Tendering
In the construction industry, the tendering process is both time-consuming and fast paced. Nevertheless, little information is available at this stage and the expectations are always high. At the very beginning of the process, we believe the following points must be tackled for the bid to become sucessful:
- Understanding clients’ requirements and the project
- Setting a clear list of documents to issue.
- Attaching dates to all items.
- Constant follow-up through weekly meetings.
Quantities take off for structural works
Analyzing the structural drawings and specifications and preparing an approximate bill of quantities for individual members.
Phasing and sequencing for structural works.
Realistic high level phasing is developed in correlation with the planning of the project.
Presentations (2D and 3D) of construction phasing based on the planning.
Following the basic phasing, as per the clients requirements, a 2D or 3D presentation is produced, showing the site development, including also the temporary works (i.e. tower cranes, hoists, etc) as well as the actual building, along the timeline of the project.
Comparisons and financial evaluations
As the price of the materials is but a component of the total cost, we strive to consider all the elements to find the overall cost for the client.
Between the different financial solutions such as purchase, purchase + buy-back, rental or mixed and between different systems and solutions, taking into account the full costs, meaning actual price for the system, manpower, consumables, lost items, accessories and the duration of assembling, dismantling and moving the materials.
Taking the best financial decision requires a comprehensive comparison, putting in balance the advantages/disadvantages of the different solutions, considering the global costs, time-frame, geographic location and return policies. As the price of the materials is but a component of the total cost, we strive to consider all the elements in order to find the overall cost for the client.
Structure study and proposals for optimizing it with regards to its constructability.
Studying the structure in the tendering phase and proposing, wherever possible, an optimization with regards to its constructability, saving thus time, manpower and materials.
Defining the methods used for building the structure.
Site installation
Choice of structural solution (i.e. Precast VS Cast in situ) – wherever possible.
Tower cranes installation and dismantling planning / forecast.
Estimation of the tower cranes hook time analysis
Phasing for the earthworks.
Estimation for the temporary works needed to complete the project
Choice of lifting equipment: Tower cranes, mobile cranes, manual/electric winch, chainblock, etc.
Choice of vertical transportation/access: hoists, Mast climbers, MEWPs, Gantries.
Site facilities: offices, hoardings.
Choice of formwork (traditional (timber beams and steel wallings, panels, steel frames, climbing, self-climbing, slipform, bridges, tunnels).
Choice of scaffolding: tube & fittings, tube-lock, cuplock, ringlock, etc.
Scaffold solutions: load bearing, hanging, cantilever, special/custom-buit.
Access scaffold: Light, medium or heavy-duty working platforms, stairs, temporary walkways, alternative access.
Formwork and scaffolding quantities estimation and planning of deliveries.
Edge protections.
Loading decks (supported or cantilevered).
Propping and backpropping requirements for the project.
Safety platforms rotation and estimation.
Support to excavations, sheet piling.
Lifting plans
