Secure the power date. Prove the handover.
A data centre is judged on one date: the day the customer's first hall goes live. That date depends on the grid, on factory slots for long-lead equipment and on five levels of commissioning, and a liquidated damages clause usually sits behind it. From Chennai, Project Assure brings planning, controls, risk, forensic and PMO discipline to data-centre programmes for clients in India, the UAE, Saudi Arabia and Oman.
Power. Commissioning. Handover.
In brief
Data Centres consultancy
Data-centre project assurance is independent planning, controls, risk and delay analysis for the delivery of data centres, from the utility power date through long-lead equipment, MEP installation and L1 to L5 commissioning to phased handover. Project Assure provides it from Chennai for owners, developers, contractors and lenders in India, the UAE, Saudi Arabia and Oman.
Sub-sectors
Where we work in data centres.
Hyperscale campusesMulti-building, multi-phase campuses where the utility connection and phased hall release set the pace. One programme has to hold several buildings, a shared substation and the customer's capacity ramp.
ColocationShell and core built ahead of demand, then fitted out hall by hall as tenants sign. Tenant fit-out dates and staged commissioning need to sit in the same programme as the base build.
EdgeSmaller, repeatable sites delivered in numbers. The risk sits in permits, site power and logistics across many locations, so standard templates and portfolio reporting matter more than one deep schedule.
AI/HPC high-densityHalls built for high rack densities and liquid cooling. Coolant distribution, heavier power infrastructure and newer supply chains add commissioning steps and long-lead items the programme must carry.
Enterprise & sovereignFacilities built for one organisation or for government data. Security, data residency and approval gates add review cycles, and procurement rules shape how changes and delays are handled.

What we deliver
How our services apply
- Speed-to-power planningUtility connection, substation and energisation dates logic-linked into the programme, so the power date drives sequencing from day one.
- Long-lead equipment controlGenerators, UPS, switchgear, chillers and transformers tracked from specification to factory slot, witness test and delivery, tied to site logic.
- Commissioning and IST programmesL1 to L5 commissioning planned as dated activities with prerequisites and owners, so integrated systems testing is not squeezed at the end.
- Progress, cost and earned valueRules of credit for MEP and commissioning, with earned value and forecasts that reconcile with the programme each period.
- Schedule risk on the ready-for-service dateP50 and P80 dates for each data hall, driven by power, equipment and commissioning risk, not a single deterministic finish.
- Delay damages and EOT analysisDelay damages, extension of time and concurrency tested against the contemporaneous programme record, for owners and contractors alike.
- Phased handover and hall releaseSectional completion planned hall by hall, with documentation, training and operational readiness tracked to each release.
- PMO and governance reportingOne reporting rhythm for owner, contractor, operator and lender, with decisions, interfaces and risks owned and dated.
Method
From power to handover: the chain that sets the date
PowerFix the utility connection and energisation dates first. Every later activity depends on them, and they are the dates the project controls least.
EquipmentMap long-lead MEP from design freeze to factory slot, witness test and delivery. A late order shows here months before it shows on site.
InstallationSequence shell, core and data halls for phased release. Agree rules of credit for MEP progress so the forecast stays honest.
CommissioningPlan L1 to L5 with real durations and prerequisites. Integrated systems testing needs permanent power, complete controls and witnesses on site.
HandoverRelease halls in the order customers need them. Tie each release to its sectional date, its delay damages and its readiness evidence.
RecordKeep the contemporaneous record every period: updates, notices, progress and the reasons for change. Any later delay analysis will rest on it.

