Construction Law & Dispute Resolution

Scenario

Following the UK Government’s decision to fund the single biggest investment in the North of England railway infrastructure since the industrial revolution, Tunnel Tiger Construction Limited (“the Contractor ”) was awarded a contract by Northern Powerhouse Rail Limited (“the Employer”) for the construction of a 10 m diameter railway tunnel linking Salford and Manchester (“the Works”).

A JCT 2016 Standard Building Contract With Quantities (SBC/Q) form of contract was signed by the Employer and the Contractor in respect of the Works. Incorporated into the Contract Documents was a ground investigation report including borehole data (“the GIR”).

In the length of the tunnel beneath Salford Cathedral the GIR identified “solid rock, laminated clay and glacial deposits” in the tunnel cross - section. The Contract Bills included an item relating to the excavation of reinforced concrete within that length of the tunnel with a measured quantity of 5 m3 that was priced by the Contractor at tender stage.

During the course of the Works, the Contractor uncovered a large reinforced concrete passageway running across the proposed route of the new tunnel beneath the cathedral. The Contract Administrator issued an instruction for the excavation and removal of the passageway “…in order that the Works can be completed…

The Contractor’s construction manager immediately mobilises heavy concrete breaking plant to site and sometime later submits an extension of time and loss and expense notice relating to the delay and additional cost that the Contractor would probably incur as a consequence of the prolongation and disruption caused by the removal of the culvert.

At a subsequent site valuation the Contractor’s graduate quantity surveyor includes an item under the Variation section for the excavation of 1000 m3 of reinforced concrete to the culvert (based upon agreed measurements taken on site with the Clerk of Works) using the rate in the Contract Bills. The Quantity Surveyor rejects the rate on the basis that: “the rate is too high and was clearly a mistake in the Contractor’s tender…” and that, in accordance with the contract, the Quantity Surveyor will determine “a fair rate”.

At the monthly progress meeting the cost overruns and delays relating to the Works are reported. The Employer’s project director turns to the Contract Administrator and states “ You need to follow the Quantity Surveyor’s approach - we are not having another Crossrail situation here”

The Contract Administrator subsequently writes to the Contractor regarding the extension of time and loss and expense notice stating:

“I refer to the time and money issues associated with the removal of the reinforced concrete passageway. I have discussed this matter with the Employer and, in his opinion, he believes that you should have realised that there was a likelihood of you encountering reinforced concrete given the industrial nature along the route of the tunnel and the fact that excavation and removal of reinforced concrete was measured in the Bill of Quantities.

In any event notices were not given immediately your construction manager became aware of the obstruction.

I am therefore unable to agree to any extension of time or loss and expense in respect of the concrete passageway

Task

You are required to prepare a report which provides advice to the Contractor in relation to the contractual position with regard to the following:

  1. Whether the Contractor is entitled to be paid additional monies in respect of the excavation and removal of the reinforced concrete and, if so, what the basis of the valuation should be. (700 words)

  2. Whether, in principle, the Contractor is entitled to an adjustment to the Completion Date and to payment for loss and expense in respect of the obstruction. (700words)

  3. Whether the Contract Administrator’s response to the request for an extension of time and loss and expense is appropriate. (500 words)

Your advice should be fully supported by reference to the relevant provisions of JCT SBC/Q 2016 together with relevant cases and any authorities in statute (if any) which should all be cited and referenced in accordance with the Harvard (APA 6th) style of referencing.

Short Introduction (that focuses on the task would  be good) setting out what you are going to do.

Construction Law & Dispute Resolution Report

Introduction

This report provides advice to Tunnel Tiger Construction Limited (the Contractor) regarding the contractual position in relation to the excavation and removal of a reinforced concrete passageway encountered during the construction of a 10 m diameter railway tunnel linking Salford and Manchester for Northern Powerhouse Rail Limited (the Employer). The advice focuses on three key areas: firstly, whether the Contractor is entitled to additional payment for the excavation of the concrete passageway and the appropriate valuation method; secondly, whether the Contractor is entitled to an adjustment to the Completion Date and associated loss and expense; and thirdly, whether the Contract Administrator’s response to the extension of time and loss and expense notice is appropriate. The analysis draws upon the JCT 2016 Standard Building Contract With Quantities (SBC/Q), relevant valuation clauses, notice requirements, and supporting case law to provide practical legal guidance.

Entitlement to Additional Payment for Excavation of Reinforced Concrete

The primary issue is whether the Contractor is entitled to additional payment for the removal of a reinforced concrete passageway discovered during tunnel excavation beneath Salford Cathedral. Clause 5.1 of the JCT SBC/Q 2016 contract provides that the Contractor is to carry out and complete the Works in accordance with the Contract Documents, while the Valuation Rules in Clause 5.6 govern the basis on which variations are to be valued.

The Contract Bills included a measured item for excavation of reinforced concrete with a quantity of 5 m³ priced at tender stage. However, the obstruction encountered measures 1000 m³, which significantly exceeds the tendered quantity. Clause 2.27 of the JCT SBC/Q 2016 defines a “Relevant Matter” as any circumstance affecting the Works which may give rise to an entitlement to an adjustment in time or payment. In this context, the unexpected reinforced concrete passageway constitutes a Relevant Matter not expressly priced in the Contract Bills.

JCT 2016 Clause 5.6.2 states that variations are to be valued using rates and prices included in the Contract Bills where appropriate. Where such rates are deemed inappropriate, a fair valuation must be determined. The Employer’s Quantity Surveyor has rejected the Contractor’s use of the tendered rate, asserting that it was a mistake. Case law in this context, such as Mears Ltd v Costain Ltd [2015], recognises that rates included in Contract Bills are presumed to be fair and reasonable unless evidence of an obvious error exists. The Contractor’s tendered rate was accepted in the contract and forms part of the agreed contractual terms. Unless clear evidence demonstrates a manifest pricing error, it should be applied to the variation valuation.

The valuation methodology should therefore follow Clause 5.6.3, which allows the application of a fair rate where the Contract Bills are insufficient. In determining this rate, the Contractor may rely on the tendered rate, adjusted to reflect the difference in scale, site conditions, or any additional work caused by the obstruction. The fact that the passageway was unforeseen and not identified in the ground investigation report (GIR) strengthens the Contractor’s position. Case law such as Obrascon Huarte Lain SA v HM Government [2018] highlights that unforeseen physical conditions not reasonably identifiable from site investigations can constitute grounds for payment adjustments.

In conclusion, the Contractor is entitled to additional payment for the excavation of the reinforced concrete passageway. The valuation should initially reference the rate in the Contract Bills unless convincingly demonstrated as a tendering mistake. If the rate is deemed inappropriate due to scale, the Quantity Surveyor should determine a fair valuation under Clause 5.6, taking into account the actual costs incurred and prevailing site conditions.

 

A Relevant Event is any circumstance affecting the Works that may entitle a contractor to an extension of time or adjustment to payment, such as unforeseen obstructions or Employer instructions.

Yes, tendered rates can be used unless there is clear evidence of a mistake. If the rate is inappropriate, Clause 5.6 allows the Quantity Surveyor to determine a fair valuation.

No. Minor delays in notifying the Contract Administrator do not necessarily prevent entitlement if the Relevant Event is significant and clearly impacts the Works.

Under JCT SBC/Q 2016, the Contract Administrator must act impartially and fairly when assessing extensions of time, variations, and loss and expense claims.

The examples from the tunnel project really helped me see how valuation and extensions of time work in practice.

Clear, professional, but still easy to follow. I especially liked the section on Contract Administrator impartiality, it made the law feel very relevant.
