PLUMBING & ELECTRICAL SOLUTIONS
A building’s plumbing and electrical systems are invisible when they are working — and impossible to ignore when they are not. Leaking pipes behind finished walls, undersized circuits that trip under load, poorly graded drainage that backs up at first use — these are not minor inconveniences. They are the result of systems that were not properly designed, not correctly installed, or not honestly tested before the walls were closed. At DMMAC Construct, we treat plumbing and electrical as engineering disciplines, not afterthoughts — because that is what they are.
Our MEP team designs and installs complete plumbing and electrical systems for residential homes, commercial buildings, and renovation projects across Pakistan. Every system we deliver is drawn before it is installed, tested before it is concealed, and documented before it is handed over. The result is a building whose hidden systems are as well-engineered as everything you can see.

Our Process – Step by Step
1 | Briefing & Requirements Assessment We gather all relevant information — architectural drawings, building use, number of floors, occupancy levels, and any specific requirements — to fully understand the scope before any design work begins. |
2 | MEP Drawing Preparation We prepare complete plumbing and electrical layout drawings, coordinated with the architectural and structural drawings from the outset — so every pipe and every conduit runs exactly where it should, without conflicting with structure, finishes, or other services. |
3 | Material Specification & Approval We specify the correct materials — pipe sizes and grades, cable ratings, board specifications, and fitting types — and present them to the client for approval before procurement. No substitutions are made after approval without written consent. |
4 | Rough-In Installation All concealed services are installed in the correct sequence — conduit and electrical rough-in before plastering, plumbing pipework before screeding and tiling — so that no finished surface ever needs to be broken to run a pipe or pull a cable. |
5 | Testing Before Concealment Every pipe run is pressure-tested for leaks and every electrical circuit is continuity-tested before walls are plastered or floors are screeded. Nothing is closed in until it has passed inspection. Test records are kept at every stage. |
6 | First Fix Completion & Coordination We coordinate with the finishing trades — plastering, tiling, joinery — to ensure all services are correctly positioned for their final connections before surfaces are completed. No last-minute rerouting or surface cutting. |
7 | Second Fix Installation Sanitary fixtures, electrical fittings, switches, sockets, distribution boards, and all visible equipment are installed cleanly and precisely once finishing works are complete — in the correct positions shown on the approved drawings. |
8 | Commissioning, Testing & Handover All systems are commissioned and load-tested. As-installed drawings and test records are compiled. A formal handover is completed with the client — confirming everything is working as designed and providing a permanent record of all concealed services. |
Why Choose DMMAC
✓ | Designed Before It Is Installed — Every plumbing and electrical system we install is drawn first. You see the layout, approve it, and understand where every pipe and cable runs — before a single conduit is fixed or a pipe is buried. No guesswork. No surprises. |
✓ | Coordinated With Architecture & Structure — Our MEP team works from the same set of drawings as our architects and structural engineers. Clashes between services and structure are resolved on paper — not discovered on site after the concrete is poured or the wall is built. |
✓ | Tested Before It Is Concealed — The most important quality check in MEP installation happens before the walls close. We test every circuit and every pipe run before concealment — and we do not close a surface until it has passed. This is mandatory on every project. |
✓ | Qualified Technicians Throughout — Our plumbers and electricians are trained, experienced, and supervised by qualified engineers at every stage of the installation. Work is inspected progressively — not just at the end when problems are expensive to fix. |
✓ | Quality Materials, Specified in Advance — Cable ratings, pipe grades, fitting types, and board specifications are all agreed in writing before procurement begins. No substitution of specified materials is made without the client’s written approval. What is specified is what is installed. |
✓ | Safety Is Non-Negotiable — Correct earthing, proper circuit protection, appropriate cable ratings, pressure-tested pipework, and correctly graded drainage are standard on every DMMAC installation — not optional extras. We do not cut corners on safety. |
✓ | Complete MEP Under One Contract — Plumbing, drainage, hot water, cold water, electrical wiring, distribution, earthing, and backup power — all under a single MEP contract. No separate contractors to manage, no gaps in responsibility, no confusion about who is accountable for what. |
✓ | Residential & Commercial Experience — From a 3 Marla house to a multi-storey commercial building, our MEP team has the design capability and installation experience to deliver systems at every scale — sized and specified correctly for the actual building they serve. |
Frequently Asked Questions
Q: Why do I need MEP drawings — can’t the plumber and electrician just work from the architectural plans?
A: Architectural drawings show room layouts and finishes — they do not specify pipe sizes, cable ratings, circuit arrangements, or drainage gradients. A plumber or electrician working without MEP drawings makes critical engineering decisions on site, without calculation, and with no permanent record of what was installed or where. This is how most plumbing and electrical problems in Pakistani buildings originate. MEP drawings eliminate the guesswork and provide a record every future owner and maintenance team needs.
Q: When should plumbing and electrical work start during construction?
A: Rough-in work — all concealed conduit, pipe runs, and drainage — must be completed before plastering begins. This means MEP installation starts once the structural frame is complete and before any finishing trades arrive. Starting late is one of the most common causes of buried services being in the wrong position. We sequence our work correctly by default.
Q: Do you install the electrical board and all wiring, or only the rough-in?
A: We handle the complete electrical installation from start to finish: conduit and rough-in, full wiring, distribution board supply and installation, earthing, all fittings and switches, and final commissioning and testing. You do not need a separate contractor for any part of the electrical works.
Q: What is the difference between PPRC and UPVC pipes — which do you use?
A: UPVC is used for cold water supply lines and drainage. PPRC (polypropylene random copolymer) is used for hot water supply lines, as it withstands sustained water temperatures without deforming. We use the correct pipe material for each application — not the cheapest available option for everything.
Q: Can you integrate a solar panel system and inverter with the building’s electrical supply?
A: Yes. We design and install the complete electrical integration — solar panels, inverter, battery bank, changeover arrangements, and all protection equipment — correctly connected to the building’s distribution board. The integration is designed as part of the electrical system, not added on afterwards.
Q: Do you test the plumbing and electrical before the walls are finished?
A: Yes — and this is mandatory on every project we undertake. All pipe runs are pressure-tested for leaks and all electrical circuits are tested for continuity, insulation resistance, and correct earthing before any surface is closed. Test records are kept and provided at handover. No concealed service is closed in before it passes.
Q: Can you upgrade the plumbing and electrical in an existing building?
A: Yes. We undertake MEP upgrades in existing buildings — rewiring, distribution board replacement, pipe replacement, drainage remediation, and complete system upgrades. For occupied buildings, we phase the works to minimise disruption and ensure services remain available to unaffected areas throughout.
Q: What documentation do you provide at handover?
A: At handover we provide: as-installed MEP drawings showing the actual position of all concealed services, pressure test records for all plumbing systems, electrical test certificates for all circuits, commissioning records for all equipment, and operating instructions. This documentation is essential for any future maintenance, extension, or renovation work.