Regional practice
Data Centres in India and the GCC
India
The path to a ready-for-service date in India often runs through the state distribution utility and the Electrical Inspectorate: under the Central Electricity Authority (Measures relating to Safety and Electric Supply) Regulations, 2023, installations above the voltage the state has notified for self-certification need the Electrical Inspector's approval before they are energised. At the 33 kV-and-above connections typical of data centres, that approval is usually required. Late completion is usually argued under sections 55 and 74 of the Indian Contract Act, 1872, where the court awards reasonable compensation up to the agreed sum, and loss generally has to be shown unless it is hard to prove. Disputes generally go to arbitration under the Arbitration and Conciliation Act, 1996. Facilities of at least 5 MW IT load have had infrastructure status since the Ministry of Finance notification of 11 October 2022, which often brings lender reporting into the controls cycle.
United Arab Emirates
Capacity clusters around Dubai and Abu Dhabi, and in Dubai the DEWA energisation date usually sets when integrated systems testing can start. Since 1 June 2026, Federal Decree-Law No. 25 of 2025 has replaced the 1985 Civil Transactions Law: liquidated damages remain valid, but a court may reduce an agreed sum shown to be exaggerated or where the employer's own fault contributed to the harm, and contracts signed earlier may still turn on the 1985 law. Contracts are commonly FIDIC-based with bespoke amendments, and where the contract provides for arbitration, disputes go to arbitration under Federal Law No. 6 of 2018 (as amended), often at DIAC or arbitrateAD.
Saudi Arabia
The Communications, Space and Technology Commission's Data Centre Services Regulations, in force since 1 January 2024, require providers of data-centre services to register each facility by its stage of development, with a Qualifying category for data centres still under development. The Saudi Building Code 2024 has been mandatory since 30 June 2025, and Council of Ministers Decision No. 286 of 9 October 2024 made the occupancy certificate a condition of full electrical activation. Under the Civil Transactions Law (Royal Decree M/191), a court may, on the contractor's application, reduce agreed delay compensation that was overestimated or where the obligation was partly performed. Where a government entity tenders the facility without an exemption continued from the 2019 law, such as those for the Public Investment Fund and the Saudi Central Bank, Article 70 of Saudi Arabia's new Government Tenders and Procurement Law caps works delay penalties at 15% of contract value. See what the new procurement law changes.
Oman
Activity centres on Muscat and on Salalah, a landing point for subsea cables between Asia, Africa and Europe. Salalah sits on the Dhofar power system, which has run separately from the northern grid, and the second phase of OETC's Rabt interconnection is planned to join the two, so the connection route and date belong in the programme from the start. Under Article 267 of the Civil Transactions Law (Royal Decree 29/2013), a court may adjust agreed compensation to the actual damage on either party's application, so delay damages need a loss record behind them; private disputes may go to the Oman Commercial Arbitration Centre.
Our approach
How we work in data centres
We treat a data centre as a power and commissioning programme with a building around it. The programme starts from the energisation date and the ready-for-service commitment, works back through integrated testing, MEP installation and long-lead equipment, and keeps each period's record as if a delay analysis may one day depend on it. We do not design facilities and we are independent of contractors and suppliers, so our reports say what the evidence shows.

Data Centres: common questions
What does Project Assure do on data-centre projects?
We plan and assure delivery. That covers the integrated programme from power date to handover, long-lead equipment tracking, L1 to L5 commissioning plans, earned value reporting, P50 and P80 schedule risk, and delay analysis where liquidated damages or extensions of time are in issue. We do not design facilities. Our work tests whether the programme to deliver them is credible.
Why does speed to power drive data-centre schedules?
Because nothing can be tested or handed over without permanent power. The utility connection, substation works and energisation approvals often take longer than the building, and they are the dates the project controls least. We put them in the programme logic from day one, so a slipped grid date shows its effect on integrated systems testing and handover the week it happens.
How do delay damages work when data halls are handed over in phases?
Usually through sections. Under the FIDIC 2017 Yellow Book, Sub-Clause 8.8 sets delay damages per day after each Time for Completion, up to any maximum in the Contract Data, and Sub-Clause 10.2 reduces them in proportion to value when the Employer takes over a Part that is not itself a Section. Particular Conditions often change this, so we map each hall's dates against the signed contract.
Which types of data centre does Project Assure cover?
Six common types: hyperscale campuses, wholesale and retail colocation, edge sites, AI and high-performance computing halls, and enterprise or sovereign facilities. The controls discipline is the same throughout. What changes is where the risk sits: power and phasing on campuses, customer fit-out on colocation, repeatability on edge, cooling and power density on AI, and approval gates on sovereign builds.
Is the Data Centre Intelligence platform free to use?
Yes. Data Centre Intelligence at dc.projectassure.in is open access, with no sign-in. It maps 13,293 data-centre sites across 89 countries on a globe and scores market risk by data-centre type and geography, with the evidence or basis behind each rating. It is built to frame siting and phasing questions before a programme is fixed.
What has to happen before a data centre in India can be energised?India
Under the Central Electricity Authority (Measures relating to Safety and Electric Supply) Regulations, 2023, installations above the voltage the state has notified for self-certification need the Electrical Inspector's approval before they are energised. At the 33 kV-and-above connections typical of data centres, that approval is usually required. Add the utility's connection works and any green energy open access approvals, and the power path often becomes the critical path.
Are liquidated damages still enforceable in the UAE under the new Civil Transactions Law?UAE
Yes. Federal Decree-Law No. 25 of 2025, in force from 1 June 2026, keeps agreed damages valid. A court may still reduce an amount shown to be exaggerated, or where the employer's own fault contributed to the harm. Contracts signed before then may still turn on the 1985 law. Either way, the contemporaneous programme record decides how a late data-centre handover is treated.
Does a data centre under construction in Saudi Arabia need to be registered?Saudi Arabia
Yes, where it will provide data-centre services. The Communications, Space and Technology Commission's Data Centre Services Regulations, in force since 1 January 2024, register each facility by its stage of development, with a category for data centres under development. Registration does not replace building permits, and full electrical activation depends on the occupancy certificate, so both belong in the programme.
What should a data-centre programme in Oman allow for?Oman
The grid connection first. Salalah sits on the Dhofar power system, which has run separately from the northern grid, and the second phase of OETC's Rabt interconnection is planned to join them. Programmes in Muscat and Salalah should also allow for personal data rules under Royal Decree 6/2022, and for agreed delay damages that an Omani court can adjust to actual loss.
