Structural Design For Multistorey Buildings
Safe, economical and code-compliant structural design for residential, commercial, institutional and mixed-use multistorey buildings — from concept to Good-for-Construction drawings and construction-stage support.
What we do
TeXeL acts as Principal Structural Consultant for multistorey buildings — residential towers, apartments, commercial complexes, hospitals, hostels, hotels, institutional blocks and mixed-use developments. We take a project from the first architectural concept to Good-for-Construction (GFC) drawings and stay with it through construction, so that the structure is safe, serviceable, durable and economical while respecting the architect's intent and the owner's budget.
Our team works on RCC, steel and composite systems, including basements, podiums, transfer levels, shear-wall and flat-slab systems, and tall buildings in high seismic and wind zones. Every design is prepared to the applicable Indian Standards (IS 456, IS 875, IS 1893, IS 13920, IS 800) and the National Building Code, with international codes adopted where a project demands them.
Why hire TeXeL
- Experience that shows on site — 1300+ projects delivered since 2011, including 20-storey towers, hospitals and campuses, guided by a mentor with four decades in structural behaviour and evaluation.
- Design that saves money — structural optimisation of member sizes, foundation schemes and reinforcement typically reduces material quantities without compromising safety.
- Code compliance, documented — a Design Basis Report records loads, philosophy and code clauses, so approvals and third-party vetting (IIT/NIT) go smoothly.
- Coordinated, clash-free drawings — BIM-based workflows and close coordination with architects and MEP consultants mean fewer surprises during construction.
- Accountable, single point of contact — a dedicated structural consultant and defined stage-wise timelines for every project.
Our approach — five stages
- Conceptual structural design — evaluate feasible structural systems, study load paths and stability, and position key elements (columns, cores, shear walls) in coordination with the architecture.
- Schematic structural design — build the structural model, fix preliminary member sizes, validate the system against engineering principles and code requirements, and confirm element locations with all disciplines.
- Detailed analysis & design development — advanced computational analysis (gravity, seismic, wind, soil-structure interaction), optimisation for performance and material efficiency, and the Design Basis Report (DBR).
- Good-for-Construction drawings — foundation system, substructure and superstructure drawings with complete reinforcement/steel detailing, schedules and bar-bending details.
- Construction support — quantity take-offs for procurement, periodic site engineering audits to confirm execution matches design intent, and technical assistance for third-party vetting.
Scope of work
- Structural system selection and feasibility studies
- Gravity, seismic (IS 1893) and wind (IS 875 Part 3) analysis; soil-structure interaction
- Foundation design — isolated/combined footings, rafts, piles and basement retaining walls
- RCC and steel superstructure design — columns, beams, slabs, shear walls, cores, staircases, water tanks
- Transfer girders, podiums, cantilevers and special structural elements
- Serviceability checks — deflection, cracking, vibration and durability
- Design Basis Report and design calculations for approvals and vetting
- Coordination with architectural, MEP and façade consultants
Deliverables
- Structural concept and schematic layouts
- Design Basis Report (DBR) and analysis/design calculations
- General arrangement drawings for all levels
- Good-for-Construction drawings: foundation, substructure and superstructure, with reinforcement detailing, bar-bending schedules and steel fabrication details where applicable

Structural Design For Industrial Project
Complete structural design for industrial plants — PEB and conventional sheds, machine and equipment foundations, heavy-duty floors, pipe racks, tanks, solar structures and plant storm-water — delivered by one in-house multidisciplinary team that coordinates in real time with equipment suppliers and keeps pace with the project.
What we do
An industrial project is never one structure. A plant brings together production sheds, machine foundations, heavy-duty floors, pipe racks and cable trestles, silos and tanks, utility buildings, solar rooftops and the storm-water system that drains the whole site — and all of them must work around equipment whose details keep changing until the day it is installed. TeXeL's industrial practice is built for exactly this: an in-house, multidisciplinary structural team that handles every dimension of the plant under one roof and coordinates with your process, equipment and MEP partners as the design evolves.
We have served as principal structural consultant for MDF and wood-panel plants, textile process houses, garment and engineering factories, warehouses and logistics hubs, and have designed large-span sheds for groups such as Sangam India, RSWM and Samarpan Industries. Our approach is practical: designs that match the materials, fabricators and site crews actually available, released in the sequence the construction programme needs.
Why hire TeXeL
- One team for every dimension — steel sheds, RCC structures, machine foundations, floors, solar structures and site drainage are designed by the same in-house group, so interfaces are resolved in the office, not on site.
