ABOUT US


Autodesk Revit/ BIM Tool Autodesk Revit enables us to create 3D structural building information models. The model can then be transferred bi-directionally between ourselves and other members of the design team. It links seamlessly with the Masterseries structural design and analysis software so we can design and analyse the relevant structural members. Its great benefit is that it identifies constructional issues at the design stage which can then be solved and it ensures problems do not occur during construction.

Autodesk AutoCAD Civil 3D Civil 3D software is used for cut and fill modelling, detailed drainage designs, highway designs and 3D visualisations. In particular we can optimise the amount of cut and fill on a given site and use it to detect clashes in drainage runs. It provides project teams with comprehensive surveying, design and analysis solutions to deliver land development, transportation, and environmental projects faster and with improved accuracy.

MasterSeris Design and Analysis Suite MasterSeries provides a complete solution for the structural office, from analysis to design. It includes steel, concrete, composite, masonry, timber and retaining walls. The Masterseries 3D analysis and design software integrates with BIM using a Revit Interface.

WinDes Micro Drainage Suite Micro Drainage is software for modelling and simulation of drainage systems, SUDS (Sustainable Urban Drainage Systems) and Flood Hazards. It allows for the design of foul and surface water drainage systems, including flow control, attenuation, and infiltration in order to check the effective hydraulic operation of the system.

Autodesk Navisworks Autodesk Navisworks project review software helps us integrate, share, and review models and multiformat data with all project stakeholders. A comprehensive set of integration, analysis, and communication tools help us better coordinate disciplines, resolve conflicts, and plan projects before construction or renovation begins. Navisworks supports Building Information Modelling (BIM) for building and infrastructure, as well as 3D model-based design.

Adept uses the latest technology and best industry practices to deliver better projects for its clients. We use Building Information Modelling (BIM), 3D design, analysis and visualisation software on all our projects. We work collaboratively with all members of the design team to deliver efficient projects on time and in budget. Our experienced staff have been extensively trained in using these software packages and are both inspired and enthusiastic in implementing cutting edge solutions.

SolutionsThe office and assembly facility are linked via an internal atrium. Part of the design concept was for the internal environment of the office building to be cooled by natural ventilation utilising stack effect through a linear atrium that separates the office facilities from the main assembly building. The Atrium is dual functioned by providing natural ventilation and daylight to the deep floor plan of the office accommodation whilst housing the main circulation and access to the core at ground and first floor levels.The large open plan spaces complement the natural ventilation strategy which is combined with exposed concrete ceilings of Omnia type precast concrete slabs that are night time cooled by air circulation to provide daytime cooling to the internal spaces. The design concept for the scheme has been developed as a holistic approach that combines the best practices in all building consultancy disciplines. The office is

clad in white architectural Techcrete precast concrete panels, and a compositely designed steel frame is provided.The assembly hall is dual height of approximately 7m and 11m to underside of the roof formed from three steel portal frames. In addition, two gantry cranes within the structure were supported from steelwork independent to the main structure.The two storey office block building incorporated upper floors constructed from reinforced concrete metal decking with 225m rasied access floor typically supported on compositely designed steel beams. The ground floor construction for both areas is ground bearing fibre reinforced concrete slabs. The underlying ground was treated with lime and cement to improve the ground bearing capacity. All external works and drainage solutions were incorporated into the design.

Project brief To provide demolition details and site enabling works designs that had to be agreed with MAN, as they were still using the site for their operations whilst their new headquarters were being constructed. MAN Diesel sold its 30 acre site at Hazel Grove, Stockport to Commercial Development Projects in order to rent back a new UK headquarters building. The redevelopment included MAN’s new office, totalling 20,000 sq ft, as well as a 90,000 sq ft production unit with associated access roads, service yards and car parking - also home to MAN Diesel’s first UK Academy.

SolutionsThe existing facility housed engine beds used for testing submarine and ship engines. Adept managed to use some of these substantial bases as part of the permanent foundation design with the remainder of the building and offices supported on piles. The warehouse was a single storey, 10.5m high structure formed from twin span steel portal frames. The building contained a mezzanine floor, formed from metal decking supported on compositely designed beams. In addition, three gantry cranes within the structure were supported from steelwork independent to the main structure. The office building was a three storey steel framed structure incorporating upper floors constructed from reinforced concrete metal decking with 225mm raised access floor typically supported on compositely designed steel beams.

The ground floor construction for both buildings was suspended fibre reinforced slabs supported on driven cast in situ piles with flared heads.

A site-specific flood risk assessment was carried out by Adept. Floor levels and the drainage scheme for the site were based on the findings of this report, with large diameter surface water attenuation pipes provided to store and reduce surface water discharge off site in periods of heavy rain and relieve the burden on receiving drains and watercourses.

