety gear, and follow safety procedures.
Basically, they’ll have to establish a good working culture and maintain the crew’s morale, which also includes having disciplinary talks with people and informing them about the company’s expectations.
More precisely, he’s in charge of the crew’s time sheets and filling out paperwork, among other things.
But they all agree on one thing: as a general foreman, you’re the “eyes and ears” on the ground for the company.
You need to establish priorities because everything you do affects the company and the workforce.
8,Site Clerk
Site clerk (also known as field engineer) is an entry-level position, ideal for recent graduates who want first-hand experience in the construction industry.
They work alongside the general foreman or superintendent and act as their assistants on the construction site.
Now, while technical skill in construction is not necessary for this role, to successfully carry out their duties, site clerks need a good understanding of all aspects of construction.
They need to keep the whole project’s picture in mind while working on details daily.

✍ Good evening guys we will be releasing an introduction to wind loads in our country context the coming sunday
Stay tuned😊
@plusdesign
Stay tuned😊
@plusdesign
Wind Loads in our country's context
In some areas, wind load is an important consideration when designing and building a structure. Wind load is the load in pounds per square foot, placed on the exterior of a structure by wind. This will depend on:
The angle at which the wind strikes the structure
The shape of the structure (height, width, etc.)
Preventing wind damage involves strengthening areas where buildings could come apart. The walls, roof and foundation must be strong, and the attachments between them must be strong and secure. For a structure to resist hurricane and weak tornadic winds, it must have a continuous load path from the roof to the foundation -- connections that tie all structural parts together and can resist types of wind loads that could push and pull on the building in a storm.
Wind exerts three types of forces on a structure:
Uplift load - Wind flow pressures that create a strong lifting effect, much like the effect on airplane wings. Wind flow under a roof pushes upward; wind flow over a roof pulls upward.
Shear load – Horizontal wind pressure that could cause racking of walls, making a building tilt.
Lateral load – Horizontal pushing and pulling pressure on walls that could make a structure slide off the foundation or overturn.
High wind pressures can collapse doors and windows, rip off roofing and roof decking and destroy gable end walls. Roof overhangs and other features that tend to trap air beneath them, resulting in high uplift forces, are particularly susceptible to damage. Broken windows and doors can expose the building contents to serious damage from internal wind pressures and water entry.

In our country Ethiopia the construction sectors are boost up due to modernization and industrialization. Wind speed data is prerequisite in designing of high raise buildings. In Ethiopia, the most common practice is to adopt design recommendations from European codes of practice which can be quite inappropriate due to the differences in climatical and topographical conditions. To foreground the present condition in Ethiopia, this paper tried to obtain the basic wind speed for different stations/towns. The basic wind speed data which is obtained from 159 stations are then compared with the design wind speed of 22 m/s according to EBCS 2015. Consequently, a basic wind speed zone map was prepared. The map was developed based on the basic wind speeds evaluated from the annual maximum records collected from each station. Hydrognomon Pythia-statistical analysis was done for different probability distributions. After their calculation the best fitting distribution between empirical and theoretical data was chosen using Kolmogorov-Smirnov test. The findings are clearly showing that the magnitude of the operating basic wind speed was increased in 14–150% from the constant of 22 m/s. By using best fitted probability distribution methods of each stations, obtained result are ranging from 25 to 55 m/s in Ethiopia.

👉Bonding of Old and New Concrete?
🚧In construction, there always comes a time when there is a need to bond hardened concrete (substrate) with fresh concrete topping/overlay. The aim of this post is to explain how to bond old and fresh concrete successfully.
Furthermore, we will review the strength of the interfacial bond between old and new concrete based on laboratory studies.
⏺Proper bonding is very important for adequate performance when the fresh concrete topping is used to overlay an existing hardened concrete. This construction feature is usually found in bridge deck construction, concrete pavements, precast filigree slab, pile caps (in some cases) etc. Proper bonding between the substrate and the topping is not always guaranteed unless simple precautions are taken.
⏺For adequate bonding, it is very important to prepare the surface of the substrate adequately. The preparation of the surface usually involves:
📌Roughening the surface, and removal of all dirt, oil, grease, and loosened or unbonded portions of the existing concrete.
⏺By implication, the surface of the substrate should be hard, firm, clean, and free from loosened particles. This can be achieved by the use of chipping hammers, wire brushing the surface, etc.
📌After this is done, the exposed concrete surface can be cleaned by using pressurized clean water, air, etc. The man hours involved depend on the area of the surface, location, and the ease of cleaning (e.g reinforcement obstruction).
📌After surface preparation, there is usually a need to apply a bonding agent on the surface of the existing concrete in order to facilitate the bonding. Epoxy-based bonding agents are very popular for such operations. It is recommended that a bonding agent is applied prior to casting the fresh concrete. In essence, the procedure should be ‘wet-to-wet’ as the bonding agent should not be allowed to dry before the fresh concrete topping is placed.
📌In a research carried out by Vandhiyan and Kathiravan (2017), the compressive strength of monolithic and bonded concrete was compared using 150mm x 150mm cube specimens at 28 days. With an epoxy-based bonding agent, the compressive strength of the bonded concrete was about 5% less than the monolithic strength, while without the bonding agent, the compressive strength was about 28% less than the monolithic compressive strength.
📌Research has also shown that the moisture condition of the substrate affects the shear bond strength of bonded concrete. Shin and Wan (2010) investigated the interfacial bond strength of old and new concrete considering saturated surface dry (SSD) and air dry conditions. Saturated surface dry is a condition in which the concrete contains moisture that is equal to its potential absorption, without the surface being wet or damp.
📌At a water/cement ratio of 0.45 (for the topping concrete), the shear bond strength at the interface was about 44% greater when the substrate was at SSD condition than when it was air dry. At a water/cement ratio of 0.6 for the topping layer, an increase in shear bond strength was recorded, but there was a reduction in the compressive strength of the concrete.
⏺So the recommendation in this article is that when casting a topping layer of fresh concrete on old concrete, adhere to the following guidelines;
(1) Prepare the surface properly
(2) Make sure that the substrate is at saturated surface dry condition
(3) Use a bonding agent and follow the manufacturer’s technical recommendation properly.
