Pre-Contract Delivery & Commercial Modelling

Don't just bid for the contract. Understand how you'll deliver it.

Winning a public-sector contract is only worthwhile if you can deliver it successfully and profitably.

That's why HCB Consultancy clients can now benefit from MobiliseHQ — our pre-contract planning, pricing and mobilisation platform designed to turn tender specifications into practical delivery models.

Rather than simply completing a tender response and asking the contractor to work out the pricing, MobiliseHQ allows HCB Consultancy to work with the contractor to understand what the contract could actually require from their business — from staffing and labour costs to equipment, management, TUPE, mobilisation, risk and margin.

The objective: build a tender that is not only capable of winning, but capable of being delivered.

From Tender Documents to a Delivery Model

Structuring the procurement pack into a model

Public-sector procurement packs can contain specifications, pricing schedules, property/site information, TUPE information, clarification responses and contractual requirements. MobiliseHQ helps structure this information into a pre-contract delivery model. Depending on the opportunity, HCB Consultancy and the contractor can assess:

Service locations and requirements

Tasks and frequencies

Labour hours and productivity

Staffing structure

TUPE workforce and employment-cost exposure

Additional recruitment requirements

Wages and employment on-costs

Management and supervision

Equipment and machinery

Materials and consumables

Vehicles and travel

Mobilisation requirements

Contingency and commercial risk

Overheads

Target margin

Relationship between contract value, cost of delivery and potential profitability

The model is tailored to the individual procurement — not every tender requires every modelling component.

The MobiliseHQ Difference

A different way to approach tendering

A tender price shouldn't be a number you arrive at and then hope works. MobiliseHQ helps us build the delivery model first — and use that model to inform the tender, pricing and mobilisation plan.

Traditional approach

Price first, delivery afterwards

Tender responses and mobilisation built around the model

Tender Writing tells the buyer how you will deliver.

MobiliseHQ helps work out how you will actually deliver.

HCB Consultancy combines the two.

Labour Modelling

Small assumptions, big commercial impact

Labour-intensive contracts can be particularly sensitive to small differences in productivity and staffing assumptions. MobiliseHQ allows HCB and the contractor to progressively build the labour model using the contractor's own operational knowledge and assumptions.

What needs doing

How often

How long it takes

Labour hours required

Workforce required

Employment cost

The labour model is built around the contractor's actual operational knowledge — the tasks, frequencies and durations they recognise from running similar services — so the model reflects how the work is really delivered, not a generic assumption.

As each assumption is entered, MobiliseHQ rolls the labour hours up into a workforce requirement and employment cost, giving a clear picture of the staffing needed to deliver the specification.

TUPE Modelling

TUPE without the spreadsheet headache

Where TUPE applies, MobiliseHQ can incorporate Employee Liability Information into the pre-contract model and help assess potential employment-cost exposure.

Existing TUPE Workforce

Contractual Hours

Employment Costs

Proposed Service Requirement

Potential Additional Workforce / Surplus Capacity

MobiliseHQ supports commercial modelling of potential employment-cost exposure. It does not provide legal advice and does not determine whether TUPE applies or the extent of any TUPE liability. Legal advice on TUPE should be taken separately where required.

Contract Cost Building

Labour is only one component of contract cost

MobiliseHQ brings the principal cost categories together so the full cost of delivery can be understood. Overheads, contingency/risk and profit can then be considered separately.

Direct LabourSupervisionManagementEquipmentMaterialsConsumablesVehiclesTravelTrainingTechnologyMobilisationSubcontractorsOther Costs

Contract Value

The buyer's published or estimated contract value — a commercial benchmark for the opportunity, not guaranteed revenue.

Cost of Delivery

The full modelled cost of delivering the contract — labour, management, equipment, materials, vehicles and mobilisation.

Commercial Risk

Contingency and risk allowance, considered separately from the day-to-day delivery cost.

Potential Margin

The commercial return indicated after modelled delivery costs, overheads and risk have been considered.

Work-in-Progress Modelling

Build the commercial model while information is still being gathered

Tender pricing does not normally arrive fully formed on day one. MobiliseHQ allows HCB and the contractor to build a working commercial model while information is still being gathered.

Where information is incomplete, the platform can distinguish between areas that have been modelled and those still awaiting information — rather than treating missing information as zero cost.

The model develops alongside the tender.

Labour requirements

Staffing gaps

TUPE exposure

Incomplete cost categories

Contractor information requirements

Budget pressure

Stronger Tender Responses

Not simply a pricing tool

The delivery model developed during pre-contract planning can provide a stronger factual basis for written responses. Instead of relying solely on generic method statements, HCB can write responses around the delivery approach that has actually been developed with the contractor.

