The role of Site Engineer & Project Engineer in a construction project

Site engineers and project engineers frequently work in tandem on a job performing various things. Both play important role for major projects with equally significant liabilities.

Comparing Site Engineers to Project Engineers: Both the site engineers and project engineers take diverse liabilities for accomplishment for different types of construction projects.

Site engineers have sound technical skills which can be applied for specific engineering aspects of the project. Project engineers supervise the general operation of the project. They acquire the resource orders, deal with clients, and coordinate with designers and other engineers.

Given below, the basis differences among site engineers and project engineers :-

Liabilities of Site Engineers vs. Project Engineers

Site engineers perform according to a designer's plans, engineer's specifications and city codes to execute their jobs. Conversely, the project engineers perform very intimately with management and planners in an consultative manner to produce blueprints that fulfill the objectives of the clients as well as city and state codes.

Site Engineers: The site engineers may possess an office somewhere, but in several occasions they are active at the job site ensuring specific jobs are accomplished perfectly and with adherence to code.

These engineers examine that a building's wiring is completed properly, the plumbing will not leak, or the walls will not fall. They also have to rationalize modifications to orders, redrawing alternate plans and settling technical problems instantly and within the budget.

Given below, the liabilities of a site engineer:

• Performing as the top technical advisory on construction site
• Surveying, arranging and leveling the area for work
• Allowing planning data among managers, engineers and designers
• Tutoring trainees as well as junior engineers

Project Engineer: Project engineers have to accomplish all the paperwork, process the orders, and take care of the day-to-day operation of the site. They get in touch with all supervisors to overcome the issues before they spread.

These engineers set up timelines for supervisors to abide by. Project engineers have to supervise and coordinate with site engineers on the technical properties of the project. These professionals are accountable for status and budget reports together with personnel assignments.

Given below, the liabilities of a project:

• Evaluating of all plans and proposals prior to meet with management
• Scrutinizing bids for new projects
• Evaluating and examining of all drafts and blueprints
• Arrangement of cost estimates for materials, equipment and labor

Common types of walls found in construction

The following types of walls are generally found in building construction.

Types of Walls:
Load Bearing Walls - Precast Concrete Wall, Retaining Wall, Masonry Wall, Pre Panelized Load Bearing Metal Stud Walls, Engineering Brick Wall, Stone Wall

Non-Load Bearing Wall - Hollow Concrete Block, Facade Bricks, Hollow Bricks, Brick Walls, Cavity Walls, Shear Walls, Partition Walls, Panel Walls, Veneered Walls, Faced Walls.

Given below, the details of these walls.

Load Bearing Walls: Load bearing wall belongs to a structural component. It bears the weight of a house from the roof and upper floors and transmits the weight to the foundation. It provides support to the structural members like beams, slab and walls situated over floors. A wall that is situated directly over the beam is known as load bearing wall. The purpose of load bearing wall is to bear the vertical load. On contrary, if a wall doesn’t contain any walls, posts or other supports directly over it, it is prone to be a load-bearing wall.

Load bearing walls also bear their self weight. This wall is normally situated over one another on each floor. Load bearing walls are utilized as interior or exterior wall. This type of wall will often be perpendicular to floor joists or ridge. Concrete is a useful material to support these loads. The beams enter directly into the concrete foundation. Load bearing walls inside the house is likely to run the equivalent direction as the ridge.

Various types of load bearing walls:
Precast Concrete Wall, Retaining Wall, Masonry Wall, Pre Panelized Load Bearing Metal Stud Walls, Engineering Brick Wall, Stone Wall.

Non-Load Bearing Walls: Non-load bearing wall means a wall that doesn’t allow the structure to stand up and retain itself. It doesn’t deal with floor roof loads over. It is a framed structure. Normally, these belong to interior walls whose purpose is to separate the structure into rooms. They are constructed lighter.

The non-load bearing walls can be eliminated devoid of risking the safety of the building. Non-load bearing walls are recognized with the joists and rafters. They are not intended for gravitational support for the property. This type of wall is inexpensive. This wall is also known as “curtain wall”.