SolutionsThe original warehouse was constructed in 2004 on a reclaimed former opencast coal mining site, consisting of a clayey engineered fill. The existing building’s footprint had been dynamically compacted and therefore, due to the proximity to the existing building, dynamic compaction was not a viable option; vibro stone columns were used to achieve the 150kN/m2 safe ground bearing pressure required. Vibro treatment was viable up to 1.5m to the face of the existing buildings. A concrete plug was developed and applied to the top of the vibro columns to avoid water ingress to the clayey fill that could potentially have led to softening and a reduction in strength of the soils beneath the building footprint.

The external column bases were designed for a fire boundary condition and the large bases required were specified with concrete containing GGBS cement replacement, to control temperature during curing and to avoid cracks developing.

Existing surface water drains were diverted around the proposed building’s footprint due to vibro treatment works. The roof drainage was designed as a syphonic system to reduce below ground drainage.

Steel portal frames were designed plastically and tied in to the existing fully braced steel frame. Additional vertical bracing was added to the external elevations.

A steel fibre, reinforced, concrete ground bearing floor slab was provided on a DOT type 1 sub-base and geogrid was positioned over the vibro-treated ground. Racking leg loads in the high bay area were as high as 20 tonnes. Careful design bypassed the need to tie the steel columns to the floor slab and avoided the restraint that may have been caused as a result.

Project brief Adept were appointed on a design and build basis to assist in the construction of a new warehouse and showroom for Starplan Furniture. The scope of services included substructure, superstructure, external works and drainage design. The site was purchased from the Homes and Communities Agency and was previously used as a car park for the M62 Burtonwood motorway services; prior to that, the site was part of the Burtonwood airbase. The scheme was completed in September 2011.

SolutionsInitial reports suggested vibro treatment was likely but after further intrusive investigations, Adept determined that a more traditional pad and strip footing solution could be adopted for the building. The new building was of single storey steel portal framed construction with an internal mezzanine floor supported by a steel grillage; the ground floor for the building was steel fibre reinforced. Considering the historical use of the site the local authority environmental health team were involved during the design and specification of the scheme and we successfully obtained their approval to all works.

Planning conditions stipulated a low allowable discharge for surface water from the site. Adept designed a surface water storage pond to attenuate flows during heavy rainfall periods with headwall structures set to provide both ecological enhancement and to ensure the service yard did not flood during the design storms. The project was completed on time and to budget.

Project brief To provide civil and structural services including substructure, superstructure, highways and drainage design. Adept’s first major office development, Olympic Park, delivered 82,000 square feet of office space over 12 high quality commercial buildings built to a BREEAM very good accreditation and set in 10 acres of land adjacent to the M6. With the site being split in two by the Spittle Brook, careful coordination with the Environment Agency was needed to agree ecological and flood risk issues with regard to a new bridge and site levels. The scheme was completed in April 2008.

OLYMPIC PARK, BIRCHWOOD, WARRINGTON – OFFICE

SolutionsDue to varying ground conditions encountered across the site some units were built on stiff clay whilst other unit foundations were built off vibro-treated ground. The foundations to the columns of the two-storey offices were traditional mass concrete with external and internal blockwork walls supported on concrete strip footings, reinforced for the vibro treated units.

All the units were built with a structural steel frame designed by a specialist contractor. The internal beams to the first floor were designed compositely with a metal deck concrete slab. The first floor construction comprised a composite metal deck floor with reinforced concrete with computer floor over.

The site was susceptible to flooding and reports were required by the local authority to investigate this issue and the ecological impact of the development to Spittle Brook which crossed the site. The layout of the site, levels and bridge design were carried out with this in mind and two attenuation ponds were provided. Matters were further complicated by a high pressure gas main and adopted foul sewer running across the site in the vicinity of the new bridge. Coordination of services was paramount to ensure that sufficient working room was allowed around these existing services.

Project brief The project involved the construction of a single storey building to provide a swimming pool facility in Accrington. The swimming pool was to be of a standard which could be used for competitions.

ACCRINGTON COLLEGE SWIMMING POOL, ACCRINGTON – EDUCATION

SolutionsThe ground conditions at the site consisted of mudstone which was encountered at a variable depth beneath the made ground throughout the site. Beneath the swimming pool it was necessary to provide a consistent bearing strata to avoid differential settlement of the pool base, which was overcome by excavating out the rock in places and replacing with a number of layers of compacted engineered fill. All the foundations took the form of mass concrete foundations which were supported on the mudstone.

The superstructure was constructed using a steel framed solution with portal frames clear spanning over the pool. Lateral stability of the structure is provided by a combination of portal action and cross flat bracing. It was necessary to provide hot rolled steel purlins to the roof structure rather than the more typical cold rolled sections due to the aggressive corrosive environment provided by the

swimming pool. As a result of this environment it was also necessary to paint all the steelwork including the bolted connections and sag rods with a high specification anti-corrosion paint.

The pool itself was constructed using reinforced concrete with the concrete applied using the Gunite sprayed concrete technique. The concrete was sprayed from nozzles using special plant with the aid of high pressure air and built up using in a number of layers until the required thickness of walls and base had been provided. It was necessary to house a large tank beneath the ground slab as part of the pool water filtration system and consequently this area of the slab took the form of a suspended reinforced slab.

