What Should an Electrical Estimating Handover Include Before Construction Starts?
Winning the tender is not the end of the estimator’s job. The knowledge behind the price has to reach the people who will build it. A strong electrical estimating handover moves that knowledge from the estimating team to the delivery team, so the project manager and site crew know what was priced, what was assumed, what was left out and where the risks sit.
This guide covers what a handover pack should contain, how to run the handover meeting, the gaps that most often turn into variations, and who is responsible for what. It starts from award. How the estimate was prepared is covered elsewhere on this site.
Why Estimate to Project Handovers Fail
Most handovers fail quietly. The estimator moves on to the next tender, the project manager inherits a total and a folder, and the reasoning behind the price stays in the estimator’s head. Common causes:
- The handover is just a file transfer. A folder of PDFs and a spreadsheet is not a handover.
- Assumptions are never passed on. The price relied on the builder supplying temporary power, but the site team does not know that.
- Quote validity is missed. Supplier quotes expire, and orders get placed late or at a different price.
- Labour allowances are invisible. The site team is told the job value but not how many hours were allowed for each package.
- It happens too late. If the handover occurs after procurement has started, the first decisions have already been made without the information.
The result is usually the same: avoidable variations, missed claims and a margin that disappears in the first few weeks.
What a Handover Pack Should Include
Think of the pack as the electrical project handover documents the delivery team needs to run the job without calling the estimator every day.
1. Scope summary.
A short, plain-language description of what was priced, organised by package (power, lighting, switchboards, containment, communications, emergency systems, testing and commissioning). Include the drawing and specification revisions the price was based on, plus any addenda or clarifications received before submission.
2. Assumptions, inclusions and exclusions.
The tender qualifications are exactly as submitted, with a note on what each one means on site. If the price assumes the builder provides temporary power, core drilling or fire stopping, the project manager needs to know before those items are needed. Hand over the wording, not a paraphrase.
3. Takeoff and quantities.
The measured quantities by package and area, with the drawing references they came from. The delivery team can then check progress, order materials and spot changes against a known baseline. For what a proper takeoff contains, see what’s included in a professional electrical takeoff.
4. Supplier quotes and validity dates.
Every quote that supports the price, with the supplier, date, validity period, lead time and what the quote includes and excludes. Flag anything that expires before the likely order date, and any long-lead item such as switchgear. The reliability of these inputs affects every later cost decision, as explained in how supplier quotes affect electrical estimates and tender pricing.
5. Labour allowances.
Hours by package, the productivity assumptions behind them, crew mix and any allowance for supervision, testing and commissioning. This is the most useful number for the site team, because it is the budget they are actually working to.
6. Rates and the cost breakdown.
The pricing structure by cost code, so the project manager can track cost against budget from week one. Where a schedule of rates was submitted or agreed, include it, because it will be needed for variations.
7. Risks and allowances.
The risks the estimator identified, any contingency or risk allowance carried, and any provisional sums with their values and conditions. Say plainly where the estimator was uncertain.
8. Commercial and contract notes.
Payment terms, retention, claim dates, notice requirements, insurance and any special conditions that affect how the work is run or claimed.
9. Program and procurement information.
Lead times, key dates, staging assumptions, access constraints and the order dates needed to hold the program.
10. Contacts.
Who at the builder, supplier and consultant level has already been dealt with, and what was discussed.
If your team uses a standard review list before tender submission, the electrical estimating checklist for commercial projects is a good source to draw from when assembling this pack.
Sample Handover Checklist
Item | What to hand over | Owner | Done |
Scope summary | Package descriptions and document revisions priced | Estimator | |
Qualifications | Final tender exclusions, assumptions and clarifications | Estimator | |
Quantities | Takeoff by package and area, with drawing references | Estimator | |
Supplier quotes | Quotes with validity dates, lead times and inclusions | Estimator / Procurement | |
Labour allowances | Hours, crew mix and productivity by package | Estimator | |
Cost breakdown | Budget by cost code, rates and schedule of rates | Estimator / Commercial | |
Risks | Risk list, allowances and provisional sums | Estimator | |
Contract notes | Payment, notices, claim dates, special conditions | Commercial | |
Program | Lead times, staging, access and order dates | Project manager | |
Handover meeting | Held, actions recorded and owners assigned | Project manager |
Copy this table into your own template and add a sign-off line for both the estimator and the project manager.
