The Quarry Road project

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 roadworks site must be secured by temporary or permanent fencing prior to earthworks starting on any sections of cut or fill.

Surplus cut or fill will go to or come from the quarry.

There is to be a one week buffer between all roadworks operations.

Accommodation Bridge

The Accommodation Bridge is part of the Quarry Road Project.  All bulk earthworks must be completed before the bridge construction can start. Your task is to plan the construction of this bridge and determine resource requirements.

To keep the planning relatively simple, ensure that the construction is in “lumps”.  It is appreciated that there ought really to be much more detail but time is against us!

Some Construction details:

We are in an area of fine Yorkshire sandstone so base construction is directly on to bedrock.

The North and South Bank Seats are exactly the same construction.

The North and South Pier are all exactly the same construction

Bank seat construction comprises Excavation, Formwork, Steelfixing and Concreting plus fixing bearings

Pier construction comprises Excavation, Formwork, Steelfixing and Concreting to the base and Formwork, Steelfixing and Concreting to the stem plus fixing bearings

Each deck span comprises 10 beams with a concrete slab on permanent formwork and is to include parapet fixing, deck waterproofing and deck surfacing.
