potential

At first glance, the opportunity appeared relatively straightforward: provide cleaning services to a major visitor attraction. The underlying specification told a very different story. It contained hundreds of individual cleaning requirements covering different areas of the site, different activities and significantly different service frequencies.

For a contractor preparing a price, the challenge was not simply:

Not

"How much should we charge?"

But

"What exactly are we being asked to deliver, how often must we deliver it, how much labour will it require, and what will it actually cost?"

The Challenge

The Fort Nelson specification contained 219 individual service requirements. Those requirements covered everything from frequently repeated cleaning activities through to periodic and as-required tasks. MobiliseHQ identified 214 unique Service Area + Task + Frequency combinations, while retaining all 219 source requirements. Nothing from the original specification was discarded.

The frequency analysis identified:

106

Daily

7

Hourly

33

Weekly

10

Monthly

29

Biannual

30

Annual

4

As Required

This immediately demonstrated why simply looking at the number of specification lines would not provide a meaningful basis for pricing. A task undertaken once a year has a completely different labour implication from a task undertaken every day.

The MobiliseHQ Approach

MobiliseHQ transformed the cleaning specification into a structured operational model. Instead of treating the tender document as a long list of cleaning instructions, each requirement could be understood in terms of:

Service Area
Cleaning Activity
Required Frequency
Number of Occurrences
Time Required
Labour Requirement
Cost

This creates the bridge between the procurement specification and the contractor's commercial pricing model.

From Frequency to Workload

One of the most important stages is converting written frequencies into measurable occurrences. For example, MobiliseHQ identified 362 daily occurrences per year within the Fort Nelson service model. That allows the contractor to move beyond statements such as:

From

"This task must be completed daily."

To

"How many times will we actually have to perform it during the contract year?"

The same principle can then be applied across weekly, monthly, biannual and annual requirements. This creates a measurable annual workload rather than a collection of written instructions.

From Workload to Labour

Once the frequency has been established, the contractor can apply its own operational knowledge. For each activity, the contractor can determine how long the activity will take and how many operatives are required.

Occurrences × Duration × Number of Operatives = Annual Person-Hours

For example, if an activity occurs 362 times per year, takes 30 minutes and requires one operative:

362 × 0.5 hours × 1 operative181 annual labour hours
362 × 0.5 × 2 operatives362 annual labour hours

This is where MobiliseHQ begins converting a tender specification into a genuine delivery model. The same calculation can be repeated across the specification to aggregate daily, weekly, monthly and annual labour requirements — and ultimately total contract labour hours.

A small error in the assumed time for a frequently repeated activity can become a significant commercial error when multiplied across an entire year — and potentially across a five-year contract.

TUPE Cannot Be Considered in Isolation

The Fort Nelson opportunity also demonstrates why pricing cannot simply be based on the existing workforce. Where TUPE applies, information about transferring employees is extremely important. But TUPE data answers one question — "What workforce may transfer to the incoming contractor?" — it does not necessarily answer "What workforce is actually required to deliver the new specification?"

MobiliseHQ allows the contractor to build the workload requirement from the specification first. The resulting labour requirement can then be compared against the TUPE information. This can help identify whether:

  • the existing workforce appears sufficient;
  • additional labour may be required;
  • working patterns may need restructuring;
  • there may be excess capacity;
  • supervisory resources need to be considered; or
  • the proposed service model needs further investigation.

This turns TUPE from something that is simply accepted as a tender cost into something that can be tested against the actual service requirement.

Labour Is Only the Beginning

A viable tender price cannot be calculated from wages alone. Once the operational workload has been established, the contractor also needs to consider the wider cost of delivering the Fort Nelson contract:

Management and supervision
Employer National Insurance and pension costs
Holiday and sickness cover
Cleaning equipment
Cleaning materials and consumables
PPE and uniforms
Travel and transport
Training
Technology and reporting systems
Insurance and compliance
Mobilisation costs
Contract management
Contingency and operational risk

MobiliseHQ provides a structure for bringing these costs together rather than allowing them to remain disconnected across spreadsheets, tender documents and individual calculations.