Types of Non-Load Bearing Wall:
Hollow Concrete Block, Facade Bricks, Hollow Bricks, Brick Walls

Cavity Walls: The cavity wall comprises of two individual withes which are formed with masonry. These two walls are called as internal leaf and external leaf. This wall is also called as a hollow wall. The purpose of these walls is to minimize their weights on the foundation. The walls function as good as sound insulation. Cavity wall offers superior thermal insulation as compared to any other solid wall since the space is completely filled with air and lessens heat circulation. They contain a heat flow rate that is 50 percent that of a solid wall. It is very cost-effective as compared to other solid walls. It has good fire resistance capacity. Cavity wall facilitates to get rid of noise.

Shear Walls: It stands for a framed wall. The prime objective of the wall is to withstand lateral forces which generate from the exterior walls, floor, and roofs to ground foundation. The shear wall is effective for large and high-rise buildings. The main ingredients of this wall are concrete or masonry. It contains a sound structural system to withstand earthquake. It offers stiffness in the direction. The construction and application are easy in shear walls. It is situated uniformly to minimize adverse effects of a twist.

Partition Walls: It is suitable for segregating spaces from buildings. The wall is hard and made of brick or stone. It is a framed construction. The partition wall is attached with the floor, ceiling, and walls. It has good strength to bear its own load. It defends against impact. It is durable and strong to support wall fixtures. Partition wall functions as a sound barrier and it has good resistance capacity against fire.

Panel Walls: It is a non-bearing wall among columns or pillars that are supported. The panel is set up with both nails and adhesive. The paneling design choices comprise of rustic, boards, frame. Paneling is done with hardwoods or inexpensive pine. Prior to set up panel walls, the space should be painted.

Veneered Walls: The material is retained through a veneered wall. The brick or stone are main ingredients of the veneered walls. The wall is only one wythe thick. It became the norm when insulation is necessary in the interior walls for building codes. It is light weighted. Less time is required for building up the veneered walls.

Faced Walls: It is a wall where masonry facing and backing are attached to make use of common action under load. The installation process is very simple.

Some useful tips on concreting in hot weather

The quality of concrete is affected by severe weather conditions (intense heat or cold, and humidity deviations). If concreting is done in hot weather, proper precautions should be taken to combat all the adverse effects of extreme ambient temperature.

Definition of hot weather for concreting: As per guidelines provided by American Concrete Institute (ACI) vide ACI-305R-10, hot weather means job-site conditions that speed up the rate of moisture loss or rate of cement hydration of freshly mixed concrete, along with the following:

a) Ambient temperature of 27 °C (80°F) or greater; and
b) Evaporation rate that surpasses 1 kg/m2/h

Canadian Concrete Design code (CSA A23.1/.2) employs the similar ambient temperature for hot weather (27 °C).

Challenges of Hot Weather Concreting

How concrete is impacted with hot weather: The water is a prime ingredient in concrete. When the temperature is raised, the rate of vaporization is also increased. So, adequate quantity of water is required in concrete production to cope up with hot weather condition.

The following issues are also occurred due to hot weather condition:

1- Accelerated slump loss leading to the addition of water on the job-site,
2- Increased rate of Setting resulting in placing and finishing difficulties,
3- Increased tendency for thermal and plastic cracking,
4- Critical need for prompt early curing,
5- Difficulties in controlling entrained air,
6- Increased concrete temperature resulting in long term strength loss.

Precautions for Hot Weather Concreting: These precautions should be taken throughout concrete production and delivery, and will enhance the stability performance of concrete to get rid of unwanted cracking.

1- Apply materials and mix proportions which contain good resistance capacity against hot-weather conditions.
2- Chill the concrete or one or more of its constituents.
3- The uniformity of concrete should allow quick placement and consolidation.
4- Minimize the time of transport, placing and finishing as far as possible.
5- Schedule concrete placements to control exposure to atmospheric conditions (i.e. at night or all through good weather conditions).

Common Solutions for Cooling Materials: The common process to be followed for chilling concrete is to reduce the temperature of the concrete materials prior to start of mixing.

The aggregates and mixing water should be retained as cool as possible since these materials significantly affect the concrete temperature after mixing as compared to other materials. In severe hot condition, a segment of water is substituted with ice to reduce the temperature. Curing of concrete is vital for decreasing the adverse effects of hot weather on the quality of concrete.