Project brief To provide a new modern entrance area, inspirational to both students and staff. This was to stand out from the traditionally constructed stone mill building it was serving by using large glass panels. The project was completed in 2010.

CARLTON WING, BRADFORD COLLEGE – EDUCATION

SolutionsThe project involved the construction of a glazed steel frame which formed an entrance to an existing mill building. There was previously no entrance at this location and part of this project’s challenge was to provide a suspended ground slab against the mill where an existing service walkway at basement level was evident. As a consequence, part of the ground floor was constructed in suspended reinforced concrete supported by the existing structure whilst part was ground bearing. It was also necessary to design the slab and foundations to avoid underground services which would have been very costly to divert. All the foundations were reinforced concrete ground beams founded onto sandstone. Adept worked with the contractor to keep the sub-structure as shallow as possible to minimise the excavation of sandstone.

The roof was a Kalzip standing seam sheeted roof fixed to steel purlins. The purlins were designed to be within the depth of the roof beams to maintain a shallow construction depth. A very slender steel framed construction was designed to achieve the architect’s aspiration.

Bracing was not allowed to the steel frame structure and structural stability was therefore provided by moment resisting steel frames with the base connection of the columns designed as fixed. The moment connections for the steel beams and columns were carefully designed so as not to intrude on the aesthetics of the structure.

Project brief To carry out a feasibility study with structural design and drawings for the renovation of the existing library building. The library now functions as the Learning Resource Centre, housing everything from a suite of computers, DVDs and CDs to around 25,000 books, covering everything from animal husbandry to strategic business management and economics. The scheme was completed in 2011.

SolutionsThe building required major renovation work to meet the client’s requirements, which included better circulation and the removal of a number of major load bearing walls, to provide more open plan, ground floor areas.

The building was two storeys high with the first floor built-in to the roof, as well as a line of dormers along the length. The roof was a mixture of both steel and timber trusses supporting purlins, rafters and tiles. The first floor was of timber construction supported on steel beams with both the external and internal walls being load bearing, solid brick masonry.

As part of the brief, Adept was required to carry out a detailed structural inspection of the building and a feasibility survey. Adept organised intrusive works to ascertain these structural details, basing their structural solutions on the results.

The existing staircase was removed then remodelled, and a new spiral staircase provided. New steel beams were installed to trim the existing floors around these openings, and detailed drawings and connection designs were provided by Adept. New foundations were designed for the staircases. Adept checked both the overall and local stability of the building structure.

Where the load bearing walls were removed, Adept detailed the temporary works which consisted of needle and propping, and designed the long span steel beams over the new openings which provided support to the timber floors above.

Project brief To provide a striking entrance and extension that would act as a focal point to define the ethos of the school’s image. Incorporated into the building was a wind turbine which was not only used to supply electricity to the school but was also used by the students to monitor wind speeds. The project was completed in 2008.

SolutionsThe site contained a large tree and as the soil was cohesive in nature the foundations needed to be carefully designed so that expansion/ shrinkage of the clay did not affect the structure in the future. In order to minimise the foundation depths to alleviate this issue, Adept designed the sub-structure as a reinforced concrete raft on granular fill which effectively halved the excavation depth, as opposed to a strip footing solution.

The curved perimeter wall was built using a reinforced concrete insulated polar wall type construction. This was adopted due to its flexibility to form the curved geometry requested. It was also favoured because of its speed to construct and the fact it was assembled using only lightweight material – thus, no heavy lifting or specialist equipment was required.

The construction took the form of two leaves of polystyrene polarwall panels with a 150mm reinforced concrete infill designed to cantilever from the foundations. To achieve the striking look required it was clad in timber.

The internal space needed to be free from columns and therefore the large spans of the roof were obtained by using 300mm deep TGI joists which were supported on the existing structure at one side and on the polar wall to the other. Curved clerestory glazing was constructed centrally within the structure, supported by a steel frame. The structural depths were kept to a minimum so as not to impose on the aesthetics of the building.

Project brief This recent expansion of the award winning Sixth Form College in Scunthorpe involved the construction of a new two-storey learning centre for Performing Arts, Music and ICT with an integrated single storey auditorium area. In addition the structure was designed to allow for future extensions along two of the wings.

SolutionsThe foundations were designed as concrete pad foundations and were mass concrete typically although the larger bases were designed a reinforced concrete to minimise the depth where possible. Also strip footings to one end of the structure were designed as ground beams which spanned on to the adjacent pads to minimise excavation.The structural frame was designed in steelwork and this supported a 130mm thick composite metal deck flooring to the first floor. The roof was formed from composite metal sheeting supported on cold rolled steel purlins. To the roof area there were a number of air handling units and air source heat pumps. It was necessary to provide an additional steel plant platform to support these units and a high degree of coordination with the plant suppliers was required to achieve this.The building envelope was clad in brickwork and rendered blockwork. The location of movement joints were

precious to the client and it was necessary for Adept to carefully detail the tie details of the masonry back to steel to achieve the client’s wishes.Adept produced a 3D building information model (BIM) for this project and all 2D drawings were generated from this model. This proved instrumental in the successful delivery of this project and both the Contractor and Architect saw great benefits in completing the project in this way. Any potential clashes were identified much earlier in the project than would have traditionally been possible which negated any costly alterations on site.

