Industrial Surveying
El-Eman Office provides surveying and contracting services for industrial projects across all industrial zones in Egypt.
The factory survey network: horizontal and vertical control
In industrial project surveying, a network of fixed control points is usually established inside the site and used throughout construction. These points are protected by barriers or placed away from machinery traffic, and are checked periodically because excavation and heavy equipment can shift them. The designer sets the main axes of the building and machinery, and all work is transferred from them to keep everything consistent.
Precise setting out of foundations and machines
Some industrial equipment needs higher accuracy than ordinary building work, such as production lines, bearings and heavy machine bases. Key points include:
- Setting out foundation axes and anchor bolts accurately before the pour, because adjusting them after the concrete hardens is difficult.
- Controlling the levels of foundation tops and production floors against a single reference level.
- Checking the flatness of industrial floors and that they are free of undulations, especially where cranes and forklifts operate.
- Setting out overhead crane runways and the columns that carry them to the tight tolerances specified by the supplier.
Utilities, construction monitoring and handover
Factories contain intertwined networks of pipes, cables and drains, and their locations and levels should be documented before backfilling, because reaching them later is expensive. Photographs and coordinates of each joint before covering, then included in the handover drawings, are very useful.
During construction, column verticality, steel frame deviation and the consistency of heights are monitored, and the dimensions are checked again before each stage is accepted. At the end, as-built drawings are prepared showing buildings, internal roads, utility lines and site boundaries, an important reference for maintenance and future expansion.
Future expansion and planning the industrial plot
Factories usually grow after they start operating, so it helps to reserve part of the land for expansion and not to place buildings in a way that blocks extensions. A good survey helps compare layout options before fixing them: locations of stores, workshops and administration, truck and crane movement, loading and unloading areas, and fire and emergency routes. The natural ground level also affects earthworks quantities and how rainwater drains away from buildings, since pooling water damages floors and stock in factories.
It is advisable to prepare the drawings in an organised digital format with clear layers for buildings, roads and utilities, so new phases can be added and merged with the existing plan without a full resurvey.
Frequently asked questions
Why is surveying before the start of work not enough?
Because a project runs over time, points move and conditions change, so checks and follow-up are needed at each critical stage.
What most often causes problems when installing machines?
Different references between work teams, anchor bolts shifting during the pour, and not verifying the final foundation levels before the equipment arrives.
Does land intended for a factory need a survey before design?
Yes. A topographic survey shows the ground slopes, earthworks quantities, boundaries and existing utility lines, which are essential design inputs.