If you need an estimate that arrives with its assumptions, quantities and quote register already organised for handover, our electrical estimating services can prepare the pack alongside the tender.
Handover Meeting Agenda
Hold the meeting as soon as possible after award, and before the first major order is placed. Allow about 60 to 90 minutes for a mid-sized project.
- Project overview (5 minutes). Client, contract type, value, key dates and the head contract’s main conditions.
- Scope walkthrough (15 minutes). Go package by package. Confirm what is in and what is out.
- Assumptions and exclusions (15 minutes). Read the qualifications aloud. Note which ones need action early, such as temporary power or builder’s work.
- Quantities and labour (15 minutes). Explain where the hours came from and where the estimator was tight or generous.
- Quotes and procurement (10 minutes). Review validity dates, lead times and what needs ordering first.
- Risks and allowances (10 minutes). Walk through the risk list and decide who monitors each item.
- Commercial points (5 minutes). Notice periods, claim dates and variation procedure.
- Actions and owners (5 minutes). Record everything, assign a name and a date.
Take minutes and file them with the pack. They become the first entry in the project record.
Common Gaps That Cause Variations Later
Most of the costly gaps are not pricing errors. They are information that never reached the site.
- Excluded items nobody told the builder about. If an exclusion was in the tender but nobody raises it early, the site finds out when the item is needed, and the conversation becomes a dispute.
- Superseded documents. The site works from a newer drawing set than the one priced. Without a record of the priced revisions, you cannot show what changed.
- Expired quotes. The price assumed a supplier figure that is no longer valid.
- Provisional sums with no owner. Nobody tracks them, and they are exceeded without notice.
- Verbal agreements. Something said during a tender clarification call that was never recorded.
- Productivity assumptions that do not match site conditions. The estimate assumed open access and the job is staged in an occupied building.
When one of these turns into extra work, the baseline from the handover is what lets you price it properly. See electrical variation estimating for how to do that.
Roles and Responsibilities
Role | Responsibility at handover |
Estimator | Prepares the pack, explains the basis of the price, answers questions in the first weeks |
Project manager | Accepts the handover, challenges assumptions, owns the budget and the risk list |
Site supervisor or leading hand | Confirms the labour allowances and sequencing are workable on site |
Procurement or purchasing | Takes over supplier quotes, checks validity and places orders |
Commercial or contracts manager | Owns notices, claims, variations and contract compliance |
In a small business one person may fill several of these roles. The responsibilities still need to be assigned, even if the names overlap. If the estimating was outsourced, the same applies: the external estimator prepares the pack and joins the meeting, and your project manager accepts it.
Making the Handover Stick
Three habits make the process hold up under pressure:
Make it a stage gate. No major orders or mobilisation until the handover is signed off.
Keep the estimator reachable. For the first few weeks the project manager will have questions the pack does not answer.
Close the loop. After the project, compare actual hours and costs with the handed-over allowances and feed the results back into future tenders. That is where the handover pays off twice.
Frequently Asked Questions
What is an electrical estimating handover?
It is the formal transfer of information from the estimating team to the project delivery team after a tender is won. It covers the scope priced, assumptions, exclusions, quantities, quotes, labour allowances and risks, so the team can deliver and manage the job against the same baseline the price was built on.
When should the handover happen?
As soon as possible after award, and before procurement starts or the site mobilises. Doing it after orders have been placed means the first decisions were made without the full picture.
Who should attend the handover meeting?
At a minimum, the estimator and the project manager. For larger jobs, add the site supervisor, procurement and the commercial or contracts manager.
What is the most commonly missed item?
Assumptions and exclusions. These are usually written in the tender submission but never explained to the people who need to act on them. Quote validity dates and provisional sum conditions are close behind.
Final Takeaway
A good electrical estimating handover turns an estimate into a plan. It gives the delivery team the scope, the assumptions, the quantities, the quotes, the labour allowances and the risks behind the number, and it records who owns what. Hold it early, keep it structured and sign it off before major orders go out.
