Didcot is a growth town wrapped around a railway and a former power station site, with the A34 on one side and the A4130 carrying everything else. We design temporary traffic management for that infrastructure mix, get it approved, and install it with our own crews.

Possession dates, outage windows and delivery slots do not move, so the traffic management has to be approved and resourced to match. We work across the town and its edges: the centre and Broadway, Ladygrove, Northbourne, Great Western Park, Didcot East, plus Milton, Sutton Courtenay, Appleford, Culham and Harwell nearby. The corridors that shape schemes here are the A4130 through the town and west to the A34 Milton interchange, the A34 itself, the B4493 towards Sutton Courtenay, the A417 towards Wantage, the A415 north through Culham, and the level crossings and rail bridges that constrain routing throughout. Typical work includes site access and haul route arrangements on Garden Town housing phases, deep utility and drainage excavations, closures for crane lifts and abnormal loads serving infrastructure sites, signals for single-lane working on the B-roads, and overnight lane closures on the A4130 and A34 delivered under Sector Scheme 12D.

Local conditions ## What goes wrong on Didcot schemes Didcot punishes schemes that are planned like ordinary street works. The constraints here are infrastructure constraints. ### Fixed windows that cannot slip Rail possessions, outages and delivery slots are booked far in advance. If the permit or TTRO is not approved in time, the window is lost, not delayed. We work backwards from the window, allowing for statutory notice periods, and confirm approval in writing rather than assuming it will land. ### Level crossings and rail bridges The rail corridor limits crossing points, and bridges bring height and width restrictions that quietly invalidate diversion routes. Every diversion is driven and checked for width, height, weight and turning before submission, particularly where HGVs or abnormal loads are involved. ### Abnormal loads and heavy plant Infrastructure works bring components and plant that need swept path checks, temporary sign removal, escorting and sometimes short full closures. These are designed movements with agreed routes and timings, not something to arrange on the day the load arrives. ### The A4130 as the town's spine Most Didcot traffic uses the A4130 to reach the A34, so works on it queue quickly and affect the interchange. Arrangements here need advance signing, realistic timings and often night working, with lane closures preferred over full closures. ### Growth-area construction traffic Garden Town housing phases push construction traffic through estates where people already live, generating objections and safety concerns around footways and school routes. Designed access points, haul routes and protected pedestrian routes are part of the scheme rather than an afterthought. ### Deep excavations and drainage Low ground and large service diversions mean deep, long-duration excavations that change shape as the work proceeds. We maintain the arrangement through those changes, including out of hours, and reissue drawings when the layout genuinely changes. Our process ## How a Didcot scheme gets fromenquiry to signed-off completion 1. Step 1 ### Enquiry and site review You send the location, the works and the dates. We check the road type, the speed limit, the highway authority involved and any local constraints before quoting. 2. Step 2 ### Scheme design and CAD drawing We produce the temporary traffic management design and scheme-specific CAD drawings for the arrangement your works actually need, not a generic layout. 3. Step 3 ### Permits, TTROs and authority approval We submit to the local highway authority and manage the process end to end — permits, Temporary Traffic Regulation Orders, notices and conditions — and confirm approval in writing. 4. Step 4 ### Programming and resourcing Crews, signals, signage and barriers are allocated from our fleet of around 150 vehicles and team of around 300, and booked to the dates you have been given. 5. Step 5 ### Installation by our own crews Carded and ticketed operatives working under our supervision install to the approved drawing, with the arrangement checked against the drawing before works start. 6. Step 6 ### Maintenance, phase changes and collection The scheme is inspected and maintained, damage and displacement dealt with including out of hours, phases changed as planned operations, and everything collected at completion. ## Standards we work to in Didcot - Sector Scheme 12 — 12A, 12B, 12C & 12D - Chapter 8 (Traffic Signs Manual) - New Roads & Street Works Act (NRSWA) - Lantra/NRSWA cards, T1/T2/T3 tickets - £10m public liability & £10m employers' liability insurance ## Accreditations held - National Highway Sector Schemes - Constructionline Gold - BM Trada - CHAS - Acclaim - Achilles UVDB - Avetta - Builder's Profile - SafeContractor - ISO 9001 Certificates are issued for your pre-qualification pack on request.

How quickly can you reach Didcot? It is a short run from our Oxfordshire base via the A34 or A4130. Planned works are booked to your dates and emergency call-outs are attended 24 hours a day, seven days a week. Can you work on the A34 and the Milton interchange? Yes. Those are high-speed schemes delivered under Sector Scheme 12D registration by ticketed crews, with correct taper lengths, safety zones and advance signing, normally in overnight windows and involving National Highways alongside the county council. Which roads do you most often work on in Didcot? The A4130 through the town and out to the A34, the A34 itself, the B4493 towards Sutton Courtenay, the A417 towards Wantage, the A415 through Culham, and the estate and haul roads serving the Garden Town growth areas. Can you work to rail possession and outage windows? Yes. We plan the permit or TTRO timeline backwards from your window, allow for statutory notice periods and resource crews for night and weekend shifts so the arrangement is in place when the possession starts. Do you handle abnormal loads and crane lifts? Yes. That includes route checking for width, height, weight and swept path, short closures where required, escorted movements and reinstating the normal arrangement afterwards. How much does traffic management cost in Didcot? It depends on the road, the arrangement the authority will approve, the equipment, the duration, whether operatives remain on site and the council's permit or TTRO fees. Infrastructure schemes with night working and diversions cost more than a short daytime footway closure, so we price each one in writing. Do you handle the council paperwork? Yes.
