Wondering what happens between your approved plans and the day the first machine switches on? That’s where **detailed engineering** and M&E (mechanical and electrical) works come in. **Detailed engineering** covers the piping, mechanical and electrical design of your factory, scoped to the building design and how it will be used. Raise machinery and specialist equipment at this stage, because power, piping, drainage, ventilation and floor loading all depend on it. As part of our factory construction work in Selangor [/ →](/) , our team then installs the mechanical and electrical systems set out in the design. Deciding early avoids the rework that happens when equipment is chosen after the building is designed. Here’s a simple habit that saves SME owners a lot of grief. Ask each machine supplier for a data sheet showing power rating, weight, and air, water and drainage needs before we finalise the drawings. Our guide to what detailed engineering covers [/guide/factory-detailed-engineering/ →](/guide/factory-detailed-engineering/) explains the drawings produced and where they sit in the project. ## Why Does Machinery Drive the Design? A factory’s services follow its machines. A press line, an oven or a compressor each brings its own needs: - **Power.** Most factories need **three-phase supply**. Larger loads may need a **substation**. We size the **distribution board** and cabling from your equipment list. See factory power supply and TNB [/guide/factory-power-supply-tnb/ →](/guide/factory-power-supply-tnb/) . - **Piping and drainage.** **Process piping**, compressed air, water and process drainage are routed before the slab is cast. - **Ventilation.** Heat, fumes and dust need extraction planned with the roof and walls. - **Floor loading.** Heavy machines need foundations or thickened slabs at the right places. The power line is where most SME owners get caught out. According to TNB’s Electricity Supply Application Handbook (ESAH 3.1), the maximum demand of your factory decides the supply scheme: | Maximum demand | What TNB’s handbook says | | --- | --- | | Up to 72 kVA (100A) | Three-phase, four-wire, 415V supply | | Up to 350 kVA | A new 11/0.4kV substation may be needed, subject to a TNB system study | | Above 350 kVA, under 1,000 kVA | A new 11/0.4kV substation is required | | 1,000 kVA up to under 5,000 kVA | 11kV supply, with 11/0.4kV and/or 11kV substations | Treat this table as a guide only, because TNB confirms the final scheme for your lot. It does show why we ask for your equipment list early. A few extra machines can push you over the 350 kVA line, and that changes your land use, budget and timeline. When these are decided late, floors get cut, drains rerouted and cables upsized. Our guide on why machinery must be decided early [/guide/decide-machinery-early/ →](/guide/decide-machinery-early/) explains what to prepare. ## When Do You Need to Plan for a Crane? If your process uses an **overhead crane**, the building must be designed for it from the start. Crane loads go through the runway beams into the columns and foundations, and the hook height and span set the building height and grid. The crane type also changes the structure. A top-running crane rides on rails on runway beams, which sit on the building columns or on separate crane columns. A 2026 design guide from PEB Steel notes that underslung cranes hang from the roof beams and suit lighter duty, typically 1 to 15 tonnes. The crane itself comes from your specialist, but the structure is ours to get right. Tell us the crane type, capacity and span early, and we can size columns and foundations once instead of strengthening them later. See planning a factory building for an overhead crane [/guide/factory-overhead-crane-structure/ →](/guide/factory-overhead-crane-structure/) . ### Common Problems We Solve - **Not enough power** for new equipment, solved with early load assessment and **TNB power supply** planning. - **Late machinery changes** that would mean rework, avoided by asking for data sheets before design. - **Fire services added as an afterthought.** **Fire hydrants**, hose reels and the **sprinkler system** where required are designed in. Under the Uniform Building By-Laws 1984 (amended 2021), every building needs at least one hydrant within 30 metres of its entrance. Sprinkler systems follow MS 1910. - **Utility connections left unclear.** **Air Selangor water supply** and **Indah Water sewerage connection** responsibilities are written into the quotation. Air Selangor handles new development water applications through its eDPLAS system, so it helps to know who files what. ## How Are M&E Works Priced? M&E is quoted after detailed engineering, as part of the project quotation. The main cost drivers are your power demand, the amount of process piping and drainage, ventilation needs and fire services. We do not publish a price list. The quotation lists inclusions, exclusions and responsibilities, including who handles utility applications. Ready to see what your machines mean for power, piping and fire services? Send us your equipment list, and we’ll show you how detailed engineering and M&E works fit your factory before any price is set. report Sound familiar? ## Problems We Solve With Engineering and M&E warning ### Machinery needs special power or piping Heavy loads, compressed air, process water or extraction. We design the building services around your equipment list. warning ### Equipment decided late Changing machinery after the design is fixed means cutting floors, rerouting drains and upsizing cables. We ask for equipment details early. warning ### Not enough power on site Three-phase supply, a bigger connection or a substation may be needed. The TNB application sits in the project timeline, so we plan it early. warning ### A crane the building was not designed for Overhead cranes put large loads on columns and beams. The structure must be designed for them from the start. request\_quote Quotation scope ## What Does a Engineering and M&E Quotation Cover?

It covers power distribution and lighting, three-phase supply and any substation, water supply and drainage including process drainage, ventilation, and fire services such as hydrants, hose reels and sprinklers where required. It also covers provisions in the structure for heavy equipment such as overhead cranes. The output is a set of design drawings that the quotation and the installation are based on. ### Why does detailed engineering come before the quotation? expand\_more Because the quotation can only be accurate once the M&E is scoped. Power, piping, drainage, ventilation and floor loading all depend on your machinery and process. If they are guessed, the quotation is either padded or full of provisional sums, and changes later mean variations and rework. Doing the detailed engineering first lets us list exactly what is included and excluded, and lets you compare like with like. ### When should I decide my machinery? expand\_more As early as you can, ideally before detailed engineering starts. We need power ratings, weights, footprint, and any water, compressed air, drainage or extraction needs. Late changes can mean cutting floors, rerouting drains and upsizing cables, which costs time and money. Our guide on why machinery must be decided early explains what to prepare. ### Do you supply production machinery? expand\_more No. Machinery stays with you or your specialist supplier. We design the building and its services around your equipment, and the quotation states this clearly. ### Do I need a substation for my factory? expand\_more It depends on your total power demand. We estimate the load from your equipment list and advise whether a larger connection or a substation is needed. The TNB application has its own timing, so we raise it early. ### Can you design for an overhead crane? expand\_more Yes. The columns, beams and foundations must be designed for crane loads, height and span from the start. The crane itself is supplied by your specialist. A crane can only be added later if the structure was designed for it. ### Who installs the M&E systems? expand\_more The same team. We install, test and commission the mechanical and electrical systems set out in the detailed engineering. ### Do you handle water and sewerage connections? expand\_more We design the internal systems and coordinate the Air Selangor water supply and Indah Water sewerage connections. Who applies and pays for each is written into the quotation. ### Does every factory need sprinklers? expand\_more No. Fire protection depends on the use, size and storage. Requirements are confirmed during detailed engineering and reviewed by Bomba. menu\_book Guides ## Detailed Engineering and M&E Works Guides Plain answers to the questions owners ask before they commit.
