Description of the contract

Brodsworth Hall – located 11km north-west of Doncaster – is an outstanding example of a Victorian country house. It was built between 1861 and 1863 and has survived with most of its interior fittings and furnishings. It is listed under the Planning (Listed Buildings and Conservation Areas) Act 1990 as “Grade 1” and was acquired by the State in 1990 and is currently managed and maintained by English Heritage. The house is constructed out of soft pale magnesian limestone – which was sourced locally – and is built in a restrained Italianate style on a T-shaped plan. The main block is long and of only two storeys with a shorter lower servants wing to the rear. Each side of the house is symmetrical with features such as: false windows; moulded string courses and cornices; projecting bays and the columned ‘porte cochere’. It has a rusticated lower floor and projecting quoins above; the ashlar stonework to the upper storey has aprons; architraves and segmental pediments to windows; and a modillioned cornice with balustrade of terracotta balusters and urns in turn contrasting with a solid parapet arrangement above the projecting bays. In the early 1990’s the property underwent a major programme of restoration and conservation prior to it being opened up to the visiting public in 1995. This work was necessary due to the poor state of the fabric which had suffered under its previous tenure from years of inadequate maintenance. Typically the magnesian limestone cladding had suffered erosion due to acid rain and this damage was repaired by replacing extensive areas of stone and careful cleaning to remove harmful pollution deposits. This current project forms the second element of a series of works required to address essential repairs to the exterior stone work to the main house at Brodsworth Hall which were identified following a condition survey carried out in 2010. The first phase of repairs which were undertaken in 2011/12 were limited in their scope and focused on a small portion of the exterior. This second phase of repair works has been fully scoped up by the Design Team following a comprehensive assessment of the initial phase and the aim is to address the remainder of the masonry repairs. The masonry repairs proposed will cover the replacement of badly eroded ashlar stone work as well as indent and mortar repairs to the face work and coping stones. It will also address grouting and re-pointing works and protective shelter coats as well as making good failed repairs arising from the 1990’s consolidation works. The project also aims to carry out structural repairs to cracked window head lintels and pin back fragile feature stones where fabric is at risk. For continuity of workmanship and best practice these repair works are to be undertaken as one continuous campaign of work during the 2013/14 fiscal year and a sequence of works which fits around the visitor operations and presentation of the site has been established. It is therefore imperative that the contractor undertaking these works is able to fully resource the project in order to address this requirement. Consequently previous experience of successfully delivering similar intricate conservation projects is vital and there will be a need for all applicants to this notice to have – and to be able to provide detailed evidence of – a competent track record in working upon historic buildings and their environs which will be vetted and scored via a pre-qualification process in order to establish a tender short list. Applicants are asked to note that all construction works are subject to the conditions and restrictions set by Listed Building Consent. The Contractor will be required to undertake the duties of “Principal Contractor” under the CDM Regulations 2007.
