FAQ

Frequently Asked Questions

What is an engineering survey?

An engineering survey is a specialized type of surveying that provides precise measurements and data for construction and infrastructure projects. It includes setting out works to design specifications, establishing control networks, monitoring structural movements, and verifying as-built conditions against design drawings.

What is construction setting out?

Construction setting out is the process of transferring design coordinates from plans to the actual construction site. It marks the exact positions of buildings, foundations, walls, columns, roads, and other structural elements according to the engineering drawings, ensuring the project is built precisely as designed.

How accurate are engineering surveys?

Engineering surveys achieve millimeter-level accuracy using precision instruments like robotic total stations and GNSS RTK receivers. For control networks, we typically achieve ±2mm horizontal and ±5mm vertical accuracy. As-built surveys typically achieve ±5-10mm accuracy depending on conditions.

What equipment is used for engineering surveys?

We use state-of-the-art equipment including Leica robotic total stations, GNSS RTK receivers, digital levels, 3D laser scanners, and specialized survey software. Our equipment is regularly calibrated to maintain accuracy and meets international standards for engineering surveying.

Do you provide as-built surveys?

Yes, we provide comprehensive as-built surveys that document the actual constructed conditions of a project. As-built surveys compare the built structure to the original design, identify any deviations, and provide accurate records for future maintenance and development.

What is a control survey?

A control survey establishes a network of precisely measured reference points across a construction site. These points serve as the foundation for all subsequent survey work, ensuring consistency and accuracy throughout the construction process. We establish both horizontal and vertical control networks.

How much do engineering surveys cost in Zanzibar?

Engineering survey costs in Zanzibar depend on the type of survey, project size, complexity, and duration. Basic setting out services start from competitive rates. Contact us for a free, no-obligation quote tailored to your specific project requirements.

What industries do you serve?

We serve a wide range of industries including residential construction, commercial development, hospitality and tourism, infrastructure and roads, marine and port facilities, industrial and manufacturing, and government and public works projects across Zanzibar and East Africa.

Do you offer structural monitoring services?

Yes, we provide structural monitoring and deformation surveys for buildings, bridges, dams, and other structures. Using precision instruments and automated monitoring systems, we detect and measure any movements or settlement, ensuring structural integrity and safety.

Can you handle large infrastructure projects?

Absolutely. We have extensive experience with large-scale infrastructure projects including roads, bridges, ports, airports, and utilities. Our team can manage complex survey requirements across multiple phases of construction, providing continuous support from planning through completion.
