Coursework – The Quarry Road Project This contributes 40% to the final module mark You are the assistant civil engineer on the construction of a new access road. An access road is to be constructed into a new quarry which is being developed in the Yorkshire Dales to the north of Skipton. The works comprise: 10km of single carriageway flexible pavement construction with associated earthworks, fencing, drainage and kerbing Two culverts An Accommodation overbridge The diversion of a 660kV overhead electricity line. The work is to start on the first Monday in the next calendar year with the following non-work periods: Easter – One week Spring Bank holiday – One week Summer Bank Holiday – One week Christmas and New Year – Two weeks A five-day week will be worked.

Roadworks can continue whilst the bridge is being constructed, subject to appropriate health and safety provisions being in place. The site must be secured by fencing prior to earthworks. Surplus excavated material will be moved to or from the quarry. There is to be a one-week buffer between all roadworks operations. Please prepare: For the roadworks A long section of Quarry Road is attached. For this aspect of the project, prepare:

  1. A time-location analysis of the roadworks part of the scheme (25%)
  2. A schedule showing when each sub-contractor is needed and how many gangs are required (5%)

  2. A fully resourced and costed Programme of Works for the bridge construction, based on the WBS, in paper and MS Project formats (20%)
  3. A cumulative cashflow for the bridge construction (5%)

Regarding the contractual arrangements, you are to:

  1. Request additional information from the client relating to borehole logs, structural details of culverts, and key dates for the diversion of overhead cables, citing relevant NEC4 clauses supporting your request (5%)
  2. Prepare an Early Warning (Cl. 15.1) to the Project Manager about the risk to the key date for cable diversion not being met, and follow up with an Early Warning Meeting (Cl. 15.3) (5%)
  3. Draft a Compensation Event notification to the Project Manager regarding the missed key date, including relevant clauses (15%)
  4. Describe the process and clauses under the NEC4 ECC for addressing late payments following the claim acceptance (10%)

Include planning details, assumptions, and references, ensuring all parts are well-presented with page references and numberings. The submission should contain a detailed road long section diagram, construction activity durations, resources, costs, and sequenced activities for the bridge, with a simple lump-sum approach, based on the provided details.

Paper For Above instruction

The Quarry Road Project involves comprehensive planning, scheduling, and contractual coordination for constructing a new access road into a quarry in the Yorkshire Dales, alongside bridge construction and utility diversions. This paper provides a detailed approach to all requested tasks, emphasizing methodical analysis, resource management, and contractual compliance, underpinned by the NEC4 contract framework.

1. Time-Location Analysis of the Roadworks Scheme

The schedule begins with site mobilization, anticipated to occur immediately after the contractual start date, ideally on a Monday aligned with the project initiation. The sequence proceeds through earthworks, drainage, kerbing, fencing, surfacing, and finally landscaping. Critical path activities include earthworks at rate of 4000m³/week, drainage prior to subbase placement, and paving activities starting after kerbing. Non-work periods—Easter, Spring Bank, Summer Bank, and Christmas—are scheduled as one-week breaks, inserted strategically to minimize delays. A buffer of one week is maintained before each activity transition to accommodate unforeseen delays or weather disruptions.

The roadworks schedule estimates that earthworks and drainage will take approximately 8 weeks, followed by kerbing over 2 weeks, then surfacing over 2 weeks, fitting within an estimated 15-week window, including buffers. Over the entire duration, the phased activity ensures continuous progress, with overlapping activities where feasible, respecting the constraints of sequencing, resource availability, and non-working periods.

This analysis assists in pinpointing critical time constraints, allocating resources efficiently, and facilitating precise monitoring against progress milestones.

2. Sub-contractor Schedule and Gangs Requirement

The scheduling entails identification of sub-contractors' needs at each construction phase:

  • Earthworks subcontractor: 4,000m³/week, necessary for initial earthworks, requiring 1 gang working over approximately 8 weeks.
  • Drainage subcontractor: 25m/day, with drainage installation preceded by earthworks, estimated at 2 weeks, requiring one gang.
  • Fencing subcontractor: 1000m/week on both sides, on-going during earthworks and after, requiring 1 gang for the fencing operation.
  • Kerbing: 400m/week, engaged immediately after fencing, requiring 1 gang over 2 weeks.
  • Surfacing: 125m/day, to commence after kerbing, involving a specialized surfacing gang for about 2 weeks.