From Cost to Tender Price

Once labour and additional operating costs have been established, the contractor can calculate the estimated annual cost of delivering the contract. The commercial process then becomes:

Annual Labour Cost
Management & Supervision
Equipment & Materials
Travel & Operational Costs
Technology & Compliance
Mobilisation
Risk / Contingency
Estimated Contract Delivery Cost

The contractor can then apply its required commercial margin. For example:

Estimated annual delivery cost£82,000
Target commercial margin (10%)£8,200
Illustrative annual tender price£90,200
£90,200 × 3 years£270,600
Authority's initial 3-year estimate~£270,000

The figures above are illustrative. The purpose is not for MobiliseHQ to determine what the contractor should charge — its purpose is to allow the contractor to understand what its own assumptions mean commercially.

Testing Commercial Viability

This is where the model becomes particularly valuable before a bid is submitted. Suppose the contractor's detailed operational model produced an annual cost of £95,000 before profit. If the authority's indicative annual budget was approximately £90,000, that would immediately raise an important question.

The contractor could investigate:

  • Are our productivity assumptions too conservative?
  • Have we misunderstood part of the specification?
  • Can the service be delivered differently?
  • Are TUPE costs creating an issue?
  • Is the authority's budget commercially realistic?
  • Should we bid at all?

That is a far better position than discovering after winning the contract that the price submitted cannot support the required service.

Protecting Margin

The reverse is equally important. A contractor might initially believe it needs to bid £90,000 per year simply because that appears to be the authority's anticipated budget. But its detailed MobiliseHQ model might demonstrate that the contract can be delivered properly for £72,000. If the contractor automatically reduces its tender price to £75,000 in an attempt to be competitive, it could unnecessarily give away a substantial amount of potential margin.

MobiliseHQ therefore helps answer two different questions:

Question 1

What will the contract cost us to deliver?

Question 2

What should our commercial tender price be?

Those are not necessarily the same number.

Creating an Evidence Trail

The Fort Nelson model also creates something that is often missing from tender pricing: a clear explanation of how the price was reached. Instead of a final figure sitting at the bottom of a spreadsheet with little connection to the specification, the contractor can trace the commercial logic:

Specification
Frequency
Annual Occurrences
Activity Duration
Person-Hours
Labour Cost
Additional Contract Costs
Commercial Margin
Tender Price

This provides a much stronger foundation for internal approval, pricing discussions and mobilisation if the contract is subsequently won.

From Bid to Mobilisation

The value of the model does not necessarily end when the tender is submitted. If the contractor wins Fort Nelson, much of the information required for mobilisation has already been structured. The contractor already has visibility of:

What needs to be cleaned
Where it needs to be cleaned
How frequently
The assumed labour requirement
The proposed staffing model
The underlying cost assumptions

The tender pricing exercise therefore becomes the starting point for operational mobilisation rather than a spreadsheet that is forgotten once the procurement process ends.

The Result

Fort Nelson demonstrates how MobiliseHQ can transform a complex cleaning specification containing 219 individual requirements into a structured commercial model. The contractor moves from:

219 specification requirements
214 structured Service Area + Task + Frequency combinations
measurable annual workload
labour requirement
contract delivery cost
commercial tender price

Most importantly, zero specification requirements are lost during that process.

Why It Matters

Public-sector tender pricing often begins with an authority's pricing schedule and ends with a contractor trying to decide what number to enter into it. MobiliseHQ approaches the problem from the opposite direction. It asks:

  • What are we actually required to deliver?
  • How often must we deliver it?
  • What resources will it require?
  • What will those resources cost?
  • What other costs must the contract support?
  • What margin do we require?

Only then does it arrive at the tender price. That changes pricing from an educated guess into a structured commercial decision.

Specification → Frequency → Workload → Labour → Additional Costs → Contract Price

MobiliseHQ turns complex tender specifications into measurable, costed delivery plans — helping contractors understand the contract before they price it.
