Eleven services, two departments, one firm.
Civil, structural, survey and geotechnical engineering, tailored to project scale, site conditions and regulatory requirements.

Department 01
Six civil engineering services.
Every one of them is staffed in the Banani office, so the structural, architectural and services drawings agree with each other before they reach site.
01
Structural Design & Engineering
RC and steel structure design for high-rise, industrial, and commercial buildings. Gravity and seismic analysis per BNBC 2020.
02
Architectural Design
Comprehensive architectural design from concept through detailed drawings. Spatial planning, facade design, and building code compliance.
03
Interior Design & Decoration
Complete interior design services for residential, commercial, and hospitality spaces. Material selection, joinery detailing, and execution supervision.
04
MEP Engineering
Electrical, mechanical, and plumbing design. Load calculation, system layout, and coordination with structural and architectural elements.
05
Soil & Foundation Engineering
Geotechnical investigation, soil test interpretation, foundation design and analysis. Shallow and deep foundation solutions for any soil condition.
06
Construction Work
On-site quality control, material testing co-ordination, drawing compliance, and structural certification at project completion.
02 / 02
Department 02 · Five services
Survey & Geotechnical Engineering
Our survey and geotechnical services establish the technical foundation of every project. We evaluate ground conditions, site constraints and development requirements to reduce risk and improve decision-making before construction begins.
Department 02
Five survey and geotechnical services.
The ground is measured and tested before any structural decision is made, so the design starts from the site as it really is.
01
Site Development
Preparing the plot for building: levels, access and site layout, worked out before design begins.
02
Quantity Survey and Geotechnical Measurement
Measured quantities and ground measurements, so cost and design rest on real site figures.
03
Soil & Foundation Investigation
Soil testing and interpretation that tells us whether the building needs a shallow or a deep foundation.
04
Surveying (Contour Line Mapping)
Levels across the site drawn as contour lines, the base drawing for siting and earthwork.
05
Landscaping & Beautification Works
Landscape design for the ground around the building, from planting to hard surfaces.

Deliverables
What arrives at the end of each stage.
Every appointment produces documents you own and can hand to a contractor, a lender or an approving authority.
Stage 01
Written scope
A written response within 24 hours: the disciplines the project needs and what we need from you.
Stage 02
Survey and soil report
Ground conditions, levels and test interpretation, written up before design begins.
Stage 03
Calculations and drawings
Gravity and seismic analysis to BNBC 2020, retained and available on request, with drawings issued for construction.
Stage 04
Structural certification
Issued at completion, once the work built has been checked on site against the drawings issued.
How we engage
Three ways to appoint us.
Every project starts with the same free consultation. What follows depends on how much of the work you want under one roof.
Tier 01
Consultation
Free
- Scope, site and constraints reviewed
- The right disciplines identified
- A written response within 24 hours
- No obligation to continue
Tier 02
Design & Drawings
Fixed fee
- Structural design to BNBC 2020, gravity and seismic
- Architectural drawings from concept to detail
- Soil test interpretation and foundation design
Tier 03
Design + Supervision
Project based
- Everything in Design and Drawings
- On site quality control through construction
- Material testing coordination
- Structural certification at project completion
Before you appoint
Questions about our services
Do I need a soil test before design begins?
Yes. Foundation design depends on ground conditions, so the work starts with geotechnical investigation and soil test interpretation. We then select a shallow or a deep foundation to suit the site rather than assuming one.
How long does a structural design take?
It depends on the floor area, the structural system and the approval route. We confirm a programme after the free consultation, once we have the site information and the architectural brief in front of us.
What happens during construction supervision?
On site quality control, material testing coordination, and checks that the work built matches the drawings issued. At completion we issue structural certification for the project.
Can you take over a project that has already started?
Often, yes. We review the existing drawings and what has already been built, then tell you plainly what can be kept and what has to be redesigned before we accept responsibility for the structure.
What do you need from me to quote?
The site location and plot size, the intended use, the number of floors, any soil report you already hold, and your target start date. Call or email and we will respond within 24 hours.
