Construction Supervision Services
Construction Supervision Services by TUV Austria Bureau of Inspection & Certification ensure that your construction project runs smoothly and fulfills all quality & regulatory requirements.
Why Do You Need Construction Supervision Services?
Construction Supervision Services help you complete your project on time and within budget while meeting all relevant regulations and quality standards. Whether you are involved in constructing buildings, infrastructure, industrial plants, wind farms, or power facilities, your projects involve the complex coordination of different contractors.
What are the 12 Steps of Construction Supervision Services?
Once the construction drawings and other related documents have been completed and approved by the authority in the jurisdiction, the project will be awarded to a contractor by the client through a consultant. In this period, the Construction of the proposed project will begin. The Construction can be summarized into 12 stages.
1). Clearing of the Ground
To begin the actual construction, the Clearing of the Ground from where the project’s location will have been built is the first thing to consider. Next, the construction personnel’s task is to free the construction site from any obstruction and debris that may obstruct and delay the construction.
The temporary facilities such as the Engineers’ office, labors quarter, material storage room, quick water, electric supplies, and other related facilities should also be constructed before starting the work. A site perimeter fence should also be built during this period.
2). Site Layout and Stalking
This activity involves setting the reference points as construction grid lines and marking off the gate level. This is performed to ensure that the grids have been set up on-site according to approved plans. The reference plan should be appropriately marked and not disturbed throughout the construction. Gridline, according to the approved drawing, should be layout before construction.
Depending on the complexity and size of the project, the construction grids can be laid out through theodolite or related surveying instruments. A more traditional way of the construction grid form is popular for small projects through stalking using batter board and strings. Batter boards are temporary wooden frames used to suspend the strings. According to approved plans, the strings represent the grid lines in X and Y directions.
These will guide the construction, so it is essential to fix a reference line in both directions to be used once the grids have been placed when needed in the building.
Once the layouts of construction points and grid lines have been completed, the excavation works begin. The excavation depth depends on the recommendation of the soil investigation report. But it is safe to say that the minimum excavation level for the footing to rest should stick to 1 meter below the gate level or the 0.00 level.
Excavation works is a massive activity; therefore, proper caution should be observed during this stage. Shoring support is recommended if the excavation and the neighbor’s existing structure exceed 1.20 meters from your proposed level are needed.
4). Compacting & Laying of PCC
Compacting the excavated surface should perform once we reach the desired excavation level. A layer of crushed gravel is then to be added during the compacting. In a standard compaction procedure, the final compacted layer should be checked to get the desired degree of compaction to not less than 95% of the maximum dry density. An anti-termite treatment on the ground should also be considered in this stage.
The laying of PCC or Plain Concrete Cement should follow afterward in preparation for rebar works. PPC is usually composed of 10 mm thick lean concrete for the footing rebar to be laid evenly leveled.
5). Foundation and Rebar Column Starter Bars
Once the laying of PCC has been set up, their bar works for the foundation, and any foundation beams are the next activity. In this stage, the reinforcement of the foundations is being prepared according to the structural schedule and its formworks.
The proper and standard concrete cover should be observed during this procedure. Starter bars for columns should also be installed accordingly before concrete pouring.
6). Concerting of Foundations
Concerting of Foundations and Column Rebar Installation Concerting of foundations has to come next after the rebar works. The concrete to be poured should be appropriately vibrated, especially the aggregates, to spread into the footing fully. Installation of column reinforcement on the previously installed column starter bars should be continued.
A proper concrete cover should consider before closing the form works. For substructure columns, an additional concrete cover of at least 50mm has to be considered up to plinth level to protect the rebar from possible corrosion due to sulfate attack.
7). Concerting of Column & Bitumen Paint Applications
Once the concerting of stub columns has been completed, give time for the concrete to dry completely and apply at least two coats of bitumen paint for both footing and stub columns. Bitumen paint helps absorb moisture due to the soil preventing seepage into the substructure concrete.
8). Setting Up Perimeter Blocks
Install solid blocks along the perimeter or the edge of the proposed project. This establishes a boundary between the inside and outside edges of the project. It is also helpful when the difference between inside floor finish level and outdoor pavement or ground level is significant. Two coats of Bitumen paints should also apply afterward. In some cases, perimeter blocks are optional, especially for areas with too firm soil characteristics.
9). Backfilling and Compacting
Once the substructures like foundation structures, including the solid blocks, have been installed, backfilling and compacting should occur. Backfilling and compacting should be partially done to ensure that the required degree of crowding has been met until the bottom of the tie-beam level is reached.
10). Tie Beam Reinforcement, Grade Slab, and Concreting
Preparation and Installing the tie-beam reinforcement as per the approved drawing is the next step to consider after the backfilling and compacting. Formworks with standard concrete cover are also included in this stage. once the reinforcement works have been completed, we can start the concreting. Installing of grade slab mesh and concrete work is then to be followed.
11). Rebar Works and Concreting of Columns
At this stage, the substructure component of our project has been completed. It is now time for the project to go up. The next thing to consider is the rebar works, shuttering or formworks, and concreting to be done. Before concreting, we see that the columns followed the structural schedule, the formworks should be vertically level, and a standard concrete cover has to be maintained before the closing of forms.
12). Beam and Slab Works
Once the ground floor columns have been cast, it is time to prepare the beams and suspended slab reinforcement activity. Like any other structural member, beams and slab reinforcement should be followed strictly. Shuttering or formworks for lab and beams should be adequately anchored and checked before concrete pouring. Step 11 can be repeated accordingly until the structural frame or the core and shell of the structure have been completed.
