Hitech Engineering, M&E Consultancy
Singapore since 1976.

50-YEAR ENGINEERING LEGACY GRADE 9 (22kV) LEW PROFESSIONAL ENGINEER (PE)

What began in 1976 as a boutique engineering practice has grown into one of Singapore's most experienced M&E consultancies. Founded by Er. Goi Lai Huat — a Grade 9 (22kV) Licensed Electrical Worker and registered Electrical Professional Engineer (PE) — Hitech has spent 50 years shaping Singapore's built environment.

Today, under the leadership of his son, Goi Si Hao — a Cornell-trained engineer — Hitech pairs 50 years of accumulated field knowledge with the analytical rigour and international perspective that a new generation brings.

Services: What we do

M&E Consulting

We design and deliver Mechanical & Electrical building services that perform — and that respect the architectural intent they serve. Our consulting engagements are structured across three tiers to match your project needs.

Tier 1: On-Demand Advisory

  • Execute specific authority submissions to clear immediate regulatory hurdles
  • Resolve site-specific constraints (ducted AC in restricted ceilings, lightning protection rods)
  • Audit contractor proposals for technical compliance and commercial fairness

Tier 2: Infrastructure Blueprint

  • Calculate electrical power and heat loads — size M&E provisions precisely
  • Design core system schematics (Electrical SLD & Plumbing) for safety and reliability
  • Specify resilient AC systems — single compressor failure leaves no room without cooling

Tier 3: Full Consultancy

  • Define technical design brief with architects & clients
  • Produce detailed M&E drawing sets and specifications for tender & construction
  • Manage full suite of Singapore authority approvals: SCDF, PUB, SP Group, BCA
  • Oversee construction progress, material approvals, contractor performance
  • Support through Defect Liability Period (DLP)
PE / Engineering Services

Full range of calculations and authority submissions: ETTV, MV airflow, power flow study (ETAP), motor starting analysis, Green Mark, sprinkler hydraulic calculations, lightning protection, AC heat load, duct/pump/pipe sizing.

LEW Services (Grade 9 / 22kV)

Licensing LEW: EMA licensing of building electrical installations and generators. Installation LEW: COR, COC, SLD endorsement; SP Group applications for power turn-on, PV installations, and HT service connections.

Approach: The Six Pillars

“What is essential is invisible to the eye.”
— Antoine de Saint-Exupéry

In engineering, this is the ultimate standard: if we have done our job perfectly, the user never notices our work—it remains unseen, but absolute. We protect this invisible integrity through six foundational pillars that bridge the gap between architectural ambition and technical reality.

Realising Architectural Vision

M&E should be shaped by architecture and quietly woven into it. We work side-by-side with architects and interior designers to ensure essential services are seamlessly integrated — preserving the aesthetic intent without compromising performance.

Right-Sized Engineering

We champion engineering that is precisely calibrated to your needs. Over-engineering inflates costs and consumes GFA unnecessarily. Under-engineering limits your future operational flexibility. Our value lies in getting this balance right: designing for what you need today, with clear headroom for how your systems should evolve.

Technical Versatility

From Jurong Island petrochemical plants to Nassim Road Good Class Bungalows, our ability to move between complex industrial requirements and design-sensitive luxury projects is unmatched among boutique M&E firms.

Deep Institutional Memory

50 years of Singapore practice means we carry knowledge that newer generations of engineers were simply never taught. Every era of construction had its own methods and constraints — understanding why things were done a certain way is what allows us to distinguish between what still holds and what needs to change. For A&A and AEI work, that institutional memory is the difference between an assessment and an informed one.

Hands-On Site Experience

We know what contractors can realistically execute — and at what quality. Our design decisions are grounded in site realities, so when field conditions demand a change, we adapt without losing sight of the project's intent.

Principal-Led Partnership

When you engage Hitech, senior engineer involvement is guaranteed — not just at the pitch stage. We remain present from the initial concept through to final handover, providing consistent expert oversight at every milestone.

THE LUXURY HOUSE PARADOX: HIGH WALLS ARE ONLY HALF THE PRIVACY EQUATION

True privacy is more than just high walls: it is ensuring that those invited into your home do not inadvertently become witnesses to your private life. In a recent bungalow project, the Master Bedroom Suite — complete with an ensuite living area, bathroom, walk-in wardrobe, and private pool — was designed as an Undisturbed Retreat.

AUTHORIZED INTRUSIONS: CLOSING THE INTERNAL BACKDOORS IN LUXURY DESIGN
Standard M&E design typically clusters equipment directly where it is used for installer convenience. In a luxury residential context, this traditional approach creates a persistent friction: it builds a "backdoor" into the most private corners of a home. Routine maintenance inevitably forces service personnel to enter the Master Suite.
The core challenge was to facilitate high-performance ACMV and pool systems while ensuring that no technician ever needed to step foot inside the sanctuary.
Privacy through unorthodox engineering is achieved by physically decoupling a property's mechanical footprint — including ACMV units, heat pump water heaters, and pool pumps — from the living space to ensure maintenance never requires entry into private suites.

SANDBOXING THE SERVICE LAYER: PROVIDING ACCESS WITHOUT EXPOSURE
To address this, we took the unorthodox step of physically separating the mechanical infrastructure from the residential sanctuary:
Decoupled ACMV: Relocated two ducted Fan Coil Units (FCU) from the Master Suite to the first-floor ceiling, routing cold air through four risers to the second floor.
Externalized Pool Infrastructure: The pump room is positioned on the first floor in a separate wing of the house, allowing pool maintenance to remain entirely independent of the living quarters.
Hot Water Reticulation: Designed a dedicated hot water loop, allowing the heat pump water heaters to be positioned in a separate wing of the house.

NATIVE PRIVACY: PROTECTING ARCHITECTURAL SPACE WITH ENGINEERING
By decoupling the service footprint, we realized the architectural vision of the home. This unorthodox approach protected the homeowner's privacy while allowing routine maintenance to proceed on schedule.
Architecture defines the space; Engineering enables the comfort.

IS YOUR SINGAPORE WAREHOUSE AN SCDF LIABILITY?

Most 1970s facilities fail the 2023 Fire Code without realizing it. Why risk operational downtime or insurance rejections due to unforeseen regulatory hurdles? Hitech recently performed a forensic fire safety audit for a 6,400m2 single-storey warehouse near Ubi/Eunos that was built in the 1970s.

THE METHODOLOGY: A SYSTEMATIC REGULATORY REVIEW
Hitech's audit protocol follows a three-step process to provide a full picture to our clients:

  1. BASELINE ESTABLISHMENT: We analyzed the original FSSD submission drawings and conducted a site walk to visually detect modifications made over the decades.
  2. GAP CATEGORIZATION: We distilled the applicable Fire Code clauses into a 12-Point Framework to pinpoint key compliance issues and produce a clear matrix that shows the way forward:
    • Max. Floor Area Per Compartment
    • Max. Cubicle Extent Per Compartment
    • Sprinkler Protection Requirement
    • Fire Engine Accessway Perimeter
    • Min. Width Of Fire Engine Accessway
    • Fire Hydrant Distance
    • Smoke Control System
    • Fire Alarm System
    • Max. Travel Distance
    • Min. Fire Rating Of Compartment
    • Min. Unprotected Opening
    • Min. Structural Fire Rating
  3. PRELIMINARY ADVISORY: Our QP formulated a high-level proposed Fire Safety Works plan to address identified gaps, delivering project cost forecasts and implementation schedules to guide the subsequent detailed design.

Tired of project delays? Let's get your compliance right the first time. Hitech Engineering specializes in navigating these complexities so you can focus on operations.