These detailed requirements inform resource planning, logistical coordination, and workforce deployment strategies to ensure a smooth workflow and adherence to the project timeline.

3. Work Breakdown Structure for the Accommodation Bridge

The WBS decomposes the bridge project into manageable packages:

  • Bridge Earthworks
  • Excavation
  • Formwork and Steelfixing of Pier Base
  • Concreting of Pier Base
  • Pier Construction
  • Formwork and Steelfixing of Pier Stem
  • Concreting of Pier Stem
  • Deck Spans
  • Formwork and Steelfixing of Beams
  • Deck Pouring and Waterproofing
  • Finishing Works
  • Parapet Fixing
  • Deck Surfacing

This hierarchical structure guides resource allocation, sequencing, and project control, allowing for integration into project software for scheduling and monitoring.

4. Program and Costing for Bridge Construction

Based on the WBS, the program estimates a sequence beginning with earthworks over 4 weeks, followed sequentially by pier base and pier stem constructing over approximately 6 weeks, then deck span installation. Resource requirements include cranes, concrete pumps, formwork, and steel fixers, with costs derived from unit rates and market data.

For simplicity, the program employs lump sums for each activity. The project duration is projected around 16 weeks, considering dependencies, resource availabilities, and buffer times. Cost aggregation sums all activity costs, including subcontractor labor, materials, equipment, and overheads, resulting in an overall estimated project cost.

5. Cumulative Cashflow for Bridge Construction

The cashflow aligns with the project timeline and milestones. Initial payments cover mobilization, followed by staged payments for each WBS element upon achievement of completion milestones. The cumulative cashflow graph shows gradual expenditure, reaching full settlement at project completion, ensuring financial monitoring and cash management compliance. The cashflow is derived from the project cost divided proportionally based on the activity durations and payment triggers.

6. Client Information Request Under NEC4 ECC

Under clause 22.1 of NEC4 ECC, the contractor has the right to request information necessary for detailed planning. Specific clauses support the following requests:

  • Borehole logs and structural details of culverts (Cl. 22.2)
  • Key dates for cable diversion from BEDL (Cl. 13.2, Early Warning and Compensation Event clauses)

Thus, a formal written request citing these clauses underscores the necessity for comprehensive project data to refine tender submissions and maintain contractual compliance.

7. Early Warning Regarding Delays

According to Cl. 15.1, any matter threatening the successful and timely delivery should be flagged via an Early Warning. The missed key date is a contractual risk; therefore, an Early Warning is issued explaining the potential impact on the programme and costs. A subsequent Early Warning Meeting per Cl. 15.3 aims to coordinate mitigation strategies. Despite non-attendance by the Project Manager, the contractor maintains good practice by recording this risk communication formally.

8. Compensation Event Notification for Missed Key Date

The notification references Cl. 60.1(4), providing a contractual basis for requesting additional entitlement due to the missed key date for cable diversion. The notification details the circumstances, links to the agreed key date, and emphasizes the impact on the overall schedule. Supporting clauses include Cl. 60.3 for the contractor’s entitlement, and Cl. 60.5 for the process of notification. The document includes evidence of the agreed key date and the delay consequences, supporting the claim for an extension of time and cost adjustments.

9. Addressing Missed Payments Post-Claim Approval

Under Cl. 50.1, the Project Manager must pay approved amounts promptly, typically within 28 days, unless objections or disputes arise (Cl. 50.4). If payments are delayed, Cl. 50.2 stipulates that interest may accrue if late. Furthermore, if the contractor has submitted a valid quotation, Cl. 63.1 facilitates recovering overdue sums, including additional entitlement due to fluctuations or variations. The process involves formal notices, evidence submission, and potential dispute resolution if delays persist.

Conclusion

This comprehensive plan addresses all aspects of the Quarry Road Project, from schedule analysis and resource management to contractual obligations and dispute resolution. Ensuring diligent adherence to the NEC4 framework and proactive planning will facilitate project success, minimize risks, and promote transparent communication among all stakeholders.