Project brief To refurbish the internal space so that it could function as a modern medical facility and also to provide a light rich and aesthetically pleasing entrance area to an existing building. The patients using the existing facility were relocated prior to construction commencing, however, a number of the administrators remained so it was necessary to coordinate all work carefully. Three community services operating in South Leeds were to relocate and use the building for their needs, alongside older people’s services. The project was completed in 2011.

SolutionsThe project involved a complete refurbishment to the ground floor of the medical centre, including the removal of a number of load bearing walls. Steel beams were introduced to facilitate the load transfer from the upper floors where load bearing elements were removed. The steel depths were designed to a minimum in order to maintain the existing service void. Adept worked closely with the architect to establish areas of remaining load bearing masonry piers. These needed to be structurally stable whilst also enabling the building to function correctly.

In addition to the refurbishment, a single storey entrance extension to the front of the existing building was constructed. To achieve the architectural vision, it was deemed appropriate to construct the roof using exposed glulam beams with a metal

sheeted roof over. The glulam beams, already fabricated curved, were supported on steel beams at the apex with galvanised mild steel shoes at their base. Careful detailing ensured the steel shoe detail and the steelwork was acceptable to both the architect and the client. The foundations took the form of a reinforced concrete strip footing to support the glulam roof structure, with the ground floor being formed as part of a reinforced concrete raft foundation.

Project brief To enlarge the existing medical centre by 210m² by constructing two new, distinctive, single storey extension wings, thus providing additional patient and staff capacity. In addition, the internal structure was altered to allow the building to be used as a modern medical centre.

SolutionsThe refurbishment to the existing structure was challenging to achieve as the original construction was load bearing masonry, with most of the internal walls continuing into the roof space to support roof purlins. It was necessary to carry out an extensive survey of the roof space prior to the design work, in order to advise the architect correctly with regards to what was achievable for the given budget. To one of the existing wings where all internal walls were removed Adept designed steel frames to support the masonry and roof above, whilst advising of the length the perimeter buttress piers needed to be to resist wind forces. The structural alterations in other areas were not as substantial and isolated steel beams from the existing structure were used where necessary.

The roofs to the new single storey wings were both constructed with a single-ply insulated membrane on timber ply on to timber roof joists. For the larger wing it was necessary to design steel frames within the building envelope to support the roof. It was essential to minimise the impact of the steelwork within the facility and to this end Adept designed the steel with fixed bases and carefully coordinated the moment connections with the architect. The smaller wing was designed utilising load bearing masonry construction.

All the new foundations were designed as mass concrete strip footings or concrete pads which were reinforced in some cases to minimise the excavation into the rock strata.

Project brief Adept were appointed by the developer to assist in the demolition of the existing Welcome Break services and construction of a new Travelodge Hotel, Starbucks coffee shop and Harvester public house. The scope of services included substructure, superstructure, external works and drainage design, with the offsite sewers adopted by United Utilities, and also advising on the demolition of the motorway services and proposed site master plan.

GEMINI 8 – PHASE 1, BURTONWOOD, WARRINGTON – HOTEL & RETAIL

SolutionsThe four-storey hotel was constructed using a timber frame which continued to the ground floor for part of the building and to a first floor steel transfer frame for the remainder; where there was a steel frame at first floor the deck at that level was constructed from concrete on composite metal decking. The ground floor for the whole building was a suspended pre-cast concrete floor supported on masonry walls and strip footings. The steel frame was supported on mass concrete pad foundations and all were built off the 600mm thick relic concrete runway of the former Burtonwood Airbase underlying the site. The timber frame, steel frame and pre-cast beam and block floor were designed by specialist contractors.

The coffee shop was a single storey, steel framed building built from a reinforced concrete raft, with the public house incorporating traditional pad and strip footings on ground that had been vibro treated.

As part of the development, a new infrastructure system was installed, with Adept being responsible for its adoption under Section 104 agreement of the foul and surface water sewers. A master plan was put in place where surface water run-off would be attenuated on a plot by plot basis as the scheme developed.

Project brief The project involved demolishing a former mill building on site which was surrounded by neighbouring properties, and the construction of a new six-storey building to be used as serviced apartments. The building façade required careful structural detailing to provide clear spans over ground floor retail units. Requirements also included shallow structural floor zones to keep within building height limits whilst incorporating services and minimal vertical bracing. The construction was completed in 2009.

SolutionsA detailed pre-demolition structural survey and risk assessment was carried out to ascertain details of party walls and methods for the demolition of the existing structure and the construction of the new foundations and their impact on neighbouring properties. Adept liaised closely with the party wall surveyor to resolve all issues efficiently and safely.