- Real-time coordination with suppliers — equipment loads, anchor-bolt layouts and cut-outs are updated as vendor drawings change; we track every revision and reflect it in the structural design without delaying the programme.
- Timely, stage-wise release — foundations first, then columns and sheds, then floors and racks, matching your erection and machine-delivery schedule.
- Practical, buildable designs — sections and details chosen for local fabrication capacity, standard rolled sections, available formwork and realistic tolerances.
- Experience across industries — MDF/wood panel, textiles, garments, engineering, food, warehousing and logistics, including Rs 100–200 crore process houses as principal consultant.
- Vetting-ready documentation — Design Basis Report, calculations and drawings prepared for lender, insurer and IIT/NIT scrutiny.
Our approach
- Plant understanding — study of the process flow, equipment list, plant layout and expansion plans; collection of vendor load data and site/geotechnical inputs; identification of critical interfaces.
- Structural concept — PEB versus conventional steel versus RCC, span and bay arrangement, crane and mezzanine provisions, foundation system and floor system options with cost and time comparison.
- Detailed analysis & design — static, dynamic and fatigue analysis as required for cranes, vibrating machinery and wind-sensitive structures; design to IS 800, IS 456, IS 875, IS 1893, IS 2974 and IS 2911; Design Basis Report.
- Supplier coordination loop — anchor-bolt and pocket drawings issued early for vendor confirmation; vendor changes logged and incorporated through controlled revisions.
- Good-for-Construction drawings & site support — GFC drawings with bar-bending schedules and steel quantities, fabrication-drawing review, site clarifications and critical-stage inspections through commissioning.
Scope of work
- Industrial sheds & buildings — PEB and conventional steel sheds, large-span portal frames, trusses, crane girders, mezzanines, utility and administrative buildings
- Machine & equipment foundations — block, framed and vibration-isolated foundations for presses, compressors, turbines, mills, dryers, generators and process lines (IS 2974)
- Heavy-duty floors — jointed and jointless industrial floors for forklifts, racking and stacked loads; trenches, pits and tunnels
- Pipe racks, trestles & platforms — pipe and cable racks, equipment supporting structures, access platforms, chimneys and stacks
- Tanks, silos & bunkers — RCC and steel storage structures, ETP/STP tanks, fire-water tanks
- Solar structures — rooftop and ground-mounted module mounting structures, with roof-capacity checks for existing sheds
- Site infrastructure — plant storm-water drainage, retaining walls, roads and hardstands, compound walls, weighbridge foundations
- Expansions & retrofits — strengthening of existing sheds and foundations for new machinery or added loads
Deliverables

Structural Design For Infrastructure Projects
Structural design for public infrastructure — city-wide storm-water systems, STPs and WTPs, water tanks, minor bridges, culverts, drains, foot-over and pedestrian bridges — with rigorous input verification, buildability checks and zero compromise where public money and public safety are involved.
What we do
TeXeL designs the structures that make towns and cities work. Our infrastructure practice covers storm-water management systems for entire towns and cities, sewage and water treatment plants (STPs/WTPs), overhead and ground service reservoirs, minor bridges, slab and box culverts, drains and retaining structures, and foot-over bridges and pedestrian bridges — along with pumping stations, intake works, canal structures and other civil assets for government departments, urban local bodies, PSUs and their contractors.
These assets are built with public funds, serve the public for decades and are often executed by contractors in remote locations. We therefore design them with the same five-stage rigour as our building work, and add three disciplines that infrastructure demands: input data verified with care, a robust assessment of executability before drawings are released, and zero compromise on the public account — no over-design that wastes taxpayer money, no under-design that puts users at risk.
Why hire TeXeL
- City-scale experience — storm-water management systems designed for four towns in Rajasthan; bridge widening and full load tests for bridges and elevated roads in Jaipur; drainage, culvert and treatment-plant structures across India.
- Hydraulic–structural coordination — we design liquid-retaining and drainage structures hand in hand with the hydraulic design, so sections, invert levels, freeboard and joints are consistent.
- Designs that contractors can build — every drawing passes an executability review: construction sequence, dewatering, formwork, access, available materials and local workmanship.
- Government-ready documentation — Design Basis Reports, calculations and drawings prepared to IRC, IS and CPHEEO norms for departmental scrutiny, IIT/NIT vetting and audit.
- Accountability on public money — optimised sections and reinforcement, quantities reconciled to drawings, and clear records for every design decision.
