Our team can provide a variety of different services to ensure the success of your project.

Pre-Construction Services
To ensure your construction project exceeds your expectations, HSI offers pre-construction services before actual construction work begins. This careful planning stage focuses on value engineering, constructability, and costing.

Construction Management Services
HSI can provide a fee-based service in which we, as your designated Construction Manager, are responsible exclusively to you the owner and act in the owner’s interests at every stage of the project. As your Construction Manager we will offer advice, uncolored by any conflicting interests, on matters such as:
· Optimum use of construction funds
· Scope of work
· Project scheduling
· Best use of design and construction firms skills and talents · Consultation on delays, changes, and disputes
· Enhancement of project design and overall construction quality

General Contracting Services
From inception to completion, whether hard bid or a negotiated project, HSI offers accountability for each project. An experienced Project Manager and Superintendent will be responsible for all phases of your project. We ensure that quality and scheduling are maintained at a high standard throughout the project. We strive to pursue a timely and efficient closeout for each project.

Design Build Services
From concept to completion, HSI provides ongoing leadership with hand picked teams comprising experienced architects, designers, engineers and subcontractors. From a single point of responsibility, design build unites experienced professionals to maintain a focus on budget while achieving a higher level of quality. Design Build Services include:

Value Engineering
HSI will be responsible for evaluating methods and materials to assure the team is designing the most cost effective project. Details of the structural, architectural, mechanical, electrical and civil elements of the project will be analyzed for alternates, which will be presented to the project team for their review. HSI will ensure a state of the art project at the most competitive price.

HSI understands the importance of maintaining a schedule. At the beginning of the project, HSI will produce a master project schedule showing the construction tasks. This schedule will be updated monthly.

HSI will review all relevant preliminary information in order to prepare a project specific conceptual estimate. Design Development drawings will be reviewed as well as consultant reports i.e. soils reports, Conditions of Approval and tenant criteria. A line item budget will be produced using historical cost data. Select subcontractors may be consulted. The project budget will be updated as project information matures and becomes available.

Plan Coordination
HSI will review the construction drawings for clarity and confirmation of previously agreed upon structural and architectural elements. Additionally, HSI will review construction requirements and review all drawings. A red line set of plans with comments will be produced and relayed to the Architect for inclusion with City plan check comments.

Bidding Subcontracting
After the project has been designed and construction documents are prepared, HSI will assist the Architect in preparing bid documents for subcontractor bidding. HSI will meet with the Owner to submit and review a list of subcontractors who would be invited to bid. HSI will provide all the information necessary for the subcontractors to prepare a comprehensive bid. HSI will provide the Owner with a final analysis of subcontractor bids that we believe will produce a successful project. The owner would be invited to help in the selection of the subcontrac- tors should they wish. Working with qualified subcontractors is a para- mount concern in maintaining quality of workmanship and scheduling.