The new building consisted of six levels, including a partial basement, and was framed in structural steel. The roof was constructed from composite sheeting, the upper floors from concrete metal decking and the outer leaf of masonry was supported from stainless steel brackets at third and first floor levels. The ground floor was a suspended 225mm thick reinforced concrete slab supported on reinforced concrete ground beams.

The basement was constructed from a contiguous piled wall using 350mm diameter piles. A reinforced concrete wall faced the piles and a 300mm thick basement slab supported on ground beams completed the basement envelope. All facing concrete to the basement area had a XYPEX crystalline waterproof additive in lieu of a membrane which fulfilled the waterproofing requirement.

Due to poor ground conditions the structure was supported using a continuous flight, auger-piled foundation solution.

Lateral stability was addressed by a combination of cross flat vertical bracing generally with the addition of portal bracing. The project was completed on time and to budget.

Project brief To provide a building to serve the local community’s ecclesiastical needs whilst providing a self-financing business. Within the building a large auditorium, exhibition hall, a coffee shop, child day-care facilities and offices were required. Long span steel beams were needed over the auditorium as well as careful structural detailing where steelwork was exposed around light shafts. The building was completed in 2010.

SolutionsA large proportion of the building was single storey, which included a large auditorium and exhibition hall. There was a two-storey central section which incorporated offices.

A balanced cut and fill exercise was carried out across the sloping site to provide plateaus for the building and car parking areas.

The moisture sensitive clay fill beneath the footprint of the building was lime stabilised in layers to achieve the necessary allowable bearing pressure for the ground bearing slabs, as well as to provide a safe and firm working platform for the site works. Foundations were pad footings which were taken down to the natural clay. These were generally mass concrete, although the larger foundations, typically located at bracing positions, were reinforced to reduce their depth.

The building envelope was constructed from blockwork and brickwork, rendered blockwork or Metsec system walling.

The building was of steel framed construction with structural stability achieved by portalised frames and areas of cross bracing. The internal beams to the first floor were designed compositely with 150mm thick concrete on composite metal decking. The roof construction comprised of composite cladding.

Below ground surface water was discharged through a SUDS system, consisting of an underground surface water attenuation tank with a flow control device, restricting discharge to a nearby watercourse. The attenuation tank was in the form of a cellular system to the north of the site.

Project brief The provision of a significant multi-purpose church facility, accommodating an auditorium for 200 people, together with study and seminar rooms, day care facilities, a coffee shop and social meeting space. This additional accommodation has enabled the church to further develop its growing academy function and successfully extend its services to the local community and national organisations.

The roof was constructed using two-layer built up trapezoidal metal sheeting, supported on purlins and long-span steel rafters. A line of celestial windows was placed at roof level and a light-well continued through the first floor. The upper floors were constructed using composite metal decking supporting a

concrete slab with the ground floor being a reinforced concrete ground bearing slab. The walls were clad in stonework and render. A large, first floor terrace was provided and made water-tight.

Foundations to the building were mass concrete and reinforced concrete construction founded on shallow rock. The foundation interface between the existing and new buildings required careful detailing; also there were a number of existing drains that needed to be carefully diverted and kept live during the period of construction.

Lateral stability was generally provided by a combination of cross flat vertical bracing with the addition of portal bracing where required.

The project was completed on time and to budget.

Project brief To provide civil and structural design services for the conversion of existing facilities and the construction of new buildings and infrastructure at the original Robertson’s Jam factory at Ledbury, to create a new cider processing mill. Whilst the construction work was carried out, on-site food manufacturing had to continue which required careful logistics and planning. The scheme was completed in 2009.

SolutionsThe project involved construction of a number of production facilities, including a new boiler house, fermentation vessel farms and bunds, an effluent treatment plant and associated infrastructure. Adept was also involved with various alterations to existing production facilities on site, as well as a number of new ancillary buildings.

The new boiler house was situated on the position of an existing building and details had to be developed whilst this was functioning. A steel portal framed building was designed with traditional foundations.

The fermentation vessels were up to 30m high, stainless steel cylindrical structures. Adept designed the braced steel table frames which supported these vessels, the reinforced concrete bunds and the raft slab. The bunds were designed to meet the Environment Agency’s requirements.

The civil and structural design for the effluent treatment plant incorporated a reinforced concrete bund to contain the contents of various tanks and vessels contained within, to meet the Environment Agency’s requirements. There were also a number of large, reinforced concrete tank bases, complicated below ground drainage and a number of steel framed ancillary buildings.

Adept was also involved with a number of site inspections, advising on the feasibility of new construction and repairs to existing facilities, working closely with the client, architect, project manager and various civil, mechanical, electrical and process designers and contractors.

Project brief To develop a derelict Victorian building and construct two new buildings, both two storeys high, one with an additional semi-basement level as part of a new social housing scheme. The project was completed in 2010.

VALLEY COURT, CARDIGAN ROAD, LEEDS – SOCIAL HOUSING

SolutionsThe original building was in a state of disrepair as it had been occupied by squatters for a long period of time. Adept worked directly with the client, architect and the design and building contractor to identify savings across the site.

