Estuary Business Park

Estuary Business Park, Carrigaline, Co. Cork

This 30m diameter roundabout was designed and constructed as part of the development of the Estuary Business Park, Carrigaline on behalf of the development section of Cork County Council. Following a tender design competition, where applicants were required to submit potential designs for the site in question in addition to their fee proposal, MHL Consulting Engineers were appointed to carry out the detailed design of the site in accordance with the preliminary layout submitted.

Design Elements

The site is located adjacent to the R612 Crosshaven Road on the outskirts of Carrigaline. Given its proximity to the Owenaboy River and its associated estuary the flooding potential of the site had to be determined at an early stage. To this end a comprehensive flood study was carried out in association with Cork County Council and the impact of developing the lands assessed. A minimum finished design level for the various infrastructural elements was set accounting for the impact of global warming on tidal patterns into the future. This was followed by a detailed site investigation study to determine the level of imported fill required. In this instance it was possible to balance the cut & fill requirements of the site with capping material being the only imported earthworks required. To comply with sustainable urban drainage systems (SUDS) and to enhance the environmental quality of the site open ponds were incorporated for storm water retention. This system was designed in association with the Irish Fisheries Board to minimise disturbance to the existing river bed. During dry periods the ponds were designed to become a wetlands area with intensive planting of reeds and other water based plants being carried out. The result was a habitat for wildlife birds as well as being an amenity for the site. The construction of the infrastructural elements of the site was carried out by Martin O'Callaghan Contractor following a competitive tendering process. The development of the site took 1.0 year and was completed on time and within budget. To date a number of sites have been sold and buildings erected.

Crean’s Cross House Development

kenman — Mon, 01 Nov 2010 00:00:00 +0000

MHL provided engineering and civil design services for the planning and construction of this 2,400 sq.ft house located at Crean's Cross, Co. Cork. The site, located at the Crean's Cross junction of the R619 and the R579 required MHl to carry out a speed survey on the R579 as part of the provision of a detailed junction analysis required as part of the planning process. In addition a site suitability assessment to the latest EPA Code of Practice for Wastewater Treatment And Disposal Systems Serving Single Houses was carried out on the site. Our in-house architectural technician provided the client with a custom design for the house and garage.

Construction Stage The house is currently under construction using traditional concrete block with elements of steel to support open areas and the roof construction. The use of Ecojoists for the 1st floor allowed for greater spans and a reduction in the depth of bearing walls. In terms of achieving energy efficiency a 100mm cavity is provided, partially filled with 60mm of insulation giving a U Value 0.25 m²·K/W and it is proposed to dry-line the inside leaf of all external walls to further improve on the overall energy rating expected to be B1. The heating system proposed will use a condenser gas boiler supplemented by solar roof panels. In relation to sewage disposal the installation of a ECT-10 Eco Wastewater Treatment system achieving a final effluent standard of 20:30 (Biochemical Oxygen Demand:Suspended Solids) or better is proposed. Fully treated effluent is then discharged to the percolation drainage area. The location has a public water supply.

Signature Building Gouldshill Business Park Mallow

kenman — Sat, 15 Jan 2005 08:19:00 +0000

MHL provided the Engineering design for the Gouldshill Business Park Development

Following a public procurement process MHL were appointed as Design Engineers for the development of a Business Park at Gouldshill, Mallow by the development section of Cork County Council. As part of the competition process MHL submitted a proposed layout for the site which addressed key issues such as the steep gradient of the site, access proposals and servicing options. The brief outlined was to provide a sustainable design whilst adhering to the requirements of the client.

Following appointment MHL carried out a detailed topographical survey of the site followed by a preliminary site investigation to determine the suitability of the subsoil for road construction purposes. The primary aim of the design for the site was to optimise the available development land whilst minimising the cost associated with retaining walls and the impact on adjoining lands and properties. The final layout which proceeded to Part VIII planning in September 2007 was widely accepted as the best layout for the site.

Part VIII Planning

This Business Park Layout as shown includes for the provision of 23750 sq.m of Office Based Development and can cater for up to 950 number of employees. The project is to be developed using the latest environmentally friendly techniques and will rely heavily on intense landscaping and architecture to blend a very prominent site.
