The service list below is what you'd hand over. The discipline register underneath is how it gets planned and checked — the same discipline codes your own engineering department already works to.
Routing changes, tie-in point studies, line list updates, and material take-offs for modifications to existing plot plans.
PIPINGEnd-to-end tie-in scopes — hydraulics, isolation philosophy, and construction-ready IFC drawings for connecting new work into a live facility.
TIE-INNozzle additions, reinforcement checks, and re-rating support for vessels, tanks, and exchangers under revised process conditions.
STATIC EQUIPMENTRe-analysis of existing stress models against modified routing, supports, or operating cases — flagged against the original design basis.
STRESSTurning field markups into clean, issued P&IDs and isometrics — and reconciling drawings against what's actually built.
DOCUMENTATIONAssembling the calculation sets, drawings, and change records a management-of-change review actually needs — indexed and traceable.
MOC / QAMost brownfield packages touch more than one discipline. Each is planned and checked against the discipline codes below.
PFD/P&ID updates, relief & blowdown re-checks, hydraulic re-verification for modified systems, MOC technical basis.
Routing and layout revisions, tie-in point studies, isometrics, line lists, material take-offs.
Flexibility analysis and re-checks, support and restraint re-design, nozzle load verification against equipment allowables.
Vessel, tank & exchanger modifications — nozzle reinforcement, re-rating support, fitness-for-service inputs.
Pipe rack and support modifications, foundation adequacy checks, structural steel for new tie-ins and platforms.
Cable routing & tray revisions, load list updates, area classification impact checks for modified equipment.
Instrument index updates, loop drawing revisions, SIS/interlock impact review for tie-ins and modifications.
Independent checking, as-built reconciliation, calculation traceability, and dossier compilation across every discipline above.