Initially, Adept carried out a detailed structural survey of the existing building and scheduled the required repairs where necessary. Adept designed steelwork to facilitate major alterations within the existing roof, in order to create a new flat within this space. In addition to this there were substantial alterations to the ground floor and first floor which created a further eight flats.

The scheme increased available accommodation by way of seven new flats and a standalone sheltered accommodation building. These were constructed with pre-cast concrete unit upper floors and a timber trussed roof. The foundations were designed as a reinforced concrete raft, provided to minimise the excavation into the sandstone ground strata.

Adept worked very closely with the project team advising on timber repairs to the structure as a whole and sympathetic masonry façade repairs. Adept was also involved in the waterproofing methodology to the existing and new basement in conjunction with the architect.

Adept offered savings on programme and cost by utilising efficient design, supported by 3D REVIT modelling. The scheme was Code 3 for sustainable homes compliant and Adept utilised SUDS in order to achieve this in part, alongside the provision of a pre-existing depression in the ground which served as an overflow.

Project brief To construct 27 family-sized homes as part of the first phase development of the site, 19 of which were made available for rent by Incommunities with the remainder retained for sale by the contractor. The development entailed 18 new three-bedroom and 8 two-bedroom houses plus one two-bedroom disabled bungalow. Building of the new homes was completed in September 2010 and formed part of Incommunities’ plans to regenerate the whole estate with the eventual construction of around 130 properties.

WOODHOUSE, KEIGHLEY – RESIDENTIAL

SolutionsThe development site was located on a steep hill which presented a number of challenges such as groundwater and cut and fill issues. Using the topographical survey and the architect’s proposals, Adept created a 3D model of the site in AutoCAD Civils 3D which enabled the contractor to accurately calculate earthworks quantities. Slight alterations to plot levels were suggested to reduce the quantity of material to be removed; due to the incline of the site, these changes to plot levels also helped to assess and reduce, where possible, the height of retaining walls across the site.

Underlying ground conditions varied across the site and foundation solutions included traditional strip footings, raft foundations and piled solutions. Non-traditional retaining wall types were used across the site that were either timber criblock walls or ‘Stepoc’ concrete fill walls that could be

constructed quicker than reinforced concrete walls and more economically. The amount of groundwater encountered during the works meant these alternative methods were well received by the contractor.

The SUDS drainage scheme was designed to be compliant with the Code for Sustainable Homes and also included amendments to the existing highway network in the area, which were carried out under a Section 278 agreement to the satisfaction of the local highways’ authority.

Project brief To assist the contractor, Strategic Team Group, during the tender process and throughout the development of 26 properties, consisting of bungalows, 2, 3 and 4 bedroom houses on a site previously occupied by dilapidated council offices. The scope of services included substructure, superstructure, highways and drainage design. The project was completed in August 2011.

EDWINS CLOSE, BARNSLEY – RESIDENTIAL

SolutionsThe relic foundations of the former council buildings created some challenges but were easily overcome with traditional strip footings across the site. The properties were constructed with load-bearing masonry walls, beam and block suspended ground floors, TJI type floor joists and trussed rafter roofs, providing a straightforward construction sequence for the contractor. Robust Details were also adopted into the design to ensure compliance with E1 of the Building Regulations.

The site was generally flat and consideration had to be given to the drainage solutions and floor levels to ensure sufficient falls were provided. The SUDS drainage scheme was designed to be Code for Sustainable Homes compliant and Adept prepared the necessary SUR1 and SUR2 reports

that met the code’s requirements. The scheme was further complicated by existing live drainage systems that had to be diverted and protected to ensure no flooding issues occurred.

The scheme also included a new highway network, designed and constructed under a Section 38 agreement to the satisfaction of the local authority. The site sewerage system was adopted by Yorkshire Water under a Section 104 agreement.

Project brief To construct a new, large, two-storey detached, timber-framed house on the site of an existing 1930s property. The client’s aspiration was to construct a high specification sustainable building with long clear spans and attractive architecture. The project was completed in 2012.

RED OAKS, ALWOODLEY, LEEDS – PRIVATE HOUSING

SolutionsThe new house consisted of a large, open plan kitchen with feature columns, a prominent, curved reinforced concrete staircase and accommodation to the first floor and within the roof space.A steel frame was installed to support part of the structure where clear open spans were required. Lateral stability to the steel frame was achieved using portalised bays and cross bracing where possible. Outside the footprint of the steel frame, timber stud framed walls were used to support gravity loads from the timber open web joist first floor construction and the roof trusses. Wind loading resistance was achieved with timber frame racking panels that used Orientated Strand Boards (OSB) as a diaphragm. The first floor construction comprised of open web joists which supported OSB flooring with a lightweight screed topping. The external walls were clad in brick masonry with openings of up to 5m span and Crittall-type steel window

frames were installed that required tight deflection limits.Traditional reinforced concrete pad and strip footings were used as a solution to the house’s foundations, together with a reinforced concrete ground bearing slab.