Our approach
- Input verification — survey levels, geotechnical reports, hydraulic/hydrological data, traffic and loading class, water table and site constraints are checked for completeness and consistency before design begins; gaps are flagged in writing.
- Conceptual design — structural system selection (RCC, steel, composite, precast), span arrangement, foundation type and construction methodology options, with a comparative note for the department.
- Detailed analysis & design — analysis for dead, live, vehicular (IRC Class A/70R), hydrostatic, earth, buoyancy, seismic and wind loads; design to IS 3370, IS 456, IS 800, IRC codes and CPHEEO manuals; Design Basis Report.
- Executability assessment — review of construction sequence, dewatering and shoring, joints and water-stops, formwork and reinforcement congestion, and site logistics; design adjusted so it can be built as drawn.
- Good-for-Construction drawings & support — GFC drawings with bar-bending schedules and quantities, followed by site clarifications, inspection of critical stages and assistance for departmental and third-party vetting.
Scope of work
- Storm-water management — city/town-wide drainage networks, box and pipe drains, outfall structures, detention tanks, pumping stations
- Treatment plants — STP and WTP units: aeration tanks, clarifiers, SBR basins, filter houses, sludge beds, chemical houses, pump houses and inter-unit piping supports
- Water retaining structures — overhead service reservoirs, ground reservoirs, sumps and intake wells to IS 3370 (crack-width controlled design)
- Bridges & culverts — minor bridges, slab culverts, box culverts, causeways, approach retaining walls and abutments to IRC codes
- Pedestrian structures — foot-over bridges, pedestrian bridges, skywalks, staircases, lifts/escalator supports and canopies
- Allied works — retaining walls, boundary and compound walls, canal and road structures, utility trenches, service corridors
- Design review — proof checking of infrastructure designs prepared by others; assistance in IIT/NIT vetting
Deliverables
- Input-data verification note and design assumptions register

What we need from you
- Topographic survey and alignment / layout drawings
- Geotechnical investigation report and water-table data
- Hydraulic / hydrological design (or data to prepare it), design flows and capacities
- Loading class, design life and departmental specifications or DPR
- Site constraints — utilities, right-of-way, traffic diversions, access
- A nominated engineer from the department or contractor for coordination
Codes and tools
IS 456, IS 3370 (Parts 1–4), IS 800, IS 875, IS 1893, IS 13920, IRC 5 / 6 / 21 / 78 / 112, CPHEEO manuals on sewerage and water supply, MoRTH specifications and the National Building Code; analysis in STAAD.Pro, ETABS, SAFE and dedicated bridge/tank design tools, with drawings in AutoCAD/Revit.
Key points
- City-wide storm-water systems, STPs/WTPs, water tanks, minor bridges, slab and box culverts, drains, foot-over and pedestrian bridges.
- Input data — survey, soil, hydraulics, loading — verified and recorded before design starts.
- Executability assessed on every drawing: sequence, dewatering, joints, formwork, reinforcement congestion, site logistics.

Structural Design For Steel Structures
Analysis, design and detailing of steel structures — buildings, sheds, towers, high masts, canopies, bridges and platforms — to IS 800 and IS 875, with every connection designed in-house and fabrication-ready drawings, so nothing is left to the fabricator's guess.
What we do
TeXeL designs steel structures end to end — multistorey steel and composite buildings, long-span sheds and hangars, trusses and space frames, high masts, towers and stacks, canopies and skywalks, pedestrian and minor bridges, pipe racks, platforms and staircases. The process mirrors our multistorey building service — concept, schematic, detailed analysis with a Design Basis Report, Good-for-Construction drawings and construction support — but with the extra steps that steel demands: connection design, fabrication-level detailing and erection-stage checks.
In most consultancies the connections — the part of a steel structure that actually fails — are left to the fabricator and never formally designed. At TeXeL every connection is designed and detailed in-house: moment and shear connections, splices, base plates and anchor bolts, bracing gussets, truss nodes and crane-girder brackets, using our own validated connection design sheets. The fabricator receives drawings he can cut, drill and weld from, and the owner receives a structure whose weakest link has been engineered, not assumed.
Why hire TeXeL
- Connections designed, not delegated — complete connection design and detailing with in-house sheets covering bolted, welded, pinned and moment connections to IS 800 and IS 816.
- Fabrication-ready drawings — general arrangement drawings, member schedules, connection details and, where required, fabrication/shop drawings with cut lengths, bolt lists and weld symbols; review of the fabricator's shop drawings when he prepares them.

