Structural & Steel Detailing Services in Pakistan

You have a structural engineer’s design. You have ETABS calculations. But your contractor in Lahore or steel fabricator in Karachi cannot build from analysis reports. They need detailed shop drawings. They need bar bending schedules that show exactly how to cut and bend each steel bar. Consequently, without proper structural & steel detailing services in Pakistan, your project faces rebar waste, fabrication errors, and costly delays. At Ahmed Construction Company (ACCO), we bridge the gap between engineering design and site construction. For over 25 years, we have provided detailing for Meezan Bank, Bata, BUITMS, Savour Foods, and Gerry DNATA. Specifically, from home floor plan reinforcement to complex steel structures for textile mills, our detailing is accurate, fabrication-ready, and PEC-certified.

What Are Structural & Steel Detailing Services?

Structural detailing is the process of creating detailed shop drawings for reinforced concrete (RC) structures—foundations, columns, beams, slabs, and stairs. This includes bar bending schedules (BBS) that specify bar diameter, shape, length, and quantity. Similarly, steel detailing focuses on steel structures—columns, beams, bracing, connections, and crane girders—including bolt schedules, weld specifications, and fabrication dimensions.

In Pakistan, proper detailing is mandatory for PEC approval and for bank financing (e.g., Meezan Bank requires detailed BBS for construction loans). Unfortunately, many engineers skip detailing to save costs—resulting in steel waste, incorrect bar placement, and failed inspections. Therefore, ACCO’s structural & steel detailing services in Pakistan comply with ACI (concrete) and AISC/AWS (steel) standards. We serve residential clients needing a home floor plan with complete BBS, commercial developers requiring fast erection, and industrial clients who need fabrication-ready steel models. Our coverage includes DHA, Bahria Town, Wapda Town, Lake City, Model Town, Johar Town, Askari Housing, and nationwide Pakistan.

Our Structural & Steel Detailing Services – Detailed Breakdown

We provide complete detailing for both concrete and steel structures. However, to ensure clarity, we have broken down our offerings into specific sub-categories below.

1. Concrete Reinforcement Detailing (Bar Bending Schedules)

We produce detailed bar bending schedules (BBS) for all concrete elements: foundations (spread, raft, pile caps), columns (with lap locations and tie spacing), beams (top and bottom reinforcement, stirrups), slabs (bottom mesh, top mesh), stairs, and retaining walls. Moreover, our BBS includes bar mark, shape code (BS 8666), diameter, length, quantity, and bending dimensions. Consequently, contractors can order steel accurately—reducing waste by 10-15%.

2. Steel Structure Detailing (Tekla & AutoCAD)

For pre-engineered buildings, warehouses, factories, and textile mills, we produce detailed steel shop drawings. Specifically, this includes column base plates, beam-to-column connections, rafter splices, bracing connections, crane girders, and purlin layouts. We use Tekla Structures for 3D modeling and generate NC files for automated cutting. Therefore, steel fabricators in Lahore, Karachi, and Faisalabad prefer our drawings because they are fabrication-ready.

3. Precast Concrete Detailing

For projects using precast elements (wall panels, hollow-core slabs, beams), we produce detailing including embedded plates, lifting inserts, connection details, and grouting specifications. In addition, we have detailed precast structures for industrial warehouses and parking garages.

4. Connection Design & Detailing

Connections are the most critical part of any steel structure. Thus, we detail moment connections, shear connections, pinned connections, and base plate connections. Furthermore, we specify bolt grades (A325, A490), weld symbols (AWS A2.4), and fit-up tolerances.

5. Shop Drawing Production

We produce complete shop drawing sets including general arrangement (GA) drawings, single-part drawings, assembly drawings, and erection drawings. Similarly, for concrete, we produce formwork drawings and reinforcement placement drawings. All drawings include material lists, cutting lists, and weight calculations.

6. 3D Tekla Models & BIM Integration

We deliver full 3D Tekla models for steel structures and Revit models for concrete. Additionally, we export IFC files for BIM coordination with architectural and MEP models. We also provide BIM Modeling clash detection. Explore our Modular BIM Modeling page for more.

