Design & Engineering

Engineering That Moves From
Concept to Construction

The quality of your engineering determines the quality of your installation. A project with incomplete drawings, ambiguous specifications, or poorly defined safety logic will generate problems at every stage, from procurement through to commissioning and handover.

At Touch Teq Engineering, we work at the front end of the project lifecycle, where the decisions that shape everything downstream are made. We take your operational requirements, your process hazards, your regulatory obligations, and your site-specific constraints, and we translate them into a complete engineering design that your construction team can execute with confidence.

Our approach is grounded in practical experience. Because we also deliver installation and commissioning services, our engineers understand what happens when a design meets the reality of a working plant. We know which cable routing arrangements cause access problems during construction. We know which junction box layouts make termination difficult in confined spaces.

What We Offer

Full-Scope Engineering from Early Concept Through to As-Built Records

01

Front-End Engineering Design (FEED)

We help define the technical direction of your project before you commit to construction. This includes developing system architectures, preliminary single-line diagrams, equipment sizing, detection philosophy documents, and cost estimates.

02

Detailed Engineering Design

We produce the complete technical packages required to build your systems. This includes cable schedules, loop diagrams, wiring diagrams, termination details, cause and effect matrices, equipment specifications, data sheets, and layout drawings.

03

P&ID Development and Verification

We develop, review, and update P&IDs that accurately represent your process and instrumentation configuration. For existing facilities, we conduct site verification walkdowns to ensure your P&IDs reflect the actual installed condition.

04

Cause and Effect Matrix Development

For safety-critical systems, we develop detailed cause and effect matrices that define exactly how the system must respond to each input. Every alarm, trip, and output action is mapped, cross-referenced, and validated.

05

Fire and Gas Detection System Design

We engineer the complete detection layout for fire and gas systems, including the selection and placement of gas detectors, flame detectors, heat detectors, smoke detectors, and manual call points based on gas dispersion analysis.

06

Protection and Safety Studies

We perform the engineering calculations that underpin safe system design, including electrical protection coordination studies, fault level calculations, discrimination studies, cable sizing verification, and voltage drop analysis.

07

Drafting and CAD Services

Our drafting capability supports the production of clear, accurate, and standards-compliant technical drawings, including 2D layouts, single-line diagrams, P&IDs, and equipment location plans.

08

Reverse Engineering and Legacy Plant Documentation

We help clients regain control of undocumented systems by tracing existing installations from the field device to the control system, identifying every component, and producing updated drawings and schedules.

09

As-Built Documentation

We update all project drawings and documents to reflect the final installed condition on site. Accurate as-built records are a fundamental requirement for ongoing maintenance and compliance audits.

010

Bill of Materials and Procurement Support

We produce detailed bills of materials derived directly from the engineering design, ensuring that every item ordered has a clear link to a drawing, a specification, and a location on the plant.

011

Independent Design Review

We perform independent technical reviews of engineering packages produced by EPC contractors, system integrators, or other consultancies. Our reviews assess compliance with applicable standards, technical accuracy, constructability, and alignment with the project's safety objectives.

Our Expertise

Integrated Design Across Three Core Technical Disciplines

Fire and Gas Detection System Design

Detection philosophy development, detector selection and placement, coverage mapping and gas dispersion analysis, cause and effect matrix development, alarm management, and integration with plant safety systems.

Control and Instrumentation (C&I) Engineering

Instrument selection and specification, loop design, wiring and termination engineering, control narrative development, safety instrumented system (SIS) design, SIL verification, and marshalling design.

Industrial Electrical Engineering

Power distribution design, single-line diagrams, cable sizing and route engineering, protection coordination, earthing and lightning protection, hazardous area electrical design, and MCC specification.

How We Work

A Structured Methodology from Requirements Through to Construction Issue

1

Requirements Capture and Basis of Design

We establish what the system needs to achieve by reviewing project scope, safety studies (HAZOP, SIL), regulatory requirements, and client engineering standards.

2

Concept and System Architecture

We develop the system concept, including block diagrams, preliminary single-line diagrams, detection philosophy, and overall system architecture.

3

Detail Engineering

This is where the concept is developed into the full construction documentation: P&IDs, loop drawings, cable schedules, termination diagrams, and specifications.

4

Interdisciplinary Coordination

We coordinate our deliverables with other engineering disciplines (process, mechanical, civil, structural) to identify clashes and interface gaps.

5

Issue for Construction and Ongoing Support

We issue the final design package and remain available throughout construction and commissioning to respond to technical queries and review vendor submissions.

Risk Awareness

The Real Cost of
Poor Front-End Engineering

Rework During Construction

Equipment arrives on site and does not fit. Cables are routed to the wrong junction boxes. The installation team stops, costs climb, and schedules slip. Every day of waiting multiplies the cost.

Commissioning Delays

Logic errors in the cause and effect matrix, missing interlocks, and undocumented field modifications all surface during testing, turning commissioning into a troubleshooting exercise.

Compliance Exposure

Without a properly documented design basis, it is difficult to demonstrate to a regulator or insurer that your installation was engineered to the required standards.

Maintenance Burden

A poorly documented installation creates an ongoing problem. Without accurate loop drawings and as-built records, every fault-finding exercise takes longer than it should.

"The investment required to engineer a project properly at the front end is a fraction of the cost of fixing problems during construction."

Recovering, Updating, and Completing Documentation

Plants built decades ago may have undergone multiple modifications without documentation keeping pace. We address this systematically by conducting site walkdowns and tracing every circuit to produce accurate records.

Site verification walkdowns and condition assessments
Red-lining and updating P&IDs to reflect current condition
Producing as-built loop drawings and wiring diagrams
Updating cable schedules and termination records
Revising fire and gas detection layouts for modifications
Developing or updating equipment registers (HAER)
Documentation gap analysis and recovery prioritisation
