Lark’s has a wealth of experience in stipulated sum contract models. It is a perfect approach designed to reduce design and contract administration costs.
A stipulated sum contract is a great contract agreement to be used if the requested work is well-defined and construction drawings are completed. The stipulated agreement will reduce owner risk. It is also a preferred choice when stable soil conditions, complete pre-construction studies and assessments are completed and the contractor has analyzed those documents. The stipulated sum contract might contain, when agreed-upon parties, certain unit prices for items with indefinite quantities and allowance to cover any unexpected condition. The time to award this type of contract is also longer; however, it will minimize change orders during construction.
A lump sum contract offers the following advantages:
• Low risk to owner.
• ‘Fixed’ construction cost.
• Minimize change orders.
• Owner supervision is reduced when compared to Time and Material Contract.
• Contractor will try to complete the project faster.
• Accepted widely as a contracting method.
• Bidding analysis and selection process is relatively easily.
• Contractor will maximize its production and performance.
Lark leads the way in virtual construction using, fully integrated 3D, 4D and 5D BIM technologies and workflow to control the project from design through to completion.
A fundamental reason why Lark has taken the initiative to be at the forefront of BIM technology is to maximize the value that BIM brings to Owners. We call this True BIM. It starts with our in-house capability to produce accurate Construction models, building the model in detail floor by floor and adding construction means and methods. We use schedules within Revit to monitor the design development and Trimble Vico software and processes to control 4D (scheduling) and 5D (costs). Vico is the most integrated BIM software and any changes to the model automatically update the impact on cost and schedule.
The “As-Built” BIM model at a Level of Development 500, is populated with relevant building component information such as product data, O&M manuals, cut sheet specifications and warranty data.
During Design Development the Architectural Revit model will be used for program validation and will be developed from LOD 200 to LOD 300. A Model Progression Specification (MPS) will outline the modelling protocols in detail. Included in the MPS will be Revit Family naming conventions for seamless downstream use in 4D and 5D processes using Trimble Vico software. The LOD follows the guidelines set out in AIA Document G202 – 2013
The Architect’s model will be handed on to the Structural Engineer, to verify the structural elements. The Structural model will then also be developed to LOD 300. By that stage the MEP design should be complete and those models also produced to LOD 300. These are data rich BIM models, not just visual 3D representations of the building. The common programs used are Autodesk Revit. In addition to the design models created by the design consultants additional software may be used for Energy modelling and Structural analysis.
From Design Development to the completion of Construction Documents the models are continually compared for clash detection to assist with coordination. This clash detection process is initially run in Revit, and subsequently using Trimble Vico software. In combination with hard and soft clash detection, Lark also has an established best practice for Constructability Analysis. By building the project “virtually” in Revit using 2D drawings for reference, we are able to conduct constructability analysis, identify missing information and add means and methods. This is our Construction model. On a number of projects, we have shown to significantly reduce the number of RFI’s and changes during construction.
We log and track every clash and constructability issue until each is resolved. During construction we use the 3D models to enhance communication, and as a reference for dimensions and elevations. In congested ceiling spaces we often produce colour coded construction drawings for Mechanical and Plumbing layout, using accurate information from the fully coordinated Mechanical model.
LARK uses Vico software to produce a “Flowline” schedule for production planning and control. A flowline is a graphical representation that shows the movement of crews through locations. This is a Location Based Management System (LBMS) that uses Line of Balance theory to optimize work flow and productivity. The schedule is driven from the 3D model quantities and our proprietary database of production rates, and so any changes in the 3D model will be automatically reflected in the 4D schedule.
Vico is not only a superior planning tool, but is also highly effective in controlling the schedule during construction. Actual production data is captured every few days and the schedule calculates a forecast based on the actual production trend. This allows the team on site to be proactive and to take corrective actions very quickly if needed.
5D QUANTITIES AND COST MANAGEMENT
We use Vico software to generate accurate quantities from the models by location to support estimating and scheduling.The quantities are extracted directly from the 3D model and so any changes in the model (changes in design) are automatically reflected in the quantities and cost plan. This helps with cost management during design, and having accurate quantities also helps reduce waste during construction.
Successful PPP Projects always emphasize the final P. Solid partnerships with all stakeholders. Partnerships with the Health Authority, Municipal Authorities, Lenders, User Groups, Operators, Consultants and Sub-Contractors are key to our success in both Public Private Partnership projects by coordinating and managing competing demands for an optimal solution that satisfies all of the parties to the deal. These win-win arrangements foster long-term relationships that remove risk and make the process rewarding and enjoyable.
Lark develops award-winning institutional projects under the PPP model by synthesizing the best of evidence-based design (EBD) and patient-centered care, while delivering the services and features that our clients need. Quality project delivery has allowed the Lark Group to build relationships with various sectors that we value highly, and that allows us to continue to building our expertise in the PPP arena.

Lark’s construction management approach provides a collaborative environment in which the Owner, Consultants and Construction Managers work as a team to find the best solutions. These solutions can be quickly turned into results delivering the project in the most efficient manner possible. This efficiency translates into a balance between cost, schedule and quality. Lark’s process is completely open book where the owner is in an informed position throughout the life of the project and involved in the decision making process.
Establishing the project requirements for quality begins at project inception. A careful balance between the owner’s requirements of the project costs and schedule, desired operating characteristics, materials of construction, etc. and the design professional’s need for adequate time and budget to meet those requirements during the design process is essential. Owners balance their requirements against economic considerations and, in some cases, against chance of failure. The design professional is obligated to protect public health and safety in the context of the final completed project. The constructor is responsible for the means, methods, techniques, sequences, and procedures of construction, as well as for safety precautions and programs during the construction process.