7. Quantity Takeoff & Material Estimation

From our models and drawings, we extract concrete volume, reinforcement weight, steel tonnage, and formwork area. As a result, contractors use these quantities for procurement and budgeting. Accuracy is typically within 1-2% of final site usage.

Comparison: ACCO vs. Typical Detailing Providers

Many small shops offer “detailing” but lack structural understanding. Consequently, here is why ACCO is different:

Our Step-by-Step Detailing Process

We turn your structural design into fabrication-ready shop drawings. Specifically, here is our 7-step workflow:

1. Step 1: Receive Design Inputs – You share your structural design (ETABS/STAAD outputs). We accept PDF, DWG, or hand sketches.
2. Step 2: Detailing Setup & Standards Selection – We confirm detailing standards: ACI (concrete), AISC (steel), AWS (welding).
3. Step 3: Concrete Reinforcement Detailing (BBS) – For concrete structures, we detail foundations, columns, beams, and slabs. Furthermore, we produce bar bending schedules.
4. Step 4: Steel Structure Detailing (Tekla Modeling) – For steel structures, we create a 3D Tekla model and run clash detection.
5. Step 5: Shop Drawing Production – We produce single-part drawings, assembly drawings, and erection drawings.
6. Step 6: Engineering Review & Quality Check – A PEC-registered engineer reviews all details for accuracy. Consequently, we ensure constructability.
7. Step 7: Delivery & Revisions – We deliver shop drawings in PDF/DWG and Tekla models. We include 2 rounds of revisions.

Why Pakistani Fabricators & Contractors Choose ACCO for Detailing

Pakistan’s steel fabrication industry faces a common problem: poor-quality shop drawings. As a result, many contractors hand over vague sketches to fabricators, resulting in wrong member sizes and rework. Similarly, for concrete structures, missing bar bending schedules lead to steel waste—5-10% rebar is typically thrown away.

Therefore, ACCO has provided structural & steel detailing services in Pakistan for over 500 projects. We have detailed Meezan Bank branches (vault reinforcement), Savour Foods (industrial kitchens), and textile mills (large-span steel frames). Furthermore, our team coordinates with architectural engineering to ensure details align with finishes. Explore our Architectural Engineering page for integration details.

We also support international projects. Specifically, for clients in UAE, UK, Saudi, Canada, and USA, we deliver detailing that meets AISC and AWS standards.

Frequently Asked Questions (FAQs) – Structural & Steel Detailing

1. What is the difference between structural detailing and structural design?

Structural design determines member sizes and reinforcement amounts. In contrast, structural detailing produces the actual shop drawings that fabricators use to build—bar bending schedules and connection details. Both are essential.

2. Do I need steel detailing for a simple home floor plan?

For a residential home floor plan with concrete construction, you need concrete reinforcement detailing (BBS). However, steel detailing is only needed if your home uses steel beams. Visit our Home Floor Plan Design page.

3. What is architectural engineering, and how does it relate to detailing?

Architectural engineering integrates structural, MEP, and architectural systems. Consequently, our detailing accounts for MEP openings and architectural finishes. Learn more on our Architectural Engineering page.

4. Do you provide 3D walkthroughs of detailed models?

Yes. We provide 3D architectural walkthrough of our Tekla and Revit models. See our Architectural 3D Modeling page for examples.

5. Can ACCO detail structural steel for commercial plazas and hospitals?

Absolutely. We have detailed steel for commercial plazas and hospitals. View our portfolio on the Our Projects page.

6. What is a bar bending schedule (BBS) and why is it important?

A BBS is a table listing every steel bar required. Without a BBS, steel waste is 5-10%. With a good BBS, waste is under 2%. ACCO includes detailed BBS in all our concrete detailing packages.

7. Do you provide Tekla models for steel fabrication?

Yes. We provide full 3D Tekla models plus NC files in DSTV format for CNC machines. This reduces fabrication errors by 30-40%.