Project brief The brief was to provide civil and structural engineering services for a restoration project within a conservation and green belt area to rebuild a fire destroyed, grade 2 listed canal side mill, converting it into eight 2-4 bedroom houses. The scheme was completed in 2011.

CLEGG HALL MILL, ROCHDALE – PRIVATE HOUSING

SolutionsClegg Hall Mill was extensively damaged, with only one gable and a corner left standing; the entire floor structure and roof perishing in the fire. The plot was positioned on a narrow site with a retaining wall holding up a cobbled road to one side and the front of the property mainly formed on the canal wall. The new houses were built as four-storey properties incorporating a semi-basement lower ground floor fronting the canal side, the ground floor level offering access from the road with first and second floors within the roof space.

Adept was tasked with reviewing the architectural design to provide structural solutions. The external wall foundations of the former mill were investigated and found to be satisfactory for the new proposed loads. A combination of new and existing foundations supported the new walls which were built as load bearing masonry up to ground. On-site inspections were carried out to review existing ground conditions and foundation requirements relating particularly to the existing stone masonry retaining walls. A precast beam and

block floor were used at lower ground floor level which had to span over a culvert locally.

The upper floors were constructed using a load bearing, timber stud framework designed by Adept and specially-designed open web joist timber flanged beams. Hot rolled steelwork was used to support timber framing at floor levels, where necessary, and at roof level as purlins, to create accommodation within the roof space whilst supporting the complicated roof geometry.

Externally, the mill was rebuilt using locally sourced natural stone walls and slate roofing, together with high performance softwood windows manufactured locally in Littleborough.Due to the nature of the varying existing floor levels and window openings, each property had its own unique internal layout, creating very interesting living spaces. Each property also had either an exhaust air or air source heat pump installed to engage the most efficient use of renewable energy, supplying the under-floor heating and hot water of each dwelling.

TRINITY VIEW RESIDENTIAL DEVELOPMENT, LEEDS – PRIVATE HOUSING

SolutionsTrinity View is a sympathetically restored Baptist Church which has been skilfully converted into 13 stylish apartments, offering such features as exposed timber purlins, original stained glass windows, exposed stone and brickwork and an uncompromising attention to detail.

Adept carried out a detailed structural site inspection and feasibility study for the proposed work. The proposed structural design works were sympathetic to the historical fabric of the buildings.

At roof level to the annexe, the bottom booms of two existing timber king post trusses were at a level that was too low for the proposed flats. Adept designed a steel portal frame solution using two Parallel Flanged Channels which were bolted through the existing truss. This also solved the temporary works issue and no propping was required.

The flats were designed with engineered timber floor joists, spanning existing and new load bearing masonry walls. Steel beams were installed to support the floors and walls in certain areas.

New and existing strip footings were used to support masonry walls. Partial underpinning was applied to the basement where the headroom needed to be increased, as well as the introduction of a tanking system.

New foul and surface water drainage was designed. Adept was involved in discussions with Yorkshire Water in relation to an adopted drain which crossed the site.

Project brief To construct four new high quality mews properties along with new luxury apartments in a three storey building constructed on the footprint of the existing lodge in the heart of Roundhay. Building work was completed in December 2011 and formed part of the clients plans to further develop the adjacent site with further luxury properties planned for 2013.

BEECH LODGE, ROUNDHAY – PRIVATE HOUSING

SolutionsAdept used Autodesk Revit Structure as a Building information Modelling (BIM) solution to model all the buildings and provide detailed isometric views and construction details of the complicated roof geometry to the lodge building.The mews properties presented few problems. The construction consisted of traditional load bearing masonry walls, suspended precast ground and first floors and roof level accommodation framed using steel beams and purlins; together with timber rafters and joists.The whole of the front façade of the existing lodge building needed to be retained due to planning requirements with the remainder of the existing lodge being demolished. To complicate matters further a basement was to be constructed in the new lodge building meaning the existing façade needed underpinning. Adept developed detail drawings showing façade retention and underpinning requirements.

The client insisted on exceptional quality of build throughout and the roof to the new apartment block was no exception with a complicated steel roof structure providing the space for the luxury penthouse apartments. Offsite fabricated dummy chimney units were detailed by Adept to simplify construction of these elements of work.Underlying ground conditions were favourable with the site underlain by sandstone bedrock which as well as providing good ground bearing strata also provided excellent infiltration characteristics. The SUDS drainage scheme was designed to be compliant with the Code for Sustainable Homes. A new access road was constructed in to the site to adoptable standards and also drained to a SUDS system in the form a soakaway adjacent to the carriageway.

Project brief The project involved the construction of a substantial extension to a house previously owned by Mr Leslie Silver at the above address. The house was extended to an area of over 1800m2. The building consisted of three storeys above ground level which included attic accommodation, eight bedrooms with ensuite facilities at first floor; kitchens, reception rooms, living rooms, indoor swimming pool and a study at ground floor. Also there was a basement level which included a gym, changing rooms, Turkish Bath, Sauna, and a home theatre cinema. The basement area was constructed under a quarter of the building footprint.