- Proven on demanding structures — high masts, telecom and transmission towers, large-span industrial sheds, canopies, foot-over bridges and steel-composite buildings designed and proof-checked since 2012.
- Economy through optimisation — section optimisation, rationalised member sizes, standardised connections and minimised site welding reduce tonnage, fabrication time and cost.
- Buildability and erection checks — erection sequence, temporary bracing, lifting points and stability during construction considered at design stage.
Our approach
- Conceptual design — structural system (braced/moment frames, trusses, portals, composite floors, tubular/lattice), span and bay arrangement, material grades and fabrication/erection constraints; comparison of alternatives on tonnage and cost.
- Schematic design — modelling, preliminary member sizing, stability and lateral system check, coordination with architecture, services and equipment.
- Detailed analysis & design — second-order and stability analysis, wind and seismic design, fatigue where relevant (crane girders, bridges, masts), serviceability (deflection, vibration, drift); Design Basis Report.

Structural Design For Facade & Curtain Wall
Structural design of building envelopes — glass curtain walls, aluminium and ACP cladding, CNC-cut and perforated screens, stone, louvres and canopies — using TeXeL's in-house façade design sheets, from wind-load assessment to the smallest bracket, anchor and GFC detail.
What we do
The façade is the most visible part of a modern building and, on a high-rise, one of the most demanding structural systems: it carries wind at the top of the building, follows every movement of the frame, and is built from glass, aluminium and sheet materials that forgive very little. TeXeL provides complete structural design of façades and curtain walls — mullions and transoms, glass and infill panels, brackets, anchors and embeds, sub-frames and secondary steel — so that what the architect has drawn can be engineered, fabricated and installed safely.
We have engineered façades across the full range of systems — stick and unitised glass curtain walls, structural glazing, aluminium and ACP cladding, CNC-cut and perforated metal screens, stone and terracotta cladding, louvres, skylights and canopies — including the façade structural design of DLF Mall, Goa. Every project is taken down to the minor GFC details that façade contractors need: bracket plates, slotted connections, anchor bolts, embed plates, movement joints and sealant gaps.
Why hire TeXeL
- In-house façade design sheets — TeXeL has developed its own validated spreadsheets for every aspect of façade application: wind-pressure zoning to IS 875 Part 3, glass thickness and deflection, mullion/transom sizing, bracket and anchor capacity, thermal and building-movement allowances. They give fast, consistent and auditable results on every job.
- High-rise experience — façades on multistorey residential and commercial towers where wind, inter-storey drift and construction tolerances govern the design.
- Every material covered — glass, aluminium, ACP, CNC and perforated sheets, stone, terracotta, GRC and steel secondary structures, with the right code and manufacturer data for each.
- Detail to the last bracket — GFC drawings and schedules complete enough for fabrication, not just concept sketches.
- Coordination with the main structure — because we also design buildings, we fix embed locations, edge-beam capacities and slab-edge tolerances with the structural engineer early, avoiding costly site fixes.
- Vendor-neutral — we design with the client's chosen system or help compare systems; we are not tied to any façade supplier.
Our approach
- Façade brief & load assessment — architectural intent, system type, building geometry and height; wind-pressure zoning (positive, negative and corner zones), dead loads, maintenance and impact loads, seismic and thermal effects; building-movement criteria from the main structure.
- System design — selection and sizing of mullions, transoms and sub-frames; glass make-up and thickness; panel sizes and support conditions; span-to-deflection checks and serviceability limits.
- Connections & anchorage — bracket design with adjustment and tolerance, anchor bolts and cast-in channels/embeds, interface with slab edges and spandrel beams; design of secondary steel for canopies, screens and feature elements.
- Detailing & GFC — fabrication-level drawings and schedules: typical and special sections, bracket and anchor details, movement joints, parapet, corner, base and head conditions.
- Review & support — review of the contractor's shop drawings and calculations, response to site queries, witness of mock-up/performance tests where required, and sign-off documentation.
