Integrated Detailed Engineering 

We develop detailed process engineering that translates flowsheet intent into coordinated unit operation requirements and tender-ready equipment specifications. This includes confirming process design criteria, validating mass and water balances, developing process flow diagrams, sizing key equipment, preparing process data sheets and integrating piping and instrumentation diagram inputs within the wider engineering package. Our teams connect testwork outcomes, unit operation selection, operating cases, turndown requirements, control philosophy inputs, layout, risk controls and downstream performance requirements so the plant design is practical, operable and ready for procurement and delivery. 

We support process safety and risk management through structured safety-in-design and risk review processes that help identify, assess and control hazards as the design develops. This can include Safety in Design reviews, such as HAZOP, CHAZOP, RAMBO (reliability, availability, maintainability, buildability, operability) reviews, hazardous area classification, functional safety inputs, SIL assessments. Our teams connect these reviews with design criteria, control philosophy, safety requirements, operability, maintainability and action close-out so risk controls are embedded into the engineering package. 

We deliver coordinated structural, mechanical and piping engineering for process plants, materials handling systems and associated infrastructure. Our teams integrate 3D plant models, general arrangements, structural steel and concrete design, equipment support structures, access platforms, mechanical equipment specifications, piping layouts, pipe supports and vendor package interfaces. This helps align equipment integration, piping routes, maintenance access, lifting requirements, fabrication, installation, constructability and long-term operating reliability within the wider engineering package. 

We support robust bulk materials handling design across transfer, chute, conveying, stockpiling, reclaim, stacker, reclaimer and loadout interfaces. Our teams consider material characteristics, conveyor loading, transfer performance, dust, spillage, wear, blockage and maintenance access requirements as part of the wider plant design. Where appropriate, discrete element method (DEM) analysis can inform transfer and chute design by modelling material flow, trajectory, impact zones, hang-up risk and wear patterns, helping improve reliability, operability and maintainability across the materials handling system. 

We provide civil engineering design that supports practical plant and infrastructure development, including site layout interfaces, bulk earthworks, grading, roads, access, laydown areas, hardstands, drainage, concrete foundations and equipment support interfaces. Our teams consider geotechnical inputs, stormwater management, clean and dirty water separation, erosion and sediment controls, underground services, construction staging and site-specific conditions such as terrain, rainfall and flood risk. This helps align civil works with plant layout, constructability, environmental requirements and long-term operational performance. 

We deliver electrical design engineering, instrumentation, control systems engineering, and automation inputs that support safe, reliable and effective plant control. Our teams integrate power distribution, MCC / E-House, earthing, lighting, field instrumentation, control system architecture, industrial networks, cybersecurity requirements and operational visibility with the wider plant design. This includes developing single line diagrams, load lists, instrument indexes, I/O schedules, control philosophies, functional descriptions and commissioning support documentation. We also engineer power system studies, protection coordination, hazardous area inputs, functional safety requirements, PLC / SCADA / DCS interfaces, historian integration and remote operations or reporting requirements, helping clients create systems that are practical to commission, maintain and operate.   

We incorporate tailings, water, emissions and environmental engineering considerations into detailed design so projects can better manage process water, tailings handling, emissions interfaces, environmental controls and sustainability-related design requirements as part of the overall engineering solution. Our teams bring deep experience in tailings dewatering equipment and tailings handling integration, including thickening, filtration, pumping, water recovery, filtrate return, underflow management and downstream storage or dry stack interfaces. Sedgman’s integrated approach helps build environmental controls into the engineering packages. 

Sedgman uses integrated engineering, design and project management systems to support the rigour, coordination and control required for complex multidisciplinary projects. Our drafting and modelling systems support coordinated model development, drawing production and design data management across disciplines. Sedgman uses established design and drafting platforms, including Autodesk and Bentley software, alongside discipline-specific tools and common data environment workflows to develop 2D drawings, 3D models, plant layouts, piping arrangements, civil and structural details, electrical and instrumentation deliverables and vendor package interfaces. Our systems help teams manage discipline interfaces, technical reviews, design data, document control, project schedules, cost information and quality assurance to produce quality-assured engineering deliverables that support procurement, construction, commissioning and long-term asset information requirements. 

We bring discipline interfaces together through structured reviews, technical specification development, vendor information integration, QA/QC processes and constructability, operability and maintainability thinking. This provides clear reliable packages for procurement, construction, commissioning and operations.