The work doesn't end at submission

The work undertaken in MobiliseHQ does not have to end when the tender is submitted. If the contract is awarded, the staffing assumptions, service requirements, risks, equipment requirements, management arrangements and mobilisation commitments developed during the bid can provide the foundations for mobilisation.

Case Study — LiveWest Cleaning Services

Building a Multi-Contractor Pricing Model Across 351 Properties

The Challenge

A specialist window cleaning contractor identified an opportunity to bid for LiveWest's Window and Communal Cleaning contract across the South West.

The opportunity has an estimated total value of £4.25 million, with an initial two-year contract period and the potential for three further 12-month extensions.

For a specialist SME, the scale of the opportunity presented an immediate commercial challenge. The contractor had the capability and experience to deliver the window cleaning element but did not intend to directly employ the workforce required to undertake every service within the specification.

A viable delivery model therefore needed to combine:

Window Cleaning

Lead contractor delivery

Communal Cleaning

Subcontracted delivery

Bio / Specialist Cleaning

Reactive or unit-priced delivery

The challenge was not simply identifying subcontractors. The lead contractor needed to understand the complete LiveWest requirement, establish the labour requirement for each workstream, incorporate subcontractor costs, add its own management and commercial costs, and ultimately arrive at a defensible contract price.

The MobiliseHQ Approach

MobiliseHQ converted the LiveWest procurement information into one structured contract workspace. Rather than treating the tender as one enormous cleaning specification, the platform separated the requirement into distinct operational workstreams:

Window Cleaning

Lead contractor delivery

Communal Cleaning

Subcontracted delivery

Bio / Specialist Cleaning

Reactive or unit-priced delivery

This allows each organisation involved in delivering the contract to contribute to the part of the pricing model it understands, without requiring one person to estimate every element of the contract.

Turning the Property Schedule into Workload

The LiveWest pricing information contained hundreds of individual property/service relationships. MobiliseHQ imported, reconciled and validated the schedules and created:

351

physical contract properties

332

Communal Cleaning property/service relationships

252

Window Cleaning property/service relationships

Across those properties, the platform identified active property/service relationships and the imported schedules generate:

13,676

scheduled Communal Cleaning visits / year

1,512

scheduled Window Cleaning visits / year

Bio Cleaning is maintained separately because it is a reactive/unit-priced service rather than a predictable scheduled workload. This transforms a large property spreadsheet into an operational delivery model.

Calculating the Lead Contractor's Window Cleaning Cost

The lead window cleaning contractor does not need to price hundreds of properties individually. MobiliseHQ asks for two core operational assumptions:

Assumption 1

Typical visit duration

Assumption 2

Number of operatives

The calculation is then:

Visit Duration × Number of Operatives = Person-Hours per Visit

For example, if the contractor determines that a typical visit requires 2 operatives × 1.5 hours = 3 person-hours, MobiliseHQ can apply that assumption across the 1,512 scheduled annual Window Cleaning visits.

1,512 visits × 3 person-hours4,536 annual labour hours
4,536 hours × £20/hr (illustrative)£90,720 annual direct labour

The £20 hourly cost in this example is illustrative rather than an actual LiveWest tender assumption. The contractor can then override individual properties where access, building configuration or other known circumstances mean that the standard visit assumption is inappropriate. This provides a baseline without requiring the contractor to manually price all 252 Window Cleaning property relationships.

Calculating the Communal Cleaning Subcontract

Communal Cleaning can be modelled independently. Rather than asking the window cleaning contractor to estimate work outside its specialist area, the communal cleaning subcontractor provides its own operational assumptions.

Typical visit duration × Cleaning operatives × Scheduled visits

If, purely for illustration, the average communal visit required 1 operative × 1.25 hours = 1.25 person-hours, applied to the 13,676 scheduled annual Communal Cleaning visits:

13,676 visits × 1.25 hours17,095 annual labour hours
17,095 × £18/hr (illustrative)£307,710 direct labour

The subcontractor can refine the model where particular properties require different labour assumptions. The important distinction is that the specialist cleaning contractor contributes the operational knowledge required to calculate the Communal Cleaning workload, while the lead contractor retains control of the overall commercial model.

Adding the Subcontractor Commercial Price

Labour cost is not necessarily the price charged by the subcontractor. The communal cleaning company may need to include supervision and management; equipment and materials; travel; holiday and absence cover; insurance and compliance costs; overhead recovery; and profit.