Scope of work
- Glass façades — stick and unitised curtain walls, structural glazing (4-side and 2-side SSG), point-fixed/spider glazing, skylights and glass canopies, glass balustrades
- Metal cladding — aluminium and ACP panels, CNC-cut, perforated and expanded-metal screens, louvres, fins and sun-shading devices
- Stone, terracotta & GRC — dry-cladding systems, back frames and anchors
- Secondary structures — steel sub-frames, canopies, feature walls, signage supports, maintenance-unit and BMU restraint points
- Connections — brackets, anchors, embeds, cast-in channels and post-installed anchors with manufacturer-approved capacities
- Checks — wind, dead, live, maintenance and impact loads; deflection and drift accommodation; thermal movement; glass stress and deflection; water-tightness joint widths
- Reviews — independent check of façade contractors' designs; strengthening checks for re-cladding of existing buildings
Deliverables
- Façade design basis — loads, movement criteria, performance requirements and codes
- Wind-pressure zoning drawings for the elevations
- Structural calculations for glass, framing members, brackets and anchors (from TeXeL's in-house sheets)
- Good-for-Construction drawings: elevations, typical and special sections, bracket, anchor and embed details, movement-joint and interface details
- Embed/anchor layout for the main structural contractor
- Shop-drawing review comments, site clarifications and sign-off letter
What we need from you
- Architectural façade drawings and the intended system / material palette
- Structural drawings of the building — slab edges, spandrel beams, columns — and inter-storey drift values
- Building location, height and surroundings for wind assessment
- Preferred glass and system suppliers, if decided, with their technical data
- Maintenance strategy (BMU, cradles) and any performance tests required
- A coordinator from the architect's or façade contractor's team

- TeXeL in-house façade design sheets for wind zoning, glass, framing, brackets and anchors — fast, consistent and auditable.
- GFC detailing down to brackets, anchors, embeds and movement joints — fabrication-ready.
- Early coordination with the main structure: embed layouts, slab-edge capacities and tolerances fixed up front.
- Design and independent review of contractor systems; strengthening checks for re-cladding.
- Design to IS 875, IS 16231, IS 800 and international façade standards; DLF Mall, Goa among completed façades.
Proof Checking and Value Engineering
Independent structural peer review that runs alongside your designer from concept to construction drawings — verifying the design basis, model, calculations and drawings, and identifying value-engineering savings.
What we do
Proof checking is an independent structural peer review that runs alongside the design — from inception to the release of construction drawings. While the project's Structural Engineer of Record develops the design, TeXeL independently examines the design basis, analysis models, calculations and drawings, raises traceable observations and closes them with the design team. Value engineering is built into the same review: wherever the structure can be made more efficient without compromising safety or the architectural intent, we say so, with numbers.
The outcome is a design that has been seen by a second, senior pair of eyes before a single bar is bent — fewer surprises on site, cleaner approvals and a leaner structure. Design responsibility stays with the Engineer of Record; our role is to review, challenge and confirm.
Why hire TeXeL
- Reviewers who design — our peer reviewers are practising structural designers of towers, hospitals, campuses and industrial plants, so observations are practical, not academic.
- Senior oversight — every review is directed by a structural expert with four decades of experience in structural behaviour and evaluation.
- Traceable, closable comments — one consolidated review register with clause references and requested responses, followed by a formal closure review.
- Real savings — value-engineering alternatives for structural systems, member sizes, foundations and reinforcement, quantified so the owner can decide.
- Independent and impartial — we are not the designer and not the contractor; our only interest is a safe, efficient structure.
Our approach
- Inception & information register — register of documents received, information gaps, review priorities and agreed submission sequence (within about a week of appointment).
- Independent review — interrogation of the analysis model, independent checks of critical load paths and elements, and drawing-coordination review against the architectural and geotechnical basis.
- Consolidated review report — observations on design basis, model, calculations and drawings, each with reference, technical note and requested response.
- Response & closure review — review of the design team's responses and revised submission; disposition of every comment.
- Final peer-review report — scope reviewed, material findings, closure status, limitations and any open conditions.
Scope of review
- Design basis and criteria — codes, material grades, design life and durability, loads, combinations and performance criteria
- Structural system and analysis — gravity and lateral systems, load paths, stability, diaphragm action, irregularities, modelling assumptions, seismic and wind inputs, second-order effects
- Foundations and basements — geotechnical parameters, foundation selection, basement slabs and walls, earth and groundwater actions, retention interfaces
- Principal elements — representative and critical RCC, steel, composite or post-tensioned members, transfer zones and discontinuities
- Serviceability and robustness — deflection, drift, crack control, vibration and robustness checks
- Drawings and coordination — consistency of structural drawings with calculations and architecture; major openings, plant loads and key interfaces
- Value engineering — alternatives in system, sizing, foundation scheme and detailing with estimated material savings
Deliverables
- Inception memorandum and information register
- Consolidated structural design review report (review register)
- Comment response and closure register
- Value-engineering note with quantified alternatives
- Final peer-review report
What we need from you
- Coordinated architectural and structural drawings with revision history
- Design Basis Report, analysis models in native/reviewable formats and design calculations
- Geotechnical and groundwater reports; wind/seismic studies where available
- Loading data, specifications and the identity of the Engineer of Record for each submission
- A single point of contact in the design team for comment responses
Typical programme
For a large project the design-stage review takes about eight to ten weeks from receipt of the complete, coordinated structural package: inception within one week, the consolidated review report in five to seven weeks, closure review in two to three weeks and the final report a week after closure. Smaller buildings are reviewed proportionately faster.