BRACKEN PARK LODGE, SYKE LANE, SCARCROFT – PRIVATE HOUSING

SolutionsThe original buildings consisted of a two storey main house, and a number of linked single storey buildings including a games room, swimming pool and double garage, with a total area of approximately 400m2. As a substantial new basement area was required below the footprint of the original construction a detailed structural investigation and survey was carried out to provide an economical solution. Underpinning was carried out to the existing property which was occupied during the work been carried out.The swimming pool construction was retained and underpinning was provided at new column positions as a steel frame was provided over the pool to support the new first floor and roof construction.

Generally the building was load bearing masonry with independent steel beams to support precast concrete beams at first floor with timber attic truss construction at second floor level to keep the self weight low. It was necessary to have all the steel beams within the floor depth in order that downstand beams were not featured within the property. The roof was formed with timber attic trusses.Due to the rural positioning of the property a package bio-treatment plant was provided and new foul and surface water drainage was provided.

Project brief The project involved the construction of a new contemporary house. The property which is built on a sloping site consists of a three storey building. The architectural brief called for a lower ground floor level which contains a garage for four cars and a gym in addition to guest living accommodation. At ground floor living rooms and kitchen diner is provided with bedrooms at first floor level. As part of the architectural brief extensive use was made of timber and glazing that provides distant panoramic views, as well as sustainability objectives including PV panels installed on the flat roof.

ROMBALDS STRIDE MAXWELL DRIVE, ILKLEY – PRIVATE HOUSING

SolutionsThe house is positioned on a sloping site overlooking Ilkley near the Cow and Calf site. The site investigation carried out revealed weak and variable ground conditions due to glacial deposits with considerable ground water across the site. The foundation solution chosen incorporated a reinforced concrete raft slab construction which was integral with the reinforced concrete retaining walls constructed. This also allowed for an externally tanked water proofing system to be installed.Generally the building is of load bearing masonry construction with the exception of the reinforced concrete retaining walls to the lower ground floor level. Independent steel beams were provided to support precast concrete hollowcore units to

the ground floor, first floor and flat roof. It was necessary to keep all the steel beams within the floor depth in order that downstand beams were not featured within the property.

As large sections of glazing panels were provided to external walls; steel wind posts were introduced to provide stability to the external masonry panels.

A specialist contractor designed spiral staircase with glass treads which was provided to link the floors. A steel frame was provided to the feature timber clad rear balcony terrace structure, which was suspended from the roof level at specific positions.

Project brief The project involved the design of a substantial new build property for a member of the Abu Dhabi Royal Family. The main residential block consisted of over 4000m2 floor area.

SolutionsThe buildings had a demanding architecture led form. Collaboration was required between Adept and various parties including the architect who was based in Singapore, the main contractor in UAE and the steel fabricator in Turkey.The floor construction typically consisted of composite steel beams supporting a composite metal deck flooring system supporting a reinforced concrete slab. Steel sections were modified through the design to locally available sections.

The design had to include for a seismic analysis and the Earthquake Loading used for Seismic Analysis was based on the UBC 97 standard. At first floor level over the main entrance a 200m2 reception area was required to hang off roof level trusses

such that when viewed from below it appeared suspended in mid air with no supports around it. At ground floor level entrance area a water feature was provided under this area with walkways forming a crossing. The steelwork and reinforced concrete details had to be resolved to solve various issues.

The library structure also had novel steel framing arrangements to achieve column free construction together with the use of cross shaped columns.This project for which design work was carried out in 2008 was Adept Consulting Engineer’s first project using Autodesk Revit BIM software which integrates with the Masterseries structural analysis and design package. Extensive use was made of 3D visualisations to communicate design intent.

SLATER HOUSE, FULLWITH MILL LANE, HARROGATE – PRIVATE HOUSING

SolutionsThe land used for the construction of the building contained a number of trees which some were to be removed whilst the remainder were retained. As the ground bearing strata was clay, the foundation solution had to be carefully engineered to alleviate clay heave issues due to the trees that were removed. Through a value engineering exercise and discussions with the project team Adept Consulting Engineers adopted a reinforced concrete raft solution as this minimised the excavation required as opposed to using traditional strip footings as well as the requirement for a suspended floor. This was concluded to be the most cost effective solution and saved over £25,000 for our client.Generally the building is load bearing masonry construction with independent steel beams to support precast concrete hollowcore units at

first floor with timber floor construction at second floor level to keep the self weight low.

It was necessary to keep all the steel beams within the floor depth in order that downstand beams were not featured within the property. The roof was formed with timber joists supported on steel beam purlins.

The swimming pool area was single storey only but required large open spans with no internal columns. As a consequence two feature timber trusses were used to form the main structural support with exposed timber purlins supported off these. All steel to this area had to be protected with a high paint specification to stop corrosion due to the aggressive nature of the swimming pool atmosphere.