Direct communal labour cost£307,710
Other operational costs£35,000
Subcontractor overhead and profit£42,000
Annual subcontract price to lead contractor£384,710

MobiliseHQ can therefore distinguish between the underlying operational cost and the commercial amount that needs to be incorporated into the lead contractor's tender price.

Bio and Specialist Cleaning

Bio Cleaning presents a different pricing problem. It is reactive and cannot necessarily be forecast using a fixed annual visit schedule. Rather than forcing it into the same labour model, MobiliseHQ allows the workstream to be priced using appropriate units such as:

Call-out charge
Hourly specialist labour rate
Specific treatment/service rate
Materials or disposal charge

This means different types of service can sit within the same contract model without being forced into the same pricing methodology.

Building the Lead Contractor's Commercial Model

Once each workstream has been calculated, MobiliseHQ can bring the costs together.

Direct Window Cleaning Delivery£90,720
Communal Cleaning Subcontract£384,710
Forecast Bio / Specialist Cleaning£30,000
Initial service delivery cost / year£505,430

The lead contractor then needs to consider the costs associated with managing the overall LiveWest contract. For illustration:

Contract management£30,000
Vehicles, equipment and operating costs£25,000
Technology, administration and compliance£12,000
Contingency / operational risk£20,000
Service delivery cost£505,430
Lead contractor additional costs£87,000
Total estimated annual contract cost£592,430

The lead contractor can then determine the commercial margin required. For example, applying a 10% margin to cost would produce:

£592,430 × 10% margin£59,243
Illustrative annual tender price£651,673

Again, these figures are illustrative. MobiliseHQ's purpose is not to decide what a contractor should charge; it provides the structure through which the contractor can test its own assumptions.

Testing the Price Before Submission

One of the most important benefits of the model is the ability to see what happens when an assumption changes.

  • If window-cleaning visits take longer than expected, MobiliseHQ can show the effect on annual labour.
  • If the communal-cleaning subcontractor revises its price, the impact can be incorporated into the overall model.
  • If wage rates increase, labour costs can be reassessed.
  • If the lead contractor changes its target margin, the tender price can be recalculated.

From

"What figure should we put in the pricing schedule?"

Towards

"What will this contract actually cost us to deliver, and what price produces an acceptable commercial return?"

Protecting the Lead Contractor's Commercial Position

A subcontractor's contribution does not mean that every organisation involved needs access to the complete commercial picture. The model can separate:

1Operational assumptions
2Subcontractor pricing
3Lead contractor overhead and margin
4Final tender price

This is particularly important where an SME is assembling a delivery partnership to compete for a contract larger than it could comfortably deliver alone. The window cleaning contractor can retain ownership of the LiveWest bid and commercial strategy while drawing on specialist partners for the services they are best equipped to deliver.

From Tender Documents to Contract Price

For LiveWest, MobiliseHQ creates a clear commercial chain:

Tender Specification
351 Physical Properties
Window + Communal + Bio Workstreams
Scheduled Service Visits
Labour Requirements
Direct Delivery + Subcontractor Costs
Contract Management & Overheads
Risk & Contingency
Commercial Margin
Final Tender Price

The Result

A complex multi-service tender can be transformed into a structured commercial delivery model. Instead of requiring one SME to possess every capability internally, MobiliseHQ supports a lead-contractor model in which specialist businesses contribute to individual workstreams while the bidding organisation retains control of the overall contract.

The lead contractor can understand:

  • how many services must actually be delivered;
  • how much labour is required;
  • which elements will be delivered directly;
  • which elements will be subcontracted;
  • what those subcontractors will cost;
  • what additional costs arise from managing the contract; and
  • what tender price is required to achieve the desired commercial return.

Why It Matters

Large public-sector contracts can appear inaccessible to smaller specialist contractors because the specification often combines several different services into one procurement. But the ability to deliver every service directly is not necessarily the same as the ability to manage the delivery of the contract.

MobiliseHQ provides the commercial and operational structure needed to bring multiple specialist organisations together. For a contractor considering an opportunity such as LiveWest, the question changes from:

From

"Are we big enough to deliver all of this ourselves?"

To

"Can we build, cost and manage the right delivery model?"

That opens a very different category of public-sector opportunity to ambitious SMEs. MobiliseHQ turns complex tender requirements into a measurable delivery model — from specification, through labour and subcontracting, to a commercially defensible tender price.

MobiliseHQ Case Study

Fort Nelson — Turning a Complex Cleaning Specification into a Structured Pricing Plan

The Royal Armouries cleaning services opportunity at Fort Nelson presented the type of challenge that contractors regularly encounter when bidding for public-sector cleaning contracts.

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.