How this differs from a design audit
Proof checking is concurrent — it works with the designer while the design is being made. If your drawings are already complete and you need an independent audit and certificate on the finished design, see our Structural Design Audit & Certification service.
Key points
- Independent peer review that runs in parallel with the Engineer of Record — from inception to construction drawings.
- Covers design basis, analysis model, foundations, critical elements, serviceability and drawing coordination.
- One consolidated, traceable review register plus a formal response-and-closure cycle.
- Value engineering quantified: system, sizing, foundation and detailing alternatives with estimated savings.
- Directed by a structural expert with four decades of experience; reviewers are practising designers.
- Design responsibility remains with the Engineer of Record; our comments are independent and advisory.

Independent audit of an already-completed structural design — re-analysis, code-compliance verification of drawings and calculations, graded findings and a certificate of structural adequacy for approvals, lenders and authorities.
What we do
When the structural design of a building is already complete — drawings issued, construction perhaps under way — owners, lenders, authorities and institutions often need an independent confirmation that the design is safe and code-compliant. TeXeL audits the finished design: we re-analyse the structure, check the calculations and drawings against the applicable codes and the geotechnical basis, record every deviation, and issue a structural design audit report and, where the design is found adequate, a certificate of structural adequacy.
Unlike proof checking, which works alongside the designer during design, a design audit is a post-facto examination of what has already been drawn — a single, independent verdict on the design as it stands.
Why hire TeXeL
- Accepted by institutions and authorities — our audit reports and certificates support approvals, IIT/NIT vetting, lender due-diligence and statutory submissions.
- Independent re-analysis, not a paper check — we rebuild the analysis model from the drawings and compare results, so the audit stands on its own numbers.
- Clear verdict — every finding is graded (critical / major / minor / observation) with the code clause and the corrective action required.
- Fast turnaround — a standard building is audited in two to four weeks from receipt of a complete package.
- Senior sign-off — reports are reviewed and signed by a structural expert with four decades of experience.
Our approach
- Document audit — register of drawings, calculations, DBR, soil report and approvals received; identification of gaps.
- Independent re-analysis — structural model built from the issued drawings; gravity, seismic and wind analysis to IS 1893 / IS 875 and the project design basis.
- Design verification — check of foundations, columns, beams, slabs, shear walls, transfer elements and connections against IS 456 / IS 13920 / IS 800 and NBC; serviceability and durability checks.
- Drawing audit — detailing, reinforcement, ductile-detailing provisions and consistency between calculations, drawings and architecture.
- Report & certification — graded findings and corrective actions; on satisfactory closure, a certificate of structural adequacy for the audited design.
Scope of work
- Audit of structural drawings, calculations and Design Basis Report for completed designs
- Independent analysis and design verification of RCC, steel and composite structures
- Foundation adequacy against the geotechnical report
- Code-compliance review — IS 456, IS 875, IS 1893, IS 13920, IS 800, NBC and local bye-laws
- Review of design changes made during construction and their effect on the original design
- Structural design certificate / structural adequacy certificate for approvals, lenders and authorities
Deliverables
- Document register and gap list
- Structural design audit report with graded findings, code references and corrective actions
- Independent analysis summary and verification calculations
- Closure note on corrective actions carried out by the designer
- Certificate of structural adequacy for the audited design (on satisfactory closure)
What we need from you
- Complete set of issued structural drawings (GFC) and architectural drawings
- Structural calculations, analysis files and the Design Basis Report, if available
- Geotechnical investigation report
- Approvals, earlier vetting reports and any revision history
- Purpose of the certificate (authority, lender, institution) so the format meets its requirement

Key points
- Independent, post-facto audit of a completed structural design — drawings, calculations and design basis.
- Design re-analysed from the issued drawings; findings graded with code clause and corrective action.
- Certificate of structural adequacy issued on satisfactory closure — for authorities, lenders and institutions.
- Covers RCC, steel and composite buildings; foundations checked against the soil report.
- Typical turnaround two to four weeks from a complete package.
- Different from proof checking, which reviews alongside the designer during design.
